Ruset: seen with graphviz from eg
Swish is a framework, written in the purely functional programming language Haskell, for performing deductions in RDF data using a variety of techniques. Swish is conceived as a toolkit for experimenting with RDF inference, and for implementing stand-alone RDF file processors (usable in similar style to CWM , ...).
In fact business rules are raw material for the building of business applications just like ontologies and structural models. And, because we build business applications using rules (applicative and infrastructure rules), this means having rules manipulating rules.
We already have such rules manipulating rules to :
We need to have more rules manipulating rules to :
Point 1 will stay like this in the near future, as current implementation is well tested and extensible.
The point 2 is necessary for automating access to Linked Open Data (see Roadmap for EulerGUI 2.1 , and Sketch of a roadmap / The Déductions stuff in my blog).
We need to design and implement a backward engine for querying SPARQL databases; it will generate a big SPARQL query by recursively accumulating criterium terms, substituting bound variables, renaming variables if necessary.
I used to think that for point 2, the capabilities of Euler or CHR to handle unbound variables can be leveraged. But I changed my mind. Since I already have experience with dealing with SWRL, it ' s probably quite easy to first convert the N3 to SWRL. Good thing with SWRL is, it's plain RDF, and as a consequence there's no possible confusion between input rules and transformation rules (this is actually a problem when processing N3 with N3). It's also easier to match rule parts when the rule is expressed as pure RDF graph (SWRL or other). So SWRL just a quite simple RDF rule format, enough well documented (but I din't have to reed the doc. to write the SWRL ==> N3 converter rules ). N3 is suitable for writing rules by hand and proof-reading by developers (and directly interpretation by any of the EulerGUI.
So the roadmap for this SPARQL generation feature could be :
As an exemple, think of a family relationship rule base (see rules examples - Family relationships ). The intermediary steps are writen below in N3, but keep in mind that the actual inferencing will manipulate SWRL syntax, as explained above (point 1).
Starting from a simplified N3 query :
:John :hasUncle ?U
By 3, this rule is picked:
{ ?X hasParent ?P . ?P hasBrother ?B . } => { ?X hasUncle ?Y }.
By 3, substitute variable ?X with its value :John :
{ :John hasParent ?P . ?P hasBrother ?B . } => { :John hasUncle ?Y }.
By 4, the rule for hasBrother is picked, and the antecedent is substituted in preceding rule :
{ :John hasParent ?P . ?P hasSibling ?B .
?B a Male.
} => {
:John hasUncle ?Y }.
For property hasParent
, a background declaration states that
the corresponding triples are hosted in some SPARQL endpoint:
hasParent eg:inSPARQL_endpoint <http://mydatasource.org/> .
So, no need to recurse on property hasParent.
Similarly, for class Male
, , a background declaration states
that the corresponding triples are hosted in some SPARQL endpoint:
Male eg:inSPARQL_endpoint <http://mydatasource.org/> .
Process goes on with expanding hasSibling .
When nothing is left to be expanded, it's time to use point 2 above to generate the final SPARQL query.

Programming the Semantic Web
Build Flexible Applications with Graph Data
By Toby Segaran, Colin Evans, Jamie Taylor
http://shop.oreilly.com/product/9780596153823.do
Rules are not only for business rules, but also for reasonning on computing infrastructure : GUI, data sources, network protocol, access control and permissions, logs, cloud and IAAS, PAAS .
For instance, with swing3 rule base, we generate in real time Swing input forms from OWL ontology.
Another example (not yet implemented) : knowing details on data sources, their content in terms of properties, classes, ontologies, whether they are trusted, it is possible to manage querying : e.g. generate SPARQL queries on selected sources depending on business rules.
sparql parameterized queries in Andy's blog
This should be used in EulerGUI !
QuerySolutionMap initialSettings = new QuerySolutionMap() ; initialSettings.add("title", node) ; // and this is passed to the factory that creates QueryExecution's: QueryExecution qexec = QueryExecutionFactory.create(query, model, initialSettings) ;

Tomorrow I'm flying to New York for the rest of the year !
I'll be in New York (actually Brooklyn) from 18 to January 1rst .
In fact I'm here just mainly to see my oldest daughter.
But I would be happy to have contact with Semantic Web people (and rule
engine, and Java).
Another idea is to propose a presentation or a meeting with the EulerGUI
FRAMEWORK (SemWeb + rules + Java), with a User Group , or other meeting
I have a latest presentation where I talk about the whole chain:
http://jmvanel.free.fr/presentations/connaissances_DL_CNL_regles.xhtml
Actually , this latest presentation translated from french by Google is not too bad :
I'll correct that by hand, though .
In fact it could be nice, depending on the public to separate at least 3 topics:
- EulerGUI as a tool for exploring the Semantic Web
- EulerGUI as framework to develop poratable applications centered on an expert system
- controlled English as a way to capture ontologies and rules
<danbri> yup there's a pretty active NYC semweb community
<danbri> look around for Marco Neumann's stuff, he organizes meetups etc

<jmvanel> reading [SWIPL] Using Boehm GC ; Jan's posts are always interesting
<jmvanel> and , by chance it's Nicolas Pelletier, with whom I alreazdy exchanged mails who answers
<jmvanel> it makes me think that it would be fine to use Jan's SWI-Prolog RDF store with Euler engine

COMMIT
- try to fix { true } => ... , but not complete, and anyway this works:
true => ...
- add example examples/exec_system.n3 : launch a system command
- add class SystemExecution to launch a system command from N3
This works:
eg:execution eg:play "/home/jmv/Musique/The Beatles - Help!/13 - The Beatles - Yesterday.mp3" . { eg:execution eg:play ?FILE . } => { ?SystemExecution a java:deductions-runtime-SystemExecution ; javam:execute ( "mplayer" ?FILE ) } .
TODO this crashes :
{ true } => {
java:Runtime javam:getRuntime ?RT .
?RT javam:exec ( "ls" ) .
} .
with stack:
N3Source.parseResult(): parseResult (file:/media/bd003f3b-ff18-4655-91dc-e014ba1af42e/home/jmv/src/eulergui/examples/exec_system.n3) was null ==> re-parse (and possibly re-read N3 source) java.lang.NullPointerException at eulergui.n3model.impl.StatementImpl.toString(StatementImpl.java:158) at eulergui.n3model.impl.FormulaMutableImpl.toString(FormulaMutableImpl.java:57) at eulergui.drools_engine.ParserLink.extractRDFList2(ParserLink.java:314) at eulergui.drools_engine.StatementListHelper.setParserLink(StatementListHelper.java:30) at eulergui.drools_engine.ParserLink.visitAllURI(ParserLink.java:639)
Actually this is not implemented.
For now, better add an ad-hoc class deductions.runtime.SystemExecution , with methods :
void execute( String... arguments); Process getProcess();
<rszeno> try this:
:george :mother :ana . :ana :friend :bob . :george.:mother.:friend :have :hair .
<jmvanel> note that Euler says :
:george :mother :ana. :ana :friend :bob. :friend :have :hair.
<jmvanel> my conclusion ( maybe too quick ) for now is that the dot notation in N3 is not really usable , because not enough defined
I know that Protégé stores its preferences using the Java Preferences API .
To see things more clearly, I ran the code from here :
http://www.vogella.de/articles/JavaPreferences/article.html#preferenceusage
And here is where data ended :
% grep --recursive Europa ~/.java/.userPrefs/ /home/jmv/.java/.userPrefs/_!(@!a!"y!'8!dw"f!'%!dw"h!(k!.g"@!()!~@"m!'`!cg"l!'4!}w"l!&@!~@"z!(@=/prefs.xml: <entry key="Test2" value="Hello Europa"/>
So , we have completely cryptic storage location, OS dependent and in XML .
On the other hand, we have N-Triples, a nice format for objects graphs, such that concatenation of files is possible.
The use case that is not covered by the Java Preferences API is : I want to export my settings on another machine .
This is typical of how computer guys are thinking that they can manage the user data their way. And this time it's not exactly the typical case of the commercial software vendor who tries to lock in its users. It's an Open Source library.
<rszeno> we need to be strong and fight against evil. :)
I had to manually remove the Fact++ jar from plugins/ directory.

COMMIT : better error message ( and app. not blocking ) when opening from command line a file.owl actually containing some N3 .
In Lyon.
The use case is to check each patient record (in batch) for errors. Currently they have a pure Java implementation.
They consider using Drools for the next version.
Using EulerGUI framework allows to directly state rules in ATTEMPTO.
What remains to develop by hand is to populate each patient record in RDF triples, preferably using one of the often used patient record vocabularies (TODO search patient record vocabularies).
Then use one of the examples in EG (TODO link).

Serd is a lightweight C library for RDF syntax which supports reading and writing Turtle and NTriples. Serd is not intended to be a swiss-army knife of RDF syntax, but rather is suited to resource limited or performance critical applications, or situations where a simple reader/writer with minimal dependencies is ideal

<jmvanel> Of course I can reload with more memory , but I need to understand better what TDB does while loading
<jmvanel> apparently it populates a bplustree in memory while loading .
<jmvanel> Does it also happen in normal functionning ?
<jmvanel> I mean for querying ?
<jmvanel> I have to read the doc.
<jmvanel> If it's just a matter of splitting before loading, the tool should do it itself .

Discussion with conan
<conan> jmvanel: did you mean to use insertLogical?
<jmvanel> yes
<conan> this seems like an ugly way to do queries
<jmvanel> I could avoid it for such large files
<jmvanel> once you said that insertLogical is quick as insert ....

<conan> oops
<conan> http://drools.46999.n3.nabble.com/Call-query-from-other-query-td3542082.html
<conan> better
<conan> some relevant links in there
<conan> to my reply to someone asking same hting
<conan> I don't think you need materialised views for your stuff
<conan> so just use ?
<conan> jmvanel: prolog doesn't haev materialised views
<conan> jmvanel: materialised view is turning a query such htat it is effectively a long lived table
<conan> any changes to the underlying ground terms
<conan> is incrementally reflected inthe materialised view results
<jmvanel> ok , thynaks
<conan> if you use ?
<conan> its a lighter wait query
<jmvanel> that is an alternative to queries, but more powerful
<conan> and works like prolog
<conan> materialised views are obviously heavier
<conan> not an alternative
<conan> it's just a normal query
<conan> if you leave off the ?
<conan> it materialises
<jmvanel> reading the mailing list you gave the link ...
<conan> docs are still ab it shallow
<conan> http://docs.jboss.org/drools/release/5.3.0.Final/drools-expert-docs/html/ch05.html#d0e6233
<conan> hmm the formatting looks screwed too
<conan> "As previously mentioned you can use live "open" queries to reactively receive changes over time from the query results, as the underlying data it queries against changes. Notice the "look" rule calls the query without using '?'."
<conan> is in the docs
<conan> we callled it "live open query"
<conan> I'll update it to say materialised views too
* jgraham est parti (Client closed connection)
<jmvanel> so, "live open query" == "materialised views" in newer denomination ?
<conan> yes
<conan> but might go back to using materialised view
<conan> or just use both :)
<conan> jmvanel: if you look at the isContainedIn example
<conan> that shows a traditional prolog transitive closure over a graph
<conan> and it shows it used in two ways
<conan> one normal and one materialised
<conan> jmvanel: tbh I'm not ensure sure what that rule you ahve is doing
<conan> so it finds all Triples and binds to th $SONG to the subject
<conan> so it's finding all song's for the MusicalWork
<conan> oh hang on
<conan> oh hang on
<conan> yes I get what you are doing now
<conan> sotty: he adds the rule
<conan> and the rule inserts all results as an object itself
<conan> he does it logically
<conan> such that when the rule is removed
<conan> the results are removed
<conan> jmvanel: no wonder that was so bad
<conan> jmvanel: your example there could have been done with a simple query
<conan> you never needed a rule
<conan> jmvanel: doesn't even need the new deriviation tree stuff
<conan> jmvanel: http://pastebin.com/9giU1iz4
<conan> that's all you needed
<sotty> yes
<sotty> what worries me
<sotty> is that if he had a rule such as
<sotty> ( X, "type", "MusicalObject" ) ---> ( X, "type", "SomeMoreGeneralEntity" )
<sotty> i.e. a triple inference rule
<sotty> would the performance issues have been the same?
<jmvanel> conan, I knew that a simple query would fit ; this rule I showed you is a remnant of the very begining of the project .
<conan> jmvanel: ok I'm confused
<conan> jmvanel: what's the problem
<jmvanel> I have to test this of course
<conan> why would you not want to use a query?
<conan> inserting stuff like you did with logical insertions for all results
<conan> is going to be painfully heavy
<jmvanel> it's fine with me , using query
<conan> ok
<conan> jmvanel: you should find this order of magnitudes lighter :)
<conan> sotty: no tsure of the issue you mean
<jmvanel> my initial question is this thread was : can I enhance the CPU and mem consumption ?
<conan> no
<conan> jmvanel:just please don't publish stuff showing "how bad drools is" using the example you pasted, compard to a standard prolog query.
<conan> wouldn't be fair
<jmvanel> no, don't worry :) I suspect that using insertLogical take more memory , no ?
<conan> yes
<conan> jmvanel: its a little more efficient in 5.2
<conan> but you are still like tripling the number of objects
<sotty> jmvanel: using drools to do massive triple processing might not be the best of ideas
<conan> because it needs to setup bi-direction and multi-dimensional lists.
<sotty> especially if massive triple processing is the ONLY thing you need to do
<conan> sotty: I believe he's just trying to get his EULER tool to translate to different engines
<conan> sotty: not solve anythign specific
<conan> so it's a "best effort"
<sotty> I see
<conan> sotty: he has his own languaeg and ide, that should be able to target multiple engines for execution
<conan> drools is just one of many
<jmvanel> of course it's not the ONLY thing ; but trying to fix simple case first
<conan> jmvanel: tbh I'm very keen to see how far behind we are other engines
<conan> for triple based stuff
<conan> I'm not expecting ot compete with dedicated triple engines
<conan> but would be interesting to know how far behind we are
<conan> when doing a more apples to apples test
<conan> jmvanel: queries are in general ligher than rules too
<conan> while it's the same rete network
<conan> asl ong s you aren't using materialised views
<conan> we don't bother making a lot of data structures
<conan> we skip all left memory references etc
<jmvanel> "drools is just one of many engines" right, but it's very important for the project , because or stateful nature truth maintenance and Java integration :)
* jvanzyl (~jvanzyl@204.14.239.222) a rejoint #drools
<conan> jmvanel: btw we are looking into improving our TMS
<conan> jmvanel: read the book "building problem solvers"
<jmvanel> no
<conan> jmvanel: good summary here http://www.cis.temple.edu/~ingargio/cis587/readings/tms.html
<conan> jmvanel: anyway prd system TMS is actually only a partial TMS
<conan> jmvanel: it can only do "IN" it can't do "OUT" labelling
<conan> jmvanel: further more sotty wants multi value
<conan> whre IN and OUT become TRUE, FALSE and UNKOWN
<conan> at the moment we can only say TRUE
<conan> but the same si true for all PRD systems
<conan> jmvanel: eventually we'd like to look into be able to do not just JTMS, but also ATMS
<conan> ATMS is much more complex though, due to "multiple worlds"
<conan> jmvanel: but it's interesting stuff
<conan> jmvanel: so you are using drools in a real project?
<conan> http://books.google.co.uk/books/about/Building_problem_solvers.html?id=MraVKw_5g28C&redir_esc=y
<conan> jmvanel: can read a lot of the book from google
<jmvanel> ok
<jmvanel> ATMS == ?
<conan> assumption based truth maintenance system
<jmvanel> ok
<jmvanel> I'll have a look
<conan> jmvanel: all inserted onjects that are not logical justified are called "assumptions"
* ualtin (~ualtin@s15231105.onlinehome-server.info) a rejoint #drools
<conan> jmvanel: a set of assumptions is called an environment or a world
<jmvanel> ok
<conan> jmvanel: ATMS allows you to setup multiple sets of assumptions
<conan> it's sorta like having 1...n ksessions each with an initial different set of assumptions (stated insertions)
<conan> the TMS (logical based and justified insertions) is then shared across those environments/worlds
<conan> jmvanel: the basic idea is you use TMS to help drive your search
<conan> but if you have to keep undoing/reseting your current environemtn
<conan> to try different search paths, it gets expensive
<conan> so why not do those in paralle
<conan> parallel
<conan> jmvanel: http://citeseer.ist.psu.edu/viewdoc/summary?doi=10.1.1.84.2778
<jmvanel> you mean at the app level managing several KB in parallel ?
<conan> jmvanel: this was the sort of thing they built into the CM over at Thinking Machines
<conan> back in te early 90s
<conan> jmvanel: not several KBs
<conan> several ksessions
<conan> jmvanel: imagine you have different data sets, you aren't sure which data gives you the result. you have to in turn create a derivation tree for one configuration of data. then you do it for another configuration
<conan> the peformance would kill
<conan> so TMS is a way to incrementally search through your derivation tree
<conan> ATMS is a way to do that in parallel
<conan> and in a way that one world can learn from the other wrold
<conan> to avoid doing wasted work, subsumption etc
<conan> jmvanel: but, tbh, i'm still learning this stuff
<conan> jmvanel: I don't explain it hat well. a lot of ATMS still escapes me, especially about exactly how to do the directed back trackking.
<jmvanel> anyway , I now have a costumer with a concrete app to develop , a semantic media player
<conan> awesome
<conan> jmvanel: if you are using drools
<conan> jmvanel: don't hesitate to ask for our help
<conan> especially if you can give back performance information and issues
<conan> so we can better focus our efforts
<jmvanel> yeah , Drools in my best option , I hope to manage about 100 000 songs, each with about 10 properties .
<conan> jmvanel: out of interest, why dorols and not say pellet?
<conan> you need reactiveness?
<jmvanel> hopefully in memory
<jmvanel> yes
<conan> jmvanel: what are your plans for high availabilty
<conan> that is something we don't really help with "out of the box"
<conan> there are things you can cook yourself, for redundancy
<conan> and actually it wouldn't be too hard to tweak the engine to make that cleaner
<conan> but depends on ho much time you have and your requirements
<jmvanel> pellet has a bas reputaiton for scalability , and we have 2 ways to reuse OWL ontos as rules
<conan> jmvanel: how much of what you do is under NDA?
<conan> jmvanel: I would suggest you use our latest trait stuff too
<conan> jmvanel: if you can share, atleast privately with davide and I.
<conan> jmvanel: we'll try and direct you
<conan> specially if you could write up the results in a case study
<jmvanel> yeah , you're right I should not sayy too publicly
<jmvanel> too muxh
<sotty> jmvanel : yup, we're trying to build better support to ontologies, in many ways
<conan> jmvanel: ok maybe skype?
<conan> jmvanel: we can setup a skype IM and you davide and I can discuss there.
<jmvanel> anyway the genric parts are and will be in EulerGUI on sf.net
<conan> jmvanel: we are really keen to start getting some real world applicatino of our new Trait/Tiple capabiliity.
<jmvanel> I'm jmvanel1 on skype
<conan> ok sent
<sotty> gtg, I'll be back in 1hr
<conan> sotty: ok
<conan> jmvanel: for instance your triples
<conan> I assume they map to Things?
* sotty est parti ("Ex-Chat")
<conan> jmvanel: lets continue this on IM
<jmvanel> I 've read the article Trait/Triple capabiliity , but my point is that I don't need the OO stuff at all , because the data are semweb data
<jmvanel> ok
<conan> jmvanel: Trait/Triple is for workign with semweb
[19:33:20 CEST] Mark Proctor: so I'm really keen to help you here
[19:33:29 CEST] Mark Proctor: so we can figure out exactly what we can do to improve drools
[19:33:34 CEST] Mark Proctor: for triple based problems
[19:33:52 CEST] Mark Proctor: so looking at data sets, at models and some of the basic query/rules you need
[19:33:54 CEST] Mark Proctor: would really hepl
[19:33:55 CEST] Mark Proctor: hepl
[19:33:57 CEST] Mark Proctor: help
[19:33:59 CEST] Mark Proctor: :)
[19:35:27 CEST] Jean-Marc Vanel: i m here
[19:37:21 CEST] Jean-Marc Vanel: one question I have , when many triples share a same subject string , could Drools store a single instance of the String ?
[19:39:28 CEST] Mark Proctor: good point
[19:39:31 CEST] Mark Proctor: it doesn't now
[19:39:37 CEST] Mark Proctor: but it is something I've thought about
[19:39:45 CEST] Mark Proctor: basically string internalisation
[19:39:51 CEST] Mark Proctor: for large systems, it can make a difference
[19:40:13 CEST] Mark Proctor: tbh, at hte moment hte best way to do this is some interceptor
[19:40:24 CEST] Mark Proctor: you will basically making a hashmap of strings
[19:40:40 CEST] Mark Proctor: and a listener will swap the string for the internalised one
[19:40:46 CEST] Jean-Marc Vanel: some interceptor , OK
[19:40:50 CEST] Mark Proctor: you can either do that your side
[19:40:53 CEST] Mark Proctor: before it goes into the engine
[19:40:58 CEST] Jean-Marc Vanel: :)
[19:41:00 CEST] Mark Proctor: or you can write a working memory listener
[19:41:06 CEST] Mark Proctor: and go to the on insert method
[19:41:09 CEST] Mark Proctor: caste
[19:41:10 CEST] Mark Proctor: and set the field
[19:41:15 CEST] Mark Proctor: as long as the field is the same value
[19:41:22 CEST] Mark Proctor: you won't break the integrity of the engine
[19:41:22 CEST] Jean-Marc Vanel: that's one of the things Prolog engine do
[19:41:47 CEST] Mark Proctor: we could do this for objects created or inserted inside of the engine itself
[19:41:55 CEST] Mark Proctor: but it's hard for objects provided to us
[19:42:02 CEST] Mark Proctor: would be expensive
[19:42:08 CEST] Mark Proctor: as we would have to introspect
[19:42:17 CEST] Mark Proctor: and we don't konw if it's worth it or not
[19:42:19 CEST] Mark Proctor: but thinking about it
[19:42:22 CEST] Mark Proctor: we could do this as a type declaration
[19:42:31 CEST] Mark Proctor: you could declare that some field to be internalised
[19:42:35 CEST] Mark Proctor: as long as it's directed
[19:42:39 CEST] Mark Proctor: we could then handle that ourselves
[19:42:41 CEST] Mark Proctor: good idea
[19:42:53 CEST] Jean-Marc Vanel: anyway the POJO for Drools are suppose to have no side effects if I understoofd well
[19:43:20 CEST] Mark Proctor: so we'd allow some @internalise attribute for a property
[19:43:29 CEST] Mark Proctor: we'd maintain a hashmap of all possible values
[19:43:49 CEST] Mark Proctor: and then on any insert/modify of that object type, make sure we only ever stored the same instance
[19:43:51 CEST] Mark Proctor: I like it :)
[19:43:58 CEST] Mark Proctor: quick to do too
[19:44:04 CEST] Jean-Marc Vanel: sounds good; I sure not the only user that could benefit of this
[19:44:12 CEST] Mark Proctor: no, definitely not
[19:44:16 CEST] Mark Proctor: we can do this for any value type
[19:44:23 CEST] Mark Proctor: that impelments equals/hashcode too
[19:44:26 CEST] Mark Proctor: no it's a great idea
[19:44:27 CEST] Jean-Marc Vanel: I hope to come in London in junuary ;
[19:44:38 CEST] Mark Proctor: I wouldn't want ot internalise all fields by default
[19:44:42 CEST] Mark Proctor: or it would be espensive
[19:44:45 CEST] Mark Proctor: but the user konws their data
[19:44:47 CEST] Jean-Marc Vanel: I could show you what I do with Drools :)
[19:44:49 CEST] Mark Proctor: and they'll konw if the cost is worth it
[19:44:59 CEST] Mark Proctor: I may be in india for january.....
[19:45:11 CEST] Mark Proctor: but hopefully we'll overlap
[19:45:15 CEST] Jean-Marc Vanel: w<hole january
[19:45:17 CEST] Jean-Marc Vanel: ?
[19:45:21 CEST] Mark Proctor: http://www.jboss.org/events/JUDCon/2012/india
[19:45:32 CEST] Mark Proctor: probably last two weeks
[19:46:16 CEST] Jean-Marc Vanel: : January 24-25, 2012
[19:46:31 CEST] Mark Proctor: yes
[19:46:37 CEST] Mark Proctor: so I'll leave around the 20th
[19:46:45 CEST] Jean-Marc Vanel: ok
[19:46:59 CEST] Jean-Marc Vanel: I'll adjust my plans and tell you :)
[19:47:16 CEST] Jean-Marc Vanel: my daughter is in London
[19:50:42 CEST] Mark Proctor: ok
[19:50:53 CEST] Mark Proctor: as i said, i'm very keen to see the type of queries you have and data.
[19:51:00 CEST] Mark Proctor: so if you can show anythign before then, if there is anything public, let me know.
[19:51:15 CEST] Jean-Marc Vanel: ok
[19:51:27 CEST] Mark Proctor: you seen the music example in tinkergraph?
[19:51:38 CEST] Jean-Marc Vanel: tinkergraph? no
[19:51:52 CEST] Mark Proctor: gemlin stuff
[19:52:02 CEST] Mark Proctor: it uses a large music data graph for it's examples
[19:52:08 CEST] Mark Proctor: concerts I think
[19:52:10 CEST] Mark Proctor: let me get it
[19:55:02 CEST] Jean-Marc Vanel: are you thinking of https://github.com/tinkerpop/rexster/wiki/Getting-Started/c4744ab524c447952dad1b122f10e75f6004b8a7
[19:55:05 CEST] Jean-Marc Vanel: ?
[19:55:28 CEST] Mark Proctor: yes
[19:55:45 CEST] Mark Proctor: http://www.slideshare.net/slidarko/gremlin-a-graphbased-programming-language-3876581
[19:55:57 CEST] Mark Proctor: so it uses a large public database for concerts
[19:56:00 CEST] Mark Proctor: to show off their language
[19:56:12 CEST] Mark Proctor: we are looking at how to better support the use cases of gremlin in drools
[19:56:16 CEST] Mark Proctor: like you can do all of that in drools now
[19:56:23 CEST] Mark Proctor: just the syntax is vebrose
[19:56:24 CEST] Mark Proctor: verbose
[19:56:36 CEST] Mark Proctor: so we need to better support graph traversal syntaxes, in a more succinct way.
[19:57:02 CEST] Mark Proctor: maybe do a blueprints implemetnation for drools too
[19:57:04 CEST] Mark Proctor: ok have to go
[19:57:31 CEST] Jean-Marc Vanel: thankls for sharing :)
[19:57:41 CEST] Mark Proctor: slide 40 onwards
[19:57:48 CEST] Mark Proctor: "grateful dead dataset"
[19:57:56 CEST] Jean-Marc Vanel: ok
[19:58:17 CEST] Mark Proctor: I think what gremlin does is an important area
[19:58:22 CEST] Mark Proctor: so we want to do it better
[19:58:30 CEST] Mark Proctor: make it easier for people to get intelligence out of their large datasets
[19:58:39 CEST] Mark Proctor: you can't always structure your data sets
[19:58:42 CEST] Mark Proctor: into nice class models
[19:58:47 CEST] Jean-Marc Vanel: sure
[19:58:48 CEST] Mark Proctor: and graphs are good for that
GREAT NEWS! The EG framework, and its RETE Drools engine will be used for a semantic music player :) .

COMMIT
FIX: N-Triples parser integration:
- fix running Drools engine using button (if there is one (or more) N-Triple in project, the Drools Working Memory is kept)
* introduce field N3SourcetoDrools.allFactSaved and overriden method N3Source.keepsParseResult()
- tested with test/n-triples.n3p

Test project dbpedia-instance_types_fr.nt.n3p with instance_types_fr.nt ; opened in 3mn ( no feedback during loading ).
That's a milestone in the project !!!!!!!!!!!!!!!!!!!!!
org.drools.reteoo.ReteooStatefulSession@5dfc35a6 1 392 525 objets sont actuellement dans la WorkingMemory.
It took 3 mn to load the N-Triples file, and about 1mn to run a simple query :
?SONG a dbpedia-owl:MusicalWork .
The total memory is 2.5 Gb :( .
The result size is 14448 triples .
Using instance_types_fr.nt from dbpedia downloads .
This is not wonderful , but it's the first time that EG is tested with such a large Knowledge Base *in memory* .
<rszeno> you can't make a test only with nxparser to see where it spend so much time?
<jmvanel> Sure, I can with one of the eclipse plugins like TPTP .
<jmvanel> However, I'm rather confident with NxParser ; during loading I suspect the calls to WorkingMemory.insert()
<rszeno> is better to be sure, :)
<rszeno> plus this could help to choose another strategy, to use nxparser in another way
<jmvanel> Yes. In fact I already have a test with triples created by program + Drools
<jmvanel> ( class N3DroolsEngineStressTest )
<rszeno> an example, is adding triples to kb one by one is slower then adding a group of triples, you can use a temporary array, smaller to collet the triples then to push the temp array content to kb
<rszeno> usualy adding is O(n), spliting the size could help
<jmvanel> I don't think so, from what know about Drools
<rszeno> :), as i said, is better to see, :)
<rszeno> if you have good profiling tool could be better
<rszeno> i mean if you can use a good profiler
<rszeno> internals things are always tricky, even for the one who write the code, drools, nxparser authors
<jmvanel> yes , you're right;
<jmvanel> but right now it would be quisker to ask Mark Proctor advices ; he knows enough of what we do with Drools
<jmvanel> quicker
<jmvanel> and he 's present :)
<rszeno> :)
<jmvanel> indeed there are methods like public Future asyncInsert(final Collection collection) {
<jmvanel> ( currently I use plain insert() )
<jmvanel> I also have to ask about possible settings to save memory .
<jmvanel> One thing to check is also if the memory depends strongly on the rules base , which I suspect
<jmvanel> because with class N3DroolsEngineStressTest , 1 000 000 triples and no rule is 500Mb , and with whole EG ( maybe memory lost somehere ? ) and dbpedia file , 1 400 000 triples and a single simple rule == 2.5 Gb , 5 times more .
<jmvanel> lots of stuff to check !
--------------------------
<conan> jmvanel: hi
<jmvanel> I tested a 1400 000 triples from dbPedia , with a single rule; my Triple clas is just 3 Strings , with equals retrun equals on all 3 ;
<jmvanel> It took 3 mn to load the N-Triples file, and about 1mn to run a simple query :
<jmvanel> ?SONG a dbpedia-owl:MusicalWork .
<jmvanel> The total memory is 2.5 Gb :( .
<jmvanel> The result size is 14448 triples .
<jmvanel> it's new tests and some new code, so it's possible that my code is wasting memory ;
<jmvanel> anyway I'd like to know about possible setting to enhance memory and CPU usage ; also would it be quicker to use asyncInsert(final Collection collection) instead of the plain insert() currently

Had a look at http://code.google.com/p/rdfstores/ New directions for RDFStores
Said Zeno:
aho and ulman, theorem: is not posible to build a parser for a chomsky type 0 language
but anothothe theorem say that any chomsky type 0 language can be decompose in 2 chomsky type 2 languages and one isomorphism
that mean we can't build a parser but we can build 2,
on the other hand for any formal system can be in some condition build a production system for each axiom of the fs
that means a grammar for each
since translator is universal, the focus will be on grammars
EG is supposed to be robust enough to handle tiny machines
robust and smart through rules
TODO EulerGUI : provide a feedback when loading an N3 source; when querying with SPARQL

<jmvanel> I get the warning about memory insufficient ,
<jmvanel> but -Xmx is 2g , and using the same OWL donloaded manually , it works !
<jmvanel> strange and looks like a bug :(
musicbrainz.org ==> download database
This is with instance_types_fr.nt, an N-Triples file downloaded from dbPedia here:
http://wiki.dbpedia.org/Downloads37
( look for "Ontology Infobox Types" )
The memory, measured with Ubuntu System Monitor, is, after "networking ..." message, 908Mb, and stays so. 100% of 1 CPU is consumed.
The first query has a 0 triple result:
@prefix dbpedia-owl: <http://dbpedia.org/ontology/> . { ?SONG a dbpedia-owl:SONG ;?p ?v . } => { ?SONG ?p ?v . } .
And the output is :

The second query brings real results, and lasts much longer (already 50 mn at the time of writing, and I let it run ) :
@prefix dbpedia-owl: <http://dbpedia.org/ontology/> . { ?SONG a dbpedia-owl:MusicalWork ;?p ?v . } => { ?SONG ?p ?v . } .
And the output is :

Some remarks:
% wc instance_types_fr.nt 1393530 5574120 202144251 instance_types_fr.nt
First, there a message saying that parsing and KB are deactivated, then jEdit stays a long time with message in bottom: "I/O: one operation in progress" , and 100% CPU consumption :( . Vim is much less greedy ! It only consumes 225Mb and opens in < 1s . EG should choose gvim when the file is large !

<jmvanel> is there a way to trigger some Java code when an object is retracted ?
<jmvanel> the answer to my previous question is in 4.3.5. Event Model :) http://docs.jboss.org/drools/release/5.3.0.Final/drools-expert-docs/html_single/index.html#d0e2003
<conan> jmvanel: we do want a better way to do that, rule based.
<conan> jmvanel: I want to start to expose the life cycle of rules, as listeners
<conan> so when a rule rematches, or unmatches you can execute code
<conan> jmvanel: I might put that into the next 5.4 release.
<conan> jmvanel: will only work for java though, as mvel does not support any type of anonymous block, or functions.

wget --header='Accept: text/n3, application/n3, text/rdf+n3, text/turtle, application/rdf+xml, text/xml, text/plain, text/xhtml, text/html' http://purl.org/ontology/similarity/
The default headers in Jena ( when one does not define a stream by hand ) :
conn.setRequestProperty("accept", "application/rdf+xml, application/xml; q=0.8, text/xml; q=0.7, application/rss+xml; q=0.3, */*; q=0.2");
wget --header='Accept: application/rdf+xml, application/xml; q=0.8, text/xml; q=0.7, application/rss+xml; q=0.3, */*; q=0.2' http://purl.org/ontology/similarity/
After removing the "naked prefixes" in musicontology.n3 , somehow http://purl.org/ontology/similarity/ is still loaded :
loading Anonymous-33 from file:/home/jmv/ontologies/musicontology.n3 Using OWL API version 3.2.3.1824 Rebuilding entity indices... ... rebuilt in 1 ms loading Anonymous-36 from file:/home/jmv/ontologies/musicontology.n3 loading <http://purl.org/vocab/bio/0.1/> from http://purl.org/vocab/bio/0.1/ loading <http://purl.org/NET/c4dm/event.owl> from http://purl.org/NET/c4dm/event.owl loading <http://www.w3.org/2006/time> from http://www.w3.org/2006/time loading <http://purl.org/ontology/ao/core> from http://purl.org/ontology/ao/core loading <http://purl.org/dc/elements/1.1/> from http://purl.org/dc/elements/1.1/ loading <http://purl.org/dc/terms/> from http://purl.org/dc/terms/ loading <http://purl.org/ontology/similarity/> from http://purl.org/ontology/similarity/
And the culprit is :
http://purl.org/ontology/ao/core#
which has this metadata :
ao: a owl:Ontology ; dc:creator <http://tobyinkster.co.uk/#i> , <http://foaf.me/zazi#me> ; dc:date "2010-09-13T13:59:52+01:00"^^xsd:dateTime ; dc:description """The Association Ontology specification provides basic properties for describing specific associations to something, e.g. a context, an occasion, a genre or a mood, and enables furthermore, a mechanism to like/rate and feedback these associations in context to something on/ for the Semantic Web. This document contains a RDF description of the Association Ontology."""@en ; dc:title "The Association Ontology"@en ; owl:imports <http://www.w3.org/2003/06/sw-vocab-status/ns> , sim: , <http://purl.org/stuff/rev> , foaf: , dc: , dcterms: , <http://purl.org/NET/c4dm/event.owl> ; owl:versionInfo 0.4 .
For debugging music ontology, I used EG , which is is not too bad for that , but the killer weapon was a grep in ~/.eulergui/n3_cache/ , preceded by "add refered ontologies" .
------------------------------------------------------------
mainly technical questions about Music Ontology
- status : is it still maintained ? Are you still in charge ?
- the RDF version seems very different from the Turtle one
- problem with http://purl.org/ontology/similarity/ : redirects to an HTML page :
http://kakapo.dcs.qmul.ac.uk/ontology/musim/0.2/musim.html
but apparently for accept-content header == RDF or turtle it keeps the connection alive without producing anything
( the real ontology is at http://kakapo.dcs.qmul.ac.uk/ontology/musim/0.2/musim.n3 , or http://kakapo.dcs.qmul.ac.uk/ontology/musim/0.2/musim.owl )
FRBR : This vocabulary is an expression in RDF of the concepts and relations described in the IFLA report on the Functional Requirements for Bibliographic Records (FRBR).
---------------------------------------------
Opening Music Ontology in RDF with Protégé:
loading ... ... loading <http://purl.org/ontology/similarity/> from http://purl.org/ontology/similarity/ ... org.semanticweb.owlapi.rdf.syntax.RDFParserException: [line=6:column=2] Expecting rdf:RDF element.
Opening http://purl.org/ontology/similarity/ with Protégé:
the message ( after maybe 1 hour ) is :
org.semanticweb.owlapi.rdf.syntax.RDFParserException: [line=6:column=2] Expecting rdf:RDF element.
TODO
-Dsun.net.client.defaultConnectTimeout=3000 -Dsun.net.client.defaultReadTimeout=3000
Trying with Protégé:
Music Ontology imports this , and we get into trouble :
http://purl.org/ontology/similarity/
redirects to an HTML page (HTML no matter what the accept-content header says) :
http://kakapo.dcs.qmul.ac.uk/ontology/musim/0.2/musim.html
and the trouble is that the reading freezes forever . And it's the same with EulerGUI when called in command line:
eg --pass http://purl.org/ontology/similarity/
However , when adding the URI with the button, EG says in a popup :
Could not load N3 source from URL http://purl.org/ontology/similarity/ N3SourceFromXML_Gloze.extractXMLNamespaces(): Could not load from URL http://purl.org/ontology/similarity/ reason: Read timed out cause: null Cause: java.net.SocketTimeoutException: Read timed out

<jmvanel> are there some figures or rough ideas of the ratio size(WM) / size(asserted objects) ?
<jmvanel> i guess it can depend widely of the rules
<jmvanel> Hi any idea of a plotter or statistical analysis tool that can be plugged to RDF, N3 or SPARQL data sources ?

Opened with EulerGUI, this takes 1.7Gb ! :( .
I opened the Kea directory with eclipse, the .project
etc are
here. From there , I ran the tests in TestKea.java. It says :

Looking for french texts in NLTK :
~/nltk_data/corpora/ % grep --recursive -l économie . europarl_raw/french/ep-00-02-16.fr europarl_raw/french/ep-00-02-03.fr europarl_raw/french/ep-00-01-17.fr europarl_raw/french/ep-00-01-18.fr europarl_raw/french/ep-00-02-15.fr europarl_raw/french/ep-00-02-02.fr europarl_raw/french/ep-00-01-19.fr europarl_raw/french/ep-00-01-20.fr europarl_raw/french/ep-00-02-14.fr
I found a suitable thesaurus from http://www.archivesdefrance.culture.gouv.fr/thesaurus/page/Matiere ( click on Téléchargement ).
I'll try to use Kea on these french texts in NLTK.
After reading in Kea readme file the paragrah 2. Getting started / Building a keyphrase extraction model , I tried this :
./run.sh kea.main.KEAModelBuilder -l ~/nltk_data/corpora/europarl_raw/french/ \ -m europarl -i fr \ -v archivesdefrance.culture.gouv.fr_thesaurus_Matiere -f skos
where run.sh is :
for f in lib/*.jar do cp=$cp:$f done echo java -cp $cp $* java -cp $cp $*
In fact, Kea accepts only files with .txt suffix, so I do this :
cd ~/nltk_data/corpora/europarl_raw/french/ for f in *.fr do textfile=`basename $f .fr`.txt ln -s $f $textfile done
The first run is not the right one:

COMMIT in EulerGUI
- Drools N3 engine:
* Integrity Constraint were broken
* FIX crash with rdf:nil rdf:rest ?X . ( occurs in Jos' OWL rules )
- give names to threads in SPARQLServiceInputAction
- clean code in ParserDataIO
COMMIT in Déductions
SWRL --> N3 translator: a literal in consequent was treated as a variable; tested with :
a1(?x), c1(?y), r1(?x, ?y) -> dp1(?x, 10)
added project test_swrl_to_n3.n3p to run the SWRL to N3 translator manually
thanks to Pascal van Hille for the example
cwm --rdf swrl_rule_owl.owl --n3==dilpqst
I found an error in Protégé's Turtle parser ( P 4.2.0 build 249). The error message is :

The cause is using a prefix with no suffix. Indeed changing

FIX : N3 Drools engine:
- Fix test cases in math.n3 involving a Number in object position in consequent
- fix e:findall when antecedent is a blank node
- does fix examples/acceleration.n3p
- no more tests deactivated in TestReasonning
Fix this test case in math.n3 :
:Everest:height 8848 ; :name "Everest" . :Mont_blanc:height 4800 . :McKinley:height 6194 . :Mauna_Kea:height 4205 . { _:d e:findall ( ?H { ?M :height ?H } ?LIST ). ?LIST e:max ?MAX . # ?MAX log:equalTo 8848 . # TODO : Drools : output is 8848.0 } => { :test :pass_max true . :test :res ?MAX . } .

I coined the expression "Semantic Software Engineering".
At the first level, this means : writing configuration files in N3 instead instead of XML, Java properties, JSON, or ad-hoc formats.
Over the years, the RDF community has developped a bunch of tools to translate back and forth between RDF and other formats. But there is little available for software engineering data. This data includes, but not limited: SQL schemas and queries, Hibernate and other ORM, Spring and other injection frameworks configuration, Maven and other build tools, firewall configuration, web server (Tomcat, Apache , .. ), eclipse, OsGi, and other plugin architectures. ...
Why SSE ?
How to do?
Of course , I'm aware that semantics of software configuration items is often complex, with a narrow meaning related to one piece of software. There is no silver bullet, but much stuff can be reused with minimal inference.
At a higher level, "Semantic Software Engineering" can mean also express declarative objects closer to programming in N3. The most obvious domain is Graphical User Interface. Indeed the semantics brought by Swing, GWT, HTML, Flew, and others are close. For one thing because they borrowed from an older system: TCL/Tk .

I discovered that externalPom() and libraryDependencies are *not* working together; alas mharrah said on SBT list
http://groups.google.com/group/simple-build-tool/browse_thread/thread/d7944762322b4362
I found a nice code sample by a Korean guy to translate a pom.xml into SBT style of dependencies.
https://gist.github.com/388334
But it does not do the transitive (recursive) dependencies.
object mavenToSBT extends Application { val xml = <dependencies> <dependency> <groupId>org.scalanlp</groupId> <artifactId>scalala_${scala.version}</artifactId> <version>0.3.1</version> </dependency> // .... val data: Seq[(String, String, String)] = (xml \ "dependency") map { d => val groupId = d \ "groupId" text val artifactId = d \ "artifactId" text val versionNum = d \ "version" text (groupId, artifactId, versionNum) } val CrossBuildArtifact = """([\w-]+)_\$SCALA_VERSION\$""".r def dep(a: String, g: String, v: String, cross: Boolean) = { val sep = if (cross) "%%" else "%" val ident = a.split("-").map(_.capitalize).mkString """val %s = "%s" %s "%s" %% "%s" """ format (ident, g, sep, a, v) } val m = data map { case (g, CrossBuildArtifact(a), v) => dep(a, g, v, true) case (g, a, v) => dep(a, g, v, false) } mkString("\n") println(m) } |
and , since externalPom() is not managing transitive dependencies, I'm trying to use my POM translated in Ivy ...
http://stefan222devel.blogspot.com/2010/01/how-to-convert-maven-pomxml-into-ivy.html
ant -f pom_to_ivy.ant.xml convert
and , now yet another issue : the sbt run in waiting forever ; it is not consuming CPU :(
I could try the STB from source code , as ArmyOfBruce advised
I got it "working" , but with Ivy the transitive dependencies are *not* managed either
Is there a utility to generate a pom with transitive dependencies included ?
Scala: using mavenToSBT.scala to translate the pom dependencies into stb format,
and putting this into built.sbt
plus added manually indirect dependencies ==> it compiles !!!

<jmvanel> ArmyOfBruce, this works (I forgot alias in front ) :
<jmvanel> alias sbt='java -Xms1600m -XX:MaxPermSize=512M -XX:+CMSClassUnloadingEnabled -jar ~/src/read-write-web/sbt-launch-0.11.0.jar'
<jmvanel> and for my other trouble with Maven project, I'll try to give directly to stb the big classpath obtained from mvn dependency:build-classpath
<ArmyOfBruce> I've needed -Xss2M for sbt 0.11 to work for me.
<ArmyOfBruce> and at times, have appeared to need -XX:ReservedCodeCacheSize=256M
<ArmyOfBruce> jmvanel: if you have a big codebase, you may run into what I did with memory usage (which is fixed in current snapshots)
<jmvanel> the [success] was for goal compile ; now goal progard has trouble , but it first DID packaging into launcher-0.11.1-SNAPSHOT.jar ;
<jmvanel> but after when Reading library jar [/home/jmv/apps/jdk1.7.0/jre/lib/rt.jar , it complained :

<jmvanel> but maybe what progard does is not indispensable

Hi externalPom() does not seem to add *recursive* dependencies to the classpath
<jmvanel> known bug ?
<jmvanel> mharrah, ping; I noticed similar bug 59 ; can it be that this extra feature is missing ?
externalPom() doesn't set classpaths correctly
https://github.com/harrah/xsbt/issues/59
http://macstrac.blogspot.com/2009/04/scala-as-long-term-replacement-for.html
Scala seems to hit the perfect sweet spot between the consise feel of a dynamic language, while actually being completely statically typed.
Another one :
The thing which most impresses me is the core language syntax is pretty small and simple (the spec is about a quarter the size of Java's); but its way more powerful and flexible and is very easy to extend in libraries to add new semantics and features. For example see the Scala Actors. So its ideal for creating either embedded DSLs or external DSLs. There's really no need to have Java , XPath, XSLT, XQuery, JSP, JSTL, EL and SQL - you can just use Scala with some DSLs here and there (examples of this later...).
Along this line of thought, why nobody ever did an N3 DSL in Scala ?

interesting dialog on swig IRC
<tktiddle> So ive found that python rdflib allows you to store triples in a mysql database, whats the difference between doing this and using a "triple store" like 4store?
* swh est parti (Quit: swh)
<mischat> 4store uses its own backend, it holds everything in RAM
<mischat> not all triple stores do that, so it depends on the triplestore you are using i guess
* mischat note that I work on 4store, disclosure and all
<mischat> and yeah, so quite a few of the triplestore implementation store the triples to a SQL backed relational database
<shellac> tktiddle: rdf-specific stores have certain advantages over relational databases. they act in ways that are a bit alien to typical relational databases (e.g. value comparisons, self-joins)
<timbl> Lots of stuff happening in read-write linked data -- with data.fm and read-write-web projects both getting more solid
* egonw (~egonw@m77-219-198-199.cust.tele2.se) a rejoint #swig
<mischat> this is the new community project right, /me hasn't been following it at all, i guess i should
* mhausenblas (~mhausenbl@wlan-nat.fwgal01.deri.ie) a rejoint #swig
<timbl> data.fm was started by Joe Presbrey, read-write-web by Alexandre Bertails.
<mischat> is this where the work is taking place : http://www.w3.org/community/rww/ ?
* mischat recalls data.fm
<mischat> joe implemented the webid stuff very early on iirc
<timbl> Yes, python.
<timbl> Alex looked at getting a supported implementation running in W3C space, and ed=nded up writing one in Scala based on Jena and unfiltered.
* egonw_ (~egonw@109.58.90.82.bredband.tre.se) a rejoint #swig
<mischat> ms8 at stanford has implemented ACLs for 4store, which is pretty neat, i wonder whether he has thought about supporting webid's for identity
* ldodds (~ldodds@212.36.55.94) a rejoint #swig
<mischat> so that you can have a given identity the ability to update/query a collection of graphs in the sparql-store
* egonw est parti (Read error: Connection reset by peer)
* chimezie est parti (Quit: chimezie)
<timbl> The read-write-web model is that a graph corresponds to a (virtual) web document which is the granularity of access control

Good morning
I'm looking for testers for EulerGUI 1.9 beta: Semantic Web + N3/Turtle syntax GUI and framework:
SemWeb explorer( download, visualize and navigate through ontologies ), rules engines, mixing business rules and Java
Features (Fact Sheet) : http://eulergui.svn.sourceforge.net/viewvc/eulergui/trunk/eulergui/html/documentation.html#Features
join us at #eulergui .
Currently this does work; generated Drools is OK, LocalAction is not abstract anymore, and ProjectGUI constructor does not start internal KB (ApplicationKB) anymore.
{ ?P a java:n3_project-ProjectGUI . } => { _:d eg:trace ( "addInToolbarAndMenu" ?P ). ?P javap:sourceFilesManagement ?SFM . _:ACTION a java:n3_project-LocalAction . _:ACTION javam:setProperties ( _:ACTION "bla" "internet.png" "bla bli" "" ) . ?SFM javam:addInToolbarAndMenu ( _:ACTION ) . }. |
HowTo :
Just paste the above rule in in the preference file ( from menu File / preferences ).
Works too ( no parentheses ) :
{ ?P a java:n3_project-ProjectGUI . } => { _:d eg:trace ( "addInToolbarAndMenu" ?P ). ?P javap:sourceFilesManagement ?SFM . _:ACTION a java:n3_project-LocalAction . _:ACTION javam:setProperties ( _:ACTION "bla" "internet.png" "bla bli" "" ) . ?SFM javam:addInToolbarAndMenu _:ACTION . }. |
Does not work with question mark variables and parenthesis :
Grave: Drools Error in file:/home/jmv/.eulergui/preferences.n3 , Error: Rule Compilation error $SFM cannot be resolved
FIXED on oct 19

Such expressions in LHS do not compile anymore :
C( f == "a" || f == "b" )
==> compiler says : Predicate ' f == "a" || f == "b" ' must be a Boolean expression
Note that this does not work any more :
C( ( f == "a" ) || ( f == "b" ) )
Run this code :
https://eulergui.svn.sourceforge.net/svnroot/eulergui/trunk/eulergui/src/test/java/samples/DroolsSample.java
and look at tripleTestDisjunction(), tripleTestDisjunction2()
with this library :

<jmvanel> I finally found a case that fails with Drools 5.4.0-SNAPSHOT:

<jmvanel> look at testEval()
rm -r /home/jmv/.m2/repository/org/drools/*/5.4.0-SNAPSHOT
rm -r /home/jmv/.m2/repository/org/mvel/mvel2/*

REGRESSIONS:
- re-activating the main query with the checkbox does not work
- sometimes the inference buttons are not activated when the N3 sources pre-processing is finished
- changing project from File menu closes the application
- FuXi should be deactivated
Asked on Drools IRC:
I populate a working memory while the rule base is empty; then I populate the rule base ; then I fire rules ==> just one rule actually fired.
Is this normal ? ( using 5.4.0-SNAPSHOT )

J'ai bossé sous Eclipse Helios avec Scala 2.9.1, sans Maven ni SBT ...

J'ai trouvé le compilo d'Eclipse moyen sur un projet mixte, je devais systématiquement faire un clean du projet sinon j'avais des erreurs de compilation loufoques.
Une fois tous les fichiers sources au format scala, j'ai progressivement retiré les dépendances vers les bilbiothèques java, en particulier les collections, et commencé à "scalaiser" certaines parties du code.

COMMIT
- Add call to Namespaces.declareImportantPrefixes() in OpenPreferencesAction.java .
- make methods public to enable N3 Java triples to access it :
ProjectGUI.getSourceFilesManagement()
SourceFilesManagement.addInToolbarAndMenu()
I try to add features in EG through the preferences.n3 file; conceptually this is a combination of Spring framework configuration and eclipse extension points .
I think of adding an ACE import in EG ; this would be added by the preferences file .
Currently this does not work in EulerGUI :
java:eulergui-EulerGUI javam:instance _:instance .
EulerGUI.instance ()
is a (singleton) method without argument
that returns an EulerGUI object.
It does not fit well with the current Java-N3 mapping , where this would be
interpreted as the call to method instance with one argument bound to name
instance
in the KB .
I could add this feature : at runtime, when the object in a Java N3 triple is not bound, it is interpreted as a new binding to the return value of the method corresponding to the N3 predicate.
Currently this does not work, Drools says: $SFM cannot be
resolved
{ ?P a java:n3_project-ProjectGUI . } => { ?P javap:sourceFilesManagement ?SFM . ?ACTION a java:n3_project-LocalAction . ?ACTION javam:setProperties ( ?ACTION "bla" "icon1" "bla bli" "" ) . ?SFM javam:addInToolbarAndMenu ?ACTION . }. |
because this is generated:
DeferredPropertyAssignment dpa_P2 = new DeferredPropertyAssignment();
dpa_P2.setSubject($P.toString() );
dpa_P2.setPredicate( "<http://java.sun.com/predicate#sourceFilesManagement>" );
dpa_P2.setObject($SFM.toString() );
insert( dpa_P2 );

<rszeno> :)
<jmvanel> when it's finished the inference buttons are activated
<jmvanel> after all the N3 source buttons are activated ;
<jmvanel> so what happens is visible :)
Working with threads like I do forces me to read my code and make it more robust ; it's like exercise that make a person more robust .
In N3ConversionRefesher.doN3SourceAdded() , a new thread is started for each N3Source, to process each ones in parallel. It's even better on multi-core machines, but even on single core, the download from Internet can occur in parallel.

<jmvanel> BTW uploaded a snapshot yesterday , so that you can load http://graph.facebook.com/jmvanel into EG :)
I'm having fun with N3 rules triggering Java actions; look at examples/BloodPressure.n3p . This works nicely :
{ ?L :alert "true" ; log:uri ?LL . } => { ?F a java:javax-swing-JFrame ; javap:title ?LL ; javam:setSize ( 200 200 ) ; javap:visible true . }. |
However from a software engineering point of view, this is mixing too much N3 and Java. On the right handside, one has to know too much of Java. And EulerGUI does not have the facilities of eclipse for Java code completion.
For EulerGUI framework, the recommended practice is to encapsulate the Java action in a class . Then this class itself will be encapulated in a pure N3 action:
{ ?L :alert "true" ; log:uri ?LL . } => { :application :displayAlert ?LL . }. { :application :displayAlert ?LL . } => { ?F a java:eulergui-gui-TemporaryFrame ; javap:localizedMessage ?LL . }. |
In this article, I showed how one can add features to the current project, which becomes thus a kind of application.
In a next article, I'll show how one can add features to EulerGUI itself, expressed by rules, Java classes, or a mixture of both.
The snapshots are here :

How do I add scala-compiler.jar to my eclipse project ?
Hi Dave
I'm learning Scala, and I develop an IDE called EulerGUI about rules
and Semantic Web that uses Drools.
These are good reasons to get interested in rooscaloo (and I like your
blog too ).
I guess the Scala language has slightly changed since you made
rooscaloo (what wezre the version at the time ? ).
I had to add imports in a few classes (I can send a patch ).
But now I'm blocked, because I don't know a good way to satisfy this
import with eclipse :
import scala.tools.nsc.InterpreterResults._

I found the howto for Maven + Scala here http://stuq.nl/weblog/2008-11-26/4-steps-to-add-scala-to-your-maven-java-projects
( the plugin site itself is outdated and incomplete :
http://scala-tools.org/mvnsites/maven-scala-plugin/ )
Are there migration tools / translation (possibly partial translation ) to Java (or other) to Scala?
http://scala-tools.org/mvnsites/maven-scala-plugin/usage.html
From ScalaByExample.pdf :
Using averageDamp, we can reformulate the square root function as follows.
def sqrt(x: Double) = fixedPoint(averageDamp(y => x/y))(1.0)
This expresses the elements of the algorithm as clearly as possible.
For Drools bug report:

mvn versions:display-plugin-updates says:

BUT maven-surefire-plugin is at version>2.8.1 ( not 2.9 )
Is this a know problem ?
<rszeno> imagine something based on the same principle where exploring, inference and everything else can start from a data set specified by user, a url for example
<rszeno> a static interface doesn't fit in this landscape
<rszeno> i would split this in two subsystem, one for ajusting the interface and another for navigation
<rszeno> navigation like in pelorus
<rszeno> this involve a classification mechanism
<rszeno> something similar would be nice for Flora
<jmvanel> sorry , don't understand http://nasa.clarkparsia.com/
<rszeno> you didn't open the link?
<jmvanel> yes
<rszeno> and?
<rszeno> did you click on Saturn 1B for example?
<rszeno> or better, Saturn 5
<rszeno> in the first list box
<jmvanel> i just did
<jmvanel> noithing shows that it's clickable :(
<rszeno> now select something from the second list box
<jmvanel> i did
<rszeno> at each selection, it add data to the next listbox
<rszeno> under each listbox are some operators, and, or not,
<jmvanel> but how do I interporet that in terls of RDF ?
<rszeno> are enabled only after selection
<jmvanel> interpret
<rszeno> each listbox represent a property of a class
<rszeno> or a class in this case
<rszeno> the connection with next listbox is based on the relation
<rszeno> Launch is a property of Lounch Vehicle
<rszeno> building a general, non specific interface, will start from ontologies involved
<rszeno> http://www.thefreelibrary.com/The+Role+of+Classification+in+Knowledge+Representation+and...-a057046525
<rszeno> there is a section for facet

<jmvanel> that for the guided tour
<jmvanel> thanks for the guided tour
<rszeno> :)
<rszeno> you are welcome
<jmvanel> I'll see the other link later; now I struggle with the test suite ;
<rszeno> probably is complicate to build such a thing, :)
a matter of costs

Now I have a tedious programming task : I have a stack of depth 4 , were I pass a Project argument , and I should now pass a list , because of the N3 project format :
Thread [main] (Suspended) ProjectFactory.restoreN3P(URI) line: 271 ProjectFactory.restoreAny(URI, boolean) line: 371 CommandLineArguments.makeProjectFromUserArgument(String[]) line: 44 ProjectGUI.main(String[]) line: 195 |
Thread [AWT-EventQueue-0] (Suspended) ApplicationKB.recoverProjectObjectFromKB(URL, URI) line: 469 ApplicationKB.loadN3Project(URI) line: 457 ProjectFactory.restoreN3P(URI) line: 270 ProjectFactory.restoreAny(URI, boolean) line: 371 ProjectFileManagement$OpenProjectAction.actionPerformed(ActionEvent) line: 529 JMenu$1(AbstractButton).fireActionPerformed(ActionEvent) line: 1995ventDispatchThread.run() line: 122 |
When reading an N3 project file , a new (empty) project with URI made after the project file (ending in .n3). But the project contained in the file is ignored.
<file:/home/jmv/src/eulergui_new/euler_project.xml.n3p.n3>
Question asked on #java without answer :
I use a library class writing on a OutputStream or Writer; I want to interpose a string replacement on lines, before writing to a file;
so I need a class that will buffer all output up to an end of line, and call a user method to transform it
library class --> ForwardingOutputStream --> CorrectorBufferedInputStream --> FileOuputStream
webmarker link
the spec gives the translation of OWL RL in a neutral rule language : http://www.w3.org/TR/owl2-profiles/#Reasoning_in_OWL_2_RL_and_RDF_Graphs_using_Rules
Degugging : saving the N3 project file:
uriForSubject (java.lang.String) <file:/home/jmv/src/eulergui_new/euler_project.xml.n3p> triple.getSubject() (java.lang.String) <file:///home/jmv/src/eulergui_new/euler_project.xml.n3p> |
It's NOT caused by URLHelper.normalizeURL() : just 1 reference in addN3SourceToEulerArguments()
Here is NOT the root cause :
Thread [doN3SourceAdded: file:/tmp/eg-3944119603762958536.n3] (Suspended (breakpoint at line 45 in Triple)) LineTrackingTriple(Triple).<init>(String, String, String) line: 45 LineTrackingTriple.<init>(String, LinesAndCols, String, LinesAndCols, String, LinesAndCols, LinesAndCols) line: 33 DroolsTripleHandler.acceptTriple(String, LinesAndCols, String, LinesAndCols, String, LinesAndCols, String, LinesAndCols) line: 174 ParserLink.visitAllURI(LineTrackingTripleHandler) line: 629 N3SourcetoDrools.translate(IRDFIterator, String, boolean, boolean, boolean) line: 285 N3SourcetoDrools.translate(N3Source, boolean, boolean, boolean) line: 257 N3DroolsEngineFacade.translate(N3Source, boolean, boolean, boolean) line: 91 Project.translateToDrools(N3Source, boolean, boolean) line: 973 N3ConversionRefesher.updateKB(Project, N3Source) line: 161 UpdateN3Thread.run() line: 41 |
This is the root cause :
model.getWriter( "N3" ).write( model, tmpOutputStream, null);
Jena 's writer transforms <file:/XXX into <file:///XXX .

About "discover capabilities" , do you want to try what already exists ? Type
eg --pass http://jmvanel.free.fr/hypervert/images_le_clos/vue_est.rdf
Now click on Tools -> add referred ontologies.
These "referred ontologies" (coming from prefix declarations) are added to the project, in an deactivated state. You can then open them in the N3 editor just like any N3 source.
Now click on Tools -> launch OWL reasoner.
You get multiple new windows docked, each showing a tree of OWL classes. There is one frame per N3 source , if it really has ontology information; and the frame titles indicate the N3 source.
Now open the FOAF frame; type Person in the upper field ; it filters the tree to show only classes having this string.
This filtering feature is useful to explore large ontologies. I reckon that Protégé has much the same features, but Protégé does not have the filtered tree.
An even smarter way of getting started, when you only have the name of an ontology is this. Suppose you heard about FOAF (actually the most well-know ontology) , but you don't know where it is .
You just write in the editor :
foaf:bla :x :x .
then save. EulerGUI , leveraging on prefix.cc , will add missing prefix declaration;
then you can do Tools -> add referred ontologies like above (and remove
the dummy triple foaf:bla :x :x.
) .
It works in the editor, and in the N3 shell too.
I completed RDF image annotation of the view towards east of the arboretum , with the nice Kanzaki tool : http://jmvanel.free.fr/hypervert/images_le_clos/vue_est.rdf
Technically it is interesting as an example of RDF usage . The RDF is used by an XSLT transform that generates the image map..

<rszeno> lynx -dump -display-charset=utf-8 URL > textfile
<rszeno> is a excellent way to get pages as text
<rszeno> http://www.deepspace6.net/projects/netcat6.html
<rszeno> this is the tool but there is no docs on site
<rszeno> is package in debian anyway
<rszeno> http://linux.die.net/man/1/nc6
<rszeno> look to the "File transfer" section
<jmvanel> i heard about nc, it's a swiss knife with network stuff
<jmvanel> While checking my garden inventory , I found this nice page in RDf with an XSLT style :
<jmvanel> alas, the XSLT is not generic
<jmvanel> maybe some rules would add intelligence to the display ?
I try the URI with eg --pass , but there is a stupid bug :
Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: URI has a query component at java.io.File.<init>(File.java:372) at n3_project.ProjectGUI.setLastFile(ProjectGUI.java:814) at n3_project.ProjectGUI.<init>(ProjectGUI.java:181) at n3_project.ProjectGUI.newWindow(ProjectGUI.java:245) at n3_project.ProjectGUI$1.run(ProjectGUI.java:205) |

Why use the semantic Web technologies ? Answer : to enable Linking of Open Data, in both ways: enable other sites to link to our data, and agregate data from elsewhere .
How to make a naturalist's observations site? Answer: to store all data in a SPARQL 1.1 server; use as much as possible standards vocabularies ( FOAF, Dublin Core, etc); for consultation, generate SPARQL queries from forms , generate HTML from N3 responses; for entering data generate forms from special OWL classes dedicated to represent input; it would be good to have AJAR ( Asynchronous JavaScript with RDF ) to validate inputs and other tasks.

DESIGN NOTE: there is a duplication of information, for historical reasons :
Combine open internal KB in editor, open project from N3 , OpenPreferencesAction, save project in N3 ?
Need to watch modification of N3 file file created in LaunchApplicationKBN3Editor "open internal KB in editor" ; similar to watching of user preference file in OpenPreferencesAction;
but fileSnapshot in class LaunchApplicationKBN3Editor is not updated with the KB; could use Drools mechanism to do that.

Refactoring : moving a field to a delegate class : is it possible ?
I have a a field f , several methods using f, says m1 and m2, and another field deleg of type C1 . I'd like to move together f, m1 , m2 to class C1 .

- do not check timestamp of N3 source web location when the current timestamp is too recent, e.g. 500 ms.
- error highlighting and caret placement in editor broken
- run SPARQL in a thread
- before running SPARQL, the left button should be grey, and after running be activated (same for translations from other non N3 sources)
- new example ckan_explore.n3p should also show metadata about the data sources discovered
- SPARQL endpoints should have a tooltip with a short description
- new endpoints found in EG project should be added in the combo box
what are the properties used in data source directories for SPARQL endpoints ? For example in http://semantic.ckan.net/sparql/ it is http://rdfs.org/ns/void#sparqlEndpoint
- new endpoint added by user should be added in the combo box
- http://semantic.ckan.net/sparql/ should be added in the combo box
- RDFToN3Converter : stream were not closed :( TODO : check closing in other places
- TODO: have to fix the GUI's list management in EulerGUI singleton (cf Revision 2576)
- REGRESSION FIXED: adding a new SPARQL query to a project ( cause: field uri_ in N3SourceFromSPARQLSource was not set ) TODO: probably a more general fix is to fix N3Source.setProject(Project) , so that fileds uri_ , location and project are in sync (cf Revision 2566)
- TODO bad behavior on GUI events in deductions/n3_nojs/person-app.n3p
DONE
removed these useless declarations ( and changed the defaults in eclipse compiler ) :
private static final long serialVersionUID = 1L;
Idea for a non -trivial and useful graph transform : N3 <==> SPARQL
for N3 ==> SPARQL : reify N3 rules ; add FILTER and other SPARQL stuff, generate SPARQL string
COMMIT
now N3 URI sources are added in a thread ! GUI much more reactive !
e.g. when loading http://purl.org/dc/terms/ , you see first the button for DC terms , then 1 sec after you see the button for the rules in it

EulerGUI ideas TODO :
ProjectSessionManagement.newN3SourceName()
COMMIT:
ProjectGUI :
- if no context ( project or file opened before ) use user.dir ( startup dir ) for file choosers
- if given file for lastFile is a temporary file , or in the eulergui cache , do not change lastFile
- prefixes beginning with / like http://purl.org/dc/terms/ , gave a bad name for associated rules : /tmp/.as.rules.n3
- use get/set lastFile in most places

Tried to get N3 out of ckan, but it only speaks JSON :( :
wget –header="Content-Type: application/n3" http://ckan.net/api/rest/package
EulerGUI TODO : bug : changing endpoint URI and saving project : EG is blocked, and moreover the .n3p is empty !!!
EulerGUI idea (TODO?): add a new EG engine that starts "eye" by a system call like FuXi and CWM ; this would be OK for Jos
<rszeno> lcpvrr1 try 'select distinct ?l where { [] rdfs:label
?l . }
'
<rszeno> for 15 labels i would not use dbpedia, :)
<jmvanel_> back ; now 28°
<rszeno> ?s rdfs:label ?l will ask for a cartezian product, that means will search for 'number of ?s' * 'number of ?l' but [] will tell virtuoso to ignore ?s wich mean a size of 'number of ?l'
<rszeno> that is first reason
<rszeno> second, passing all results over the net, duplicates is slow, so let virtuoso to remove duplicates using distinct
<jmvanel_> should add this in EG manual
Looking in CKAN things, we find information here : http://wiki.ckan.net/RDF_and_CKAN ( CKAN is not natively RDF ). From this we intuited the CKAN SPARQL Endpoint: http://semantic.ckan.net/sparql/ .
It is using mainly the VOID vocabulary ( Vocabulary of Interlinked Datasets) : http://vocab.deri.ie/void .
The quite generic steps for exploring a data source are :
1. Getting the properties and classes used
find_properties.sparql
SELECT DISTINCT ?p WHERE {?s ?p ?o}
find_classes.sparql
SELECT DISTINCT ?Concept WHERE {?x a ?Concept}
2. Looking at values of the most interesting property
By asking all properties, I discovered that the property for sparql Endpoint is http://rdfs.org/ns/void#sparqlEndpoint ; not http://vocab.deri.ie/void#sparqlEndpoint as indicated in the doc.
# NOTE : http://vocab.deri.ie/void#sparqlEndpoint does not exist in CKAN data !! CONSTRUCT { ?D <http://rdfs.org/ns/void#sparqlEndpoint> ?EP. } WHERE { ?D <http://rdfs.org/ns/void#sparqlEndpoint> ?EP. } |
3. Focusing on an interesting URI
Looking for "ecology" in previous result, there is one SPARQL database : <http://ckan.net/package/linked-open-data-of-ecology>
So the apropriate query is :
CONSTRUCT { <http://ckan.net/package/linked-open-data-of-ecology> ?P ?O . } WHERE { <http://ckan.net/package/linked-open-data-of-ecology> ?P ?O . } |
whose result is ( abridged ) :
<http://ckan.net/package/linked-open-data-of-ecology> <http://purl.org/dc/terms/description> """<p>Linked Open Data of Ecology (<a href=\"http://ecowlim.tfri.gov.tw/lode\">LODE</a>) is a prototype to integrate the data of ecology by linked data approach. So far the subjects include most of <a href=\"http://ecowlim.tfri.gov.tw/lode/resource/firedb/ForestFireEvent\">wildfire</a>, <a href=\"http://ecowlim.tfri.gov.tw/lode/page/taibnet/Species\">taxonomy</a>, biodiversity data of <a href=\"http://ecowlim.tfri.gov.tw/lode/page/taif/Species\">plants</a> and <a href=\"http://ecowlim.tfri.gov.tw/lode/page/flyhorse/Species\">insects</a> in Taiwan. </p> <p>2011/07/20: Recently we added a new dataset about measurements of DBH(diameters breast height) of tree entities in Nansi forest dynamics plot (<a href=\"http://ecowlim.tfri.gov.tw/lode/resource/fdp/NansiForestDynamicsPlotCensus/01\">FDP-NS</a>). </p>""" ; <http://purl.org/dc/terms/isPartOf> <http://ckan.net/group/lodcloud> ; <http://purl.org/dc/terms/title> "Linked Open Data of Ecology" ; <http://rdfs.org/ns/void#exampleResource> <http://ecowlim.tfri.gov.tw/lode/data/taibnet/Species/Callyodon_laxtoni?output=xml> , <http://ecowlim.tfri.gov.tw/lode/data/firedb/ForestFireEvent/1065?output=xml> , <http://ecowlim.tfri.gov.tw/lode/data/taif/Specimen/TAIF-PLANT-1-1-10026-187900?output=n3> , <http://ecowlim.tfri.gov.tw/lode/data/flyhorse/CollectingEvent/10015?output=xml> ; <http://rdfs.org/ns/void#sparqlEndpoint> <http://ecowlim.tfri.gov.tw/sparql/query> ; <http://xmlns.com/foaf/0.1/homepage> <http://ecowlim.tfri.gov.tw/lode> . |
NOTE: no prefix was found on prefix.cc for CKAN !?! This would have simplified the above listing .
The EulerGUI project gathering the step 1,2,3 is : ckan_explore.n3p .
Now that I found this data source, ckan:linked-open-data-of-ecology , I can start again the same steps : Getting the properties and classes used; ??????? WIP ?????????
BAD NEWS ! running this on data source ckan:linked-open-data-of-ecology :

On IRC chat #eulergui
EG has trouble reading http://purl.org/dc/terms/ ; probably some content-type that was not foressen
no, it works and returns appplication/rdf+xml , one of the types requested ;
<jmvanel_> the bug is after and mine
<jmvanel_> somewhere in project.addN3Source(n3);
<jmvanel_> somehow RDF/XMl is sent to Euler , which dislikes this :(
<jmvanel_> FYI Euler is used when adding an N3/RDF source to create rules for OWL patterns like rdfs:subclassOf , etc
==> the root cause was that there is a missing feature in N3 Java parser :
"string"@en-US
about language tag :
<jmvanel_> the answer is simple for me : if CWM and Euler accept it , then accept it too ...
<jmvanel_> however ...
<jmvanel_> I discovered the issue in DC terms , and it might be a problem with the RDF ==> N3 translation in Jane
<jmvanel_> indeed , DC terms has lots of xml:lang="en-US"
<jmvanel_> gotten directly by :
<jmvanel_> wget –header="Content-Type: application/rdf+xml" http://purl.org/dc/terms/

http://ckan.net/package?q=plants : 17 responses , but not all botany, because of words synonymy
<jmvanel__> there is an API :) to ckan
btw that's the kind of test you could do with EG ; EG is also a general purpose semweb tool ( I should avertise this more )(
back to kcan )
<jmvanel__> I tried to open one linked data in EG : http://ckan.net/package/taxonconcept ; this is view as web page in the Web browser ;
<jmvanel__> and I hoped that with EG accept-content headers I would get N3 / RDF
<jmvanel__> ok , that also what EG does
<jmvanel__> and IT WORKS !!
( started grahpviz on http://ckan.net/package/taxonconcept in EG ; run since minutes :(( )
( EG use with LOD : tried "add refered ontologies to current project", but to visible effect , and no log :(( )
( EG use with LOD : the interesting triple in http://ckan.net/package/taxonconcept is : <http://ckan.net/package/taxonconcept> void:sparqlEndpoint <http://lsd.taxonconcept.org/sparql>
Could be a nice feature for EG to record all void:sparqlEndpoint triples , and reuse them endpoints in the SPARQRL feature
( EG use with LOD : tried in the editor : control A ; edit / text / format paragraph ==> it adds eol's after column 80 , and it DOES touch strings :(((
another irritating bug in EG : the default dir for saving is ..
The proof vocabulary is in http://www.w3.org/2000/10/swap/reason# .
The EulerGUI project eulergui/examples/proofVerbalization.n3p is an example of both proof explanation and XHTML generation.
Structure of the RDF graph of a proof explanation
A r:Proof
has r:component
's ; and
r:gives
some triples.
The r:component
's typically are r:Inference; which r:gives some
triples for conclusion; and has r:evidence
's.
The r:evidence
's is rdf:List whose elements are either
r:Extraction (i.e. simple extraction from the facts and rules), or r:Inference,
or r:binding
, or r:rule .
An r:Extraction has a property r:because which is a r:Parsing , having a r:source which is the URI of the N3 source.
A r:binding has a r:variable, that has an n3:uri ( a string like "http://localhost/var#x3" ), a r:boundTo property which represents the value , and has an n3:uri .
An r:rule is an r:Extraction , that has an r:gives property (the rule N3 text), etc.
Here is the proof explanation in the above project ; to obtain it, uncheck the box near the post-processing project button. The output of the original project is an XHTML document as a string.

Its is RDF.

2) ensure with paraphrase that the semantics is what is intented
3) check vocabulary coherence and check for synomyms, generalisations
4) try to align properties and classes with a well known ontology (FOAF, DC, etc)
5) write a test with EulerGUI to check the desired inferences
6) design the applicative architecture (choose inference engine, populate the user RDF graph, extract inferences or set callback/listeners, ...)
7) write applicative test
8) implement the bridges between rule base and platform services ( database, GUI, network, etc )
Remarks
genenerally, you would separe business logic and applicative logic ( what to show and ask to user and when )

Overview of noun water
The noun water has 6 senses (first 4 from tagged texts)
1. (136) water, H2O -- (binary compound that occurs at room temperature as a clear colorless odorless tasteless liquid; freezes into ice below 0 degrees centigrade and boils above 100 degrees centigrade; widely used as a solvent)
2. (41) body of water, water -- (the part of the earth's surface covered with water (such as a river or lake or ocean); "they invaded our territorial waters"; "they were sitting by the water's edge")
3. (2) water -- (once thought to be one of four elements composing the universe (Empedocles))
4. (2) water system, water supply, water -- (a facility that provides a source of water; "the town debated the purification of the water supply"; "first you have to cut off the water")
5. urine, piss, pee, piddle, weewee, water -- (liquid excretory product; "there was blood in his urine"; "the child had to make water")
6. water -- (a liquid necessary for the life of most animals and plants; "he asked for a drink of water")
So the first sense is not the one most "important"; it is the sixth sense in my opinion.
Now let's look at the "inheritance" structure of the sixth sense :
% wn water -hypen -n6 Synonyms/Hypernyms (Ordered by Estimated Frequency) of noun water Sense 6 water => liquid => fluid => substance => matter => physical entity => entity => part, portion, component part, component, constituent => relation => abstraction, abstract entity => entity => food, nutrient => substance => matter => physical entity => entity => nutrient => substance => matter => physical entity => entity
I hope that this synset corresponds (enough !) the Attempto notions of mass noun:
In [78]: wn.synset('matter.n.03').definition Out[78]: 'that which has mass and occupies space'
Why is it so ? bug or feature ?
In [92]: wn.synset('topic.n.02') == wn.synset('matter.n.03') Out[92]: False

<jmvanel_> I'm hoping to make something usable for people like you
<jmvanel_> it's just a matter of having the critic mass ( users providing feedback ==> enhancement ==> more users )
* danbri suggests a super-quick-start guide showing simplest useful use case
<danbri> and have sensible defaults everywhere! the app offers lots of choice ( = complexity)
<danbri> if it can't find "Cwm", ... it shouldn't offer a Cwm option, etc

Reference: SPARQL queries as N3 sources in EulerGUI Manual
At first I tried the default query on the DBPedia URI (http://dbpedia.org/sparql) , with a web browser :
select distinct ?Concept where {[] a ?Concept} |
Then I wrote the equivalent CONSTRUCT query :
CONSTRUCT { ?C a ?Concept } where { ?C a ?Concept } |
Alas, this does not work :
Virtuoso S1T00 Error SR171: Transaction timed out
I retried with an extended query and 300 000 ms timeout :
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> CONSTRUCT { ?C rdfs:subClassOf ?SUPER. } where { ?C a ?Concept. ?C rdfs:subClassOf ?SUPER. } |
... and ... IT WORKS ! in one second . So it appears that the original query was too general for Virtuoso to optimize it. This is not the subject matter, so let me return to the original subject of exploring DBPedia with EulerGUI.
Note that this query does not bring the top level classes. An elegant way to do that is, assuming that each class has at least one label or other documentation property:
CONSTRUCT { ?Concept ?P ?O. } where { ?C a ?Concept. ?Concept ?P ?O. } |
However, Virtuoso does not like this elegance and (on the web interface) says:
Virtuoso 37000 Error SP031: SPARQL compiler: Variable 'Concept' is used in the query result set but not assigned
Unchecking "Rigorous check of the query" does not bring an answer with the web interface, because of timeout.
Anyway, these queries allows to build the class tree in EulerGUI (click on "launch OWL reasonner" in tools menu). One can see that the Wikipedia ontology has 2837 classes. The classes are taken from OpenCyc, Sumo, Umbel, and certainly others. The level of generality (granularity) varies greatly. It's obviously an ontology made of bits and pieces ( "faite de bric et de broc"@fr ).
This variant brings labels and comments if present, but still does not give the top level classes:
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> CONSTRUCT { ?C rdfs:subClassOf ?SUPER; rdfs:label ?L; rdfs:comment ?COM. } where { ?C a ?Concept. ?C rdfs:subClassOf ?SUPER # cannot be OPTIONAL OPTIONAL { ?C rdfs:label ?L } OPTIONAL { ?C rdfs:comment ?COM } } |
This variant supposes that all classes are declared as OWL classes, which may not be the case on some serveurs:
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX owl: <http://www.w3.org/2002/07/owl#> CONSTRUCT { ?C rdfs:subClassOf ?SUPER; rdfs:label ?L; rdfs:comment ?COM. } where { ?Concept a owl:Class. ?C rdfs:subClassOf ?SUPER # cannot be OPTIONAL OPTIONAL { ?C rdfs:label ?L } OPTIONAL { ?C rdfs:comment ?COM } } |
Get list of all properties in DBPedia
with SPARQL select query :
SELECT DISTINCT ?P WHERE {?S ?P ?O} |
with N3 query:
:d eu:findall ( ?P {?S ?P ?O} ?PLIST ). |
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> CONSTRUCT { ?P a rdfs:Property. } where { ?P a rdfs:Property. } |
empty result !
PREFIX owl: <http://www.w3.org/2002/07/owl#> CONSTRUCT { ?P a owl:DatatypeProperty. } where { ?P a owl:DatatypeProperty. } |
736 lines
PREFIX owl: <http://www.w3.org/2002/07/owl#> CONSTRUCT { ?P a owl:ObjectProperty. } where { ?P a owl:ObjectProperty. } |
632 lines
How to do logical or with SPARQL ? With UNION or OPTIONAL . So here is a way to combine the two preceding queries :
PREFIX owl: <http://www.w3.org/2002/07/owl#> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> CONSTRUCT { ?P a rdfs:Property. } where { { ?P a owl:ObjectProperty } UNION { ?P a owl:DatatypeProperty } } |
1365 lines.
Get list of all properties for a specific individual; this SPARQL query outputs all triples about an URI (DBpedia: Buddy_Guy) and the rdfs:label on properties used:
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX dbpedia: <http://dbpedia.org/resource/> CONSTRUCT { dbpedia:Buddy_Guy ?p ?v . ?p rdfs:label ?pname . ?p rdfs:comment ?pcomment . } WHERE { dbpedia:Buddy_Guy ?p ?v . OPTIONAL { ?p rdfs:label ?pname } OPTIONAL { ?p rdfs:comment ?pcomment } } |

Now watching this parser in OCAML for ACE Attempto : https://github.com/ontologiae/DRS-Analysis-Tool
After reading http://cworth.org/hgbook-git/tour/ , I cleaned my bad merge this way :
cd ~/src/sulci_jmvanel/ git fetch origin git reset --hard origin |
( following this advice : http://stackoverflow.com/questions/101752/aborting-a-merge-in-git )
Now , after reading this http://stackoverflow.com/questions/4169832/update-my-github-repo-which-is-forked-out-from-another-project, I did:
cd ../sulci git pull cd ../sulci_jmvanel git pull ../sulci |
So , I know that ../sulci is the "parent" from which sulci_jmvanel has been
cloned, but it's not the origin
that git knows; the
origin
is
the github remote depot of it .
To restrict the discussion, it's about the ACE core, not the User Input projects (ACE View, ACEWiki, etc).
"attempto" <attempto@lists.ifi.uzh.ch>, jean.philippe.fauconnier@gmail.com, "Pierre-Alexandre Voye" <ontologiae@gmail.com>, "Olivier Cayrol" <Olivier.Cayrol@logilab.fr>,
I think that the most important missing features in ACE are related to lexicons. There are several issues. The first is that there are several formats for ACE lexicons : one on core ACE, one in ACEWiki, another within OWL files in ACEView.
The second is that currently available lexicons are quite small.
I have 2 proposals for that.
I can start from this word list available on Linux (Ubuntu) :
/usr/share/dict/american-english
It's a plain word list with 1 word per line. For example it has both "studies" and "study" .
Then, for each word, I can use WordNet Lemmatizer in NLTK [1] to lemmatize it (that is, associate "studies" to "study" ). Each such pair will be added to an associative array. After processing the file this way, it's esay to output the lexixon formats for ACE tools. The WordNet API in NLTK will also be used to find out if it's a noun or a verb.
Example of using NLTK for lemmatization
import nltk nltk.download() wordnet from nltk.stem.wordnet import WordNetLemmatizer lmtzr = WordNetLemmatizer() lmtzr.lemmatize('cars') |
The 2nd proposal is to reuse OWL ontologies to obtain ACE lexicons. That will be in another mail ...
[1] NLTK Natural Language Toolkit - http://www.nltk.org/
ontologies in the broad sense should be reusable with Attempto. The motivation is that today a knowledge is not built in isolation anymore. Rather, for interoperability and ease of development, well established and good quality domain ontologies are used as starting point.
These
The passive can be the regular form, e.g. :
Attempto foaf-fundedBy EEC .
Even NL sentences have to refer to non-ambiguous word senses .
This is what I try to explain here ( in french :( ) :
http://jmvanel.free.fr/ai/comprehension-sans-protocole.html
Attempto is not enough, the word senses must be disambiguated as I said above.
This can be added quite easily to Attempto by RDF/N3 prefixed URI 's like foaf:Agent in this example :
Every foaf:Person is a foaf:Agent .
which is not accepted today by Attempto . But this is correct Attempto :
Every foaf-Person is a foaf-Agent .
foaf:Agent is a concept well defined by an ontology ( http://xmlns.com/foaf/spec/ ) , and moreover this FOAF ontology is widely used, which is good for interoperability, even without prior protocols or conventions.

jmvanel_> is there a command to create a plain vanilla Maven project ?
<whaley> jmvanel_: i always use `mvn
archetype:generate
`... the default value for archetype will give you a
"vanilla" java project
When running plugin maven-assembly-plugin 2.2.1 with jar-with-dependencies, and there is a class C1 in src/main/java/ that overrides a class in some dependency, in the resulting XXX-jar-with-dependencies.jar the C1.class comes from the dependency, not from the source in project.
I would except the class from the source in project to override the corresponding class in jar dependency,
So the executable jar is not built correctly. This is particularly annoying, because the tests pass , but the executable jar is not correct.
You can see this in the test project attached, where I override class TestCase of JUnit , adding a main , and setting this overriden class as the main class :
% java -jar target/maven_bug_build_override_class-1.0-SNAPSHOT-jar-with-dependencies.jar
Exception in thread "main" java.lang.NoSuchMethodError: main
( the original class TestCase of JUnit has no main ).
The executable jar was corrupted at the stage of building, so the tests passed , but with the executable jar it was impossible to open the N3 editor .
A snapshot is uploading at the usual place : http://eulergui.sourceforge.net/tmp/
I had to apply this hack after mvn package :
cd target/classes zip -r ../eulergui-1.9-SNAPSHOT-jar-with-dependencies.jar . cp ../eulergui-1.9-SNAPSHOT-jar-with-dependencies.jar \ ~/.m2/repository/eulergui/eulergui/1.9-SNAPSHOT/ cd ../.. |

* #ratpoison :http://ratpoison.sourceforge.net
<jmvanel__> cthuluh, X: user not authorized to run the X server, aborting.
<cthuluh> 8)
<cthuluh> wait, are you trying this from within your current X session?
<jmvanel__> yes :( ; i shoulld use the functions keys to get a console
<cthuluh> perhaps startx -- :1 # would be enough
<jmvanel__> no, not enough
<cthuluh> ok then try it from a tty :)
<jmvanel> yeah !!!
<jmvanel> it works ; I did Control Alt F3 :) first
<cthuluh> cool. now you can enjoy the (almost too) rich interface of ratpoison!
<jmvanel> but It's not what I expected ... opened a terminal by control t c ; then in gnome terminal, I did File / open terminal ; but there is no tiling by ratpoison :( ; the original terminal still ocupies the whole screen
<jmvanel> also started xchat ; again it ocupies the whole screen
<cthuluh> sure
* necrodearia est parti (Ping timeout: 276 seconds)
<cthuluh> just split your screen
<jmvanel> how ?
<cthuluh> C-t ?
<jmvanel> thanks ; after typing several control alt FX , I lost every X server :(
<cthuluh> huhu
<cthuluh> your primary one is probably on tty7. the newest one is probably on tty8
<jmvanel> with Control Alt F8 I get my regular gnome environment ;
<jmvanel> but I lost ratpoison :(
<jmvanel> following your advice , I started ratp with startx -- :1
<cthuluh> hmmm. on debian, or on ubuntu?
<jmvanel> on ubuntu I try ratp ; on debian I chat with you on my laptop
<jmvanel> with Control Alt F7 I get OS start messages
<cthuluh> ah. beware of the great ubuntu gremlin
<jmvanel> :)
* necrodearia (~mizery@unaffiliated/necrodearia) a rejoint #ratpoison
<cthuluh> try ps aux | grep X
<cthuluh> it should give you the consoles on with X servers are running
<jmvanel> I 'm afraid I can't tame the gremlin
<cthuluh> then shred it ;)
<cthuluh> there's no reason for your ratpoison instance to disappear
<jmvanel> with Control Alt F3 I get the startx messages for ratp , but no graphical environment
<cthuluh> and with F9 ?
<jmvanel> yeah , fine !!!!!!!
<jmvanel> F9
<jmvanel> I'm reallly dumb with these keys
<cthuluh> 8)
<jmvanel> so, now I try control t 1 , 2 etc to switch windows
<jmvanel> it works , but NOT with the numbers in the number keys on ther right :(
<jmvanel> looks like a bug somewhere ...
<cthuluh> hmmm
<jmvanel> and how to tile my windows ?
<cthuluh> read again the topic: no handholding ;)
<cthuluh> I don't get your first question
<jmvanel> about the number keys ?
<cthuluh> the numeric keypad doesn't work?
<jmvanel> right
<cthuluh> is the led turned on, when you're in ratpoison?
<jmvanel> yes , and I use it always
<cthuluh> then I have no idea
<jmvanel> works fine in gnome
<cthuluh> well
<cthuluh> can you type numbers using it, in ratpoison?
<cthuluh> (start an xterm, type 123)
<jmvanel> the numeric keypad does work within rp , inside a terminal or xchat, but NOT with control t
<jmvanel> ( it' possible that ubuntu has an old version of rp )
<jmvanel> expreimented control t s :))
<jmvanel> How can I rremove Command
<jmvanel> Kill the current frame. This is a no-op if there is only one frame.un this :
<jmvanel> How can I run the remove Command ?
<jmvanel> I did Cntrl t cntrl k ; it closed the current frame , BUT its space is still occupied by a black zone that is unused by any remaining frame :(((

Welcome to IPython. I will try to create a personal configuration directory
where you can customize many aspects of IPython's functionality in:
/home/jmv/.ipython
Initializing from configuration: /usr/lib/python2.7/dist-packages/IPython/UserConfig
Successful installation!
Please read the sections 'Initial Configuration' and 'Quick Tips' in the
IPython manual (there are both HTML and PDF versions supplied with the
distribution) to make sure that your system environment is properly configured
to take advantage of IPython's features.
Important note: the configuration system has changed! The old system is
still in place, but its setting may be partly overridden by the settings in
"~/.ipython/ipy_user_conf.py" config file. Please take a look at the file
if some of the new settings bother you.

This is a good example of ambiguous pronoun reference :
If a bearer has a payment-incident then its order is canceled.
Paraphrase : If a bearer has a n:payment-incident X1 then an order of the n:payment-incident X1 is a:canceled Remedy 1 : BAD : If a bearer B has a payment-incident then the orders of B are canceled.
Paraphrase : If a bearer X1 has a n:payment-incident then at least 2 orders of the bearer X1 are a:canceled .
Remedy 1 : GOOD : If a bearer B has a payment-incident then every order of B is canceled.
Paraphrase : If a bearer X1 has a n:payment-incident then if there is an order X2 of the bearer X1 then the order X2 is a:canceled .
En Français :
Si un porteur B a un incident de paiement, alors chaque commande de B est annulée.

Looking for a semantic web simple navigator application that pretty prints RDF with resources as clickable hyperlinks . It could be stand alone or a browser plugin.
Of course it's not as simple as that, because common sens rules have be applied :
do not change page, and change the resouce Res1 style to non- hyperlink
or try sindice or other sites
hg clone http://dig.csail.mit.edu/hg/tabulator/
At launchpad they have that ( no N3 directly available ) :
<?xml version="1.0" encoding="utf-8"?> <rdf:RDF xmlns:doaml="http://ns.balbinus.net/doaml#" xmlns:foaf="http://xmlns.com/foaf/0.1/" xmlns:lp="https://launchpad.net/rdf/launchpad#" xmlns:wot="http://xmlns.com/wot/0.1/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <lp:Product> <lp:specifiedAt rdf:resource="/lena/+rdf"/> <lp:name>lena</lp:name> <lp:displayName>LENA</lp:displayName> <lp:title>LENA - a Fresnel LEns based RDF NAvigator with SPARQL selector support.</lp:title> <lp:shortDescription>LENA stands for LEns based NAvigator. A lens represents a particular view onto RDF data and is described by the Fresnel Display Vocabulary. LENA enables viewing RDF data in your web browser, rendered according to the lens descriptions you provide. LENA supports the use of multiple lenses and indicates if they are available for a resource, so that a different view onto the same data is always just one click away! To write lenses for complex RDF structures created through sophisticated ontology frameworks like COMM or X-COSIM, LENA supports SPARQL selectors. As comprehensive query language for RDF, SPARQL complies to the requirements needed to select from these complex structured RDF graphs. While a Fresnel SPARQL selector is a designated Fresnel selector an implementation did not yet exist. LENA provides an extension to support Fresnel SPARQL selectors that is now integrated into the Simile Fresnel engine. The data which shall be processed by LENA, can either be put into the provided directory or be accessed through a Sesame HTTP repository. For more information about the usage of LENA see the FAQ. </lp:shortDescription> <lp:description></lp:description> <lp:creationDate>2008-07-16 13:38:24 UTC</lp:creationDate> <lp:homepage rdf:resource="http://isweb.uni-koblenz.de/Research/lena"/> <lp:series> <lp:ProductSeries> <lp:specifiedAt rdf:resource="/lena/trunk/+rdf"/> </lp:ProductSeries> </lp:series> <lp:owner> <foaf:Agent> <foaf:Account rdf:resource="/~tastentom/+rdf"/> </foaf:Agent> </lp:owner> <lp:status>Active</lp:status> </lp:Product> </rdf:RDF> |

Happily it follows the same schema as RDF mapping for WordNet version 2 (http://www.w3.org/TR/wordnet-rdf/#introduction ).

Indeed, this symbol is undefined in libjpl.so, and defined in libswipl.a :
objdump --syms /usr/lib/swi-prolog/lib/amd64/libswipl.a | grep PL_is_initialised
0000000000000000 g F .text 000000000000003b PL_is_initialised
The remedy was to add /usr/lib/libswipl.so in LD_PRELOAD .
export LD_PRELOAD=$PLBASE/lib/$PLARCH/libjpl.so:/usr/lib/libswipl.so
It works also on Ubuntu 11.04 ; you have to add package swi-prolog .

Résumé
Mr. Bryan B. Thompson is the co-founder and Chief Scientist of SYSTAP, LLC. His technical background includes expertise in cloud computing; the semantic web; web architecture; relational, object, and RDF database architectures; knowledge management and collaboration; artificial intelligence and connectionist models; natural language processing; metrics, scalability studies, benchmarks and performance tuning; decision support systems; and usability design. Significant developments include:
•The creation of bigdata®, an open source distributed database. Bigdata® is commercial licensed through OEMs and is used within in the intelligence community, telecommunications industry, managed storage networks, heath care, bioinformatics, etc.;
•The synthesis of a cognitive model of human reasoning about risk and uncertainty (“Recognition / Metacognition theory”: Cohen, Freeman & Thompson, 1998) with a connectionist model of human reflexive inference (“Shruti”: Shastri & Ajjanagadde 1993; Shastri, 1996) that provides a cognitive and computational explanation and model of expertise and critical thinking behaviors;
•Novel extensions to the IBIS architecture include support for reasoning with positive and negative evidence, support for planning, and support for engaging individuals in critical thinking dialogs that identify the sources of uncertainty in their expressed arguments.
•A class of optimal incremental planners (Thompson and Cohen, 1999) and their application to sophisticated knowledge models within an architecture for a connectionist reasoner (“Shruti”; Shastri, http://www.icsi.berkeley.edu/~shastri/shruti);
•An adaptive control methodology known as Action Dependent Heuristic Dynamic Programming (Lukes, Thompson and Werbos, Jan 1990). This method was first and most extensively published by Watkins as Q-Learning in his doctoral thesis (Watkins, 1989).

<jmvanel_> Hi
<jmvanel_> I get comile erroes "unification error in needed statement" for simple examples like Lengh of a list in Van Roy 's book 's .
<jmvanel_> I suspect something wrong in my installation
I forgot the declare keyword at the begining !
I'm also reading about ozma, as someone here suggested .
<jmvanel_> And I ordered Van Roy's book in french .
The ozma thesis by Sébastien Doeraene actually allows to learn in parallel ;) Scala and Oz .
This was a little exercise to correct the syntax:
declare fun {Learn Language} Language end Knowledge = [thread {Learn 'OZ'} end thread {Learn 'Scala'} end ] {Browse Knowledge} |
I found a bug in the OPI : when feeding region { Send P 1
;
missing }, it says ------- accepted and nothing happens
I can run demo/Bounce.oz like this : ozc -x Bounce.oz ; ./Bounc
but I don't know how to run it in emacs.
I like this sentence:
Hence, introducing the thread has not changed the global effect of the program.

TODO read "Logic Programming" in Tutorial of Oz :

Dialog on #oz
If I compare Oz with Mercury, I note:
Mozart has a problem with porting to 64-bit, see "Mozart Project Ideas"
Oz seems to be written in C++, not in Oz :( (while Mercury is written in Mercury)
Oz is not running on a JVM
Functionality "Dataflow concurrency" is very interesting. I know of no language that has it .
Oz started from a more global thought , whereas Mercury started as adding functional features to Prolog, while removing the Prolog hacks like cut, etc
<jmvanel> I'm glad with the book by Van Roy, the Oz tutorail, and other material, but I have the usual questions:
<jmvanel> list of real projects in productions using Oz ; roadmap for new features
<jmvanel> another question is : is there a library for SemanticeWeb ?
<jmvanel> in case ... of , why is used [] as a separator between patterns ? Normally [] represents the empty list as in Prolog ...
jmvanel> From experience, maintaining an IDE GUI like EulerGUI, with its extensive non-regression tests, even if it's time consuming, is nice because there is something that works, and continues to work while features grow .
<jmvanel> Of course features grow at a slow pace because the code quality is too low as I wrote .
<jmvanel> Also I think it's important to leverage on Semantic Web standards, even though it's just about data portability .
<_KY_> Semantic web has its limitations
<jmvanel> It also goes a good way in the direction of concepts portability .
<jmvanel> sure
<_KY_> The logic used is sometimes not expressive enough
<jmvanel> sure
<_KY_> I think what's critical is that the entire system must be capable of evolving
<jmvanel> they took the limitations from DL theory
From experience, maintaining an IDE GUI like EulerGUI, with its extensive non-regression tests, even if it's time consuming, is nice because there is something that works, and continues to work while features grow .
Nice general practical notes on Java
http://www.leepoint.net/notes-java/
I tried this nice Prolog equivalent in Mozart :
proc {Append ?A ?B ?C} choice A=nil B=C [] As Cs X in A=X|As C=X|Cs {Append As B Cs} end end {Browse {SolveAll proc {$ S} X#Y=S in {Append X Y [1 2 3]} end}} |
But it answers :
variable SolveAll not introduced
I have to work the basic syntax ...
The Mozart Browser "allows you to see the evolution of the instantiation of a term as concurrent computations (threads) proceed and add more information".
DOES NOT WORK:
mport Solve proc {Append ?A ?B ?C} choice A=nil B=C [] As Cs X in A=X|As C=X|Cs {Append As B Cs} end end {Browse {SolveAll proc {$ S} X#Y=S in {Append X Y [1 2 3]} end}} |

About the enhanced Pascal program, FastTriangle, in the book by Van Roy, is there a compiler option to automatically save the duplicated function call into a variable, or issue a warning ?
The original Pascal program,
fun {ShiftLeft L} case L of H|T then H|{ShiftLeft T} else [0] end end |
The FastPascal enhanced Pascal program:
fun {FastPascal N} if N==1 then [1] else L in L={FastPascal N-1} {AddList {ShiftLeft L} {ShiftRight L}} end end |

There should be a generic mechanism in N3/Drools engine for a property with
cardinality one. If the property would be a Java Property, it would be
automatic. The second rule below is not a good mechanism, because
app:currentUserLanguage
triples are never removed. I see these
solutions:
{ # when a new language is asserted, apply it
app:currentApplication app:userLanguage ?LANG .
?GUI a java:n3_project-ProjectGUI .
} => {
?GUI javap:language ?LANG .
app:currentApplication app:currentUserLanguage ?LANG .
_:d eg:trace ( "userLanguage: called javap:language " ?GUI ?LANG ).
}.
{ # when a new language is asserted, and it is different from the old one, delete the old one
# TODO should be a generic mechanism for a property with cardinality one
# maybe keep the javap: properties asserted in the KB

How to enforce max Cardinality with rules ?
{ ?C owl:maxCardinality ?MAX. ?C owl:onProperty ?P. _:d eu:findall ( ?SUBJECT { ?O ?P ?SUBJECT } ?SUBJECTS ). ?SUBJECTS math:memberCount ?COUNT . ?COUNT math:greaterThan ?MAX. } => { false # ??? }.
It seems better to control input , as this is obviously a closed world feature.
This is the "concrete" example:
If there is a n : concrete X1
then the n : concrete X1 v : contains a n : cement
and the n : concrete X1 v : contains a n : granulate .
This is also the "koala" example:
:Animal a owl:Class ; rdfs:seeAlso "Male" ; rdfs:subClassOf [ a owl:Restriction ; owl:minCardinality "1"^^<http://www.w3.org/2001/XMLSchema#int> ; owl:onProperty :hasHabitat ] ; rdfs:subClassOf [ a owl:Restriction ; owl:cardinality "1"^^<http://www.w3.org/2001/XMLSchema#int> ; owl:onProperty :hasGender ] |

I added starDict with a couple of dictionaries; everytime you select a word anywhere, a popup appears with definitions.
<jmvanel_> I'm ready for an EG release; couldn't find anyone on swig for testing :(
<jmvanel_> found this possibly interesting community : #Genifer, but they don't talk much
<jmvanel_> now I'm working to clean things in EG with the internal KB so that applicative rules can be triggered whenener something happens. As a concrete case, redraw the GUI when user update the preference N3 file.
The sequence of events:
~/.eulergui/preferences.n3
which replaces the old one in the
KBapp:currentApplication app:userLanguage "de" .
replaces the old one
Is there a standard design pattern in rule to have new inserted value of MyClass . myField replace the previous one ?
I mean assume :
class MyClass { public String myField ; }
insert object o1

Dialog on SWIG IRC
Hi any recommendation for a vocabulary about materials, e.g. "cement and granulate are Materials which are components of the concrete Material; the notion of component includes a percentage"
SUMO seems to have these concepts
<zazi> jmvanel_, I dunno a good vocabulary on that, however a funny jingle on cement in German ;) http://download.fritz.de/jingles/Fritz_Entschuldigung_Zement.MP3
<jmvanel_> :)
<jmvanel_> SUMO in OWL in 36 Mb ! :( attempt to load it in Protégé from HTTP fails ! But wget got it , and from that local file Protégé said "OutOfMemoryError: Java heap space"
<jmvanel_> not asking for help on that ...
<jmvanel_> but what is needed is a small vocab ...
<zazi> btw, what about dbpedia?
<jmvanel_> good idea
http://downloads.dbpedia.org/3.6/dbpedia_3.6.owl.bz2
<jmvanel_> zazi, FYI, I could this time load dbpedia ontology in Protégé :) , but not directly the bz2 URL ) ; however dbpedia is strong in science and technics :(

DISPLAY=localhost:0.0 gvim -c 'a|bisous !!!!!!!!!!!!!!!!!.' E233: ouverture du display impossible
This was a problem that was here for more than a year. One of the dependency jars, jEdit, that was prepared for this project on our Maven depot, had all classes duplicated in a wrong directory classes/ in the jar. This was badly interaracting with recent changes in Maven. As a consequence, the jEdit editor windows were not working.
This is now fixed, and if you build from sources, these command should get you going :
rm $HOME/.m2/repository/org/jedit/jedit/4.3.1/jedit-4.3.1.jar mvn clean rm -r $HOME/.m2/repository/eulergui/eulergui/1.9-SNAPSHOT/ mvn -Dmaven.test.skip=true install |
Asked on Maven IRC
I have a class C1 (jEdit) that is in src/main/java , and also in one (direct) dependency ; this used to work for a long time , and since a few days the C1 from the dependency seems to be chosen by the Maven build , plugin maven-assembly-plugin with predefined descriptor jar-with-dependencies .
What happens is that it copies all classes from dependencies, and when C1 comes from source, it says "C1.class already added, skipping".
What puzzles me is that I can't go back to a version that works.
Note that Surefire (and eclipse) work fine about this.
it's not normal that the classes made with maven-assembly-plugin with predefined descriptor jar-with-dependencies differ from those executed by surefire.
I noticed something strange : inside the generated jar-with-dependencies.jar for the problematic dependency, classes are duplicated : once normally, and once in a classes/ directory . And this happens only for this dependency .
OK, I removed the useless classes/ directory in the dependency jar , plus also the manifest , and it works now !
<jmvanel> my guess is that Maven assembly tries to be too smart , and takes classes that are not at the root of the dependency jars ;
<jmvanel> and this behavior is recent .
I got the same problem again on the laptop, even after republishing the jar that was bad on our repository. After running mvn install one time unsuccessfuly, I removed the generated eulergui-1.9-SNAPSHOT-jar-with-dependencies.jar from the local repo, but not the source jar .
The whole issue may be related to an artifact without source jar .
need visualizers for RDF graphs: as table, as graph.
could just generate an HTML table from an N3 template with eu:format .

COMMIT
After recent class moves refactoring , test suite was broken due to hard coded packge path in Drools N3 engine.
any way to move *several* methods together from one class C1 to class C2 of one field of C1 ?
( works with one method at a time )
Is there a plugin that tells which methods can become private or package visible ?
According to stackoverflow.com , findbugs seems the best before PMD and Checkstyle ; so I ran :
mvn findbugs:gui
http://findbugs.sourceforge.net/contributing.html
The machine is running Windows 7, with latest JDK 25 .
I installed: JDK, Maven 3.0.3, Subversion, Cygwin (facultative).
Then I ran this with the Cygwin shell:
svn co https://eulergui.svn.sourceforge.net/svnroot/eulergui/trunk/eulergui eulergui export PATH=~/apps/apache-maven-3.0.3/bin:$PATH export JAVA_HOME="C:/Program Files/Java/jdk1.6.0_25" export M2_HOME=C:/cygwin/home/Daphné/apps/apache-maven-3.0.3 cd eulergui mvn install |
According to http://maven.apache.org/scm/subversion.html , it is necessary to create this file :
$user.home/.scm/svn-settings.xml
with (at least) this content:
<svn-settings> <configDirectory>C:\Users\Daphné\AppData\Roaming\Subversion</configDirectory> </svn-settings> |
I installed Subversion from subversion.tigris.org , hence the above configDirectory.
If you don't create this file, you can run svn commands directly from the cmd or Cygwin shell , but with Maven you get this ugly and hard to trace in internet message:
svn: Can't determine the user's config path |

Hi
I have an HP ProBook 4310s ; I follow the latest updates of Ubuntu 11.04, and since about 1 week there is a transient problem with the touchpad : after a few minutes it becomes very slow to react ; that is the pointer lags the motion on the touchpad.
And it's the same with an USB mouse.
Of course memory and disk have been checked.
When I work through an ssh console , it's fine.
I suspect a recent update ...
I'm using the gnome interface, but I think it's the same with Unity.
<jmv__> my vendor specializing in Ubuntu said I have better installing preceding Ubuntu release ...
<jmv__> I think I can try to solve this with community ...
<bregma> jmv__, it sounds like a problem in the kernel causing input event backlogs

TODO
With new translations of OWL subclass assertions to N3 rules as a pre-processing step, the Swing rule base should be changed, because some form fields are duplicated.
COMMIT
- refactor in TestJemmy the way to get the EuleGUI Frame : should fix the last Error in test suite in TestFacebookSearch
- Fix bad URI in testFieldOldArchitecture
TODO : test suite lasts now 17 minutes , N3 parsing or conversions probably occur 2 times
- Fix test suite, broken by new " has changed on " messages due to new translations of OWL subclass assertions to N3 rules
- call waitUpdateThreads in DroolsInferenceEngine (maybe not necessary, but more safe)

If you now open examples/koala.n3p with EG ( even version 1.8 ) , you see now a (partial ) translation of OWL into N3 rules , like :
{?VAR a ns2:Parent} => {?VAR a ns2:Animal}.
{?VAR a ns2:Person} => {?VAR a ns2:Animal}.
{?VAR a ns2:Animal} => true.

I just added an HTTP rule to a project that is run for each OWL/RDF sources :
deductions/n3_new/owl-subclass-assertions-to-rules.n3
The rule in red translates like this Drools , and this is not correct Drools:

It is possible to use string comparisons defined in CWM Builtins to also compare dates expressed in ISO (and XML Schema datatype) format.
They compare according to Unicode(tm) code order.
log:equalTo
string:equalIgnoringCase
string:greaterThan
string:lessThan
string:notEqualIgnoringCase
string:notGreaterThan
string:notLessThan
Here is a minimal example showing how to define that an event belongs to an interval . It supposes a minimal ontology with 3 properties hasStart , hasEnd, hasTime, and belongsTo :
{ ?INTERVAL :hasStart ?S ; :hasEnd ?E . ?EVENT :hasTime ?T . ?T string:notGreaterThan ?E . ?S string:notGreaterThan ?T . } => { ?EVENT :belongsTo ?INTERVAL. }.
Of source it is possible to modify this to support the owl-time ontology.
xsd:dataTime^^""
@prefix : <http://www.w3.org/TR/owl-time/> . :telecon a :Interval ; :hasBeginning :teleconStart . :meeting a :Interval ; :hasBeginning :meetingStart ; :hasDurationDescription :meetingDuration . :teleconStart a :Instant ; :inXSDDateTime 2006-11-05T18:00:00-5:00 . :meetingStart a :Instant ; :inXSDDateTime 2006-11-05T14:00:00-8:00 . :meetingDuration a :DurationDescription ; :minutes 45 .

it is necessary to delete the cache because same projects are compiled twice with and without useInsertLogical
- more thread safe fixes in N3SourcetoDrools : factPerN3Source, rulePackageNumber
DONE : still tailure in TestEulerGUITooltip ( probably the N3 parsing is not yet done when the test checks tooltips )
- N3SourcetoDrools: remove current_document , that is not thread safe
- N3SourcetoDrools: synchronize ruleBase; tripleResult : no need because no used in parallel N3 source processing
- N3SourcetoDrools: firstRule is moved to DroolsTripleHandler

I read an interesting discussion on "create HTML based on RDF?" on the public-lod mailing list.
Suppose an ontology like this:
|
N3 rules are well suited to express commercial or regulation rules, like determining a category, or estimating prices. However, It would not be convenient for complex mathematical computations, for example to express in N3 the computation of the surface of a room.
So these computations would be written in a imperative language, Java for instance. Then there are two implementation questions:
For point 1, we currently have nothing smart implemented, just access to the interface ITripleStoreRETE extending ITripleStore. But there are hints that need to be generalised, see Calling user Java code , Extension points with interfaces . Also there several projects for RDF to Java mapping frameworks, see Experience using Java-based frameworks for RDF-to-POJO (and vice versa) mapping, rdf2java, Tripresso .
For point 2, here is the recommended idiom:
# First, assign a Java class to an RDF resource: { ?CC a re:ClosedCurve. } => { ?CC a java:geometry-ClosedCurve . }. # Then, the computation is triggered, and the result goes into the RDF KB: { ?CC a re:ClosedCurve. # facultative ?CC javam:getSurface ?SURFACE. } => { ?CC re:hasSurface ?SURFACE. }. |

I discovered that the cause of random tests result lays in the FOAF site being often down.
I must catch the network timeout exception so that project loading can go on, and eventually the failing URI will be gotten by the URI checker thread.
http://classic-web.archive.org/web/20080611134628/http://xmlns.com/foaf/spec/index.rdf
Fixing the issues in EG regarding timeouts , and how to work best with failing URI's : they are flagged with N3Source.setAccessible(false) , and no more checked with manageN3Cache() .
Also exception are caught so that project loading can go on in case of failing URI's; just error windows are produced.

Now N3 shell (BasicRuntime) can show Déductions generated applications
- class N3SourcetoDrools : add Infrastructure Objects In WM (i.e. instance of GUIKBAdapter)
not only when calling LaunchDrools()
Now a rule base is only cached if the project has a permanent location.
So now testCreateProjectInGUI and testCreateProjectInGUI2() in TestFacebookSearch pass in succession .
They differ in reverting calls to pushRunDrools() and pushAddN3Search();
NOTE: The problem was possible because the Drools package name generated e.g. n3_project_helper0 , is not specific , which is not normally a problem because there is a Map associating the Drools package name with theN3 source.
I can reproduce deterministically this NullPointerException in addPackage : http://pastebin.com/sCtLMj7r
<jmvanel> with 5.1.1 ;
<jmvanel> does it make sense to try 5.2.0 BETA ?
I could not reproduce it on my laptop , then I cleaned in eclipse, and no NPE now.

The Drools is currently the following.
WHAT IS WRONG: ?E is actually universal (and moreover initialised by a Java
property, because its first appearance is here). So ?E cannot be treated as an
existential in the consequent , as it is below in red. Also, empty
is Java property with a primitive type, so it makes sense not to use the Java
reference variable $E_reference for it. I implemented this last
criterium.
rule "match_Java_object.n3 0" when $L_reference : java.util.List() Assignment( $L : name, reference == $L_reference ) java.util.List( $E_reference : empty , this == $L_reference ) then Triple newTriple; TripleResult newTripleResult; newTriple = new Triple( ); newTriple.setSubject( "<test/match_Java_object.n3#test>" ); newTriple.setPredicate( "<test/match_Java_object.n3#is>".toString() ); newTriple.setObject( "<test/match_Java_object.n3#ok>".toString() ); insertLogical( newTriple ); String E = Triple.resource("E") ; newTriple = new Triple( ); newTriple.setSubject( "<test/match_Java_object.n3#test>" ); newTriple.setPredicate( "<test/match_Java_object.n3#is>".toString() ); newTriple.setObject( E.toString() ); insertLogical( newTriple ); end |

FIX TestN3FormatForProject by updating project-java-rules.n3
- some defense against null URI's in N3Source and Project
- refactor a bit ApplicationKB
Added http://prefix.cc/kb
With the Drools N3 engine, I try to match a Java AWT FocusEvent, to actually catch the Focus Lost Events at runtime.
When working focus lost processing, I saw that the actuel event is not FocusEvent, but a platform-specific subclass :
FocusEvent.class.isAssignableFrom( e.getClass() ) (boolean) true e.getClass() (java.lang.Class<T>) class sun.awt.CausedFocusEvent |
So I need to change the Drools translation in antecedent from :
Assignment( $JEVENT : name, reference.class == java.awt.event.FocusEvent, $JEVENT_reference : reference ) |
to :
Assignment( $JEVENT : name, $CLASS_1 : reference.class,
$JEVENT_reference : reference )
eval( FocusEvent.class.isAssignableFrom( $CLASS_1 ) )
|
or , simpler :
Assignment( $JEVENT : name, $JEVENT_reference : reference )
eval( FocusEvent.class.isAssignableFrom( $JEVENT_reference.class ) )
|
Alas ! This is not not good , see this message:
org.drools.RuntimeDroolsException: Exception executing predicate reference.ID == "1005" ... Caused by: [Error: unable to resolve method: deductions.runtime.GUIKBAdapter.ID() [arglength=0]] |
This could not pass because FocusEvent has no no-parameter constructor , but it does not seem to be a problem .
$JEVENT_reference : FocusEvent()
Assignment( $JEVENT : name, reference == $JEVENT_reference )
|
But other Assignment conditions must still have
Assignment( $VAR : name, $VAR_reference : reference ) |
if VAR was never met before. So $JEVENT_reference should be recorded as a Drools variable with a type.
This creates the same RuntimeDroolsException. It seems that Drools never peeks into eval() expressions .
Assignment( $JEVENT : name, $JEVENT_reference : reference )
eval( $JEVENT_reference instanceof FocusEvent )
|
Next try :
$JEVENT_reference : FocusEvent()
Assignment( $JEVENT : name,
reference.class == $JEVENT_reference.class )
|
Now the property criteria should be changed from :
Assignment( name == $JEVENT , reference == $JEVENT_reference , reference.ID == "1005" ) |
to:
Assignment( name == $JEVENT , reference == $JEVENT_reference,
reference.class == $JEVENT_reference.class
reference.ID == "1005" )
|

Tomorrow will add http://prefix.cc/kb
deductions//n3_logical/person_import3.n3p.n3
erroneous , but works quite good !
On project deductions/n3_nojs/person-app.n3p
, Euler engine now
gives a quick result !
COMMIT in déductions :
n3_nojs/person-app.n3 : add callback in N3 that adds a label when user input is "JMV"
TODO :
the deferred method calls are probably re-created when firing rules; this should be avoided maybe by keeping the deferred method calls objects in a processed state, or actually adding the method call triples in the N3 KB (not sure ??)
Refactoring N3 Swing rule base will enable changing GUI platform.
TODO
With the new Swing rule base in n3_nojs/ , in 50% of the runs , the fields do not appear until the window is slightly resized.
COMMITS:
REFACTOR: move rules refering to java* prefixes to generic_to_java-rules.n3 ; still 43 to do :
grep --count java generic_gui_projection-rules.n3
43
- TestGenericGuiGenerationInsertLogical : test projects are now taken from deductions/n3_nojs/
- TestJemmy : to detect the EulerGUI JFrame , give it a name with setName()
DeferredMethodCall : enhance debug print
DeferredPropertyAssignment : FIX for focus lost in generated app.: Integer etc types are converted to String when method argument demands String.

So the long test problem disappeared, it was probably due to a server problem. In the long term, it would be nice to start a local server for tests.
However there is still a problem with post-processing projects :

All this will be easier and more stable with the new N3 file format backed by the internal Knowledge Base. Note that this vicious loop should be avoided:
add N3 source in KB => Java event => add N3 isource in KB
One possibility is to replace the N3 source collection in Project with a direct access to the KB.
maybe problem is obtaining timestamp from URI;
to avoid that, thought of keeping the last timestamp obtained, and only reconnect to the HTTP server if the timestamp is too old
on end each thread should send event "N3 fully prepared" for GUI;
join threads when all N3 source are fully prepared

Since I'm now working on a more flexible way of using the N3 Swing rule base (see application-examples.html ), it's time to refactor this rule base .
All things below DONE
TODO : remove javapr:projection here in generic_gui_projection-rules.n3 :

Due to deferred Java method calls created by the framework, the Java method add will be called as soon as called object and argument are bound to Java objects.
Also gengui:hasComponent is useless, as it is used only in consequents of rules.
Also, this rule must be moved to generic_to_java-rules.n3 , like all rules refering to java* prefixes .
And for every pair of triples such as :
?JBUTTON a gengui:Button . ?FIELD javapr:projection ?JBUTTON . |
replace it with:
?FIELD a gengui:Button . |
An in the rule every occurence of ?JBUTTON should be replaced with ?FIELD .
So we will get rid of the javapr:projection predicate altogether.
This is the rule design pattern "Annotate the existing objects".
This pattern is already used in generic_to_java-rules.n3 , e.g. :
{ ?W a gengui:Panel. javapr:thisApplication app:platform app:Java . } => { ?W a java:javax-swing-JPanel } . |

Commited in EulerGUI: eulergui/html/application-examples.html
This is a translation and enhancement of the seminal (!) post in french group deductions-fr "Applications exemples".
The user interaction is based on a simple semantics for user interaction, involving these concepts: CRUD data manipulations (CReate, Update, Remove), plus log, statistics, current tasks, represented by these imperative properties :
I propose to model declaratively user interaction with the concept of user transaction. A user transaction is a list of data manipulations.
A data manipulation is an elementary input from the user. There are four kinds of data manipulations for the two kinds of properties as defined in OWL (Properties "object" and properties "datatype"):
A data manipulation is associated with a subject and property in the OWL / RDF sense. Modification and destruction have in addition an object in RDF sense .
For example, adding a statement corresponds to the addition of an identifier article in a commercial order.
A creation of a new RDF identifier is the creation of a new bank account, for later making money transfers with it.
When you create a transaction via a rule, there is every possibility of the N3 language to add additional conditions. For example adding an ID article in a commercial order, we can restrict proposals to categories corresponding to the user's interests, or its past orders.
It remains only to create implementations for the language to user interaction through rules mixing Java and pure business. One can consider several implementations: Swing, GWT, SWT, command, etc..
To begin, one must write this small N3 vocabulary . We'll put it in the
project Deductions in owl/user_interaction.owl.n3
Here is an example of using the app:hasLogEntry predicate . Assume we are in the RHS of a rule (the consequent) . So a variable ?CONTACT, non existent in the left side of the rule (the antecedent) is a creation of a new identifier.
@prefix app: <http://eulergui.sf.net/ontology/application.owl.n3#>. :myApp app:log [ "Ajout d'un nouveau contact"@fr ?CONTACT ]. ?CONTACT a :Contact. |
Here is an example of using the app:hasStatistic predicate:
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . @prefix e: <http://eulersharp.sourceforge.net/2003/03swap/log-rules#> . { _:d e:findall( ?CONTACT { ?CONTACT a :Contact } ?CONTACTS ). ?CONTACTS math:memberCount ?NB_CONTACT. } => { ?S a app:Statistic. ?S rdfs:label "Nombre de contacts: "@fr . ?S app:information ?NB_CONTACT . :myApp app:hasStatistic ?S. }. |
It's possible to reuse the swing-rules3 rule base, with small modification to make it more flexible.
Currently, the infered GUI is only partly MVC (Model-View-Controler). The controler is provided by the rule base. However, the Views do not (yet) listen to the Model ( which is, for this framework , the RDF Knowledge Base).
The swing-rules3 rule base gathers all properties that are reachable from an RDF node, taking in account class assertions, domains, ranges , etc. However user interaction needs more flexibility:
For point 1, the trick is to design a class specific for the user interaction, plus rules to interpret the user interaction data, and transform it into regular ontolgy data that is stored in the Knowledge Base.
For point 2, we would like to write verification as pure domain rules, like this :
@prefix ded: <http://deductions.sf.net/owl/events#> . @prefix : <http://jmvanel.free.fr/ontology/examples/person#> . # <http://deductions.sf.net/owl/events#exception> { ?P a :Person . ?P :name "bush" . } => { ?E a ded:Exception ; rdfs:label " is already retired!" ; rdf:subject ?P ; rdf:predicate :name . } . |
Something close to this used to work in the very first version of the framework, where the focus lost listener was implemented 100% in Java.
It is possible to add in the Swing rule base rules to match ded:Exception, retrieve the associated input field widget, and reestablish the former value in the widget and the KB.
For point 3, the current framework with embedded Java objects allows to instatiate any custom widget , add it to relevant panel, and add it as a listener.
A typical inference flow :
application => main window and panels for data manipulations, log, statistics, current tasks user => create Form From Class ?C => create new RDF ID => create input widget for new RDF ID in data manipulations panel |
The user action to create a Form From Class ?C can be done in a specific button or menu entry, whose callback simply asserts the imperative RDF in the KB. Or, for the developer, the imperative RDF can be entered in the N3 shell.
The predicate in form-rules.n3 is used like this :
?FORM gui:createFormFromClass ?CLASS .
Currently one gets this exception when clicking on Tools / Snapshot of the user KB in N3 editor :

Ha ha, Jena grunts at this :

Apparently predicate should not be a blank node ! I'll have to change the Swing rule base. This was an attempt to make a ternary association. But I may have to change the Drools/N3 engine, because I'm not sure that matching lists really works with the Drools/N3 engine.
I'll have to think about this when I refactor the Swing rule base.
you need to put in .xinitrc this two lines

The hypothesis is now that the thread to watch URI modifications interferes with normal project download.
A remedy could be to postpone the thread to watch URI modifications by an arbitray time, or , even better, to deactivate until normal project download is over.

There is flexibility for deployment of an EG runtime.
Here are the options for the pure expert system part ( business rules + possibly some RDFS + OWL generic rules ).
Now for database access here are the options:
And for user interface generation here are the options. This is very promising, but it's work in progress.
we are finishing the new architecture for embedding Java objects in KB, so that they are activable by rules.
N3ConversionRefesher now has a field updateDroolsRuleBase ( false by default) to enable dynamic addition of rules ;
tested in a empty BasicRuntime :
==> { :a :a :a } => { :b :b :b } . ==> :a :a :a . ==> :b ?X ?Y .
PENDING:
There is a problem with N3 source from string, in the N3 shell, when the same URI is re-used; the compilationTimestamps Map in N3toDroolsUpdater is set the first time; then getTimeStamp() returns 0, so outdated() returns false.
As a consequence the new line in the shell in not processed.

Re-working on the N3 shell :) .
The N3 shell is a laboratory for exploring application generation , generally N3 <--> Java interaction , and other stuff. These extensions are planned :
* integrate in the GUI, probably in a tab
* keep all N3 input from user in an N3 file
* have commands for actions in EulerGUI: open N3 source, launch inference engine X, etc
% cat ~/bin/n3shell java -cp $HOME/.m2/repository/eulergui/eulergui/1.8-SNAPSHOT/eulergui-1.8-SNAPSHOT-jar-with-dependencies.jar deductions.runtime.BasicRuntime $* % n3shell examples/java_gen.n3p
Enter N3 / RDF triples, or queries like: :x ?P ?O . , line by line; empty line to stop.
Bound prefixes: [:, e:, java:, javam:, os:, owl:, rdfs:, xsd:, :, java:, javam:]
:x a java:javax-swing-JFrame . :x javam:setVisible ( true ) .
Something is missing in N3 - Java mix: this should instantiate and display the window. This happens through rules, but not through plain triples like here :( .
Thinking more, this cannot be by default in EulerGUI; otherwise any Java triples in any of the N3 sources will trigger lots of Java calls right on opening the project !
:x pimo:attendee :a , :b . ?A foaf:knows ?B .

I'm trying something not so trivial:
when network is not reachable the remote N3 sources are shown as buttons ; download later when network is reachable again;
generally I try to make a few things more robust before release ...
<rszeno> this is where caching is a good thing, :)
well, there is no file caching now for downloaded things ; except for really long things : compiled Drools rule bases; "compiled" XSD 's .
There is already a loop in a background thread that checks file or URL timestamp every 0.5 s ; I leverage on that.
However there is a cache , for ownloaded things, for the duration of the session.

COMMIT: rules-documentor.n3 : enhance : when ones documents a property, the output containing a skeleton documetation becomes empty .
There is a rule base that acts as a helper for documenting a rule base. Here a how-to. We may later add a button to facilitate that even more in EulerGUI.
First create an EulerGUI project with all the rules URI's you want to document, plus rules-documentor.n3 rules and as a query rules-documentorQ.n3 . This can be done e.g. by such a command line :
% eulergui generic_gui_projection-rules.n3 generic_to_java-rules.n3 rules-documentor.n3 --query rules-documentorQ.n3
A project containing all the rules you want to document can also be imported as a subproject.
Then click on Tools / Add all referred ontologies; this way you retrieve all definitions of properties and classes for the used prefixes.
Then you run the project with Euler ; this is very quick :
#ENDS 140 [msec] TC=136 TP=544 BC=0 BP=223 PM=0 CM=0 FM=0 AM=0
Look at the output of the inference: every Property that has no
documentation, at least with rdfs:comment
will appear. Now click
on the second yellow button on the top right; you'll see that every
undocumented RDF Property has gotten a skeleton documentation like this :
app:hasWindow a rdf:Property ; rdfs:comment "???" ; rdfs:domain "???" ; rdfs:label "???" ; rdfs:range "???" . |
The next step is to save this output of the inference in a non temporary
file, and add it to the project. Then, of course, you have to complete by hand
the "???" strings, and URI's for RDFS label and range. You should also change
rdf:Property into owl:DatatypeProperty
or
owl:DatatypeProperty
, as appropriate.
Then, for a check, you can re-run the project with Euler; every Property
that has been completed by hand, at least with rdfs:comment
, will
not appear in the output.
And the cool thing with that is: N3 rules (rules-documentor.n3) process N3 rules to create N3 output !
To think more: how to design an RDF graph for Simulation data along these lines ?
:s a :SimulationSpecification ; rdfs:label "Simulation of multiple pendulum" ; :gravitation "9.81" ; simulationEngine <http://ptolemy.eecs.berkeley.edu/> . |
Idea: build the equivalent of Spring configuration in N3.

Let's drink to rules, which will rule the world ! Another play on words: I went this summer to a school on CHR, and there I got a bag saying : "make your own rules".
temporarily unactivate TestEulerGUIInputs . testXMLInputGloze() , pending correction of N3 parser's NPE regression
This is a vicious consequence of new N3 format stuff, that also gets activated with ordinary .n3p format, due to the fact that ApplicationKB is a Project listener , and has rules to add things to the project. That could even lead to infinite loops !

Luc has corrected the triple order issue, so I continue testing embedded Java objects :) .
ERROR in running Drools Inference EngineCause:org.drools.RuntimeDroolsException: Exception executing predicate reference.ID == 1005 64 |
The issue is that Drools does NOT take in account the class criterium below, so its stops on ID property , when the first object is inserted in the Working Memory.
rule "java_event-rules.n3 0" when ... Assignment( $JEVENT : name, reference.class == java.awt.Event, $JEVENT_reference : reference ) Assignment( name == $JEVENT, reference == $JEVENT_reference, reference.ID == 1005 ) ... |
I tried to add methods equals() and hashCode() in class Assignment, so that Droools should know that these two object criteria refer to the same objects.
But no success!

I have a big problem with how eulergui.n3model.impl.< wbr>FormulaMutableImpl populates its field statementSet .
Tested with : deductions/n3_logical/java_< wbr>event-rules.n3
But the rule is :
{ |
The stack :
At this URI :
http://eulersharp.sourceforge.net/2003/03swap/log-rules#
there is this prefix declaration :
@prefix e: <log-rules#> .
I think that this really means :
@prefix e: <http://eulersharp.sourceforge.net/2003/03swap/log-rules#> .
because the original URI is a relative URI, which is expanded with the base URI .
Indeed CWM says on the original URI :
# Base was: http://eulersharp.sourceforge.net/2003/03swap/log-rules
@prefix e: <#> .
We have this piece of code in class PrefixMap:
if (uriUtil.isRelativeUri(prefixUri)) { absoluteUri = baseUri + prefixUri; |
This is , alas, not so simple !
I searched a simple link explaning how base URI is computed , and how N3 prefixes are interpreted .
Well , I don't have to really understand in depth http://www.ietf.org/rfc/rfc1808.txt , there is a class URI with methods resolve() and relativize() that do the job !
So the right code is :
if (uriUtil.isRelativeUri(prefixUri)) { absoluteUri = new URI(baseUri).resolve(prefixUri).toString(); |
baseUri
was set by EG beforehand:
http://eulersharp.sourceforge.net/2003/03swap/log-rules#
and prefixUri
is: log-rules# .
So absoluteUri
is computed to be just equal to
baseUri
in this case.
I fixed reading new N3 projects like newproject.n3p.n3), now fixing writing.
There are some subtleties. The example has typical triples like this:
<> owl:imports <book.n3> .
But it could be like this with the explicit project's URI:
<file:/home/jmv/myProj.n3p.n3> owl:imports <book.n3> .
Anyway, the internal KB has triples like this, because it can host several EulerGUI projects , and the internal KB must distinguish them.
Now, when user says "Save as ... (new format)" , under say
myNewProj.n3p.n3
, EulerGUI should take all triples :
<file:/home/jmv/myProj.n3p.n3> ?P ?O . ?O ?PO ?OO .
and save them as :
<file:/home/jmv/myNewProj.n3p.n3> ?P ?O . ?O ?PO ?OO .
Note that we don't need all the transitive closure from the project's URI, given the kind of triples that new N3 format for EulerGUI project contains .
Due to a bad update on W$ on Samsung phones, the phone does not boot anymore, and costumers are obliged to exchange the phone !
Pave the way for Subprojects with N3 format for EulerGUI project: harmonize properties Uri and Location in class Project.
The current issue is not when there is one N3 source with :isActivated
false
, all N3 sources become also unactivated. This rule seems to fire
when it should not :
{ # r2
?N3S a java:eulergui-project-N3Source .
?N3S java:URI ?IMPORT_URI .
?IMPORT log:uri ?IMPORT_URI .
?IMPORT :isActivated ?ACTIV .
} => {
?N3S java:activated ?ACTIV .
}.
|
The cause of this is : log:uri does not take in account that ?IMPORT_URI is
bound and ?IMPORT is not. So a single triple ?IMPORT :isActivated ?ACTIV
.
is enough to trigger the rule for any N3 source.
Remedies:
?N3S a java:eulergui-project-N3Source . ?N3S java:URIAsN3 ?IMPORT . ?IMPORT :isActivated ?ACTIV . |
string:concatenation
(not implemented at the moment)log:uri
so that it takes in account that object is
bound Solution 1 is the quickest to implement, and also makes for a shorter rule.
Another issue is that when there is a <> URI for the project, it does not allow to distinguish several project in a the (shared) internal KB. Happily , a listener corrects that after the inference :
Unité d'exécution [main] (Suspendue) ApplicationKB.add_project_n3_imports(Project, String) ligne : 218 ApplicationKB.n3SourceAdded(Project, N3Source) ligne : 201 ApplicationKB.projectLoaded(Project) ligne : 278 ProjectChangeSupport.fireProjectLoaded(Project) ligne : 95 Project.prepare() ligne : 1208 ProjectFactory.prepareProject(Project, URL, boolean) ligne : 271 ProjectFactory.restoreN3P(File) ligne : 244 ProjectFactory.restoreAny(File, boolean) ligne : 324 ProjectFactory.restore(String, boolean) ligne : 57 ProjectGUI.main(String[]) ligne : 188 |
This KB content seems correct, except that the Project's URI is not set:

BIG COMMIT: N3 format for EG project: WIP: added DeferredPropertyAssignment
Tested with examples/BloodPressure.n3p.n3
TODO : test suite, test examples/newproject.n3p.n3.owl ; clean new code
TODO
I've got a solution to a long time problem with N3 + Java cohabitation.
In the case of a Java object coming from another rule, a Drools rule that says: "when there is a deferred property assignment ?X ?P ?V , and ?X is a Java object, then make the property assignment and delete the deferred property assignment".
Note that this will actually simplify N3 to Drools translation, because this will work in both cases: is the Java object has been declared or not.
Note that this could be expressed in N3 or in Drools language.
Is this also the case for user callback binding ?
It could be with pre-procesising by Euler engine, if we could get the rule from the rule number.

After questions by <rszeno>
What is an implicit button?
An implicit button is a button that is inferred by the GUI generator e.g. from an OWL object property, where button action launches a new few form.
Can I add an explicit button ?
Here is the kind of N3 to put in a consequent side of a rule :
?BUTTON_id1 a gengui:Button . ?CONTAINER gui:components ?BUTTON_id1 . |
How does the multi-platform GUI generation work?
When a generic Button is created, it is qualified as a platform specific component by a simple rule, e.g. for Java:
{ ?W a gengui:Button. javapr:thisApplication app:platform app:Java } => { ?W a java:javax_swing_JButton } . |
Can I add a callback to a button ?
We are working on this.
Any widget (aka component) , Button or other, implicit or explicit, is
accessible by the framework through its URI. The component specific URI is
derived from the N3 variable , e.g. ?BUTTON_id1
above.
The runtime framework maintains a a multimap of all generated components keyed by URI's and component types. Using an N3 vocabulary, the developer can bind a callback class she has writen to the component URI ( TODO specify ). Then, at runtime, the framework binds the associated callback class (if any) to the newly instanciated component.
For example in Java, MyListener is a plain Java class implementing ActionListener that is associated to URI associated to N3 variable ?BUTTON_id1 . The runtime framework will call :
BUTTON_id1-instance . addActionListener (MyListener )
whenever a ?BUTTON_id1 is created through the rule.
Can I add validation to a input when user loses focus?
We are also working on this. Basically a business rule with false in the consequent side should be enough. However this does not provide any explanation to the user. So we had this in the very version of the framework, where the GUI events are managed by Java code and not by N3 rules. In project deductions/n3/test_person.n3p , we have this in person-events.n3 :
{ ?P a :Person . ?P :name "bush" . } => { ded:exception :throw " is already retired!" . } . |
This is interpreted by the Java driver (runtime framework ) so that it shows a popup window and refuses the user input when it's "bush" .
To make this work, in tools, click on "JavaScript console, OLD ARCH." , after a Drools inference.
We should re-establish this in the latest framework version, as hooks for arbitrary Java code (see callback to a button question).
Can I have datatype validation in input fields?
This worked in some old version of EulerGUI , also with "JavaScript console, OLD ARCH.". It should refuse a non-number when the range of the property is a Number.
We should re-establish this in the latest framework version, as hooks for arbitrary Java code (see callback to a button question).

1 | Maybe related to my Revision 2097
Modified Wed Feb 9 17:42:51 2011 UTC (44 hours, 30 minutes ago) by jmvanel Basic Runtime with a command line N3 interface ( class BasicRuntime ): - adding queries like: :x ?P ?O . - also FIX in N3Source when given by N3 string and URI: URI was lost - TODO : issues with default namespace in queries ==> in fact clearing the cache was enough (because due to this modification the URI of the search has changed) |
These are the stacks I copied in an error popup during TestSwingGeneration . test_person_import () :

My idea is that is due to several threads acting in parallel, the Java socket layer is lost.
This is coherent with these facts:
Currently we have Threads in all these classes:
% grep -l --recursive Thread src/main/java/**/*.java src/main/java/eulergui/drools_engine/ParserLink.java src/main/java/eulergui/gui/view/TextEditor.java src/main/java/eulergui/infrastructure/cache/URICacheOSCache.java src/main/java/eulergui/infrastructure/URIModificationChecker.java src/main/java/eulergui/inputs/N3SourceFromOtherFormat.java src/main/java/eulergui/inputs/N3SourceFromXMI.java src/main/java/eulergui/project/N3Source.java src/main/java/eulergui/tools/SWRLTranslator.java src/main/java/n3_project/ConsoleFrame.java src/main/java/n3_project/helpers/CoddHelper.java src/main/java/n3_project/ProjectFileManagement.java src/main/java/n3_project/RDFToN3Converter.java src/main/java/org/gjt/sp/jedit/jEdit.java src/main/java/unif/TemporaryFrame.java |
and we have synchronizedblocks in different areas :
grep -l --recursive synchronized src/main/java/**/*.java src/main/java/eulergui/infrastructure/cache/URICacheImpl.java src/main/java/eulergui/infrastructure/cache/URICacheOSCache.java src/main/java/eulergui/infrastructure/URIModificationChecker.java src/main/java/eulergui/inputs/JavaToN3Converter.java src/main/java/eulergui/n3model/impl/StringUriType.java src/main/java/eulergui/project/ProjectChangeSupport.java src/main/java/eulergui/project/ProjectFactory.java src/main/java/n3_project/IOManager.java src/main/java/n3_project/OWLToN3Converter.java src/main/java/n3_project/RDFToN3Converter.java src/main/java/org/gjt/sp/jedit/jEdit.java |
In summary, my feeling is that the new inference execution thread must wait that all HTTP downloads , and local translations (not always cached) are finished.
Note that only local translations to N3 from XML are always cached, not the rest like RDF/OWL.

Cyril suggest that some components can be out of the window size ...
Or there can be troubles in one of the servers ...
Another trouble is that Xephyr and/or fluxbox disappears in the middle of tests without any message. For the latter thing I try to remove -terminate argument to Xephyr
Cyril will add a callback for the end of inference , that will be leveraged , so that tests duration will go down from 16 to 10 minutes.

In jEdit Options / shortcuts, I changed the keys for "Complete Word" , and set it to Control Space (initially Control b) ; this is the same feature as Control P in gvim, and Control Space in eclipse.
I also changed "Line comment"

doing an exercise with EG: tackling the POM ==> DOAP conversion. So I started with project in deductions/transforms/ ; added a doap: prefix that was completed by prefix.cc , opened http://usefulinc.com/ns/doap# in EG ; then launched OWL reasonner just to have a class tree.
Then adding a search for ?P a rdf:Property.
added http://prefix.cc/pom

Features
It is nice to hear EulerGUI is so rapidly developing!
Well, not as quick as I'd wish ; the list of planned features is huge :
http://eulergui.svn.sourceforge.net/viewvc/eulergui/trunk/eulergui/html/documentation.html#TODO
We need users and feedback!
I'm not only for rules, it's a general tool for semantic web; if I knew another I'd use it or extend it.
By Ruset; this works :
@prefix : <#> . :bob :said { :gigi :know :lucy . } . :charly :said { :lucy :know :gigi . } . @forAll :x, :y . { [] :said { :x :know :y . } . [] :said { :y :know :x . } . } => { :x :know-each-other :y . } . |
Ruset's attempt:
@prefix log: <http://www.w3.org/2000/10/swap/log#> . @prefix : <#> . :bob :said { :gigi :know :lucy . } . :charly :said { :lucy :know :gigi . } . { [] :said ?whatever . [] :said { ?x :know ?y . ?whatever log:includes { ?y :know ?x . } . } . } => { ?x :know-each-other ?y . } . |

Problems with oneOf
Currently this OWL axiom :
[] a owl:Class ; rdfs:subClassOf :rock-fan ; owl:intersectionOf (owl:Thing [ a owl:Restriction ; owl:onProperty :like ; owl:someValuesFrom [ a owl:Class ; owl:oneOf (:Jimi_Hendrix) ] ]) . |
gives this N3 rule :
{?VAR :like ?t16. ?t16 a ?e56. ?VAR a owl:Thing} => {?VAR a :rock-fan}. # BAD
DIAGNOSTIC:
When the object of owl:someValuesFrom were a class URI, it works. The rule currently is:
{ # someValuesFrom Restriction ( ?ORIGINAL ?CLASS ?VAR ?Z) :owlClassExpressionHasFormula ?FORMULA . ?CLASS a owl:Restriction; owl:someValuesFrom ?VALUES_CLASS; owl:onProperty ?PROP . ?V e:tuple ?CLASS. } => { ?FORMULA :includes { ?VAR ?PROP ?V. ?V a ?VALUES_CLASS }. }. |
There must be a way to generate a class membership test from a class URI. When the class URI is an explicit class, the above rule in green works. But for more complex class definitions, I must invent something ...
I'm trying to take inspiration from http://www.w3.org/TR/rif-owl-rl/ to enhance my OWL -> N3 rules translation.
I'm trying to learn RIf , just to understand the OWL RL rules given in rif-owl-rl .

After some correction, the result is not wrong from a logical point of view, but not good enough :
{?t0 a ns1:Anjou. ?t1 a ns1:Anjou. ?t2 a ns1:Anjou. ?t3 a ns1:Anjou } => { ?t0 ns1:hasFlavor ns1:Delicate. ?t1 ns1:hasSugar ns1:OffDry. ?t2 ns1:hasColor ns1:Rose. ?t3 ns1:hasBody ns1:Light}. |
It should be:
{ ?t0 a ns1:Anjou. } => { ?t0 ns1:hasFlavor ns1:Delicate; ns1:hasSugar ns1:OffDry; ns1:hasColor ns1:Rose; ns1:hasBody ns1:Light }. |
It may be due to this at line 43:
?VAR e:tuple (?SUBCLASS rdfs:subClassOf ?SUPERCLASS).
By this I hope that everytime this appears in an antecedent , the same ?VAR is retrieved. In fact it was just "called" once, but caling it where needed does not change anything.
I follow advice by Jos in march28 2010:
After a correction in euler.yap you can now use free variables (*) for this purpose:
@prefix : <http://test.com#>.
@prefix e: <http://eulersharp.sourceforge.net/2003/03swap/log-rules#> .
@prefix log: <http://www.w3.org/2000/10/swap/log#> .

?SCOPE e:findall ({var:V a ?C} {?C list:in ?CC} ?CRITS0).
?CRITS0 log:conjunction ?CRITS.
} => {
?CRITS => {var:V :consequence :inferred}.
}.
(*) free variable are not quantified with @forSome or @forAll and for euler they live in <http://localhost/var#>

I'm translating directly OWL subclass assertions into N3 rules , using N3 rules:
http://deductions.svn.sourceforge.net/viewvc/deductions/n3_new/owl-subclass-assertions-to-rules.n3
I have this rule :
{ # minCardinality Restriction ( ?ORIGINAL ?CLASS ?VAR ?Z) :owlClassExpressionHasFormula ?FORMULA . ?CLASS a owl:Restriction; owl:minCardinality ?MIN; owl:onProperty ?PROP . ?V e:tuple ?CLASS. ?Y e:tuple (?CLASS). } => { ?FORMULA :includes { _:d e:findall (?V {?VAR ?PROP ?V} ?Y). ?Y math:memberCount ?C. ?C math:notLessThan ?MIN }. }. |
and I'm tempted to copy and paste it with 2 modifications :
{ # maxCardinality Restriction ( ?ORIGINAL ?CLASS ?VAR ?Z) :owlClassExpressionHasFormula ?FORMULA . ?CLASS a owl:Restriction; owl:maxCardinality ?MIN; owl:onProperty ?PROP . ?V e:tuple ?CLASS. ?Y e:tuple (?CLASS). } => { ?FORMULA :includes { _:d e:findall (?V {?VAR ?PROP ?V} ?Y). ?Y math:memberCount ?C. ?C math:notGreaterThan ?MIN }. }. |
What better can I do ?
I first thought of factoring the common part in antecedent:
{ # maxCardinality Restriction ( ?ORIGINAL ?CLASS ?VAR ?Z) :owlClassExpressionHasFormula ?FORMULA . ?CLASS a owl:Restriction; ?RESTRICTION ?MIN; owl:onProperty ?PROP . ?V e:tuple ?CLASS. ?Y e:tuple (?CLASS). } => { ?FORMULA :formulaForRestriction ( ?VAR ?PROP ?RESTRICTION ?MIN ). }. |
But this has the inconvenient of only acting on the antecedent. So I thought of parametrizing the part that differs in both rules, and - guess what ? It works !
owl:minCardinality :hasOperator math:notLessThan. owl:maxCardinality :hasOperator math:notGreaterThan. { # maxCardinality Restriction ( ?ORIGINAL ?CLASS ?VAR ?Z) :owlClassExpressionHasFormula ?FORMULA . ?CLASS a owl:Restriction; ?CardinalityProperty ?NUMBER; owl:onProperty ?PROP . ?V e:tuple ?CLASS. ?Y e:tuple (?CLASS). ?CardinalityProperty :hasOperator ?OPERATOR. } => { ?FORMULA :includes { _:d e:findall (?V {?VAR ?PROP ?V} ?Y). ?Y math:memberCount ?C. ?C ?OPERATOR ?NUMBER }. }. |
Now there is yet another group of three Object Property Restrictions, the qualified ones, e.g. :
_:x rdf:type owl:Restriction. _:x owl:onProperty P. _:x owl:qualifiedCardinality n. _:x owl:onClass C. |

As a side note, it's now possible to enter Euler/EYE arguments in EulerGUI command line arguments; a project will be created (but not saved) :
eulergui --nope --quiet --quick-possible \ http://eulersharp.sourceforge.net/2007/07test/alpP001.n3 \ http://eulersharp.sourceforge.net/2007/07test/alpA010.n3 \ --query http://eulersharp.sourceforge.net/2007/07test/alpQ001.n3 |
In this example the project name will be alpP001.n3.n3p .
In the following output , ones sees that possible models compatible with the inputs and query are listed, as well as one counter Model.
[ e:possibleModel {:Peter :ascribed :smokes} ; r:gives { :Peter :ascribed :wheezing. } ]. [ e:counterModel {:Peter :ascribed :nonsmoker} ]. [ e:possibleModel {:Peter :ascribed :influenza} ; r:gives { :Peter :ascribed :wheezing. } ]. |
It seems that all examples with possible model also have e:disjunction in them.
Tomorrow , I'll try to reason with possible models with Euler, with an OWL ontology, and
_:x a SomeClass .
to see if Euler can infer
_:x _:someProp _:y .

commited:
- Feature: before launching Euler / EYE, expand Arguments entered in the input field
TESTED with test/BloodPressure.n3p
- add a key listener in TextFieldWithLabel , so that when the project is saved, the fields Euler and CWM arguments are also saved

TODO : continue
I'm thinking about using Euler for generating the Drools code.
One of the problems is generating the variable declarations.
From the rules, ones extracts a list of variable references, like:
( ?X ?Y ?X )
To each variable reference, one must associate :declaration if it is the first use, and :use otherwise.
( :declaration :declaration :use )
The condition for :declaration is : "the list of variable before current variable with the same id is empty" .
For this I need a predicate to output the list of sub-elements preceding an element :
:sublistBefore a rdf:Property. ( (:a :b :c :d :e) :c ) :sublistBefore ( :a :b ).
I could probably define this with 2 recursions, one for the begining of list, and another for the end, but I tried this :
{ ( ?L1 (?ELEM) ?L2) list:concatenation ?LIST . } => { (?LIST ?ELEM) :sublistBefore ?L1 . } . |
Alas, I tried with --pass , and also with a query ; anyway it loops forever.
Solution from Jos: add ?LIST a rdf:List
in the antecedent
.
Begining of a solution by recursion, without any builtin:
@forAll ?X. ( () ?X ) :sublistBefore (). @forAll ?X , ?W . ( (?W ?X) ?X ) :sublistBefore (?W). |
flatten-rules.n3 : WIP : wonder if it's right way to go for flatening N3 rules:
- hard to avoid that flatening rules are processed by themselves
( currently rules with notEqual are skipped )
- maybe do it in a single big rule
- can still do it in Java with TripleHelper
- TODO: for Drools generation, generate declarations when meeting a variable for the first time
announce on jEdit

Reminder:
EulerGUI is a GUI for N3 / RDF and rules, centered on the N3 language. It is Open Source, written in Java Swing.
N3 is a human readable language for RDF, OWL, and rules. It is used by many tools (including Protégé); N3 rules look like the query language SPARQL.
EulerGUI has an N3 textual editor, with syntax coloring, tooltips on terms based on rdfs:label and rdfs:comment. This N3 editor is reusing the famous jEdit editor.
EulerGUI includes SPARQL queries, Pellet OWL reasoner, Graphviz diagram, etc.
It has importers for OWL+SWRL ontologies, plain XML, etc.
It can launch several N3 logic engines.
For Protégé users, the main new features are:
- Read an OWL/XML document; from a file XXX.xml, XXX.owl, or from an URL;
- when an OWL, RDF, XML, XMI file is modified on disk by Protégé, it is re-loaded and re-translated automatically to N3 within EulerGUI
This allows to enter OWL + SWRL in Protégé 4.1 or older, and run the SWRL rules in the EulerGUI window, by just clicking a button in EulerGUI.

I was based on this Revision :

Today, http://www.w3.org/DesignIssues/N3Logic.html says:

$Revision: 1.19 $ of $Date: 2012-03-09$
The version commited in eulergui :

This old HTML formatting is bad , and I can't remember how I made it.
The version sent to Tim Berners-Lee :

And a version downloaded from W3C 3 days ago :

Status: An early draft of a semi-formal semantics of the N3

</address>
Now diffing my version passed in Tidy with the latest Tim version gives this :
1a2,3 > <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" > "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 5c7 < "HTML Tidy for Mac OS X (vers 31 October 2006 - Apple Inc. build 13), see www.w3.org" /> --- > "HTML Tidy for Linux (vers 25 March 2009), see www.w3.org" /> 8,10c10 < <title> < Notation 3 Logic < </title> --- > <title>Notation 3 Logic</title>
So the real issue is that the two tidy versions differ in formatting.
For now, I'll commit this version.
I tried a smart thing. I pass Time latest version in my Linux version of Tidy :
tidy -asxml N3Logic.html > N3Logic_tidy.html
Now the diff gets much better!
COMMITED:
Enhanced N3Logic.html (my corrections to DesignIssues/N3Logic by Tim Berners-Lee)
The old HTML formatting was bad , and I can't remember how I made it.
I took the version that I mailed to timbl on 19 feb. 2010 17:08 ,
and applied to it tidy -asxml
Now the diff with current timbl's version on W3C gets much better,
provided that I also apply tidy -asxml to timbl's version;
this is because he used
HTML Tidy for Mac OS X (vers 31 October 2006 - Apple Inc. build 13), see www.w3.org"
and I use
HTML Tidy for Linux (vers 25 March 2009)

<jmv_> Besides RIF_In_RDF http://www.w3.org/2005/rules/wiki/RIF_In_RDF , is there another RDF vocab for rules ?
RIF:
rule raise_rate { when { a: Account(r: rate; r > 1; r < 2); } then { modify a { rate = 2; } } } |
N3 equivalent in EulerGUI:
{ a1 a Account; rate ?r. ?r math:greaterThan 1; math:lessThan 2 . } => { -:d kb:replaceValue ( a1 rate 1 2 ) . } |
Thinking of writing a rule-based generic compiler for RETE engines.
Using @cygri's nice and useful http://prefix.cc Web service for filling missing N3 prefixes when saving files in EulerGUI
Searching people knowledgeable in rule engines and/or logic programming
I had a look at RIF_In_RDF http://www.w3.org/2005/rules/wiki/RIF_In_RDF ; I think the mapping should be done like Gloze does. (mail to Sandro )

I actually have rules in N3 to transform SWRL into N3

Abstract
This document specifies a reversible mapping (or transformation) from Rule Interchange Format (RIF) XML documents to Resource Description Framework (RDF) graphs. This mapping allows the contents of RIF documents to be interoperably stored and processed as RDF triples, using existing serializations and tools for RDF. When used with the standard mapping from RDF triples to RIF frames, this also provides a "reflection" or "introspection" mechanism, an interoperable way for RIF rules to operate on RIF documents.
The N3 is translated 3 times into Drools :

- Prefix was wrong : http://www.w3.org/2005/xpath-functions
- added tests in math.n3 for:
- process statically created lists in e:max , e:min
- process dynamically created lists in math:sum, etc
I wonder if automatic retract works for Collections, e.g. :
when $c : Customer( totalsOrders > 100000 ) then $list.add( $c )
Well, it can't, as for automatic retract , an insertLogical() is to be used, and we have no addLogical() for Collections.
This will do automatic retract :
when $c : Customer( totalsOrders > 100000 ) then insertLogical(new Display( $c, $goodCustomersPanel ) )
But the question : how to have a GUI display of the Display objects without too much ad-hoc code ?
The solution I see is to have Drools query for the Display objets , launch this query at every firing of rules, and re-populate the GUI with the result of the query.
On swig IRC :
<jmv_> Any idea of an ontology for units and physical elements like mass, length, temperature ... maybe as properties on DataType Properties, or classes Unit and Measurement ?
<tobyink> jmv_: take a look at http://forge.morfeo-project.org/wiki_en/index.php/Units_of_measurement_ontology
<tobyink> However, it uses the http://esw.w3.org/InterpretationProperties antipattern.
<tobyink> i.e. it models things like this: <#me> :height [ :value 178 ; :unit :centimetres ] .
<tobyink> whereas it's better to model things like this: <#me> :height [ :centimetres 178 ] .
<tobyink> or even: <#me> :height "178"^^:centimetres .

Project : for subprojects, during Drools runs, the argument useInsertLogical was not passed,
which caused functional tests TestGenericGuiGeneration and TestSwingGeneration to fail
(they require useInsertLogical == false , which is not the default anymore )

Removed this in Project's comments
* For Euler SEM reasoner, We would like to reuse the same rules and facts
* compiled in Prolog for several queries, but this is not currently possible in
* Euler due to 2 problems. There is a problem when translating in Prolog the
* query alone: no query on output.
* <p/>
* A 2nd problem is with the namespace prefix renaming that could be the case in
* the query file, so the transaction approach is the only feasible one at the
* moment.

DONE
Now the GUI for pricing appears in EulerGUI
- add query2.n3 (it is already in the subproject, but there is a bug in EulerGUI right now )
Form generation examples, like deductions/samples/pricing/pricing-gui.n3p , give a correct (but simple) result.
Implement sum rule; syntax correct with CWM, Euler and Parser4J/N3 , e.g. :
eye --pass --nope pricing.n3
With useInsertLogical == true in EulerGUI , the test suite seems without error or failure but it says :
Tests run: 128, Failures: 0, Errors: 0, Skipped: 0 [INFO] ------------------------------------------------------------------------ [ERROR] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] There are test failures.

With useInsertLogical == false in EulerGUI :
Running eulergui.gui.TestGenericGuiGeneration Tests run: 8, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 176.882 sec <<< FAILURE!
CONCLUSION: TODO:
We must debug the form generation rule base in swing-rules3.n3p . There are 2 different problems: 1) infinite loop 2) pricing-gui.n3p gives an empty result, due to main query from subproject not taken in account . This is also the oportunity to enhance debugging tools.
In fact the problem was not "main query from subproject not taken in account", it was in doing "Save as"; the subproject's query was saved in the main project.

I added this update source:
babel R0.8.0 helios - http://download.eclipse.org/technology/babel/update-site/R0.8.0/helios
I works fine, but at the same time I had a hardware crash when restarting eclipse, so I lost my workspace, but not my projects.
- FIXED Infinite loops in Drools inference: hard-coded useInsertLogical = true and false was remaining
in N3SourceToDrools and N3SourceUpdater
- added a missing I18 string
#TRACE ( ">>>> starting createFormFromResource: " _:sk_FORM_33 <http://eulergui.sf.net/example#creamTart> ) #TRACE ( " " _:sk_WINDOW_32 <http://eulergui.sf.net/example#Mobile> ) #TRACE ( ">>>> createFormFromResource: " _:sk_FORM_33 <http://eulergui.sf.net/example#creamTart> <http://eulergui.sf.net/example#Mobile> ) #TRACE ( "generic_gui_projection 5" _:sk_FORM_33 "javapr:projection" _:sk_JPANEL_FORM_34 ) log:notEqualTo RT : <http://www.w3.org/2002/07/owl#Thing> <http://eulergui.sf.net/example#Mobile> #TRACE ( "3" <http://eulergui.sf.net/example#Mobile> <http://jmvanel.free.fr/ontology/gui_generic.owl#hasForm> _:sk_FORM_33 ) |
Changing this in Project.doTranslateN32Drools() solves the problem :
// getTranslator().translate( n3, useInsertLogical ); TODO test <<<<<<<<<<<<<<<<<<<<<< getTranslator().translate( n3 );
This could mean that the rule base for form generation is still not clean enough to work with insertLogical.
Or the parameter useInsertLogical
is not transmitted
correctly.
With the old line translate( n3 )
, this test runs forever :
eulergui.gui.TestGenericGuiGeneration
but the other 2 TestXXXGeneration run fine.
In fact a hard-coded useInsertLogical = true was remaining somewhere :(((
That solves the problem ! :((

- REGRESSION FIXED: N3 sources' URI broken for a Web subproject of a file project:
- also changes in ProjectFactory.prepareN3Sources() : only call prepare on Direct N3 Sources and direct N3 Query
TODO: is ProjectFactory.prepareN3Sources() useful at all ?
- clean unused imports
The other problem is in this stack :

At this point the N3Source has a bad location: file:/home/jmv/src/eulergui_new/examples/software_applications.n3
within Project file:/home/jmv/src/eulergui_new/examples/acceleration_form.n3p
Thread [AWT-EventQueue-0] (Suspended (breakpoint at line 831 in Project)) Project.doTranslateN32Drools(boolean) line: 831 Project.translateN32Drools(boolean) line: 779 Project.prepareDrools(boolean) line: 759 Project.doRunDrools(boolean) line: 715 Project.runDroolsTriples(List<ITriple>) line: 670 Project.runDroolsTriples(boolean) line: 664 RunDroolsAction.actionPerformed(ActionEvent) line: 48 JToolBar$1(AbstractButton).fireActionPerformed(ActionEvent) line: 1995 |
In fact the N3Source inside the subproject
http://deductions.svn.sourceforge.net/viewvc/deductions/n3_logical/swing-rules3.n3p
already have this bad location.
This probably happens during ProjectFatory.restore() .
Adding this breakpoint in Project.addN3Source(N3Source n3, boolean isTransient)
n3.getLocation().toString().contains( "form-rules.n3" ) |
And this at the begining of N3Source.getLocation() :
( location != null && location.toString().contains( "form-rules.n3" ) ) || ( uri_ != null && uri_.toString().contains( "form-rules.n3" ) ) |
Now I'm here for :
http://deductions.svn.sourceforge.net/viewvc/deductions/n3_logical/form-rules.n3
those project is the correct one :
http://deductions.svn.sourceforge.net/viewvc/deductions/n3_logical/swing-rules3.n3p

FEATURE TODO
prefix.cc is useful: from this kind of URL one gets ( with N3 content type) :
http://prefix.cc/foaf,dc,owl.file.n3
@prefix foaf: <http://xmlns.com/foaf/0.1/> . @prefix dc: <http://purl.org/dc/terms/> . @prefix owl: <http://www.w3.org/2002/07/owl#> .
By entering somehow "foaf" in the GUI, the @prefix declaration will be added in the editor.
At the same time, the ontology (loaded from its URI) will be added to the project as a transient N3 source.

A discussion on SWIG IRC:
Hi ! In the RDF GUI I'm developing, I need to have a list of well-known RDF/N3 prefixes with the URI of the ontology which defines the URI having the prefix; e.g. :
<http://xmlns.com/foaf/0.1/> eg:prefixOf <http://xmlns.com/foaf/spec/index.rdf> .
Any suggestion for the predicate eg:prefixOf ?
<kwijibo> eulergui-1.7_: see prefix.cc/vanni est parti (Read error: Connection reset by peer) <webr
<webr3> that's not realy a prefix foaf -> http://xmlns.com/foaf/0.1/ is a prefix, the mapping you've got there is one which changes over time
<webr3> http://xmlns.com/foaf/0.1/ <-- perma uri
-dc_swig/#swig- A: http://xmlns.com/foaf/0.1/ from webr3
<eulergui-1.7__> webr3, sounds good, but what would be permanent URI for http://xmlns.com/foaf/spec/index.rdf ?
<eulergui-1.7__> kwijibo, vann has good stuff ( and my family name is Vanel ;) ) ,et by peer) <webr
<eulergui-1.7__> but it lacksiation between a prefiw and the dereferentiable location of the ontolo the association between a prefiw and the dereferentiable location of the ontology .
<webr3> eulergui-1.7__, tbh this is to do with the way FOAF and DC are published and the URIs they use, for nearly every other ontology you don't have this problem, as they all use #frag properties
<jmv__> kwijibo, in the GUI we develop (EulerGUI), there tooltips showing rdf:label and rdf:comment about the term under the mouse ( in a N3 editor ).
<kwijibo> jmv__: so?
<jmv__> so when the user is editing for example a FOAF N3 document, it needs to find the ontology ,
<jmv__> and this should be done from an N3 configuration file
<kwijibo> jmv__: you can let your http client dereference it for you? what's the use-case for knowing what it derferences to in advance ?
<jmv__> thanks, kwijibo, vann indeed suits my purpose; however I don't understand what you don't understand about my use case ...
<kwijibo> jmv__: if you do a GET on http://xmlns.com/foaf/0.1/ (and follow the redirect), you get the URL of the document - why do you need to know anything other than the http://xmlns.com/foaf/0.1/ URI ?
<kwijibo> after all, it could change it every day
<kwijibo> (the spec.rdf URL )
<jmv__> kwijibo, alas if I do a GET on http://xmlns.com/foaf/0.1/ , at least in my browser, I get an HTML page saying : FOAF Vocabulary Specification 0.98
<jmv__> Namespace Document 9 August 2010 - Marco Polo Edition , etc
<kwijibo> jmv__: that's because you're not sending an accept: application/rdf+xml header
<kwijibo> (or rather, your browser isn't)
<jmv__> Maybe if I did by program an HTTP query with content negotiation, but in the most general case the prefix URI of an ontology is not enough to donwload its definition.
<kwijibo> yeah it is
<kwijibo> if a vocab namespace URI doesn't deref, with conneg, to RDF, it's not doing it right
<jmv__> I'd like that , but It's not garantied AFAIK
<kwijibo> I bet it's more reliable than a hard coded mapping
<kwijibo> which vocabs don't deref to RDF?
<jmv__> the hard coded mapping is just for the vocabs that don't do things right
<kwijibo> which ones are they?
<jmv__> I'll try to pick one , kwijibo :)
<jmv__> kwijibo, indeed that works fine :
wget --header=accept:application/rdf+xml http://xmlns.com/foaf/0.1/
<jmv__> after dinner I'll try many more .
<kwijibo> lol
Following advice by Keith Alexander on the SWIG IRC, I'm trying RDF download with HTTP header accept:application/rdf+xml , e.g. this works:
wget --header=accept:application/rdf+xml http://xmlns.com/foaf/0.1/
From the browser, http://xmlns.com/foaf/0.1/ returns the HTML man readable specification.
In the case of SIOC, the URI is the ontology definition, and the HTML man readable specification:
http://rdfs.org/sioc/spec/
only ever returns HTML, no matter what the HTTP header accept says.
TODO
configuration file: a N3 document with lines such as :
dcterms:creator rdfs:seeAlso http://purl.org/dc/terms/

- automatically save generated Drools source in case of error
- this rule in Jos' owl-rules.n3 did not pass Drools translator, because list related triples are processed together at the next non list related triple, and a single list related triple was not implemented

- add a version of owl-rules.n3 in examples/ ; just move log:notEqualTo at the end of the antecedent.
TODO
The problem is that the implementation of log:notEqualTo
expects that all variables were already used in preceding triples in same

This is not easy to implement with Drools. The translation should be postponed to end of the antecedent.

I'm thinking about using ATTEMPTO for speficying rules for RDF graph transforms.
Take for exemple these rules in the N3 rule langage [1] , that are part of a rule base [2] for transforming an UML model into an OWL model :
{?UML_CLASS a uml:Class . } => { ?OWL_CLASS a owl:Class .?OWL_CLASS :translatedFromUML ?UML_CLASS .} . { # transfer uml:name predicate to rdfs:label for Classes, properties, etc ?UML_CLASS uml:name ?NAME .?OWL_CLASS :translatedFromUML ?UML_CLASS . } => { ?OWL_CLASS rdfs:label ?NAME .} .
A naive verbalization of these 2 rules reads:
If UC is a uml-class then there is a owl-class OC, and OC is transtaled-from UC.
If UC has-uml-name N, and OC is transtaled-from UC then UC has-rds-label N.
This does not work directly, as "variable names consist of a single upper case letter, optionally followed by an integer".
If U is a uml-class then there is a owl-class O, and O is transtaled-from U.
If U has-uml-name N, and O is transtaled-from U then U has-rds-label N.
Note that the first can also be writen:
If U is a uml-class then there is a owl-class O, and O is translated-from U.
Now let's try that last one in ACE View:
SubClassOf( ObjectIntersectionOf( Class(owl:Thing) Class(:uml-class) ) ObjectSomeValuesFrom( ObjectInverseOf(ObjectProperty(:translated-from)) Class(:owl-class) ) )
This is perfectly sound logically, but we are quite far from a rule suitable for a forward chaining engine.
I look now at what the OWL N3 rules by Jos de Roo from the Euler project can do. I first generate the OWL+SWRL file :
./ape.exe -guess -text \ "If U is a uml-class then there is a owl-class O, and O is translated-from U. If U has-uml-name N, and O is transtaled-from U then U has-rds-label N." \ -solo owlxml > uml-owl.owl
Then I can open uml-owl.owl
in EulerGUI. The rule 1 (name
transmission rule) was an SWRL rule and is now become an N3 rule:
{?t0 ns1:has-uml-name ?t2. ?t1 ns1:transtaled-from ?t0} => {?t0 ns1:has-rds-label ?t2}.
No logical problem, but the identifiers were transformed from the original N3.
Now the other, pure OWL, sentence.
There are 35 OWL N3 rules by Jos de Roo from the Euler project :
~/src/eulersharp/2003/03swap/ % ls owl-*.n3 owl-AllDifferent.n3 owl-FunctionalProperty.n3 owl-propertyChainAxiom.n3 owl-AllDisjointClasses.n3 owl-hasKey.n3 owl-propertyDisjointWith.n3 owl-AllDisjointProperties.n3 owl-hasValue.n3 owl-rules-200.n3 owl-allValuesFrom.n3 owl-intersectionOf.n3 owl-rules-660.n3 owl-AsymmetricProperty.n3 owl-InverseFunctionalProperty.n3 owl-rules.n3 owl-complementOf.n3 owl-inverseOf.n3 owl-sameAs-ext.n3 owl-differentFrom.n3 owl-IrreflexiveProperty.n3 owl-sameAs.n3 owl-disjointUnionOf.n3 owl-maxCardinality.n3 owl-someValuesFrom.n3 owl-disjointWith.n3 owl-maxQualifiedCardinality.n3 owl-SymmetricProperty.n3 owl-distinctMembers.n3 owl-NegativePropertyAssertion.n3 owl-TransitiveProperty.n3 owl-equivalentClass.n3 owl-Nothing.n3 owl-unionOf.n3 owl-equivalentProperty.n3 owl-oneOf.n3 |
The owl-rules.n3 file gathers all the rules. We see that there are rules for all the OWL primitives used in our OWL expression (colored in green). So we add this URL to the EulerGUI project, together with a simple test data and query.
http://www.agfa.com/w3c/euler/owl-rules.n3
Alas with Euler, the result is empty, and Drools crashes :
java.lang.NullPointerException at n3_project.helpers.DroolsTripleHandler.processLogBuiltin(DroolsTripleHandler.java:378) at n3_project.helpers.DroolsTripleHandler.makeDroolsCriterium(DroolsTripleHandler.java:240) at n3_project.helpers.DroolsTripleHandler.acceptAntecedent(DroolsTripleHandler.java:207) at eulergui.drools_engine.ParserLink.visitAllURI(ParserLink.java:707) at n3_project.helpers.N3SourcetoDrools.translate(N3SourcetoDrools.java:266) at n3_project.helpers.N3SourcetoDrools.translate(N3SourcetoDrools.java:237) at n3_project.helpers.N3toDroolsUpdater.translate(N3toDroolsUpdater.java:88) at n3_project.helpers.N3toDroolsUpdater.translate(N3toDroolsUpdater.java:78) at eulergui.project.Project.doTranslateN32Drools(Project.java:829) |
The reason is that this rules is not translated correctly from N3 to Drools , that is, the rule owl-differentFrom.n3 :
{
?X <http://www.w3.org/2000/10/swap/log#notEqualTo> ?Y.
?A <http://www.w3.org/2002/07/owl#distinctMembers> ?L.

?L <http://eulersharp.sourceforge.net/2003/03swap/owl-rules#item> ?X.
} => {
?X <http://www.w3.org/2002/07/owl#differentFrom> ?Y.
} .
|
TODO
The problem is that the implementation of log:notEqualTo
expects that all variables were already used in preceding triples in same rule,
which is not the case for first triple here.
This is not easy to implement with Drools. The translation should be postponed to end of the antecedent.
Or I could ask Jos to change the rule :) .
DONE
- new class URIModificationChecker, that starts a loop to check Modification status of files and URL's, for all original sources, and then if modified call Project.fireN3SourceChanged(N3Source) , to refresh the N3 conversion
- the old mechanism with jEdit to get notifications of LOADED events for original source should be commented out and replaced with this one
TODO : more manual testing
I thought about implementing the processing of the N3 source in a lazy way with timestamp in doUpdate() for XML and XMI sources (so that the project opens more quickly), but it is more useful to have a generic file and URL modification checking service, so that N3 refreshing occurs even when the original source is not opened.
For the file and URL modification checking service, I saw that jEdit offers no service to reuse.
We would like to register a file to get its modifications events, even though it has not been opened by the user.

Raw Google translate
First thing, we must improve the current design and implementation of the Java engine + N3, based on Drools, as with N3 rules language, which is a unique combination of Semantic Web, rules engine, and the platform Java.Dans form the existing implementation, the translator N3 to Drools is a simple architecture that spits strings over water. We need something like a compilation technique driven by rules. And we would also generate rules Jena, Mercury code, Scala, CHR rules, etc.. I thought about using transformation rules in N3 N3 for input, and GF (GrammaticalFramework) for the release of the final string.
Second thing, we need to design and implement a backward chaining engine for querying databases SPARQL in the presence of business rules in N3. It will generate a large accumulation by recursive query SPARQL criteria, substitution variables, renaming variables if necessary. I think to this point 2, CHR capacity to manage the free variables can be used.
Another issue concerns the generation of user interfaces
from high level specifications, including ontologies
OWL, business rules in SWRL or N3, and other specifications
declarative user interaction.
Linked to this, a rule-based board would operate
history of user actions to infer their intentions,
and propose appropriate actions (good servant paradigm).
Finally, we apply the inference techniques for
semantic manipulation of existing software assets: guess
calling sequences from sample code, annotate
semantically libraries, classes and methods, generating code
join from semantic annotations (Modularity
intelligent).
First thing, we need to enhance the current design and implementation
of the Java + N3 engine, based on Drools, with N3 as rule language;
this is a unique combination of Semantic Web, rule engine, and Java
platform. There already something working, but that is a simplistic
architecture spitting strings along the way; we need something like a
compiler technique piloted by rules.
Second thing, we need to design and implement a backward engine for
querying SPARQL databases; it will generate a big SPARQL query by
recursively accumulating criterium terms, substituting bound
variables, renaming variables if necessary.
I think that for point 2, the capabilities of CHR to handle unbound
variables can be leveraged.
Another thema is generating user interfaces from high level specifications.
Still thinking about possible tasks for you .
Among the things we talked in the last months:
- cleaning ACE=>OWL by using Thea stuff
- verbalizing N3 and SWRL rules
- adding more of the OWL "semantyic sugar" like transitive properties,
equivalent classes, etc
Plus reusing in ACE URI's for classes and properties, which is
certainly on top priority.
Related to that is verbalization of some typical OWL ontologies; a
default verbalization of these ontologies and of instances by ACE
often looks bad, for lack of noun and verb forms.
A good test case is FOAF's official OWL spec. .
These is also the algebraic formulas.
By the way I'm worried about how the ACE as a whole is going. Still no
answer from Norbert and the team about the depot question, which is just
the first of a series of questions about gouvernance.
About my projects EulerGUI and Déductions, I must set a road map ;
this is larger than the CNL stuff, as we are building a whole
framework for building business and scientific applications. There are
several important things to do or enhance :
- mix in rules triples for domain data with Java objects , leveraging Drools
- at runtime query SPARQL sources taking in account rules in the KB
- generate easily all formats from RDF
DONE

- XmiInputAction : remove duplicated action of Translating To N3 the underlying XMI

- FEATURE: Jena view of the result (second yellow button) : add N3 prefixes

Reference: Jena 2 Inference support ; Jena JavaDoc ; EulerGUI JavaDoc (NEW!)
InfGraph ---|> Graph ---|> GraphAdd bound Reasonner <>------ InfGraph schema Reasonner <>------ Graph |
InfGraph is a Graph where Triples added by inference can be distinguished.
Each Reasoner implementation is associated to ReasonerFactory.
ReasonerFactory are registered in a singleton ReasonerRegistry.
Graph is on the SPI side (Service Provider Interface), while Model (a huge interface) is on the API side.
In EulerGUI this does not exist:
In EulerGUI this exists:
Project and N3Source are at the heart of EulerGUI. The accent is put on how to build a RDF + rules Model out of heterogeneous parts. In contrast in Jena the accent is put on the RDF Model itself, and once a source is added to the Model, this action of adding is forgotten.
About reasoner support, there are differences. In Jena, one can bind many reasoners of the same or different implementation to the same Graph, resulting in as many InfGraph objects. In EulerGUI, each different engine implementation is a unique service. A common feature is that different rule engines do not collaborate, each has its own augmented model.
Currently (alas) the glue code for the inference engines (alias reasoners) in EulerGUI is all in class Project. The first task is to modularize the inference engines support in EulerGUI. To this end, these hardships exist:
The first thing in modularizing the inference engines support in EulerGUI is to design an API to be used by the GUI layer. The possible inference engines should not be hard coded in the class Project, but offered as a uniform list of services. The minimal capabilities expected from an inference engine instance (already bound to a Project) are in this interface :
public interface InferenceEngine { void setArguments(String args); String getArguments(); N3Source launch(); String getWarnings(); // and errors also } |
This is easy to do, but does not take in account the dynamic knowledge base features of Drools. Drools' RuleBase and WorkingMemory are used directly in Project. These existing EulerGUI interfaces should be used more:
ITripleStoreRETE ---|> ITripleStore
The idea is to simply add this method in interface
InferenceEngine
:
/** non dynamic knowledge base can return a NullTripleStore */ ITripleStore getTripleStore();
Note the use of the null object design pattern. A non dynamic knowledge base can also return a real ITripleStore, that can be implemented by parsing and aggregating the N3 sources. This is a service that is not currently provided by EulerGUI.
Here the interface ITripleStoreRETE
is not necessary, as one
can call InferenceEngine.launch()
.
The GUI layer should be able to get a uniform list of services corresponding to the possible inference engines, and bind a Project to an inference engine:
public interface InferenceEngineSupport {
List<InferenceEngineFactory> getInferenceEngines();
}
The interface InferenceEngineFactory is just a place holder for an Inference Engine implementation, and a concrete implementation knows how to create an actual InferenceEngine, and bind it to a Project.
public interface InferenceEngineFactory { InferenceEngine bindInferenceEngine( InferenceEngineFactory e, Project p );
String showShortName();
String showLongName();
}
Now to add SPI support, one can just add an interface
InferenceEngineRegistry
:
public interface InferenceEngineRegistry { void register( InferenceEngineFactory e ); InferenceEngineSupport getInferenceEngineSupport(); }
The interface InferenceEngineRegistry should be implemented as a singleton.
Note that other design goals could be worked on:

TODO I should add that in EulerGUI:
For an inconsistent ontology, Pellet can calculate an "explanation" of the inconsistency, which consists of 1 or more sets of axioms. The combination of all of the axioms in any one of these sets is sufficient to make the ontology inconsistent.
Check out ExplanationExample.java in the "examples" directory of the Pellet distribution for an example of programmatically obtaining explanations. You'll probably want to use the following method of the PelletExplanation class:

I tried a simple rule to flatten a rule base:
{?A => ?C} => {?R a :Rule.?R :hasAntecedent ?A.?R :hasConsequent ?C.} .
When I run with --no-qvars (or without) , the information that EYE has already inferred, namely which variables are existential and which are universal, is lost. Is there a way to recover this information in the output ?
Hi Jean-Marc,
The real good thing about coherent logic is that there is only 1 kind of variable and the quantification is automatic.
So there is ultimately no problem.

Suppose we have a Knowledge Base with basic facts involving one predicate: hasParent, and 3 classes : Man, Woman and Human, and some facts.
Suppose we want to a have the Knowledge Base entail :
Every person has a grandparent.
Then we must first "define" grandparent by a rule using parent in the antecedent.
Then we must have an existential rule for the primitive notion of parent.

ETALIS is an open source system for Complex Event Processing with two accompanied languages called: ETALIS Language for Events (ELE) and Event Processing SPARQL (EP-SPARQL). ETALIS is based on a declarative semantics, grounded in Logic Programming. Due to its root in logic, ETLAIS also supports reasoning about events, context, and real-time complex situations (i.e., Knowledge-based Event Processing). ETALIS stands for Event TrAnsaction Logic Inference System.
ETALIS is implemented in Prolog. The engine runs on many Prolog systems: YAP, SWI, SICStus and XSB. Download ETALIS from here.
Prova Rule Language -- version 3.0.3 is released on October 17, 2010
there's an open thread at http://ubuntuforums.org/showthread.php?t=225019.
at the end of it says:
Fix: Double click on the volume applet, File>Change Devices>AK5370, and raise the volume as high as it goes.
==> It works !!!!!
First thing, we need to enhance the current design and implementation of the Java + N3 engine, based on Drools, with N3 as rule language; this is a unique combination of Semantic Web, rule engine, and Java platform. There is already something working. But the N3 to Drools translator is a simplistic architecture spitting strings along the way; we need something like a compiler technique piloted by rules. And we would like to generate also Jena rules, Mercury code, Scala code, CHR rules. I thought about using N3 rules for transforming input N3, and GF for outputting the final string .
Second thing, we need to design and implement a backward engine for querying SPARQL databases; it will generate a big SPARQL query by recursively accumulating criterium terms, substituting bound variables, renaming variables if necessary.
I think that for point 2, the capabilities of CHR to handle unbound variables can be leveraged.
Another thema is generating user interfaces from high level specifications.
We are on the way to release ICOM 3, the latest reincarnation an old proof of concept which evolved in the last 13 years or so.
ICOM is an advanced conceptual modelling tool, which allows the user to design multiple ER or UML class diagrams with inter- and intra-model constraints, expressed in a rich view but usable language similar to OCL and relational algebra (based on a very expressive description logic).
It is the first time I'm advertising the new version - still in beta; I'd be happy to get comments.

We are considering connecting an OO persistent store to Drools, and I have some questions regarding JPA+Drools.
Is there other documentation besides drools-expert paragraph " 3.3.10. Persistence and Transactions" ? Some design documents ?
How are you storing objects in JPA? User classes as such, or just a limited number or Drools classes, and user classes are stored as serialized blobs ?
How is Drools using JPA Transactions ? After each fireAllRules ?
Is Drools using JPA rollback on its own initiative , or just when the end application calls a roolback ?
Which kind of JPA query is Drools doing ?

There is a nice discussion between participants of CNL 2010. Some (Enrico) want to keep ambiguity in the formal language resulting form parsing the CNL, others (Norbert) want to remove any ambiguity by a strict grammar.

Answer by Aarne:
You need lib/present. This is not produced by Cabal/Setup.hs currently because (as I've been told) Windows doesn't support the preprocessor that making the 'present' library involves. But it can be produced by
cd GF/lib/src
make present
A lighter alternative is to use alltenses instead of present:
i -path=.:alltenses TestAttemptoEng.gf
p -lang=Eng "there are at least ten apples ."
Try this first, so you don't need to compile any libraries. It will make the compilation slower, but should work for all languages except perhaps Finnish ;-)
TestAttempto> p -lang=Eng "there are at least nine apples ." no trees found; unknown words: nine
This one is funny:
TestAttempto> gr | l -treebank TestAttempto: baseText (impVP (theNP beginning_N) (v3VP give_V3 (pnNP england_PN) (allCollNP form_N))) TestAttemptoEng: give all forms to England , the beginning !
These were made with help from TAB :

With subclipse, I could recover my project without re-download from Subversion. I just deleted the project and re-created it.
With subclipse, in the history of a file , I was able to change the Log Message a posteriori.
should implement the file cache for compiled rules bases just for that
==> in fact the message is misleading

By opening with the owl button, examples/car_ace.owl , from a non-empty project for example examples/koala.n3p ), the N3 sources appears twice in the GUI.
However, from a blank project it works fine. Same thing with opening an N3 file .
NOT REPRODUCED !
I sent a mail to the list :
I continued practicing with the tutorial. I came to the dictionary example in 2.7 Abstract types.
Being proficient enough in Prolog, I understand the code in the tutorial.
But I found no example of actually using an abstract type, or other flavours of types.
To be concrete, I wrote this minimal piece of code, but how to create an empty dictionary , with the right type (string) of key and value in variable Dic ?
Dic2 = set( Dic, "jmv", "JM Vanel" ),
search( Dic2, "jmv", V),
io.write_string( "search( dic, jmv, V) : V= ", !IO),
io.write_string( V, !IO) .

jmv_> Hi all
<ctsai-sf> Hello.
<jmv_> When creating a new project, is ti possible to import a whole repository changes database of a previously existing project elsewhere ?
<ctsai-sf> What exactly would you like to import? An SCM repository?
<jmv_> yes
<jmv_> don't know yet if it is CVS, or another
<ctsai-sf> Okay, well, the answer is yes. If you need to import to CVS, you can use the ,,cvsadminrepo tool to do that.
<gribble> You can manage your CVS repository from the shell using the adminrepo tool: http://sourceforge.net/apps/trac/sourceforge/wiki/CVS%20adminrepo
<ctsai-sf> To import to SVN, use ,,svnadminrepo
<gribble> You can manage your SVN repository from the shell using the adminrepo tool: http://sourceforge.net/apps/trac/sourceforge/wiki/SVN%20adminrepo
<ctsai-sf> Or if you're importing to Git, Bazaar or Mercurial, you have direct access to those via the ,,shell if you need that to manage the import.
<gribble> Documentation on the SourceForge shell services is here: http://sourceforge.net/apps/trac/sourceforge/wiki/Shell%20service
<ctsai-sf> And, it's not a necessary step, but, whatever SCM the original source repository uses, you may want to consider migrating to something different before importing.
<jmv_> OK, I already used the SF shell , and I'm mainly working with *sh for 20 years + ; I'm satisfied by your answers :)
<jmv_> But why are writing ,,shell and ,,svnadminrepo with2 commas in front ?
<gribble> Documentation on the SourceForge shell services is here: http://sourceforge.net/apps/trac/sourceforge/wiki/Shell%20service
<gribble> You can manage your SVN repository from the shell using the adminrepo tool: http://sourceforge.net/apps/trac/sourceforge/wiki/SVN%20adminrepo
<ctsai-sf> Because that's the syntax to call the bot (gribble) to post the links.
<ctsai-sf> Factoids rather.
<jmv_> ok :)
<ctsai-sf> Factoids list here: http://gribble.dreamhosters.com/viewfactoids.php?db=%23sourceforge
<ctsai-sf> More info on bot here: http://sourceforge.net/apps/mediawiki/gribble/index.php?title=Main_Page
<jmv_> OK, I saw the factoids page; is there also a web log of the chat ?
<ctsai-sf> No, we are not allowed to have public logs of this channel

Some good questions by Animesh S.:
How does the user ask for some data (e.g. how are menu selections turned into some kind of search)
How does that search get marshalled into something that can be sent to the server
How does the marshalled data actually get transmitted and what does the client do while it’s waiting for a response
How does the server receive the request
How does the server unmarshall the search, and what kind of structure is it unmarshalled into
How is the search sent to the database
How does that data returned by the database get marshalled into something that can be sent back to the client.
How is the marshalled data sent back to the client
How does the client unmarshall the data, and what kind of model does the data get unmarshalled into
What does the client do if the returned data overlaps something it already has in another window, what if the returned data relates to a different entity but has different attributes values
How does the model data get transferred to display fields
When the user makes a change to the displayed fields how is that input validated.
If the change is to data that the user is displaying in another window, how does that other window get updated.
How is the change sent back to the server
How does the server apply the change to the database
How do other clients connected to the same workspace find out about the change
You could also add login/session logic, application of a system filter (e.g. for embargoed data) and application of a user filter on the server. You could then add authorisation features – how does the server check the users authority to do something, what does it do if the user isn’t allowed to do it. Etc. etc.
A more complicated case would use Drools to validate data on the server and retrieve and present validation results.
AceWiki suggestion
export as OWL/RDF or N3
With the EulerGUI tool chain, one can enter ontologies + rules in Controled English with AVE View http://attempto.ifi.uzh.ch/aceview/ , or soon AceWiki http://attempto.ifi.uzh.ch/acewiki/ , and have all this translated in Drools.
There is a set of N3 rules for OWL RL, that can be translated into Drools and executed along with the business rules.
Asked on swig IRC:
What would be the most consensual and widely accepted property for expressing the (dereferentiable) URL origin (file or Web) of an URI ?
<gromgull> jmv: rdfs:seeAlso :)
<gromgull> jmv: I would use the Nepomuk Information Element ontology, but this is hardly consensual
<jmv> danke, gromgull , I'll use rdfs:seeAlso for now , although it's not specific enough ;
<jmv> I had a look at Nepomuk Information Element ontology , but it's a big ontology where I couldn't find my need

Is this the reference version for Attempto Controled English in GF ?

I created the pom.xml file (attached). After that, if you have installed Maven 2, it's possible to run the test suite:
mvn test ... T E S T S ------------------------------------------------------- Running ch.uzh.ifi.attempto.aceeditor.test.ChartParserGenerationTest Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.022 sec Running ch.uzh.ifi.attempto.aceeditor.test.TestGrammar Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.005 sec Running ch.uzh.ifi.attempto.aceeditor.test.ChartParserParsingTest Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.005 sec Results : Tests run: 0, Failures: 0, Errors: 0, Skipped: 0
and then run the sofware:
mvn -Djetty.port=8088 jetty:run
Note that this will do: compile, build, test, build, and launch.
The existing build.xml is not used at all by Maven.

Modified Thu Sep 9 08:12:25 2010 UTC (113 minutes, 34 seconds ago) by jmvanel
project-java-rules.n3 : WIP : add on the LHS:
?ONTO a java:eulergui-project-Project .
But this does not yet compile in Drools on the RHS:
?N3S a java:eulergui-project-N3Source .
?N3S java:URI ?IMPORT. # <<<
?ONTO javam:addN3Source ?N3S .
The N3 rule is now :
{ ?ONTO a java:eulergui-project-Project . ?ONTO owl:imports ?IMPORT. ?IMPORT log:uri ?IMPORT_URI . } => { ?N3S a java:eulergui-project-N3Source . ?N3S java:URI ?IMPORT_URI . ?ONTO javam:addN3Source ?N3S . }. |
TODO: enhance the translator; this is wrong translation :
( N3S_reference ) . setURI( $IMPORT_URI_reference );
Committed revision 1815
refactoring branch:
- Now project-java-rules.n3 compiles in Drools
- updated the class N3JavaMappingBuiltin : Now we store the Java type (String) of the subject of log:uri.
- now when opening a .n3p.n3 file, the N3 sources appears in the GUI ! :)
but TODO: when trying to open an N3 source in the editor:
java.net.MalformedURLException: no protocol: <./catch_allQ.n3> at java.net.URL.<init>(URL.java:567) at java.net.URL.<init>(URL.java:464) at java.net.URL.<init>(URL.java:413) at eulergui.project.N3Source.getLocation(N3Source.java:49) at eulergui.project.N3Source.prepare(N3Source.java:341) at eulergui.project.N3Source.setProject(N3Source.java:306) at eulergui.project.Project.addN3Source(Project.java:296) at eulergui.project.Project.addN3Source(Project.java:291) at n3_project.helpers0.Rule_project_java_rules_n3_3_0.consequence( Rule_project_java_rules_n3_3_0.java:14)
DONE:
- copied the class N3JavaMappingBuiltin from trunk
- in method Project.save() , reestablish the XML format save ( TestProject was broken )
I updated the class N3JavaMappingBuiltin from the trunk,reading projects in N3 get better, but still not good :
INFO: Rule Compilation error : [Rule name='project-java-rules.n3 1'] n3_project/helpers0/Rule_project_java_rules_n3_1_0.java (12:847) : $IMPORT_reference cannot be resolved n3_project/helpers0/Rule_project_java_rules_n3_1_0.java (13:870) : $ONTO_reference cannot be resolved
The problem is that ?IMPORT and ?ONTO are ordinary URI's on the antecedent side, and Java objects on the right side :
rule "project-java-rules.n3 1" when $Triple_1 : Triple( $ONTO : subject, predicate == "<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>", object == "<http://www.w3.org/2002/07/owl#Ontology>" ) $Triple_2 : Triple( subject == $ONTO, predicate == "<http://www.w3.org/2002/07/owl#imports>", $IMPORT : object ) then Triple newTriple; TripleResult newTripleResult; String N3S = Triple.resource("N3S") ; eulergui.project.N3Source N3S_reference = new eulergui.project.N3Source (); insert( new Assignment( N3S.toString(), N3S_reference )); ( N3S_reference ) . setURI( $IMPORT_reference ); ( $ONTO_reference ) . addN3Source( N3S_reference ); end |
One could leverage on the Java object creation that happens in another rule. The criterium in green could be applied on the antecedent side when the predicate is a Java predicate; problems with project-java-rules.n3 : a criterium
Assignment( $ONTO : String, $ONTO_reference : Object,
reference.class == $ONTO_class )
could be applied on the antecedent side when the predicate is a Java prédicate.
rule "project-java-rules.n3 0"
when
$Triple_1 : Triple( $ONTO : subject, predicate == "<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>", object == "<http://www.w3.org/2002/07/owl#Ontology>" )
then
Triple newTriple;
TripleResult newTripleResult;
eulergui.project.Project $ONTO_reference = new eulergui.project.Project ();
insert( new Assignment( $ONTO.toString(), $ONTO_reference ));
end
|
The N3 rule is:
{ ?ONTO a owl:Ontology . ?ONTO owl:imports ?IMPORT. } => { ?N3S a java:eulergui-project-N3Source . ?N3S java:URI ?IMPORT. ?ONTO javam:addN3Source ?N3S . }. |

TODO : upgrade to jEdit 4.3.2, and write a how-to in the manual for upgrading jEdit dependency .
upgrade to Pellet 2.2.1.
Attempto sentence:
Every n : PersonList contains at least one person .
OWL syntax:
PersonList subClassOf contain some person
If there is a n : PersonList X1 then the n : PersonList X1 contains at least 1 person . |
And in N3:
@prefix : <http://www.w3.org/2002/07/owl#> . @prefix acetext: <http://attempto.ifi.uzh.ch/acetext#> . @prefix multi: <http://deductions.sourceforge.net/ontologies/multi.owl#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . acetext:acetext a :AnnotationProperty . <http://deductions.sourceforge.net/ontologies/multi.owl> a :Ontology . multi:PersonList a :Class; rdfs:subClassOf [ a :Restriction; :onProperty multi:contain; :someValuesFrom multi:person ] . multi:contain a :ObjectProperty . multi:person a :Class . [ a :Axiom; acetext:acetext "Every n: PersonList contains at least one person."; <http://purl.org/dc/elements/1.1/date> "2010-08-27 17:23:43"; :object [ a :Restriction; :onProperty multi:contain; :someValuesFrom multi:person ]; :predicate rdfs:subClassOf; :subject multi:PersonList ]. |
Rule:
If there is an OWL restriction on class C and property P, with someValuesFrom, or cardinality>1, or minCardinality>1, or maxCardinality>1, then the field for P should be multi-valued.
Idea:
Is there some method to generalize rules, like when having Swing rules, and generalizing to abstract GUI? It is neither abduction or induction I think.
Slightly extending the OWL format, see "Interoperability with Protégé" and "Proposal for a new ontology and N3 format for RDF + OWL + rules projects" .
I realize that we must somehow merge the classes N3Source and Project. Indeed an N3Source can contain owl:imports triples, which must be interpreted as sub-projects in the EulerGUI sense. In the other direction, a Project will soon be saved as OWL in N3 format.
One way to merge the classes N3Source and Project is to add a new interface,
IN3Source
.
As a side benefit, we can now use unlimited properties about the project itself, like Dublin Core, or simply :
<> rdf:label "name of the project".
to be displayed in the GUI.
Fixed:
examples/car_ace.owl
from an
empty project : the SWRL tranlation into N3 does not appear in GUI :
for an empty project the listeners where not set because prepare() was
not calledexamples/car_ace.owl
to
from a non empty project such as examples/koala.n3p : nothing appears
inside the GUINOT Fixed:
- Many yellow warnings with Eclipse
- new TODO, as in N3Source
I discovered that the start of the branch was worng ( too late ). So I try to re-merge the remaining differences not yet applied.

QUESTIONS
oneOf applied to a Class must be a list of individuals :
http://www.w3.org/TR/2004/REC-owl-ref-20040210/#EnumeratedClass
and oneOf applied to a DataRange must be a list of literals:
http://www.w3.org/TR/2004/REC-owl-ref-20040210/#EnumeratedDatatype
so the translation by Gloze from XSD to OWL must not be :
pmxml_:enumResourceType
a owl:Class ;
owl:equivalentClass
[ a owl:DataRange ;
owl:oneOf (0 1)
] .
but:

On list jena-dev, Thu Jul 8, 2010
I want to write a simple framework to write strings out of RDF graphs, and I want to share ideas about that.
It may , or not, have been done using Jena API.
It is fulfills the same purpose as templating frameworks like FreeMarker, but with more semantics.
As an example, imagine that one wants to write Java classes.
The RDF model has already been prepared, typically by a rule engine, from maybe an RDF Schema.
Then you have something like this:
:C1 a j:Class; j:extends :C2; j:implements :C3; j:hasMethod :m1. :m1 j:hasArgument :a1 . :a1 j:hasType :C4 ; j:hasName "x". :m1 j:hasStatements ([]). |
which should generate this:
public class C1 extends C2 implements C3 { void m1( C4 x ) { } } |
So we have "contained" ("owned") properties like j:hasMethod, j:hasArguments, and j:hasStatements, that need to be expanded in place. And we have "reference" ("pointer") properties that somehow point to another structure, like j:extends, j:implements, j:hasType .
First architecture:
interface RDFExporter { /** returns : public class C1 */ String beginTypedObject( String rdfId, String rdfTypeId); /** returns : extends C2 */ String referenceProperty( String subject, String property, String object); /** returns : { */ String typedObjectContainedPropertySeparator( String rdfId, String rdfTypeId); /** returns : void m1( */ String beginContainedProperty( String subject, String property, String object); /** returns : ) { */ String containedPropertySeparator( String subject, String property, String object); /** returns : } */ String endContainedProperty( String subject, String property, String object); /** returns : } */ String endTypedObject( String rdfId, String rdfTypeId); }
RDFExporter can be implemeted for Java, XML or other formats, or there can be a generic implemetation with plugins for each case. Note that the XXXSeparator mechanism works also for XML.
Second possible architecture: use N3 rules TODO <<<<<<<<<<<<<<???
Third possible architecture: use Prolog DCG .
Here are more use case examples:
In all these cases , white spaces are not significant, and end-of-lines count as white spaces. Also, the "reference" properties are before the "contained" properties.
We suppose that the N3 or RDF has already been transformed by some rule engine, so that (as is the case in the Java source example above):
with possible exceptions for "reference" properties that generate no wrapper "structure";
<urn:blah> ded:associatedFilePath "dir/file.txt"
Any API to walk though an RDF graph is suitable, e.g. Jena's. So one needs to distinguish "contained" property and "reference" property.
In the former case a callback should be called by the framework to close the structure.
But in general, when a Maven plugin has a newer version, can I get a warning ?

We don't try to develop a complete environment from scratch, we develop the core architecture, fill the gaps, and reuse as much as possible.
So this is an open project in every sense of the word. Open to other frameworks, to import-export to other formats.
The main language, N3, is just a readable and widely used variant of the W3C's RDF format. For rule language, there is really no standard, as W3C's RIF (Rule Interchange Format) is very new.
So we will continue to develop or reuse translators with the main logical languages (KIF, RIF, RuleML, Prolog, TPTP, ...).
We developped a translator for the well-established SWRL, and for Drools to reuse the Drools engine.
Unified approach for models + rules + specifications ;
seamless path from specifications to application, but no closed world implementation , but possibility to integrate existing libraries and code.

WIP: cache Drools RuleBase instead of Packages.
~/src/eulersharp/ % Actualisé à la révision 3601.
COMMITED:
pom.xml :
- upgrade to Drools 5.1.0 FINAL
- Added maven-bundle-plugin just for a try (OSGi stuff)
I just uploaded a snapshot of EulerGUI at the usual place:
http://eulergui.sourceforge.net/tmp/
As usual, because of Maven, all tests, unit and functional, (129) have passed.
It embeds Euler.jar from Subversion at today's revision 3601.
It has latest ARQ 2.8.5 ( for SPARQL ), and latest Drools 5.1.0 FINAL (with a bug fix following my report).
The Drools translation is enhanced with better manipulation of RDF lists, less calls to Drools' eval() macro, and above all using Drools' insertLogical() feature in the consequents, activated by default. Drools' insertLogical() does thruth maintenance; it retracts objects automatically when there are no more facts to support the truth of the currently firing rule.
Going hand in hand with the addition of insertLogical() , I stopped adding the negation of the consequent to the antecedent in the Drools translation. This was useless but not harmful before, and with insertLogical() it creates infinite loops.
Other news on the technical side, I 'm looking at Prova for a backward chaining engine , more adapted to reason on databases (SPARQL or SQL ).
I 'm also considering using OSGi and Felix in EulerGUI, for a better modularity and for installing plugins automatically when necessary. Felix is also used in Protégé 4.1 . There are Maven plugins for Felix that may be helpful . An EulerGUI plugin for Protégé 4.1 is planned, but not before ACE View is updated to Protégé 4.1 .
On the business side, I'm still looking for clients being small business developing their own software with domain experts in house. I'm also looking for partnership with classical IT service companies.
I'm also looking for developpers, some Java and some logic-oriented.
I'll attend CNL 2010 in september (http://staff.um.edu.mt/mros1/cnl2010/index.html).
Monday I travel to Mediteranean with 10 or 15 days of rest and cultivating my garden.
Added in N3SourcetoDrools and TripleStoreDrools the recommanded calls :
((StatefulSession)workingMemory).dispose();
TESTS: 2 minutes gained at 9 minutes, but 7 Mb more at 50M.

What is the status of the negation by failure in Mercury?
ws.prova.api2.ProvaCommunicatorImpl
http://felix.apache.org/site/apache-felix-maven-bundle-plugin-bnd.html
First I added a completely vanilla configuration in my pom.xml :
<plugin> <groupId>org.apache.felix</groupId> <artifactId>maven-bundle-plugin</artifactId> <extensions>true</extensions> <configuration> <instructions> </instructions> </configuration> </plugin>
Then , just for a try:
mvn org.apache.felix:maven-bundle-plugin:manifest ... [INFO] [bundle:manifest {execution: default-cli}] [WARNING] Warning in manifest for eulergui:eulergui:jar:1.7-SNAPSHOT : Superfluous export-package instructions: [com, net.sf.parser4j, net.rhizomik, eulergui.parser.n3, eulergui.infrastructure, eulergui.parser.n3.impl, eulergui.gui, eulergui.parser, org.gjt.sp, org.gjt, org, net, net.sf.parser4j.parsetreeinspector, eulergui.parser.umlt, com.hp, net.sf, jdepend, n3_project.exceptions, net.sf.parser4j.parser, eulergui.parser.n3.impl.parser4j, eulergui.n3model.service] [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESSFUL
This created :
target/classes/META-INF/MANIFEST.MF
I like the warning, it looks smart, these packages indeed not suitable for export.
Now to go further, I should learn more about OSGi and Felix.
The Apache Felix Maven SCR Plugin is a great tool to ease the development of OSGi components and services. Components and services are defined through annotations and the plugin creates the necessary descriptors for the OSGi Declarative Services, Config Admin and Metatype services.
Differences with Prolog of the Prolog subset of Prova.
Differences are far greater than similarities. Prova is a system for reactive agents, workflows, and event processing, as well as a number of specialized reasoning modes, like deontic logic and ontology derived typing. Prova allows you to work directly with Java datatypes and classes so you can write algorithms that are very awkward to write in Prolog. You have annotations, reaction groups, reactivity bassed on direct continuations. Prova keeps lists in arrays. The differences are so many that pretty much you can say, there is very little in common with Prolog proper in terms of WHAT you can write with Prova.
Differences with Mercury.
???
Would it make sense to implement the JSR 94 API with ProvaCommunicator?
I'm not sure about the value of this. We discussed this with Mark Proctor of JBoss and he had really cold feet about the need for it. Prova is a reactive agent language. We use it in an OSGi container or behind ESB and interact with it by sending and receiving messages. Every Prova goal is a message and goal execution is a reaction so Prova is not a rule language, it is a reactive agent language.
Are gards in Prova the same as guards in CHR ?
@author(dev22) r2(X):-q(X). @author(dev32) r2(X):-s(X). trusted(dev1). trusted(dev22). % Author dev22 is trusted but dev32 is not, so one solution is found: X1=2 p1(X):- @author(A) r2(X) [trusted(A)]. :-solve(p1(X1)).
It is clear that the guard is attached to a body literal rather than
the body. You can use annotation variables together with it. You can
use CUT inside for splicing in a dynamic CUT.
Typo in manual 2.0 : commas and point instead of semicolon, % instead of // , no import for Map, missing public for class, incorrect signature for main
class test_collections { int main() { Map map = new java.util.HashMap(), % HashMap Constructor map.put(0,"false"), % Instance method calls map.put(1,"true"), System.out.println("Map="+map). % Built-in printing } }
Surefire is the Maven plugin for tests.
http://maven.apache.org/guides/development/guide-testing-development-plugins.html
Upgrade this in the pom.xml:
<version>2.6-SNAPSHOT</version>
Add this in ~/.m2/settings.xml :

<jmv> In maven-surefire-plugin, when I add <argLine> tag inside <configuration> , this disactivates the -D command line argument ; bug or feature ?
<bentmann> this is not related to a single plugin but applies to maven in general, i.e. explicit POM configuration is dominant over CLI args
<bentmann> whether this is really nice/intended, is indeed a good question
<bentmann> but one can always just use the project's <properties> to reach the same effect for those params
<jmv> bentmann, well, is this case I'm adding -D arguments that are not Maven specific, I think they should pass.
<bentmann> I can't follow
<jmv> I mean, when it's a Maven parameter like -DforkMode=pertest , it is good that the POM forkMode applies, but in my case it's a system variable that is not known to Maven .
<bentmann> do you mean http://jira.codehaus.org/browse/SUREFIRE-121 ?
<jmv> bentmann, yes, so this has been fixed 3 days ago :)
<jmv> is there any inconvenient to migrate to Maven 2.1.0 ?
<bentmann> Maven 2.1.0 and 2.2.0 aren't really recommended due to issues with checksum generation upon deployment
<bentmann> so if you consider upgrading, you should aim for Maven 2.2.1
<bentmann> I can't remember any major breaking change between 2.0.x and 2.2.1, so upgrading should generally be rather smooth, you could check the release notes for details
<bentmann> in any case, you want to make sure you have all your plugin versions locked down, otherwise newer default versions used by Maven 2.2.1 might cause surprises
<jmv> bentmann, well in fact in already use 2.2.1 (rdebian-1) ; so the the -DmyArg=bla should be active in mvn test ?!
<jmv> I already use 2.2.1
<bentmann> if you use the surefire plugin from SVN trunk
<jmv> I thought that Maven was updating itself, can I do this updating of surefire that without recompiling myself surefire ?
<bentmann> maven doesn't update itself
<bentmann> and no, you would have to build surefire yourself
<jmv> bentmann, Ok, so Maven takes exactly the versions of plugins that are in the POM; it doesn't update itself, it just dowloads what is not already in the local repo , correct ?
<bentmann> yes
<jmv> But in some cases, can't Maven download a bug fix at the same version level ?
<bentmann> nope, in fact automatic plugin updates (in case the POM doesn't specify a version) are considered a danger to the build which is why this behavior is scheduled for removal
<bentmann> besides, the new surefire plugin isn't released yet, so there's nothing to download
<jmv> thanks bentmann , any clue about a date for surefire 2.6 ?
<bentmann> no

I tried semanticreports.com and created my own :
http://semanticreports.com/reports/2e534985-efc9-4912-b338-b68e79f1a23d
I see the potential .
I'd like to add that to my EulerGUI tool, if that 's open source .
Is there a code sample showing how one can reuse the Maven core to enable an application to load dependencies as needed?
I think to embed a Maven kernel to load dependencies as and when required, as Maven does itself. I guess I must, at each start of each feature, add a call to some method to load needed dependencies. Apart from that, there are other things to develop?

My introduction on the Drools IRC:
I'm Jean-Marc Vanel from Versailles France, and I'm using the Drools API in my Semantic Web application, EulerGUI, where I generate Drools code from other rule langages.
inference engines ( maybe Jena ? )
Project
Pave the way for using Drools' insertLogical() feature in the GUI by default
- switch in class RunDroolsAction
- not activated yet because of tests and examples of form generation not updated
added an update of swing-rules3.n3p for use with Drools' insertLogical() feature (activable in EulerGUI in class RunDroolsAction).
https://deductions.svn.sourceforge.net/svnroot/deductions/n3_logical
conan, Good news!
After good advice from Edson, my form generator works fine with insertLogical() in most places.
It actually simplifies the Drools code generation.
But there is still a problem with the GUI callback.
It seems that 3 things play baldly together:
With these ingredients I get an infinite loop. The object that has been logically inserted is updated to the same (equal) value, but it triggers the rule anyway.
...
sure, but my point is that The object that has been logically inserted is updated to the same (equal) value; that should not triggers the rule, because of AssertBehaviour.EQUALITY option.
jmv> conan, adding no-loop to the relevant places only (that is, the rules with update or retract, works ! :)
Note that I wanted to use -DforkMode=pertest because I had OutOfMemory : PermGen space on Linux 64 bit , but not on Windows.

In Drools, can I refer to Conditional Element to add criteria to it , like this :
$v : Class1 ( prop1=="x" )
$v == Class1 ( prop2=="xx" )
of course this does not compile ...
It would be convenient because I generate Drools code ...
I FOUND !!!
$v : Class1 ( prop1=="x" )
Class1 ( this==$v, prop2=="xx" )
So the translation for
?X :p :v. :s :q ?Y. ?X log:notEqualTo ?Y.
would be:
$T1 : Triple( $X: subject, ... ) $T2 : Triple( $Y: object, ... ) Triple( this==$T1, subject != $Y )
e:findall
when empty resultnow use
not( exists( conjunction_of_criteria )
instead of
TripleList( $XXX_s_SIZE_ : size) from collect( ) eval( $XXX_s.isEmpty() )
TESTS PASS
The advantage is that now a findall with several criteria is possible.
How to say that in Drools ?
The set of orders for the client X for the item Y has cardinality N.
Said another way:
How can I in the LHS get the set of all values of variable $V satisfying the criterium :
Class1( $V : prop1 , ... ) Class2( prop2 == $V , ... ) ...
<etirelli> jmv: something like:
$vs : Set() from accumulate( Class1($v:prop1) and Class2( prop2==$v ), collectSet( $v ) )
This will be useful to simplify the translation of
e:findall
.
DONE
More on collectSet and collectList :

https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-introduction/html_single/index.html#d4e160
set Drools insertLogical by default, without spoiling the existing demos and tests : set useInsertLogical==false just for the 2 tests that need it
implement findall with empty result with not( exists ( ... ))
implement findall with several criteria with from accumulate( ...
collectSet( $v ) )
( see above )
I did not work the first time !
e:findall
seem to be a problem.
This way I could simplify the translation into Drools of my N3 rules ... and benefit of the automatic retractions by insertLogical() . But maybe discover new problems ...
Merci à Edson Tirelli !
This works when one removes the not() clause.
rule "domotic-rules.n3 0" when $Triple_2 : Triple( $t0: subject, predicate == "<http://www.simple-ontology.owl#hasControl>", $t1 : object ) $Triple_3 : Triple( subject == $t1, predicate == "<http://www.simple-ontology.owl#hasState>", $t2 : object ) not( $Triple_4 : Triple( subject == $t0, predicate == "<http://www.simple-ontology.owl#hasState>", object == $t2 ) ) then Triple newTriple = new Triple( ); newTriple.setSubject( $t0 ); newTriple.setPredicate( "<http://www.simple-ontology.owl#hasState>" ); newTriple.setObject( $t2.toString() ); insertLogical( newTriple ); // insert ( newTriple ); System.out.println( "insertLogical( "+ newTriple); end
Is there a mvn command to download a pom from the Web , create a local project directory, download the sources, and build , all in one step ?
scm:bootstrap is close to what I want : http://maven.apache.org/scm/maven-scm-plugin/examples/bootstrapping-with-pom.html
but one still needs to have a small bootstrap pom.xml locally , if I understand ...
I'd like something like :
mvn scm:bootstrap_from_URL http://eulergui.svn.sourceforge.net/viewvc/eulergui/trunk/eulergui/pom.xml
I have a rule base with a single rule saying "if the switch has a state, then the light has the same state".
<jmv> I'm trying to use insertLogical on the RHS to avoid having to explicitely remove the lamp's old state, but Drools enters in an infinite loop ...
<jmv> The only example I have with insertLogical is with exists on the LHS ...
<jmv> bug, feature, or workaround ?
<etirelli> jmv: ok... look, the rule is evaluated, it is true and then it executes
<etirelli> the consequence of the rule logically inserts a fact
<etirelli> jmv: lets call it lf
<etirelli> lf matches the "not" pattern
<etirelli> making the LHS false
<etirelli> so the engine automatically retracts lf
<etirelli> the retraction makes the rule true again, since that fact is not there anymore
<etirelli> so the rule fires again...
<jmv> ok, i see,
<jmv> so removing the not() would work ...
<etirelli> well, removing the not would prevent the rule becoming false after it is executed
<jmv> somehow insertLogical does the job of the not() here in this case
<jmv> let me try
<jmv> ok, works fine
<jmv> fire just once
<etirelli> cool :)

newTriple.setObject( $t2.toString() );
insertLogical( newTriple );
// insert ( newTriple );
System.out.println( "insertLogical( "+ newTriple);
end
Is insertLogical supposed to work with AssertBehaviour.EQUALITY ?
About the exists pattern; in the doc. there is "Since only the existence matters, no bindings will be established." is this a limitation by design to ensure cleaner rules, or a limitation of the implemetation ?
Use case : one might want to say xists Bus(color == "red", name: brand ) and print name .

I asked myself the question of finding a simple cache implementation, to keep both compiled by Drools rules, and the documents downloaded from the Web.
http://sourceforge.net/search/?type_of_search=soft&words=java+cache
http://www.opensymphony.com/oscache/wiki/API%20Usage.html
http://www.opensymphony.com/oscache/wiki/Configuration.html
I'd like to have a Java persistent cache with these features :
dependency management like the Unix make utility; for example a rule package compiled by Drools is dependent on a URL of the Drools source
A rule base could do the job ! The main rule could be: If there is a dependency from A to B, and A's timestamp is younger than B's , then B is remade. Let's leave that aside for now (the idea behind Déductions is that Object Oriented code is good for infrastructure, and rules are rather for domain objects).
The implementation will need to get the timestamp from an URI, and the actual timestamp of the cached stuff.
An API draft :
interface URICache { /** @return retrieves Object if up-to-date, otherwise returns null. */ Object getCachedURIAsObject( String uri ); /** automatically retrieves up-to-date versions of File or Object */ void cacheObject(String uri, Object object); File getCachedURIAsFile( String uri ); }
An SPI (Service Provider Interface) draft :
/** encapsulates an algorithm to "compile" an URI to a Java Object - UNUSED */ interface URICompiler { /** @return non null <=> this object knows how to cache this object */ Object compileURIAsObject( String uri ); } /** This SPI (Service Provider Interface) is the raw cache that unconditionally stores given objects or dereferenced URI's */ interface URICacheStore { void cacheObject( String uri, Object object ); File cacheURIAsFile( String uri ); long getObjectTimeStamp( String uri ); Object getObject( String uri ); File getFile( String uri ); }
boolean needsRefresh( String uri );
To implement the URICache, I need to persist a Map from URI's to Objects, and it should be safe for concurrent access.
I could use OSCache 2.4 from Maven, it's only 131 kb:
http://mvnrepository.com/artifact/opensymphony/oscache/2.4
They write, which is good :
Persistent Caching - The cache can optionally be disk-based, thereby allowing expensive-to-create data to remain cached even across application restarts.
With OSCache, the interface EntryRefreshPolicy can encapsulate the logic of data expiration, with this single method :
boolean needsRefresh(CacheEntry entry)
However, I don't like that the logic of data expiration is separed from the logic of data refreshing , which happens in this code sample:
try { // Get from the cache myValue = (String) admin.getFromCache(myKey, myRefreshPeriod); } catch (NeedsRefreshException nre) { try { // Get the value (probably from the database) myValue = "This is the content retrieved."; // Store in the cache admin.putInCache(myKey, myValue); } catch (Exception ex) { // We have the current content if we want fail-over. myValue = (String) nre.getCacheContent(); // It is essential that cancelUpdate is called if the // cached content is not rebuilt admin.cancelUpdate(myKey); } }
So I had a look at the implementions of persistant maps in Java .

It seems related to having a not too small Working Memory (622 objects), and then compiling and adding several not too small rules packages. It runs fine on 5.1.0.M1 and before, but crashes 5.1.0.M2 and on today's 5.1.0.SNAPSHOT.

You can run the main class this way:

One can buid simple auxiliary classes or properties just as a support for making forms. Then there will be rules like this to update "real" triples from the auxiliary classes or properties.
{ ?M :hasXAcceleration ?G. ?M :hasElapsedTime ?T. ( 0.5 ?G ?T ?T ) math:product ?X. } => { # :d kb:retract ( ?M :hasX ?OLD_VALUE ). ?M :hasX ?X. _:d eg:trace ( "Acceleration computed" ?G ?T ?X ). }.
Idea: use this to denote a Parameter of a query:
gui:hasForm a :Parameter.Idea: make a rule to find rules having some property P in their consequent.
{ ?A => ?C. ?C log:includes { ?IA ?P ?IC } } => { { ?A => ?C } :result ( :includes_property_in_consequent ) . }.
Working with eulergui/examples/acceleration_form.n3p
We could refresh all the GUI fields for the subject being edited, but we really need an observer pattern.

Is it as simple as with Scala to mix Java and Mercury ?
A Java ‘pragma foreign_type’ declaration has the form:
:- pragma foreign_type("Java", MercuryTypeName, "JavaType").
The JavaType can be any accessible non-primitive Java type.
The effect of this declaration is that Mercury values of type MercuryTypeName will be
passed to and from Java foreign procs as having type JavaType.
Is there a command line interactive interpreter tool in Mercury ?
For "green" cuts , it is sufficient that the compiler accepts the Mercury at the syntactic level.
For "red" cuts the developper should do something by hand, as explained in mercury_trans_guide. I wonder if it is feasible to automatically detect "red" cuts, at least in some cases. Or if there are standards for declaring a cut "red".
Posted here: http://tomschrijvers.blogspot.com/2008/02/types-for-prolog.html
How easy would it be to add probabilistic features to ATTEMPTO, e.g. fuzzy logic ?
I wonder if all the cuts in ACE are green cuts.

SOAR is a RETE engine , and more. At the start of the tutorail , it looks like an english interface to Java:
hello-world: If I exist, then write “Hello World” and halt.
This looks superficially like ACE (ATTEMPTO) :
water-jug*elaborate*empty If the state is named water-jug and a jug can hold volume v and currently has contents c, then add that it has v – c available (empty) space.

I wonder if a translation from ATTEMPTO DRS to KIF would be easy. It would allow one to enter new knowledge into the SUMO family of ontologies.
The reverse translation from KIF to ATTEMPTO DRS would allow one to verbalize KIF and SUMO stuff. But there is already some tools for this.

After switching to Drools 5.1.0.M2, eulergui-1.7-SNAPSHOT-jar-with-dependencies.jar is now

For example: generate XML, or classes in Java or Python, or other Knowledge Representation languages like KIF (Knowledge Interchange Format).

My modifications of the ACE --> OWL translator are commited in the Déductions depot on Sourceforge in directory ape/ . To download them:
svn co
https://deductions.svn.sourceforge.net/svnroot/deductions/ape
I used this snippet for testing :
If a n:rectangle R has a n:length L1 , and R has a n:length L2 , and S = ( L1 * L2 ) then R v:has-surface S .
I also tested the same, but with the formula moved in the consequent (not suited to EulerGUI )
If a n:rectangle R has a n:length L1 and R has a n:length L2 then R v:has-surface S, and S = ( L1 * L2 ) .
I generated the SWRL with Prolog in command line.
The generated SWRL looks good in Protégé 4.1 and 4.0 , visualized as :
length(?x2), length(?x4), rectangle(?x1), Thing(?x6), have(?x1, ?x2),
have(?x1, ?x4), multiply(?x6, ?x2, ?x4) -> has-surface(?x1, ?x6)
and in EulerGUI , translated in N3 as:
{?t0 a ns1:rectangle. ?t1 a ns1:length. ?t2 a ns1:length. ?t0 ns1:have
?t1. ?t0 ns1:have ?t2. (ns1:x2 ns1:x4) math:product ?t3} => {?t0
ns1:has-surface ?t3}.
:(((((((( Alas in Protégé, after selecting "ACE local" in the ACE View preferences, and when adding this snippet:
If a n:rectangle R has a n:length L1 and R has a n:length L2 then R v:has-surface S, and S = ( L1 * L2 ) .
I get this exception . This exception is not present when reparsing tens of snippets that were already in the opened OWL file. This exception is also not present when using the ACE --> OWL translator in Zürich (there is another exception saying that the OWL is empty).

Happily it works when selecting "ACE web service" and http://localhost:8000/ in the ACE View preferences, after starting the web service :
./ape.exe -httpserver
The things that work with ace_to_owl.pl work also with the standard ape.exe
, but one needs to run ./make_exe.sh
to refresh
ape.exe
.
./ape.exe -guess -text 'If a n:rectangle R has a n:length L1 , and
R has a n:length L2 , and S = ( L1 * L2 ) then R v:has-surface S .'
-cowlrdf
returns the right result
./ape.exe -guess -text 'If a n:rectangle R has a n:length L1 , and
R has a n:length L2 , and S = ( L1 * L2 ) then R v:has-surface S .'
-cowlfsspp
returns the right result
./ape.exe -guess -text 'If a n:rectangle R has a n:length L1, and R
has a n:length L2 then R v:has-surface ( L1 * L2 ) .' -cowlrdf
returns empty result; my modifications are not trigerred in this case;
but -cowlfsspp returns the right result, and OWL XML returns
<Consequent> <description> <DataProperty URI="http://test#has-surface"/> <I-variable>x1</I-variable> <expr> <*/> <I-variable>x2</I-variable> <I-variable>x4</I-variable> </expr> </description> </Consequent>
The OWL RDF is empty, and the OWL XML is not correct :
<builtIn> <multiply/> <I-variable>x4</I-variable> <expr> <*/> <expr> <*/> <expr> <//> <int cardinality="1"/> <int cardinality="2"/> </expr> <$VAR cardinality="2"/> </expr> <$VAR cardinality="3"/> </expr> <I-variable>x3</I-variable> </builtIn> </Consequent>
First this is for the ACE==>OWL+SWRL translator.
See aceview : Which APE interface to use?
I made this script to start ACE View with the right initialization for JPL.
( eval `swipl -dump-runtime-variables` export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/$PLARCH:$LD_LIBRARY_PATH export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/$PLARCH/server:$LD_LIBRARY_PATH export LD_PRELOAD=$PLBASE/lib/$PLARCH/libjpl.so echo export LD_PRELOAD=$PLBASE/lib/$PLARCH/libjpl.so \; LD_LIBRARY_PATH=$LD_LIBRARY_PATH cd ~/apps/Protege_4 # ./run.sh -Djava.library.path=$PLBASE/lib/$PLARCH $* & java ${CMD_OPTIONS} -Xmx200M -Dosgi.clean=true -DentityExpansionLimit=100000000 -Dfile.encoding=utf-8 \ -Djava.library.path=$PLBASE/lib/$PLARCH -jar org.eclipse.osgi.jar $* & )
Second this is for the OWL==>ACE translator (SWRL is not implemented in this direction).
See aceview : Installing the OWL verbalizer locally
In make_exe.sh , had to change this:
# jmv swipl=/opt/local/bin/swipl
swipl=swipl # jmv
Then I can start the server :
./owl_to_ace.exe -httpserver -port 5123
and change the setting of the ACE View plugin.

Pay attention to the syntax, especially if the words are unkown. ACE can be completely wrong, even if the paraphrase looks good:
./ape.exe -guess -text "The brain arteriovenous malformations have dilated arteries." \ -solo syntaxpp specification ____________________|____________________ s | __________________|__________________ | np vp | __|__ | | det nbar vbar | | | ____________|_____________ | | n vcompl vmod | | | ________________|_________________ | | | | v np prep np adv | | | | | | | | | | | | pname | pname | | | | | | | | | | the brain arteriovenous malformations have dilated arteries .
The first remedy is to add prefixes for word types:
./ape.exe -guess -text "The n:brain a:arteriovenous n:malformations have a:dilated n:arteries." \
-solo syntaxpp
Then you see that the syntax was in fact wrong:
the n:brain a:arteriovenous <> n:malformations have a:dilated n:arteries ."
This is the first sentence that was not ACE. The sign <> indicates the position where parsing failed.
From this, one should understand (sic!) that the combination noun + adjective is here forbiden. I also add the missing "some"; see "2.1.2 Plural Countable Noun Phrases" in ACE construction rules . ACE is quite fussy about articles and determinants .
./ape.exe -guess -text "The a:arteriovenous n:malformations of the n:brain have some a:dilated n:arteries." \
-solo syntaxpp
Maybe the verb "have" could be replaced with a less general verb, like "consist-in".
The original sentence was:
Brain arteriovenous malformations have dilated arteries and veins with dysplastic vessels and no capillary bed and no neural parenchyma.
Now it's easy to complete the ACE rewriting of the original sentence:
All a:arteriovenous n:malformations of a n:brain have some a:dilated n:arteries, and veins with some a:dysplastic vessels, and have no a:capillary bed, and have no neural n:parenchyma. |
The embolization can be used as an initial procedure or the only technique.
which we rewrite thus:
It is possible that an n:embolization is used as an a:initial n:procedure, or is used as an a:only n:technique. |
In this example, the following is noteworthy:
The cerebral aneurysm can be saccular, fusiform or dissecting.
which we rewrite thus:
A a:cerebral n:aneurysm is a:saccular, or is a:fusiform, or is a:dissecting. |
In this example, the following is noteworthy:
ACE crashes, due a bad update in the trunk, but happily ACE editor works.

Since there is several days of work to make it work, I postponed N3 Java Mapping Builtin.
[FEATURE] Creation of an input Form from a click in Class tree, using rules from Déductions project
class CreateClassFormMouseListener: uses JavaScript Instanciation, not the new
N3JavaMappingBuiltin
Add some Java declaration in N3 for the new N3 Java mapping (WIP)
Mark :inputSpecification as :InfrastructureProperty , in addition to being a owl:ObjectProperty (WIP)
add axiom for owl:intersectionOf :
{?C owl:intersectionOf ?L. ?D list:in ?L} => {?C rdfs:subClassOf ?D}.

Variable not yet intanciated in Java involved in method call
DIFFICULT
Triples like this involves a variable ?JPANEL_FIELD that is not yet intanciated at the Java level :
javapr:GUIKBAdapter javam:add (?JPANEL_FIELD ?JLABEL_DT 0).
With the post-translation into JavaScript, we had the flexibility to do that, because all the object creations are done before all the method calls.
This is difficult with the new N3 Java Mapping, but it seems that moving method call in other rules were a Java type can be inferred or assigned brings a solution. This would also bring a a better separation of rule layers (see Supporting ontologies).
But see also "Predefined Java objects" below for another solution.
Variable declared in the consequent side as an abstract Java type
SIMPLE, SEVERAL SOLUTIONS
Related to previous problem, here the variable ?JPANEL_FIELD is declared in the consequent side as an abstract Java type, just to enable subsequent call (otherwise Drools will not compile). No object creation must occur for abstract Java type, just declaration.
?JTEXT_FIELD a java:java_awt_Component .
javapr:GUIKBAdapter javam:add (?JPANEL_FIELD ?JLABEL_DT 0).
This must be combined with
Using introspection for Java calls
Another solution to avoid altogether such declaration in N3 is to use introspection (a.k.a. reflection) in the generated code, probably using Spring core framework reflection and introspection library (need a code sample).
Pure N3 variable in Java involved in method call
DIFFICULT
In this fragment, the variable ?INDIVIDUAL will never be instanciated at the Java level. So it must be added as String in the Java method call.
?Property rdfs:range ?CLASS . ?INDIVIDUAL a ?CLASS . ... } => { ?JCOMBOBOX javam:addItem ?INDIVIDUAL . } .
I see no way of faclitating things in the framework. The designer will have to declare the variable in N3 , e.g. here:
?INDIVIDUAL javac:java_lang_String ( ?INDIVIDUAL ) .
where the N3 prefix javac: represents a Java constructor. This will be a new possibility in the Java - N3 mapping . It would have to be implemented in the class Instanciator also, for compatibility.
Predefined Java objects
SEVERAL SOLUTIONS
In the post-translation into JavaScript, the predefined Java objects (e.g. GUIKBAdapter) were just added as JavaScript variables to the JavaScript engine. They didn't need to be detected and processed neither in thr translator nor in the instanciator. Now it is different.
javapr:GUIKBAdapter javam:add (?JPANEL_FIELD ?JLABEL_DT 0).
I see 2 solutions:
Assignment( name = "<http://../GUIKBAdapter>" , reference.class = ?GUIKBAdapter_class reference = ?GUIKBAdapter_reference )
In both cases the Drools Working Memory must be populated beforehand, in different ways.
Solution 1. also solves elegantly issue "Variable not yet intanciated in Java involved in method call". But the Java must be declared in N3, or otherwise use introspection.
N3JavaMappingBuiltin : WIP : for the Swing rules,
solve problems with empty lists, and boolean in arguments of Java methods , e.g. :
( JFRAME_reference ) . setVisible( true );
( JFRAME_reference ) . setSize( 600, 300 );
( JFRAME_reference ) . pack( );
( JFRAME_reference ) . toFront( );

java_event-rules.n3 : add declarations in N3 of Java types
I added these declarations in java_event-rules.n3 ; example person_import3.n3p still works .
{
?JTEXT_FIELD a java:javax_swing_JTextField .
?JEVENT a java:java_awt_Event ;
javap:ID 1005 ; # 1005 means FOCUS_LOST in Swing class FocusEvent
javap:source ?JTEXT_FIELD ;
javap:temporary false .
?JTEXT_FIELD javapr:generic_field ?FIELD .
?JTEXT_FIELD javap:text ?TEXT .

?JEVENT a gui:FocusLostEvent ;
gui:eventSource ?FIELD
; gui:newValue ?TEXT .
_:d eg:trace ( "FocusLostEvent" ?JTEXT_FIELD ?FIELD "gui:newValue" ?TEXT ) .
} .
But for other rules files like generic_gui_projection-rules.n3 , this reveals an architectural problem . This rule file is not supposed to depend on Java vocabulary. But it does, e.g. :
# instantiate a (naked) window
{ ?APPINST app:hasWindow ?PANE
} => {
?JFRAME a java:javax_swing_JFrame .
?PANE javapr:projection ?JFRAME .
?JFRAME a gengui:Frame .

# ?FlowLayout a java:java_awt_FlowLayout .
#?FlowLayout a gengui:FlowLayout .
#?JFRAME javam:setLayout ( ?FlowLayout ).
?JFRAME javam:pack () .
?JFRAME javam:toFront () .
_:d eg:trace ( ">>> instantiated a window" ?JFRAME ).
} .

Swappiness lets an admin decide how quickly they want the VM to reclaim mapped pages,
rather than just try to flush out dirty page cache data. The algorithm for deciding whether to
reclaim mapped pages is based on a combination of the percentage of the inactive list scanned
in an effort to reclaim pages, the amount of total system memory mapped, and the swappiness
value.
By tuning swappiness up, the kernel will dedicate more resources to try to free existing
memory pages in RAM, generating less I/O, but also increasing system CPU time. If your system
is running at acceptable levels and you have 20% to 30% idle time, you may tune this parameter
higher to dedicate more CPU time to freeing memory.
By tuning swappiness down, the kernel will spend less system CPU time freeing memory and
generate more I/O. If your system is CPU intensive with relatively idle I/O, then tuning this
parameter down will decrease CPU cycles and leverage the idle I/O channels. I/O is not CPU
intensive or expensive.

In deductions/n3_new/test/aceview_swrl_tests.owl , these sentences do not pass right now:
Everybody likes everybody.
does not pass right now, because I excluded arbitrarily the criterium :
?X a owl:Thing.
REMEDY: keep this criterium when there is no other criterium for ?X
129: Every man that owns a car and that is not a manager cleans the car.
because we do not translate this :
<swrl:ClassAtom> <swrl:argument1 rdf:resource="#x1"/> <swrl:classPredicate> <owl:Class> <owl:complementOf> <owl:Class rdf:about="#manager"/> </owl:complementOf> </owl:Class> </swrl:classPredicate> </swrl:ClassAtom>
Which reads as SWRL:
car(?x2), man(?x1), not (manager)(?x1), own(?x1, ?x2) -> clean(?x1, ?x2)
REMEDY: translate as:
?x1 a ?CLASS . ?CLASS rdfs:subClassOf ?SUPERCLASS. ?SUPERCLASS log:notEqualTo :manager .
COMMENTS:
not (manager)(?x1)
in SWRL means " ?x1 is not provably
member of class manager" ; while the proposed N3 translation applies
negation as failure137: For every day a man does not see a woman.
because we do not translate this :
<swrl:classPredicate> <owl:Class> <owl:complementOf> <owl:Restriction> <owl:onProperty rdf:resource="#see"/> <owl:someValuesFrom> <owl:Class rdf:about="#woman"/> </owl:someValuesFrom> </owl:Restriction> </owl:complementOf> </owl:Class> </swrl:classPredicate>
REMEDY: use findall :
findall( ?MAN {?MAN :see ?W. ?W a :woman.} () ).
COMMENTS:
I added a simpler test without complementOf :
For every day a man sees a woman.
<swrl:ClassAtom> <swrl:argument1 rdf:resource="#x2"/> <swrl:classPredicate rdf:resource="#man"/> </swrl:ClassAtom> ... <swrl:classPredicate> <owl:Restriction> <owl:onProperty rdf:resource="#see"/> <owl:someValuesFrom> <owl:Class rdf:about="#woman"/> </owl:someValuesFrom> </owl:Restriction> </swrl:classPredicate>

?MAN :see ?W. ?W a :woman.
Or , rather (no need to create a variable) :
?MAN :see [ a :woman ] .

REMEDY: owl:unionOf should be translated using e:disjunction , and owl Restriction onProperty by a simple triple:
( {:John :see ?D. ?D a :dog.} { :John:see ?C. } { ?C a :cat.} ) ! e:disjunction .
185: If a man owns a car then the man likes the car and likes exactly 3 cats.

REMEDY: in antecedent , use findall and math:memberCount , and make the Unique Name Assumption
findall( ?MAN {?MAN :like ?C. ?C a :cat.} ?CATS ). ?CATS math:memberCount 3 .
On consequent side, I think it's not possible with a RETE engine ??? , but maybe with Euler.

owl ontology vocabulary computation simulation formulas
Hi
I set myself the use case of making a tool that, out of an algebraic formula with identified variables, in OWL, will generate a small GUI with a form to enter the values and a display of calculation result .
For a concrete example, consider the accelerated movement formula:
D = 1/2 G T*T
There would be an input field for the acceleration G (nice to have : default value 9.81), one for the elapsed time T, and a display of the distance D.
With the EulerGUI - Déductions framework, we have the form generator. We will implement the display of selected inferred statements.
I come to my question.
With this use my mind, I would like to re-use an existing ontology.
Of course I looked in the usual places. This morning , the swoogle site is temporarily unavailable. Watson gave nothing suitable. In the tones repo I found sme ontologies from dumortier.com (see below).
The main notions I need are :
expression, variable, value, parameter, result, quantity
A difficulty is that a variable can be considered as an independent variable or as a parameter, depending on context and usage of a formula. But for a first approach I can do without these notions.
In the domain of unit of measurement , unity , dimension , I found this in Tones:
http://ontology.dumontierlab.com/property-complex
but dimensional analysis is rather sketchy there.
Later I will need ontology about :
equation , solver
Tried the owl swrl test of sent by Kaarel.

Verbalizing OWL in Attempto Controlled English
Kaarel Kaljurand and Norbert E. Fuchs
Upload snaphot : SCM-Revision: 1653
In fact, I don't even know how an algebric expression would be in OWL+SWRL.
I guess it uses the SWRL builtins for mathematical operations.
But what if it is pure OWL ?
Pending the correction Kaarel mentionned last time, I need some workaround to make my small demonstrator that will interpret the math formulas and show some input forms.
Given some hints, I can try to arrange the Prolog code ...
Here is the sentence that was not working with ACE View (cf mail from Kaarel, april 19) :
This seems to be a bug:
./ape.exe -text "For each mobile M for each n:acceleration G for each
elapsed-time T there is a distance D such that M travels-during the
elapsed-time T, and D is (1/2)*G*T*T." -guess -solo owlrdf
Results in:
ERROR: Unexpected error.
The bug is that transformation from SWRL functional syntax into RDF/XML fails
I simplified the sentence (removing the red part ) that was not working with ACE View :
For each mobile M for each n : acceleration G for each elapsed-time T there is a distance D ,
and D is ( 1 / 2 ) * G * T * T .
Same problem ! "the snippet contains no ACE syntax errors, but cannot be expressed in OWL/SWRL" !;
A very simple sentence gives "subject or object of this verb majkes an illegal reference" :
( ( 1 / 2 ) * G * T * T ) is an expression .
./ape.exe -guess -solo paraphrase -text "An expression is ( ( 1 / 2 ) * G * T * T ) ."
There is an n:expression X1.
There is something X2.
There is something X3.
The n:expression X1 is ( ( ( ( 1 / 2 ) * X2 ) * X3 ) * X3 ).
but ACE View says: "subject or object of this verb majkes an illegal reference" .
Same for :
An n : acceleration has-expression ( ( 1 / 2 ) * G * T * T ) .
Same for :
There is a time T .
There is an n : acceleration G .
An n : accelerated-movement has-expression ( ( 1 / 2 ) * G * T * T ) .
Using a personal noun is a hope :
There is a time T .
There is an n : acceleration G .
An n : accelerated-movement has-expression p :bla.
Indeed !
There is a time T .
There is an n : acceleration G .
An n : accelerated-movement has-expression p : acceleration-formula .
p : acceleration-formula has-formula ( ( 1 / 2 ) * G * T * T ) .
Alas! No error flagged, but the last line is not in the OWL at all.
There is a time T .
There is an n : acceleration G .
p : accelerated-movement has-expression ( ( 1 / 2 ) * G * T * T ) .
but ACE View says: "subject or object of this verb makes an illegal reference" . Same when removing the 2 first lines.
Note that using mass nouns for time and accelaration makes more sense:
./ape.exe -guess -solo drspp -text \
"There is some time T . There is some n : acceleration G . p : accelerated-movement has-expression ( ( 1 / 2 ) * G * T * T ) ."
[A, B, C]
object(A, time, mass, na, na, na)-1/6
object(B, acceleration, mass, na, na, na)-2/6
predicate(C, has-expression, named(accelerated-movement), expr(*, expr(*, expr(*, expr(/, int(1), int(2)), B), A), A))-3/6
Which gives different error messagesin ACE View, for acceleration and time:
"A reference to this noun either does not exist or is illegal."

Implemented these SWRL builtins in terms of CWM builtins, and for swrlb:substring, of RIF builtin: add, divide, equal, greaterThan, greaterThanOrEqual, lessThan, lessThanOrEqual, multiply, stringConcat, substring, subtract.

The test:
Simple integer datatype rule samples. Covers the following
cases:
hasDataValue1(?i, ?v) -> Result1(?i)
hasDataValue1(?i, "3"^^integer) -> Result2(?i)
hasDataValue1(?i, ?v), greaterThanOrEqual(?v, "0"^^integer) -> Result3(?i)
hasDataValue1(?i, ?v), equal(?v, 3) -> Result4(?i)
hasDataValue2(?i, ?v), lessThan(?v, "9"^^integer) -> Result5(?i)
hasDataValue2(?i, ?v), lessThanOrEqual(?v, "9"^^integer) , greaterThanOrEqual(?v, "7"^^integer) -> Result6(?i)
Tests the rules by creating instances with hasDataValue1 and hasDataValue2 with various values and combinations.
In fact the implementation in N3 is the same for IndividualPropertyAtom and DatavaluedPropertyAtom.

Downloaded sparql.lang from https://bugzilla.gnome.org/show_bug.cgi?id=583209
and added it in /usr/share/gtksourceview-2.0/language-specs/
I added there :
<property name="globs">*.n3</property> <property name="globs">*.nt</property> <property name="globs">*.ttl</property>
http://github.com/tialaramex/sparql-query/
It is a command line C tool; it compiles fine after installing packages :
libcurl-dev and libxml2-dev
Then I can start for example:
./sparql-query http://www4.wiwiss.fu-berlin.de/dblp/sparql \ 'SELECT * WHERE { ?s ?p ?o } LIMIT 10'

Implement RIF builtins in Drools : func:substring ; ask to Martin what are his plans for SWRL builtins, maybe what he has for Jess is already usable.
The icon for Java import should not be UML.
Drag'n drop from an N3 Source onto anything, and especially another EG window.
The suffix for SPARQL file should be also rq .
This query does not bring all the used classes from DPBL.
SELECT DISTINCT ?Concept WHERE {?x a ?Concept}
For instance, are missing:
dblp:InCollection dblp:Book
When saving the SPARQL, re-run the SPARQL query.
For projects taking some time to open (e.g. dpbl.n3p), an hourglass, or another feedback is necessary.
Manage memory usage by Euler and Drools; kill these when the system is begining swapping.
N3 prefix management:
Question asked to Jos:
I get an infinite loop with findall : it may be normal or not ...
I try to get all the Knowledge Base as a list of triples.
If I match one of ?S ?P or ?O in the antecedent, the infinite loop is avoided.
Otherwise , the e:trace is not printed at all .
{
# :starting :from ?S .
_:d e:findall ( {?S ?P ?O} {
?S ?P ?O.
?P log:notEqualTo log:implies .
?P log:notEqualTo e:findall .
} ?L ).
_:d e:trace ( "after e:findall" ?L ).
} => {
:allKB :asList ?L .
} .
Solution from Jos De Roo : an infinite *list* is avoided with an additional
?P log:notEqualTo :asList .
in the WHERE clause of the e:findall .

now the test suite passes
Extension points will not be added too often, but extensions will . So it is natural to think of the visitor design pattern. The element role in the visitor pattern will be played by Extension points, and the visitor role by extensions. To each Extension point, an event type is associated. ???????????
We should design the human visible outputs of EulerGUI:
We should design the intelligent extraction of data compatible with a query ; ask Martin what he thinks ... One idea is to limit a priori the depth of the extraction , for example in the FaceBook example it is 2 .
Note that RDF stores like Virtuoso that handle rdfs:subClassOf and rdfs:subPropertyOf could potentially with the same algorithms handle other transitive properties.

which really means :

This Drools does not compile:
rule "bb.n3 0" when $MLIST : TripleList( $MLIST_SIZE_ : size) from collect( $Triple_1 : Triple( $M : subject, predicate == "<http://simile.mit.edu/2004/09/ontologies/java#hasReturnType>", object == "\"\"" ) $Triple_2 : Triple( $hasType2 : subject, predicate == "<http://simile.mit.edu/2004/09/ontologies/java#hasType>", object == "\"urn:java:eulergui.project.Project\"" ) $Triple_3 : Triple( subject == $M, predicate == "<http://simile.mit.edu/2004/09/ontologies/java#hasParameter>", object == $hasType2 ) ) not( $Triple_4 : Triple( subject == "<http://eulergui.sf.net#answer>", predicate == "<http://eulergui.sf.net#is>", object == $MLIST ) ) then
Temporary conclusion : not feasible; maybe by turning the formula into a Drools rule; or by cascading "collect from" .

WIP : some architecture to think about,like:
- why and how to have the same thing both as Triple and Assignement
- should we present a single facade to the rule engine or several objects like now ?
we actually need a singleton for the EulerGUI application

Work on a short presentation in french of Déductions .
These Java implemented extensions; see also here for rule base implemented extensions: Include rules to extend EulerGUI behavior .
There were strange errors on my desktop, in TestReasonning , TestSwingGeneration , TestGenericGuiGeneration,

TODO
DONE
BUG FIX: Re-tested SPARQL GUI : create a new SPARQL source, in the project's directory or elsewhere
- In SWRLTranslator.projectLoaded() call new method Project.n3SourcesSafeCopy() to avoid ConcurrentModificationException, thrown in project examples/car_ace.owl.n3p
- also refactor to call Project.n3SourcesSafeCopy() in other places
http://www.w3.org/TR/owl2-profiles/#OWL_2_RL
N3SourcetoDrools.translate(IRDFIterator iterator) : better separate fact and rule processing, so that an error in Drools compilation does not prevent the fact processing to occur.
This will be good for tooltip in editor, for N3 sources mixing facts and rules .
Had a little conversation with kennyluck
http://people.csail.mit.edu/kennyluck/
on swig IRC
jvm, I totally refuse to create any newterms
update CHANGELOG for version 1.6
Installed al on my new laptop :).
OK:
replaceValue: retract [fact 0:1:195245781:-259644983:1:<http://exampleS.com#S> <http://exampleS.com#P> <http://exampleS.com#O> .
If I click on :name in person-app-spec.n3 in project person_import3.n3p , I get this query :
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . { <http://www.w3.org/2000/01/rdf-schema#label> rdfs:label ?DETAIL } => { <http://www.w3.org/2000/01/rdf-schema#label> rdfs:label ?DETAIL}.
what is needed is :
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . { <http://jmvanel.free.fr/ontology/examples/person#name> <http://www.w3.org/2000/01/rdf-schema#label> ?DETAIL } => { <http://jmvanel.free.fr/ontology/examples/person#name> <http://www.w3.org/2000/01/rdf-schema#label> ?DETAIL }.
Add Drools variables for each triplet, e.g. :
rule "rpo-rules-small.n3 0"
When
$ Triple_1: Triple ($ A: subject, predicate == "<http://www.w3.org/2000/01/rdf-schema#subClassOf>", $ B: object)
This will enable new features in the translation, like accessing to a list through another Triple matched in same rule.
Still working on lists in Drools, which are necessary to run the rules with OWL Jos generator application.
I update the example, adding the missing N3 ontologies. Now all what is missing are my predicates :( .

For plain N3 URI
In an N3 query, one can use substring-after ( tested in test/concatenationQ.n3 ) to get the list of possible completions . When substring-after returns an empty string, it is not a possible completion.
One would also like to have the details about the completed suggestions. To do that, one can combine this with implementation for ordinary tooltips.
For this a rule base can do all the job, returning e.g. triples like:
eg:completion <http:my.com/foo#bar> "Foo Bar: the property FooBar means ..." .
The object could be formatted in HTML.
For prefixed N3 URI
It is more complicated, but one can get a map of prefix associations from
ParserLink.getKnownURIPrefixes()
Then, if the string to complete does not begin with "<" , nor is a number, nor a blank node, and does not include a ":", the Known URI Prefixes can be used for completion.
If the string to complete does include a ":", then expand the prefix abbreviation, and use plain N3 URI algorithm.
Inactivated sources
Inactivated sources should also be searched by the N3 editor to provide labels and comments about the predicates and classes. To achieve that, one possible design is to have an extra KB containing all the inactivated sources. This extra KB will be serached the same way as the main user KB for labels and comments.
When we will integrate the rules to flag undeclared terms, the generated declarations will be added to Inactivated sources, as well as a list of classic ontologies like OWL, FOAF, etc , if they are effectively used.
What is the right word to designate one of the 3 parts of an RDF statement ? term ?
Yes, confirmation here: http://www.w3.org/TR/rdf-sparql-query/#sparqlBasicTerms (thanks to shellac on SWIG IRC ).
http://www.ostatic.org/jxml2owl
JXML2OWL Project is divided in two sub projects: JXML2OWL API, a library for mapping XML schemas to OWL Ontologies on the JAVA plaform. JXML2OWL Mapper, an easy to use standalone application with a graphical user interface using the JXML2OWL API.
How to bypass most of syntaxic sugar with CWM:
cwm --n3=lst examples/people_pets-small.n3
test/findall3.n3p
I simplified Olivier's example; see "Test Olivier's bus line example with ACE View ".
Note that putting "and A has location X" is an error, ACE View thinking that X is declared twice.
If a busLine B has a departureTown D ,
and B has an arrivalTown A ,
and D has a location X ,
and A has X
then the busLine B is a localBusLine .
Alas! Still useless variable creation:
arrivalTown(?x4) , busLine(?x1) , departureTown(?x2) , location(?x6) , have(?x1, ?x2) , have(?x1, ?x4) , have(?x2, ?x6) , have(?x4, ?x6) -> localBusLine(?x9) ∧ sameAs(?x1, ?x9)
Then, because the variable B was causing problem, I removed it :
If a busLine has a departureTown D
and the busline has an arrivalTown A
and D has a location X
and A has X
then the busLine is a localBusLine .
But the busline reference on line 2 was not understood, with an "anaphoric" message.
And, although this sentence looks "OWL-izable" , this is a wrong interpretation:
busLine and have some (departureTown and have some (location and inv(have) some (arrivalTown and inv(have) some busline))) subClassOf localBusLine
And the paraphrase clearly shows that this a wrong interpretation:
If a busLine X1 has a departureTown X2
and the departureTown X2 has a location X3
and a n : busline has an arrivalTown X4
and the arrivalTown X4 has the location X3
then the busLine X1 is a localBusLine .
Alas! If I add to the paraphrase above the intended X1 reference at line 3, we still have useless variable creation in the SWRL.
If a busLine X1 has a departureTown X2,
and the departureTown X2 has a location X3,
and X1 has an arrivalTown X4,
and the arrivalTown X4 has the location X3
then the busLine X1 is a localBusLine .
Permuting terms does not help:
If a busLine X1 has a departureTown X2
and X1 has an arrivalTown X4
and the arrivalTown X4 has a location X3
and the departureTown X2 hasthe location X3
then the busLine X1 is a localBusLine .
With a better domain modeling, we still have useless variable creation in the SWRL; the problem is related to this reasonning pattern, that is , this pattern of navigating the object properties and common variables :
If a busLine X1 has-as-departure a town X2,
and X1 has-as-arrival a town X4,
and the town X4 belongs-to a country X3,
and the town X2 belongs-to the country X3
then the busLine X1 is a nationalBusLine .
How to make object property predicates in ACE View : simply use the predicate as a verb: examples:
Ind172872104613704311 has-as-departure Toulouse .
Ind172872104613704311 has-as-arrival Paris .
Paris belongs-to France .
Toulouse belongs-to France .
France is a country .
Every town belongs-to one country .

I compared the situation with the RDF Parser, when also processing a relative URI.
In this case, this is where the URI resolving occurs for an RDF file:
Thread [main] (Suspended) RDFXMLParser$1(RDFParser).resolveIRI(String) line: 396 RDFXMLParser$1(RDFParser).getIRIFromResource(String) line: 450 RDFXMLParser$1(RDFParser).getNodeIDResourceResourceIRI(Attributes) line: 500 RDFParser$EmptyPropertyElement.startElement(String, String, String, Attributes) line: 966 RDFParser$PropertyElementList.startElement(String, String, String, Attributes) line: 853 RDFXMLParser$1(RDFParser).startElement(String, String, String, Attributes) line: 240 RDFXMLParser$1.startElement(String, String, String, Attributes) line: 63 SAXParserImpl$JAXPSAXParser(AbstractSAXParser).startElement(QName, XMLAttributes, Augmentations) line: not available SAXParserImpl$JAXPSAXParser(AbstractXMLDocumentParser).emptyElement(QName, XMLAttributes, Augmentations) line: not available XMLNSDocumentScannerImpl.scanStartElement() line: not available XMLNSDocumentScannerImpl$NSContentDriver(XMLDocumentFragmentScannerImpl$FragmentContentDriver).next() line: not available XMLNSDocumentScannerImpl(XMLDocumentScannerImpl).next() line: not available XMLNSDocumentScannerImpl.next() line: not available XMLNSDocumentScannerImpl(XMLDocumentFragmentScannerImpl).scanDocument(boolean) line: not available XIncludeAwareParserConfiguration(XML11Configuration).parse(boolean) line: not available XIncludeAwareParserConfiguration(XML11Configuration).parse(XMLInputSource) line: not available SAXParserImpl$JAXPSAXParser(XMLParser).parse(XMLInputSource) line: not available SAXParserImpl$JAXPSAXParser(AbstractSAXParser).parse(InputSource) line: not available SAXParserImpl$JAXPSAXParser.parse(InputSource) line: not available SAXParserImpl(SAXParser).parse(InputSource, DefaultHandler) line: not available RDFXMLParser$1(RDFParser).parse(InputSource, RDFConsumer) line: 139 RDFXMLParser.parse(OWLOntologyDocumentSource, OWLOntology) line: 88 ParsableOWLOntologyFactory.loadOWLOntology(OWLOntologyDocumentSource, OWLOntologyFactory$OWLOntologyCreationHandler) line: 165 OWLOntologyManagerImpl.loadOntology(IRI, OWLOntologyDocumentSource) line: 632 OWLOntologyManagerImpl.loadOntologyFromOntologyDocument(IRI) line: 590 LoadingOntologiesArgument.main(String[]) line: 41
So that, when ParsableOWLOntologyFactory.canLoad() does the checking of the import for an RDF file, the URI has already been resolved :
Thread [main] (Suspended) ParsableOWLOntologyFactory.canLoad(OWLOntologyDocumentSource) line: 115OWLOntologyManagerImpl.loadOntology(IRI, OWLOntologyDocumentSource) line: 627 OWLOntologyManagerImpl.loadOntology(IRI) line: 584 OWLOntologyManagerImpl.loadImports(OWLImportsDeclaration) line: 967 OWLOntologyManagerImpl.makeLoadImportRequest(OWLImportsDeclaration) line: 988 TPImportsHandler.handleTriple(IRI, IRI, IRI) line: 79 OWLRDFConsumer.handleStreaming(IRI, IRI, IRI) line: 1428 OWLRDFConsumer.statementWithResourceValue(String, String, String) line: 1392 RDFXMLParser$1(RDFParser).statementWithResourceValue(String, String, String, String) line: 520 RDFParser$EmptyPropertyElement.startElement(String, String, String, Attributes) line: 969 RDFParser$PropertyElementList.startElement(String, String, String, Attributes) line: 853 RDFXMLParser$1(RDFParser).startElement(String, String, String, Attributes) line: 240
The common part of the stacks for Turtle and RDF/XML is in blue.
As for the remedy, somehow the resolving that is done by this line 966 in RDFParser :
String objectIRI = getNodeIDResourceResourceIRI(atts);
should be factored and reused in the Turtle parser.
The real job occurs at line 381 in RDFParser :
protected String resolveIRI(String uri) throws SAXException {
Maybe this is the method to factor out in a new class
IRIResolver
, along with fields:
m_baseIRI , resolvedIRIs , uriCache
and method
public IRI getIRI(String s) {
Then where to reuse that new class IRIResolver in TurtleParser ?
Probably somewhere in the common blue part.
I think about the method getIRI() in OWLRDFConsumer , that is called for subject, predicate and object in statementWithResourceValue() :
private IRI getIRI(String s) {
This getIRI() uses a field iriProvider , that is null , at least when using a variant of the example LoadingOntologiesArgument .

X1 is an a:elapsed n:time .
Better sentence given by Norbert:
For all acceleration G for all elapsed-time T the distance that a mobile travels is 1/2*G*T*T.
This is not only simpler, but also relates the variables, and most importantly uses universal quantification.
But that does not work any more in ACE View .
Dialog with Norbert on the list:
I would have written your sentence as
For all acceleration G for all elapsed-time T the distance that a mobile travels is 1/2*G*T*T.
This is not only simpler, but also relates the variables, and most importantly uses universal quantification.
Agreed about that.
But I see that even the experts can guess imperfectly ACE text.
Your original sentence has no paraphrase at all :
./ape.exe -solo paraphrase -guess -text "For all acceleration G for all elapsed-time T the distance that a mobile travels is 1/2*G*T*T."
# ...
Looking at the DRS for a simpler sentence I saw that "all" with singular is for mass nouns only :
./ape.exe -solo drs -guess -text "For all acceleration there is a distance."
drs([], [=>(drs([A], [object(A, acceleration, mass, na, na, na)-1/5]), drs([B], [object(B, distance, countable, na, eq, 1)-1/11]))])
So I then tried :
./ape.exe -solo paraphrase -guess -text "For each acceleration G for each elapsed-time T the distance that a mobile travels is 1/2*G*T*T."
If there is an n:acceleration X1 then if there is an n:elapsed-time X2 then a n:distance X3 is ( ( ( ( 1 / 2 ) * X1 ) * X2 ) * X2 ) and a n:mobile v:travels the n:distance X3.
which is not too bad, but the relation with the mobile is not semantically correct.
After 15 mn of trials and errors, I found this to be satisfying with ACE :
./ape.exe -solo paraphrase -guess -text "For each mobile M for each acceleration G for each elapsed-time T the distance that M travels during the elapsed-time T is 1/2*G*T*T ."
If there is a n:mobile X1 then if there is an n:acceleration X2 then if there is an n:elapsed-time X3 then a n:distance X4 is ( ( ( ( 1 / 2 ) * X2 ) * X3 ) * X3 ) and the n:mobile X1 v:travels the n:elapsed-time X3 the n:distance X4.
The transitive verb travels has two complements, but one is of type distance , and the other of type elapsed-time, which is good for me.
Finally, I adapted this sentence to ACEView by transforming intransitive verbs into transitive ( e.g. travels-during ) , and removing one of the complements of travel.
But this brings the feared message: "the snippet contains no ACE syntax errors, but cannot be expressed in OWL/SWRL" .
And no more message :( !
For each mobile M for each n : acceleration G for each elapsed-time T there is a distance D such
that M travels-during the elapsed-time T ,
and D is ( 1 / 2 ) * G * T * T .

In EulerGUI we need to add other data sources, like Java source code (and other programming languages), Javadoc, various databases (JDBC, XML-DB, no-SQL stores), AI sources (KIF, CLIPS, TPTP, ...). Right now we plan Java source code and Javadoc. This interface is enough to model a source factory :
interface N3SourceFactory { N3Source createFromURI( URI uri, URI baseUri ) throws N3SourceException; }
Then we need to to track all places where , e.g. , N3SourceFromRDF is created, and replace the call to constructor with a loop on all the N3SourceFactories . Plus a piece of code to setup all the N3SourceFactories; or use eclipse extension point mechanism?
We can't go on doing ad-hoc developments for each new data source. The problematic is the same for inference engines.
We got to have some plugin architecture. I will have a look at OSGi .
Extension points
One thing that is not clear is the relationship of eclipse style "extension points" with OSGi. Also the annoying thing is that the interfaces at an extension point are not enforced, and not documented in the plugin.xml files. Another annoying thing is that there are 3 kinds of configuration: plugin.xml, MANIFEST.MF, and properties files. For example I had a look at documentProviders Extension Points Reference ;
documentProviders Extension Points Reference on help.eclipse.org .
It's also clear from this discussion on protege wiki that the implemented interfaces are not enforced :
http://protegewiki.stanford.edu/index.php/PluginAnatomy#Adding_New_Plugin_Types
In this example what the infrastructure brings is the ability to find all instances of the Extension point through this class:
org.protege.editor.core.plugin.AbstractPluginLoader
It seems that at one moment Matthew Horridge used the JPF (Java Plug-in Framework) .
Protégé plugins
To kill two birds with one stone, I'll have a look at Protégé plugins :
http://protegewiki.stanford.edu/index.php/PluginAnatomy
Another question is : will Protégé Felix plugins work with Maven
http://felix.apache.org/site/apache-felix-maven-bundle-plugin-bnd.html ?
Does anybody know how to make a tab for P4.1 using Java in Eclipse?
There is a web site here [1] that talks about how to make a tab plugin for Protege 4.1. Usually there is no reason to write any code. A tab plugin developer will usually only need to write code to implement any new views that show up in his tab. The development of a view plugin is described in [2].
These pages do describe things at the level of raw java. They do not discuss the pointing and clicking and the many user preferences that are involved in setting up an ide. The ide construction is described elsewhere [3]. In particular for working with Protege 4.1 (recommended for new plugins) in eclipse, people seem to think that the [4] page is very easy to use.
I would not say that [1,2] are unix specific; I have seen windows users who are quite proficient on the command line.

I translated into N3 rules OWL subclass assertions involving anonymous classes into N3 rules , e.g .

It WORKS !
Mail sent to Martin, Jos, Eulergui-users, ...
Hi all
This morning I attacked the translation of complex OWL expressions into N3 rules. I took the people and pets example from aceview Examples .
From there I translated an OWL subclass assertion involving anonymous classes into N3 rules , e.g.
[from ACE View example] Every person that has-as-pet at least 3 things is an animal-lover.
in Manchester syntax:
person and ( has-as-pet min 3 thing ) SubClassOf animal-lover
In N3:
[ a :Class;
rdfs:subClassOf people_pets_ace:animal-lover;
:intersectionOf (
people_pets_ace:person
[
a :Restriction;
:minCardinality "3"^^xsd:nonNegativeInteger;
:onProperty people_pets_ace:has-as-pet ] ) ].
Translation in N3 logic:
{ ?X a person.
_:d e:findall (?P {?X has-as-pet ?P} ?Y).
?Y math:memberCount ?C.
?C math:greaterThan 2 .
} => { ?X a animal-lover }.
The EulerGUI project for this case is :
http://deductions.svn.sourceforge.net/viewvc/deductions/n3_new/owl-subclass-assertions-to-rules.n3p
The plan is now :

http://semwebcentral.org/projects/swrl-test-suite/
swrl-ex3-n.n3 : swrl:DatavaluedPropertyAtom
swrl-ex4-n.n3 : swrl:builtin
Upon opening the project, the translation from SWRL to N3
logic occurs, and this adds to the project the N3 document
dl-safe.owl.rules.n3
, which contains the translated N3 rules.
the temporary file name should be kept and content rewritten when re-launching inference engine
REGRESSIONS:
argument to Euler is not kept in the Project file;
Window title is not always updated (new Window+Save as...)
the tooltip in case af N3 syntax error is not there anymore
Now that rules SWRL work thanks to Jos, I see that automatic translation in EulerGUI, works only when a project file is already present.

The model and rules are populated, e.g. from these sentences :
Everything that is read by a white-van-man is a tabloid.
Every man that drives a van that is a white-thing is a white-van-man.
Every white-van-man is a man that drives a van that is a white-thing.
these OWL ontology items are created:
ALAS !!!!!!!!
None of the 5 examples in the ACE View documentation has any rule !

http://www.eclipse.org/albireo/
http://attempto.ifi.uzh.ch/aceview/#Examples
Pending a solution of the problem with the RDF format for lists in SWRL from Protégé 4.1 ( mail to Jos), I can still test SWRL files by converting them to N3 with CWM.
So I take the sentence that was enhanced by Kaarel:
If a user U knows a person X, and knows a person Y, and X is not Y,
and X knows Z, and Y knows Z, and Z is not U
then Z is-a-proposed-friend-for U.
I put this in the ACE View of Protégé 4.0.2, and then I get this in the rule view :
person(?x2) , person(?x4) , user(?x1) , Thing(?x7) , know(?x1, ?x2) , know(?x1, ?x4) , know(?x2, ?x7) , know(?x4, ?x7) , differentFrom(?x2, ?x4) , differentFrom(?x7, ?x1) -> is-a-proposed-friend-for(?x7, ?x1)
Wonderful !
The OWL+SWRL is eulergui/examples/facebook-aceview.owl . The classes person and user, the Object Properties know and is-a-proposed-friend-for, are also recorded in the ontology.
Then I try the import in EulerGUI.
Converting the OWL/RDF to N3 with CWM :
cwm --rdf facebook-aceview.owl --n3 > facebook-aceview.owl.cwm.n3
It worked the first time !!!!
ns1:support ns1:rules <http://eulersharp.svn.sourceforge.net/viewvc/eulersharp/trunk/2003/03swap/owl-differentFrom.n3>. {?t0 a facebook-aceview:person. ?t1 a facebook-aceview:person. ?t2 a facebook-aceview:user. ?t3 a owl:Thing. ?t2 facebook-aceview:know ?t0. ?t2 facebook-aceview:know ?t1. ?t0 facebook-aceview:know ?t3. ?t1 facebook-aceview:know ?t3. ?t0 owl:differentFrom ?t1. ?t3 owl:differentFrom ?t2} => {?t3 facebook-aceview:is-a-proposed-friend-for ?t2}.
ACE View Remarks:
EulerGUI Remarks:
?t3 a owl:Thing
ns1:support ns1:rules
...
should be used by EulerGUI to add the indicated rules to the
current project; See next paragraph.Suppose that, like in the "proposed friend" rule just above,
owl:differentFrom
appears in the antecedent side of a rule. Then
it seems reasonable to add to the project the OWL rules from Euler that can
produce triples with owl:differentFrom
. That is, we will add to
the project all the OWL rules from Euler having owl:differentFrom
in the consequent side.
In the reverse logical direction, if owl:differentFrom
appears
in the consequent side of a rule, we will add to the project all the OWL rules
from Euler having owl:differentFrom in the antecedent side.
I updated the official version on Subversion: newproject.n3p.n3
Due to current problems with OWL imports of relative URI's with Protégé 4.1, to test this file one has to convert it in RDF:
cwm newproject.n3p.n3 --rdf > newproject.n3p.n3.owl

I played with the new toy that I made [1] ; I create SWRL rules with Protégé 4.1, and I try to run them with EulerGUI,
And guess what?
It does not quite work: an SWRL file created with Protégé 4.1 does not output anything with my SWRL to N3 logic translator.
This is a matter of RDF format for a list.
Compared to the file I developed with [2] , there a format difference with the recent Protégé (see the same file saved with Protégé 4.1 , attached as dl-safe-protege41.owl ).
This Protégé 4.1 format for rules (OWL/RDF plus SWRL), is converted into N3 within EulerGUI using Jena 2.6.2 ( attached as dl-safe-protege41.owl.eulergui.n3 ). Note that the N3 rewriting of this last document by CWM is markedly different ( attached as dl-safe-protege41.owl.cwm.n3 ), and that one does output the expected thing with my SWRL to N3 logic translator.
After some rule debugging , I boiled down the issue to the following test.

Inspired from http://www.daml.org/2003/11/swrl/examples.html , I entered into Protégé 4.0.2 this SWRL rule :
Artist(?x)
, artistStyle(?x,?y)
, Style(?y)
, creator(?z,?x)
-> workStyle(?z,?y)
Alas , the SWRL => N3 translation does not output anything !!!!!!!!
The problems seems to be :
rdf:parseType="Collection"
in the one from http://owldl.com/ontologies/dl-safe.owl
, and now it uses rdf:first
and rdf:rest
;Indeed, if I run my SWRL => N3 translation with the N3 produced by CWM, it works and produces :
{?t0 a ex:Artist. ?t1 a ex:Style. ?t0 ex:artistStyle ?t1. ?t2 ex:creator ?t0} => {?t2 ex:workStyle ?t1}.
The stuff from dl-safe.owl that works with EulerGUI (and the Jena RDF==>N3 conversion) has this structure:
<swrl:head rdf:parseType="Collection"> <swrl:ClassAtom> <swrl:classPredicate rdf:resource="#BadChild" /> <swrl:argument1 rdf:resource="#x" /> </swrl:ClassAtom> </swrl:head>
Here swrl:ClassAtom is a so-called "Typed Node Element" from the RDF spec.
According to the sectiin about Syntax
parsetype Collection , the rdf:parseType="Collection"
syntax
is equivalent to the rdf:first
and rdf:rest
syntax.

Translator from SWRL to N3 logic: implemented swrl:IndividualPropertyAtom in consequent and
swrl:DifferentIndividualsAtom in antecedent
I tested the new Translator from SWRL to N3 logic implemented in N3 logic, with a pipeline project : swrl-n3-rules-big.n3p . So now one can translate the SWRL and launch the translated N3 rules in one EulerGUI run, composed of two Euler Eye runs. So here is the global answer:
:bc a :BadChild. {?t0 a :GoodChild} => {?t0 a :Child}. {?t0 a :BadChild} => {?t0 a :Child}. {?t0 a :Grandchild. ?t0 :sibling ?t1. ?t0 :hates ?t1} => {?t0 a :BadChild}.
One definitely needs a post processing project, because the rules are generated in the query of the first run, and so cannot be part of the first run.
I will make a snapshot.
TopBraid 3.3 : Converting UML Files to RDF via Java/EMF Objects and SPARQLMotion
[jena-dev] ANN: ARQ 2.8.3
Group: com.hp.hpl.jena
Artifact: arq
Version: 2.8.3
See EulerGUI project: transitive_closure.n3p
This is more adapted to Euler engine than RETE engines like Drools. Indeed, with RETE it would populate heavily the Working Memory, whereas it is just a query. I'm not sure if it could be made into a Drools query.
{ :starting :point ?SP. ?SP ?P ?Z } => { ?SP :forwardConnection ?Z. }. # main rule { ?X :forwardConnection ?Y. ?Y ?P ?Z } => { ?X :forwardConnection ?Z. }.
The query:
{ _:d e:findall ( ?Y_ { :starting :point ?START. ?START :forwardConnection ?Y_} ?CLOSURE_REPEAT ). ?CLOSURE_REPEAT e:distinct ?CLOSURE. # TODO flatten the result } => { :rules :hasClosure ?CLOSURE. }.

an alternative to using the instanciator technology;
useful for the internal KB and generated applications
cf EulerGUIServer. I looked if there is a more of less standard way of wrapping a pre-cooked SPARQL query as a simple HTTP GET request. It would have the query name, and possibly parameters that would be replaced in the query before running it. Here is discussion for parameterized queries for SPARQL : http://www.w3.org/2009/sparql/wiki/Feature:Parameters .
There is also a proposal for Query_by_reference that proposes a query like:
/sparql?query-uri=http://www.example.org/queries/test.rq
Altogether we will accept such HTTP GET queries (urlencoded of course):
?query-uri=./myQuery.n3&myParam1="string value"&myParam2=<http://site.com/stuff1>
The relative URL ./myQuery.n3 is the query URL exactly how it appears in the EulerGUI project.
Note the difference between plain strings (myParam1) and URI parameters (myParam2).
Variables ?myParam1 and ?myParam2 in the source of the N3 query will be replaced before running the query. Behind, we leverage on the corresponding feature of Drools.
add a tab with all the messages, and a scrolling panel for important messages (both statistics and messages recapitulation, and warnings and errors)
there is already a class TemporaryFrame, modeless and disappearing quickly, for important messages
agree on the RDF vocabulary;
implementation: replace the class XMLSchemaCatalog and can either add thisCatalog to the internal KB, or use a Jena Model
implementation: we listen to the end of the current window ProjectGUI to start the next project. We should not have to change ProjectGUI.
<> owl:import <foo.n3> :app xml:lang "fr"
[from ACE View example] Every person that has-as-pet at least 3 things is an animal-lover.
in Manchester syntax:
person and ( has-as-pet min 3 thing ) SubClassOf animal-lover
In N3:
[ a :Class; rdfs:subClassOf people_pets_ace:animal-lover; :intersectionOf ( people_pets_ace:person [ a :Restriction; :minCardinality "3"^^xsd:nonNegativeInteger; :onProperty people_pets_ace:has-as-pet ] ) ].
Translation in N3 logic:
{ ?X a person. _:d e:findall (?P {?X has-as-pet ?P} ?Y). ?Y math:memberCount ?C. ?C math:greaterThan 2 . } => { ?X a animal-lover }.
Note: the reversed class inclusion also exists in this example, and also needs to be translated:
people_pets_ace:animal-lover a :Class; rdfs:subClassOf [ a :Class; :intersectionOf ( people_pets_ace:person [ a :Restriction; :minCardinality "3"^^xsd:nonNegativeInteger; :onProperty people_pets_ace:has-as-pet ] ) ] .
Suppose that, like in the "proposed friend" rule,
owl:differentFrom
appears in the antecedent side of a rule.
Then it seems reasonable to add to the project the OWL rules from Euler
that can produce triples with owl:differentFrom
. That is, we
will add to the project all the OWL rules from Euler having
owl:differentFrom
in the consequent side.
In the reverse logical direction, if owl:differentFrom
appears in the consequent side of a rule, we will add to the project all
the OWL rules from Euler having owl:differentFrom in the antecedent
side.

Reactivate ApplicationKB; correct error when populating the KB with project data
See "EulerGUI ideas"
In the editor, it should be good to have a tooltip explaining the use of predicates like:
e:optional
In fact, this explaination can be taken from the N3 definition of the Euler predicates, by this N3 query:
e:optional ?P ?V .
The Euler specific builtins are defined in N3 in log-rules.n3 . Cwm Builtins are defined in N3 in log.n3 .
These ontologies, plus RDF, RDFS, and OWL can be predefined. The rest is expected to be in the project.
Implementation
The implementation would use log:semantics
and
log:includes
(see log.n3 ) and other advanced
builtins that are not yet in Drool/N3 engine.
Here is a sketch of a rule to populate a tooltip for the editor.
{ :current_editor :current_predicate ?CURRENT_PREDICATE . ?CURRENT_PREDICATE :definedByURI ?ONTOLOGY. # e.g. <http://www.w3.org/2000/10/swap/log.n3> ?ONTOLOGY log:semantics ?LOG . ?LOG log:includes { ?CURRENT_PREDICATE ?P ?V } . } => { :current_editor :tooltip ( ?P ?V ). # another rule will call Java method setTooltip() }.
For performance, log:semantics
would use an application-wide
(or system or local area -wide) cache.
The key would be the URL. But what should it cache? A local file ? No. A set of Triple objects? A ParserLink with its underlying AST for N3 ?
Use a Drools KB for cache ? Why not ? But we don't need rule capability here. A TDB local store? Better, and one can use SPARQL to query the content. Then we would use a named graph for each entry (or group of entries). Is there already some code doing that for TDB?
QUESTION ASKED on the Jena list.
ADDED monday 29: this needs more reflection. There are 2 possible implementations:
log:semantics
and log:includes
must be implemented in Drool/N3 engine.:current_editor :current_predicate ?CURRENT_PREDICATE
It seems that the current state of the liaison between the KB and Java is not quick enough for a nice user experience. Indeed the tooltip implementation should subscribe to the mouse motions, which entails many events. Reasoning about software is still a good principle, but for this feature the reasoning should happen at design time, not a runtime.
Anyway, in both variants, we need a predicate or method
eg:definedByURI
that gives the actual URL location of the ontology
defining a property or class. For example, eg:definedByURI
will
assert:
<http://www.w3.org/2000/10/swap/log#conjunction> eg:definedByURI
<http://www.w3.org/2000/10/swap/log.n3>
Although one can write some heuristics, it seems that there is also a need
for a table of correspondance eg:prefixIsdefinedByURI
that will be
used in the implementation of predicate or method eg:definedByURI
. For example, eg:prefixIsdefinedByURI
will assert:
<http://www.w3.org/2000/10/swap/log#> eg:prefixIsdefinedByURI
<http://www.w3.org/2000/10/swap/log.n3>
I wonder if this has already been written. I would say: yes.
Olivier says:
A priori, ontology imports already specify more or less from what place may come a definition of class or property.
Otherwise, no salvation except a service like or sindice or watson.
It 's much the same as for predicates.

swrl-n3-rules.n3 : fix the fully substituted triple; now we get this (also applied the simplification due to latest Euler revision 3352 ) :
( {:x :sibling :y. :x :hates :y} ((:x _:x_1) (:y _:y_1)) ) :substitutedFormula {_:x_1 :sibling _:y_1. _:x_1 :hates _:y_1}
yap -l /home/jmv/src/eulersharp/2006/02swap/euler.yap \ -g main -- --nope --pass /home/jmv/src/eulergui/examples/parents.n3
The substitution results can be recovered by finding all the triples with object an empty (substitution) list among all the :substituteVariableList stements :
_:sk3 :print ({:x :sibling :y} :substituteVariableList ((:x _:sk4) (:y _:sk5))).
_:sk13 :print ({_:sk1 :sibling :y} :substituteVariableList ((:y _:sk11))).
_:sk16 :print ({_:sk1 :sibling _:sk11} :substituteVariableList ()).
Now I need to recover the fully substituted triple:
{_:sk1 :sibling _:sk11}
from the initial non substituted triple and the substitution list
{:x :sibling :y} :substituteVariableList ( (:x ?X)(:y ?Y) ) .
A possible design is to change the predicate "signature" by changing the subject into a list whose first item is the actual (recursive) argument, and second item is the original arguments (in this case the initial non substituted triple, plus the subtitution). This second item will be kept unchanged during recursion.
( {:x :sibling :y} ( {:x :sibling :y} ( (:x ?X)(:y ?Y) ) ) ) :substituteVariableList ( (:x ?X)(:y ?Y) ) .
So I call the design pattern "add an item in the list that will be kept unchanged during recursion".
Thus the predicate "signature" in rules will be :
(?STAT ?INVARIANT) :substituteVariableList ?L .
Then the query to recover the fully substituted triple from the initial non substituted triple ?T0 and the substitution list ?L is :
(T0 ?L) substitutedTriple ?TSUBST.
implemented as:
{ ( ?STAT (?STAT ?L) # INVARIANT ) :substituteVariableList ?L . _:d e:findall ( ?STAT_ {(?STAT_ (?STAT ?L) ) :substituteVariableList ()} ?TSUBST ). } => { (?STAT ?L) substitutedTriple ?TSUBST. }.
At last !
I could do recursive variable substitution:
from {:x :sibling :y} :substituteVariableList ( (:x ?X)(:y ?Y) ) . to: ({_:sk1 :sibling :y} (:y _:sk12)) :variableSubstitution {_:sk1 :sibling _:sk12}
# TODO <<<<<<<
# variable substitution of ?V by ?VT in a triple ?T == {?S ?P ?O}
#** What: :substituteVariableList - substitution of a list of variable substitutions ?L in a triple
# @subject an RDF statement
# @object list of variable substitutions, e.g. ( (:x ?X)(:y ?Y) )

Martin O'Connor pointed me to his SWRL Language FAQ: What are DL-Safe SWRL Rules?
Now copied in the EG Manual.
Some work for the new embedded (a.k.a. internal) rule engine ( this engine is only aware of the user actions, the user configuration, and the projects ) :
A KB is maintained which contains all the triples in the Project; this is the one that is already used for inferencing, and it is already resident in memory. Let's call it "user data KB".
Some work for the "user data KB" rule engine :
this implies launching a special rule base that analyses user rules and generates a skeleton for the properties and classes declarations not declared anywhere;
a rule base already exists, which warns of undeclared properties: see deductions/n3_new/model-rules-coherence.n3p
for recursion it needs the builtin log:parsedAsN3
(see
CwmBuiltins ; this built-in lacks today in the Drools N3 engine )
( could also be done with a Java callback )
we need the association between row numbers and columns on the Statements;
to navigate from a resource to its definition, we assume it is declared in the project, and since the "user data KB" contains all triples of the project, a simple rule and query can do the job

Here is Protégé right after clicking on "Run Jess" in bottom middle (and clicking on "OWL+SWRL-> Jess" before ):
When cliking on "Jess->OWL" , the inferred triples are added to the current ontology.
The buttons "OWL+SWRL-> Jess" and "Run Jess" are just one button in EulerGUI (with choice of several inference engines). This is a good thing.
The button "Jess->OWL" has no equivalent in EulerGUI. Currently, to achieve that, one could :
I propose to add one more button that will automatize that. The button would be at extreme top right, and bear this logo:

It will add to the projet a file named

. This way, the user will have no file name to choose. And, contrary to
SWRLTab in Protégé 3.4, the inferred triples will not be mixed with "pure"
asserted triples. A variation, with even less user click ( always better ! ),
is to add inconditionally the file named
<project_name>-<engine_name>-result.n3 after an inferrence run, but
with a non-activated status .
And for the users wanting to merge several ontologies, she can use CWM from
EulerGUI with --pipe
.
Deactivated in ProjectGUI : addWindowListener(exitOnLastWindowClosed);
Being a listener on the main Frame, it cannot react to other frames events.
Moreover, it seems best to rely on the dispose-window default window close operation :
"When the last displayable window within the Java virtual machine (VM) is disposed of, the VM may terminate. See AWT Threading Issues for more information."
See WindowConstants.DISPOSE_ON_CLOSE
Solved the long lasted problem: Tests in error: test_person_import(eulergui.gui.TestSwingGeneration)
- put disposeWindows() *both* in setUp() and tearDown()
- probably the cleaning with Project, ProjectSequence, and SimplifiedURI helped
Several tests were broken since revision 1289, were the Project URL string (field url) was set as a file:// URL for file projects;
this led to errors in SimplifiedURI were field baseDirectory can (alas!) be an URL or a file path.

[1] is a good starting point. In particular [2] will help you write some simple example plugins. [1] includes how to setup Protege in several development environments. In particular eclipse is nice because it includes OSGi support and makes plugin development that much easier.
If you are just starting, work with Protege 4.1 rather than Protege 4.0.*.

Commited into eulergui/html/project_ontology.html
For the EulerGUI Integrated Development Environment we define a general notion of project for ontology plus data and rules .
Indeed it is for a particular project, but it is a strength to have a specific project which demonstrates the concept.
Also we seek the broadest applicability, and to reuse as much vocabulary as possible.
Having an XMLEncoder file was convenient at first, but it means that the implementation Java classes are in the project persistance file, which is very unflexible! Also, the setters are called when too little is known, namely in our case the base URL of the project.
And of course, since we strongly believe that N3 is the exchange format that will enable universal data exchange, we must have an N3 project file!
Here is a sample of the current input file:
<java version="1.6.0_15" class="java.beans.XMLDecoder"> <object class="eulergui.project.Project"> <void property="n3Query"> <object class="eulergui.project.N3Source"> <void property="URI"> <string>./maven-pom.n3</string> </void> </object> </void> <void property="sources"> <void method="put"> <string>http://eulergui.svn.sourceforge.net/viewvc/eulergui/trunk/eulergui/pom.xml</string> <object class="eulergui.inputs.N3SourceFromXML_Gloze"> <void property="URI"> <string>file:/tmp/translation-2727048603323236665.n3</string> </void> <void property="otherFile"> <string>http://eulergui.svn.sourceforge.net/viewvc/eulergui/trunk/eulergui/pom.xml</string> </void> </object> </void> </void> </object> </java>
Like Protégé 4, we reuse the OWL Ontology as a wider Project object.
Note that, AFAIK, Protégé silently converts into OWL an RDF Schema. Currently in EulerGUI this is not implicit.
Another difference is that in EulerGUI, currently, all ontology, data and rules are in imported documents, whereas in Protégé (that is, OWL) ontology, data and rules can be in the main document or in imported documents, and so on recursively.
In Protégé rules (necessarily SWRL) are embedded in an ontology (probably also in imported ontologies ?); in EulerGUI rules (necessarily N3 logic for now) are embedded in an N3 source.
The core EulerGUI "Project" ontology
@prefix : <http://eulergui.sf.net/ontology/project.owl#>. @prefix owl: <http://www.w3.org/2002/07/owl#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix xsd: <http://www.w3.org/2001/XMLSchema#> . :RDFImport a owl:Class ; rdfs:label "RDF Import" ; rdfs:comment """RDF import means that a non RDF source like plain XML, XMI, etc is converted in a well defined way into an RDF/N3 document.""" . :hasRDFImport a owl:ObjectProperty ; rdfs:domain owl:Ontology ; rdfs:range :RDFImport ; rdfs:label "has RDF Import" ; rdfs:comment """In addition to its regular content, an owl:Ontology has RDF Imports that aware applications add to the regular content.""" . :hasURL a owl:DatatypeProperty ; rdfs:domain :RDFImport ; rdfs:range xsd:anyURI ; rdfs:label "has an (absolute) URI" ; rdfs:comment "a dereferenciable URI for the RDF import" . :hasRelativeURL a owl:DatatypeProperty ; rdfs:domain :RDFImport ; rdfs:range xsd:string ; rdfs:label "has a relative URI" ; rdfs:comment """a relative URI for the RDF import, relative to the base URI of the importing Ontology. An RDFImport has either a relative URI, or an (absolute) URI, but not both.""" . :isActivated a owl:DatatypeProperty ; rdfs:domain :RDFImport ; rdfs:range xsd:boolean ; rdfs:label "is this RDF source activated during inferencing?" ; rdfs:comment """It is convenient to have data sources belonging to the project just as reference or trial.""" . :hasQuery a owl:DatatypeProperty ; rdfs:domain owl:Ontology ; rdfs:range xsd:anyURI ; rdfs:label "has an (absolute) URI" ; rdfs:comment "a dereferenciable URI for the project's N3 query" . # TODO N3 searches, plain N3, other formats .....
In addition to the above core EulerGUI "Project" ontology, we are considering two designs for expressing the format of imported documents (plain XML, XMI, etc) :
<http://www.w3.org/XML/1998/namespace>
for plain XML .
Possibly there could be a further hint for polymorphic formats like XML and XMI, but EulerGUI is able to "pre-parse" an XML document to know the XML Schema associated to the root, and for XMI it relies on the extension .uml or .xmi, .mof, etc .
Advantages | Inconvenients | Comments | |
use JenaBean | does read and write | possibly not flexible; introduces yet another dependency | |
use the EulerGUI Java instantiator | reuses EulerGUI technology; very flexible; possibly apply validation rules | does only the N3 ==> Java objects conversion;
for the reverse need to populate an RDF database through observer Design Pattern, but we plan to do that anyway (called the "conscience" of the application) |
We'll do that; see below migration path |
Here is a sample of the N3 rules. We apply the N3 logic design pattern "annotate the existing objects".
RDFImport resources are mapped to objects of type Java class N3Source.
@prefix java: <http://java.sun.com/class#> . @prefix javam: <http://java.sun.com/method#> . { ?ONTO a owl:Ontology .
} => { ?ONTO a java:eulergui_project_Project . ?ONTO java:url ?ONTO . }. { ?ONTO a owl:Ontology . ?ONTO :hasRDFImport ?IMPORT. ?IMPORT :hasFormat <http://www.w3.org/XML/1998/namespace> . } => { ?IMPORT a java:eulergui_project_N3SourceFromPlainXML . ?ONTO javam:addN3Source ?IMPORT . }. # TODO N3Query, N3 searches, isActivated; other formats .....
The steps , that will keep the application working:

Installed SWRL Jess Tab following the instructions:
http://protege.cim3.net/cgi-bin/wiki.pl?SWRLJessInstall
The SWRL Jess Tab is the extension to the SWRLTab allowing rules execution.
This uses the SWRL Bridge. The bridge provides the infrastructure necessary to incorporate rule engines into Protege-OWL to execute SWRL rules.
Using this ontology with SWRL from the Pellet site:
http://owldl.com/ontologies/dl-safe.owl
Alas !!!!!!!!!!!!!
Succesful execution of rule engine.
Number of inferred axioms: 0
So I try the "official" SWRLTab example:
http://protege.cim3.net/file/pub/ontologies/family.swrl.owl/family.swrl.owl
WIP . See above the follow-up: Trying SWRL tab (SWRLTab) in Protégé 3.4.3.
Not without trials and errors, I wrote this ACE sentence that
represents a rule that a site like FaceBook might use for friend
proposals:
If the current-user C knows a person X and a person Y
and X is different from Y
and X knows Z
and Y knows Z
and Z is different from C
then Z is a friend-proposal for C .
The first version had commas at every end of line that make it clearer
for the human reader, but ACE dislikes them :( .
Then ACE View says:
The snippet contains no ACE syntax errors, but cannot be expressed in OWL/SWRL .
And the ACE Feedback panel says twice about "person" :
A reference to this noun either does not exist or is illegal.
( hard to read BTW, because the columns are too narrow, and there is
no way to select the message, and no tooltip )
Then I removed "person" like this :
If the current-user C knows X
and Y
and X is different from Y
and X knows Z
and Y knows Z
and Z is different from C
then Z is a friend-proposal for C .
Then the ACE Feedback panel says again twice the message, but this
time about "something" :
A reference to this noun either does not exist or is illegal.
The problem might be too many "and" .
Since I have (AFAIK) no way in ACE to parenthesize things, I remove some and's :
If the current-user C knows X
and the current-user C knows Y
and X is different from Y
and X knows Z
and Y knows Z
and Z is different from C
then Z is a friend-proposal for C .
I hoped that using variables would ease the analysis. But no !
Now there are 3 errors:
- Subject or Object of this verb makes an illegal reference. --> for
"know" and "be"
- Adjectives are not supported.
I give up for now, and I 'll read Kaarel's thesis .
I got an answer from Norbert E. Fuchs <fuchs@ifi.uzh.ch> : it works !
If a current-user C knows a person X
and knows a person Y
and X differs-from Y
and X knows a person Z
and Y knows Z
and Z differs-from C
then Z is a friend-proposal of C .
Now the issue is with differs-from ; in N3 logic it is log:notEquals ; in pure SWRL there is probably nothing. Maybe in ACE DRS or in SWRLTab there is something.
:) In fact there is swrlb:notEqual
; see SWRL Submission : 8.1. Built-Ins
for Comparisons .
So now the issue is with differs-from ; I saw nothing about equality in the documentation. How can equality be expressed in ACE and in DRS ?

W3C Working Draft 16 June 2009
http://www.w3.org/TR/dcontology/
In protege's SWRL Factory FAQ
http://protege.cim3.net/cgi-bin/wiki.pl?SWRLFactoryFAQ
I found the location of the swrl definition in owl
http://www.daml.org/rules/proposal/swrl.owl
for Protégé; in fact the original proposal for SWRL has another format for rules, related to RULEML .
Currently I obtain this:
{_:sk1 a :Grandchild. _:sk1 :sibling _:sk2. _:sk1 :hates _:sk2} => {_:sk1 a :BadChild}.
Replaced this:
{ _:d e:findall ( ?A {?RULE :n3_antecedent_has ?A} ?LA ). _:d e:findall ( ?C {?RULE :n3_consequent_has ?C} ?LC ). ?LA log:conjunction ?FA . ?LC log:conjunction ?FC . } => { ?FA => ?FC }.
Protégé 4.0.2 is in a worse shape than I thought; it's impossible to import the FOAF ontology!

EulerGUI is a turntable for Semantic Web, and beyond (UML, ECore, XML Schema), with N3 logic rules for querying, graph transform, validation. It can be used both for software engineering and business domain reasoning. Complementary to Protégé, Pellet and Jena, it can be used for learning Web Semantic and rule-based design.

Right
Mary v:likes all n:chocolates.
Mary likes all chocolates.
Mary likes some chocolates. ==> Paraphrase : Mary likes at least 2 chocolates.
Mary likes each of the chocolates.
Mary likes a chocolate.
Mary likes no chocolate.
In fact what one really means with "Mary likes chocolate" is , in the countable sense :
Every chocolate is a food. Mary likes every chocolate.
or, in the mass sense :
Every chocolate is a food. Mary likes some chocolate.
or
Every chocolate is a food. Mary likes all chocolate.
In fact there is problem with the last 2 sentences ; chocolate is "countable" by first phrase, and "mass" by the second.
The wrong phrases violate the rules for noun phrases, see "2.1.3 Mass Noun Phrases" or "2.1.2 Plural Countable Noun Phrases" in :

I made a test for a small rule from this example:
http://owldl.com/ontologies/dl-safe.owl
Grandchild(?x) , hates(?x, ?y) , sibling(?x, ?y) -> BadChild(?x)
Here is a sketch of a translation of SWRL to N3 logic, implemented in N3 logic .
http://eulergui.svn.sourceforge.net/viewvc/eulergui/trunk/eulergui/examples/swrl-n3-rules.n3
This is just a sketch, because only swrl:ClassAtom and swrl:IndividualPropertyAtom criteria are translated .
The result is :
{:x rdfs:type :Grandchild} => {:x rdfs:type :BadChild}.
{:x :sibling :y} => {:x rdfs:type :BadChild}.
{:x :hates :y} => {:x rdfs:type :BadChild}.
What is wrong right now is that it generates several implies (=>) blocs, in fact one per criterium on the consequent side . But I hope it can be arranged, stay tuned .

gloze.base
parameterThere are things to know for the drop (RDF to XML conversion) with Gloze.
The gloze.base
parameter is "tolerant" when the "root resource"
is <> : e.g. adding this is mandatory, but any URL can be
provided, e.g. :
-Dgloze.base=file://foo.com
This should be modified: the gloze.base parameter should not be mandatory.
But when the "root resource" is not <> , the right
gloze.base
parameter is mandatory.
When the input file has root resource with a file URL, one must be cautious.
For example with this root resource:
<file:///tmp/translation-57.n3>
this does not work:
-Dgloze.base=file:/tmp/translation-57.n3
One must use this URL form:
-Dgloze.base=file:///tmp/translation-57.n3
Apparently this is related to the Java bug in URL implementation : "URL class definition voilates RFC 1738 Section 3.10"

Jena URI ressources from the Jena API have file:///
, contrary
to the JDK implementations of classes File, URL, URI.
Morewover, when reading an RDF file, the root resource must start with
file:///
, and gloze.base
also. When reading an RDF
file, Gloze tolerates a single slash in the resource URI for root in the file.
So it's better to stick to triple slashes when authoring or generating an RDF
for XML translation.
With the very simple N3 file based on the XHTML Schema (see below), I got that stack :
Thread [main] (Suspended (exception NullPointerException)) attribute.toXML(Element, Resource, Set<Statement>, Context) line: 326 attributeGroup.toXML(Element, Resource, Set<Statement>, Context) line: 140 attributeGroup.toXML(Element, Resource, Set<Statement>, Context) line: 136 complexType.toXML(Element, Resource, int, Set<Statement>, boolean, Context) line: 258 complexType.toXML(Element, Resource, int, Set<Statement>, Context) line: 246 element.toXML(Node, RDFNode, Context) line: 632 Context.toXML(Document, Resource) line: 221 Gloze.drop(Resource) line: 747 Gloze.drop(Model, URI) line: 724 Gloze.rdf_to_xml(URL, File, URI, Model) line: 524 Gloze.rdf_to_xml(URL, String) line: 560 Gloze.runGloze(String[]) line: 821 Gloze.main(String[]) line: 774
It was simple to apply some defensive programming.
Here a simple N3 file based on the XHTML Schema. This rather complex Schema is important in applications.
@prefix : <http://example.com#>.
@prefix html: <http://www.w3.org/1999/xhtml#>.
<> html:html _:html.
_:html html:body :body .
_:html html:head :head .
:head html:title "bla" .
With there arguments:
/home/jmv/src/eulergui/test/xhtml.n3 http://www.w3.org/1999/xhtml http://www.w3.org/2002/08/xhtml/xhtml1-transitional.xsd
I got this rather long stack that is hard to understand. What is clear is that a Literal "bla" is cast as a Resource.

I also found the origin of a strange warning message :
[ WARN] - 2010-02-06 11:14:22,226 [AWT-EventQueue-0] com.hp.gloze
(BeanLoader.java:load:102)
cannot load http://www.w3.org/1999/xhtml#div
This is due to a div element , but not in the input of Gloze, in the XML Schema, inside an <xsd:documentation> . In this particular case, that is not in the main XSD :
http://www.w3.org/2002/08/xhtml/xhtml1-transitional.xsd
but in
http://www.w3.org/2001/xml.xsd ,
that is imported.
Gloze should ignore the content of <xsd:documentation> .
I modified BeanLoader to avoid the message.
I'm testing "drop" on a N3 file like this, corresponding to an XHML document :
@prefix html: <http://www.w3.org/1999/xhtml>.
_:root html:html _:html.
_:html html:body _:body.
_:body html:p _:sk1.
_:sk1 html:span :NealStephenson.
_:sk1 html:span "a".
_:sk1 html:span :scifiWriter.
First my code for "smart drop" was not good when the XML rood node is an RDF blank node ( _:sk0 ).
I did a correction in Gloze.rdf_to_xml() , but that was not enough. I got the "classical" error in method drop(Resource resource) :
[ WARN] - 2010-02-06 12:41:02,431 [main] com.hp.gloze (Gloze.java:drop:736)
drop: no schema mapping for resource: file:/home/jmv/src/eulergui/test/xhtml.n3
[ WARN] - 2010-02-06 12:41:02,435 [main] com.hp.gloze (Gloze.java:drop:739)
because no properties, is gloze.uri correctly defined?
I will let that aside <<<<

Hi ! I have a multi-valued property that is a LinkedHashMap<String, Something> ,

this does not fit well with the standard indexed property;
is there some good practice, or some support classes , similar to java.beans.PropertyChangeSupport ?

Working on the specification of EulerGUI Server:
https://sourceforge.net/apps/trac/eulergui/wiki/EulerGUIServer. That wiki is not very agreable :( .
I wonder if there is a more of less standard way of wrapping a pre-cooked SPARQL query as a simple HTTP GET request.
It would have the query name, and possibly parameters that would be replaced in the query before running it. Here is discussion for parametrized (or parameterized ?) queries for SPARQL :
http://www.w3.org/2009/sparql/wiki/Feature:Parameters
http://www.w3.org/2009/sparql/wiki/Feature:Query_by_reference
that proposes a query like:
/sparql?query-uri=http://www.example.org/queries/test.rq

for Bernard , add the OK label on button that was missing in popup URL Chooser
When creating a new SPARQL query, with a non-existing file, the result of the query is put in a new /tmp file, but it was not available through the leftmost button.
NOTE: I "simply" redo the layout, because the action for the leftmost button is not easily accessible. I could pre-create the /tmp file, or have an observer for changes on the N3 source. The RDF case is implemented differently :( .
The main reference is:
http://eulersharp.sourceforge.net/README : "Just running Euler via RESTfull webservice" .
I unzipped the Euler distribution in
/home/jmv/apps/Euler-2009-12-18
, then
cd /home/jmv/apps/Euler-2009-12-18
chmod u+x eye
First I ensure that eye is in the path : this runs fine:
~/bin/eye --nope http://www.agfa.com/w3c/euler/medic.n3 \ --query http://www.agfa.com/w3c/euler/medicF.n3
I simply created a script ~/bin/eye containing:
( cd /home/jmv/apps/Euler-2009-12-18 ./eye $* & )
But this was useless for the server.
I simply started the class euler.Codd
in the Euler
distribution's directory /home/jmv/apps/Euler-2009-12-18 , with this argument
:
--port 8088
Then I can run from Firefox the URL-encoded version of the Euler run above :
Using REST Client ( chrome://restclient/content/restclient.xul ) , or even Firefox, one can send this (the URL-encoding is done before sending):
http://localhost:8088/.eye --nope http://www.agfa.com/w3c/euler/medic.n3 --query http://www.agfa.com/w3c/euler/medicF.n3 |
I wonder whether there is a way to output plain N-Triples (no prefixes).

Now, I should add a server that wraps the class Project from EulerGUI ...
More precisely, it should wrap a Drools Working Memory that can keep the user data for the duration of the session. The data persistence needs more thinking, as the first version will be a pure expert system.
But what requests will this server accept? Several possiblities:
insert or delete an single triple, given by parameters subject, predicate, object
this is not particularly interesting, neither on the calling nor callee side; we will either use next option, N-Triples message sent by an HTTP PUT message:
this will replace options 1 and 2 ( even delete via predicates kb:replace )
this will work much like a SPARQL query, except that the syntax is N3 logic for query, and N3 or N-Triples for result;
TODO in EulerGUI Drools engine:

Sesame 2.3.0 was released on December 1, 2009 . They write:
First of all, all of SPARQL's functionality is now also available in SeRQL.
but it's not clear whether Sesame 2.3.0 is fully compliant with SPARQL.
It is not clear what is the difference between Joseki and TDB, as they both support the SPARQL Protocol and the SPARQL RDF Query language.
I should announce EulerGUI 1.4 on jena-dev@yahoogroups.com .
Does not work with SWI Prolog Version 5.6.64 included in Ubuntu:
prolog_ide( open_navigator( '.' )). false.
EulerGUI is a GUI for RDF, N3 and rules, open source in Java.
The main new feature in this release is plain XML import and export, based on XML Schema and a reasonable mapping between RDF and plain XML. The following XML Schema are hard coded (but you may ask for more): XHTML, SVG, MathML, XForms, XSLT, WSDL, DocBook, XBRL, Maven, Dublin Core in XML, UBL (from Oasis), KML (geography).
There is also a new N3 / RDF source: query from SPARQL services (using ARQ 2.8.2 from Jena project ) .
The OWL reasoner Pellet is integrated in a simple way, and shows OWL class tree for each source.
We now test the GUI at the functional level . It is happiness to see all these use cases that turn on their own quickly ! It now runs in about 3 minutes, but it should even be reduced by parallelizing the Drools compilations, which takes several seconds each. Jemmy is a test library for Swing and SWT. Jemmy has been used for years by the NetBeans team. The tests are written in Java, and JUnit tests added to the EulerGUI test set. These EulerGUI tests include the use cases of the Manual of Deductions Project : generation of applications from sources on Internet in languages N3, OWL, RDFS, UML, and eCore.

EulerGUI is a GUI for RDF, N3 and rules, open source in Java.
The preceding announce for EulerGUI on this list was :
https://mailman.stanford.edu/pipermail/protege-owl/2009-September/012051.html
I said that the rule language is N3 logic . N3 logic is similar to SWRL in its semantics, but the syntax is similar to the body of SPARQL queries.
But I forgot to say that, contrary to SWRL, the predicates and classes do not need to be declared beforehand. There are 4 rule engines available, including one 100% Java based on the famous RETE engine Drools .
EulerGUI has a notion of project, including many kinds of sources that participate in the inference launch: N3, RDF, OWL/RDF, XMI/UML, plain XML, results of SPARQL queries.
The Euler Prolog engine can use rules in N3 logic for most of OWL concepts, see documents in owl-*.n3 in
http://eulersharp.svn.sourceforge.net/viewvc/eulersharp/trunk/2003/03swap/?sortby=file#dirlist

Dialog on the Protégé list:
http://article.gmane.org/gmane.comp.misc.ontology.protege.owl/31431
To model in OWL a route through several cities, I do not know what is good practice: use rdf:List , or rdf:Seq , or something else .
You are thinking at the rdf level of abstraction and not the owl level. If you use rdf:List or rdf:Seq then you will have an owl full specification. Reasoners generally will not work and it is very likely that the meaning of the ontology will not be the same for each reader.
Nick Drummond has given several presentations where he has described how to do what you want in OWL and exactly what you can say in OWL. A quick google search gives the powerpoint presentation [1] where he describes the approach. There is also an ontology that you can find here [2].

Thanks a lot Timothy .
So what I did is import the OWL List ontology from the generic URL
http://www.co-ode.org/ontologies/lists/list.owl
and particularize the class OWLList as a list of cities, by two owl:Restrictions :
Itinerary equivalentTo
hasContents only City
and OWLList
and isFollowedBy only Itinerary
As exemplified in :
http://www.co-ode.org/ontologies/lists/examples/motif-example.owl
What I regret is that the OWL List ontology is not a "standard" ontology , but it's not a big deal.
Further to the references that Timothy provided, there is a paper describing the list pattern:

R2ML is a comprehensive and user-friendly XML rule format.
From this RIF Implementations list , I see that Euler implements RIF ! :) , using external RIF/XML->N3 translator . But where is this external translator ?
This works, but it is just the test for RIF builtin predicates and functions:

I installed ACE without problem from the distribution. Then I can run commands e.g. (can also run on the the APE Web client without installing anything ) :

[] [A, B, C, D, E, F] object(C, customer, countable, na, eq, 1)-1/3 property(A, premium, pos)-1/7 predicate(B, be, C, A)-1/4 object(F, product, countable, na, eq, 1)-1/12 property(D, luxury, pos)-1/16 predicate(E, be, F, D)-1/13 => [G, H, I, J, K] object(K, discount, countable, na, eq, 1)-1/21 object(G, customer, countable, na, eq, 1)-1/24 object(H, product, countable, na, eq, 1)-1/30 predicate(I, buy, G, H)-1/26 modifier_pp(J, for, G)-1/22 predicate(J, be, K, real(7.5))-1/31
This last one coming from the RuleML tutorial is interesting because,
calling ./ape.exe -solo paraphrase
on it, one sees that the input
is wrong. After some trials and errors I got this:
./ape.exe -solo paraphrase -guess -text "If a customer C is premium and the customer C buys a product P and P is luxury then the discount is 7.5% for P applied to C ." If a customer X1 is a:premium and the customer X1 buys a n:product X2 and the n:product X2 is a:luxury then a n:discount is 7.5 applied to the customer X1 for the n:product X2.
Note also that here "the discount" triggers this message on the APE Web client :
The definite noun phrase 'the discount' does not have an antecedent and thus is not interpreted as anaphoric reference, but as a new indefinite noun phrase.
Note also that here "applied" is interpreted as an adverb. This variant is propably better:
./ape.exe -solo drspp -guess -text \ "if a customer C is premium and the customer C buys a product P and P is luxury then a discount of 7.5% for P is applied to C ." [] [A, B, C, D, E, F, G] object(A, customer, countable, na, eq, 1)-1/3 property(B, premium, pos)-1/8 predicate(C, be, A, B)-1/5 object(D, product, countable, na, eq, 1)-1/17 predicate(E, buy, A, D)-1/13 property(F, luxury, pos)-1/24 predicate(G, be, D, F)-1/21 => [H, I, J] object(H, discount, countable, na, eq, 1)-1/29 relation(H, of, real(7.5))-1/30 modifier_pp(J, for, D)-1/32 property(I, applied, pos)-1/37 predicate(J, be, H, I)-1/34 modifier_pp(J, to, A)-1/38

I had a look at a RuleML example: http://ruleml.org/translator/exa/hunger.ruleml .
The various modularized parts of the XML Schema for RuleML are here:
For instance, datalog.xsd includes by schemaLocation 8 other modules. The hierarchy of models is detailed here:
http://ruleml.org/modularization/model/ruleml_m12n_09_uml_06-09-01.svg , which mainly says:
Binary-->datalog-->hornlog-->dishornlog-->folog
There is a PDF document called Content Models for RuleML .
http://ruleml.org/indesign.html : this design document seems to have a historical value...
http://www.ruleml.org/papers/tutorial-ruleml.html : this tutorial document is indeed the best one to understand the XML structure of RuleML.
See also the Cover pages on ruleML
I was able to compile and launch the translator from ACE to RuleML. It calls the Web service for ACE (that parses the Controlled English), and prints the XML for RuleML in a JPanel. The class DRSParser (made with JavaCC from the grammar DRSParser.jj , described in thesis "TRANSLATOR: A TRANSlator from LAnguage TO Rules", by David Z. Hirtle, April 12, 2006 ) parses the DRS from ACE, and directly generates the XOM XML elements obeying the XML Schema for RuleML. The translation rules are described in the JavaCC grammar. The crucial lines are:
queryString = QUERYBASE + PARAMS + URLEncoder.encode(aceText, "UTF-8"); nu.xom.Document doc = builder.build(queryString); String drs = doc.getRootElement().getFirstChildElement("drs").getValue(); java.io.Reader r = new java.io.BufferedReader(new java.io.StringReader(drs)); Element as = null; // parse DRS with DRS parser if (parser == null) parser = new DRSParser(r); else parser.ReInit(r); as = parser.Start();
I'm trying to figure out how I can export an ACE rule base (in DRS, discourse representation structure ) as N3 logic. RuleML is just one possible intermediary. Directly using the ACE tools in SWI Prolog might be better. There is in fact some Prolog sources for SWRL in utils/ , but no command line predicate ...
I tried to re-use the DRS XML, by converting it with EulerGUI and Gloze. Alas the order of the 2 DRS tags inside Implication is not kept in the conversion, and there is no XSD available for DRS. I could follow the same path, but with the XML RuleML translation provided by the translator from ACE to RuleML .
There is a short "Rosetta stone" between RuleML and N3, called "N3 in Object-Oriented RuleML".

I changed the Ant of Gloze:
<property name="java.debuglevel"
value="source,lines,vars"/>
because vars was missing !!!!!!!! The debugger showed only the arguments, not the local variables.
On december 2nd, I tested Gloze with Ant (see Testing my modifications in Gloze ). Now I can't do ant compile anymore (but did I really run it ?) ! But ant test still runs !
I applied this recipe :
"Debug Maven using Standalone Maven install"
from http://docs.codehaus.org/display/MAVENUSER/Eclipse+Integration, that is:
First of all you need to get corresponding Maven projects into the Eclipse workspace.
To debug Maven standalone Maven CLI you can set the following environment variable:
MAVEN_OPTS=-Xdebug -Xnoagent -Djava.compiler=NONE \
-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000
Then start Maven as usual and attach remote debugger to Maven process on port 8000 using Eclipse's "Remote Java Application" configuration.
To that I added in pom.xml an ingredient from the next recipe:
<plugin> <artifactId>maven-surefire-plugin</artifactId> <configuration> <forkMode>never</forkMode> </configuration> </plugin>
Gloze "drop" (RDF to XML conversion) now works on an N3 file, but a special one, starting with :
<> kml_:kml [ a kml_:KmlType ; kml_:Placemark ...etc ...
This way the <> resource stands for the URI of the N3 file.
I discovered the role played by the gloze.base
parameter . In
the case of drop, this means the URI of the resource that will be converted to
the XML root element. Indeed in a general RDF graph there is no such thing as a
root.
I expected (naively) that Gloze was able to detect in a general RDF graph this "root" resource. But it does not, as it is not trivial.
So it has to be either given to Gloze, through the System Property
"gloze.base
" , or computed from the RDF graph and some information
related to the XML Schema. The XML root element(s) for a given Schema is
probably something that will have to be set in configuration (because an XML
Schema does not specify a root element). Then to find the RDF statement that
will be converted to the XML root element, one has to iterate on the
statements, finding one that has the right predicate ( kml_:kml
in
the example above). So we could add in Gloze this method to set the RDF
predicate of the "root" resource corresponding to the XML root:
void setRootPredicate(String root);
The root RDF predicate would also be associated to a System Property
"gloze.root
" .
Now at 1pm, it only works with eclipse; in fact there was 2 errors in file URI management:
file:/a/b
instead of
correct file:///a/b
/a/b/./c
But now from Maven I get this ( from eclipse it works in the same directory ) :
[ WARN] - 2009-12-17 13:28:56,408 [AWT-EventQueue-1] com.hp.gloze (Gloze.java:drop:663) drop: no schema mapping for resource: file:///home/jmv/src/eulergui/test/kml2.n3 [ WARN] - 2009-12-17 13:28:56,409 [AWT-EventQueue-1] com.hp.gloze (Gloze.java:drop:671) because no matching property: http://www.opengis.net/kml/2.2#kml
In fact, given the message, and the fact that this particular Schema for KML does not declare the root element <kml>, it seems normal that it does not work.
The strange effect with Maven it certainly due to a mixture of static and non-static stuff in Gloze. Before me, Gloze was never tested a a reusable object.
After even more investigations, an EulerGUI test project with 2 sources, one N3 and one RDF, both using the KML vocabulary from the Schema, shows the same problem when exporting the second RDF source [on 21st could not reproduce that].

Currently it does not work.
As a side task I need to find a small XML Schema, preferably non trivial and useful. I try KML, a geographical Schema used in Google Earth, with this pair XML namespace + Schema location:
http://www.opengis.net/kml/2.2" http://schemas.opengis.net/kml/2.2.0/ogckml22.xsd
To test, I can click on XML export on a small KML document (eulergui/test/kml.xml) imported in EulerGUI. The question is: how can I find the pairs XML namespace + Schema location corresponding to an N3 /RDF documents ( typically coming from a rule engine ) ?
So from this N3, how can I find the pairs XML namespace ?
@prefix kml_: <http://www.opengis.net/kml/2.2#> . @prefix kml: <http://www.opengis.net/kml/2.2> . <file:/tmp/translation-5764596566461002629.n3> kml_:kml [ a kml_:KmlType ; kml_:Placemark [ a kml_:PlacemarkType ; kml_:Point [ a kml_:PointType ; kml_:coordinates ("-74.006393,40.714172,0"^^xs_:string) ] ; kml_:description "New York City"^^xs_:string ; kml_:name "New York City"^^xs_:string ] ] .
So we see that Jena RDF to N3 translator has created two N3 prefixes for
KML. Note that there is a loss a information here, but I don't think that Gloze
keeps the correspondance between the RDF predicate kml_:kml
and
the XML elements they come from. Note that the root <kml>
element is not in the XML Schema for KML
.
KML reference on code.google.com
So we need to get access to the list of N3 prefixes, see if some of them match the XML namespaces in namespace2schema0 in XMLExport.java, and add the pair XML namespace + Schema location to the Gloze arguments.
In fact this is what XMLExport.selectSchemataFromProject()
does
:) . But for an N3 source coming from RDF, method
N3Source.getKnownURIPrefixes()
returns an empty set. In fact, even
for an N3 source, this method returns an empty set when the Drools N3 engine
has not been launched, i.d. when the N3 parser has not run yet. So I'm adding a
"lazy" N3 parsing to method N3Source.getKnownURIs()
.
DONE

Need to change that in Triple, because loading factsTriples.xml currently is broken .

With latest ARQ 2.8.2 from Jena these language constructs seem not to work:
I have a look in the ARQ ChangeLog to see what would be a replacement. I found this interesting page with the solution:
http://jena.sourceforge.net/ARQ/negation.html
In fact, as exemplified in
http://www.w3.org/TR/rdf-sparql-query/#func-RDFterm-equal
these operators work only inside a FILTER clause:
# This query finds the people who have multiple foaf:name triples: PREFIX foaf: <http://xmlns.com/foaf/0.1/> SELECT ?name1 ?name2 WHERE { ?x foaf:name ?name1 ; foaf:mbox ?mbox1 . ?y foaf:name ?name2 ; foaf:mbox ?mbox2 . FILTER (?mbox1 = ?mbox2 && ?name1 != ?name2) }
A Project with an N3 source throwing an exception at restore during prepare() does not prevent the project from being loaded; the N3 source is shown with a rose background and a tooltip showing the exception.
TODO : EulerGUI Manual: review recent features: SPARQL, XML import and export
The Parser4J N3 parser in EulerGUI is quite stable now. So, shorten the test time, I added this in 2 places in the Parser4J tests in EulerGUI:
// possibility to bypass long Parser4J tests: String runTests = System.getProperty("PARSER4J_TESTS"); if( "no".equals(runTests) ) return;
Now one can run the tests like this:
mvn -DargLine="-DPARSER4J_TESTS=no" test
I got an answer to my question on the Jemmy list:
https://jemmy.dev.java.net/servlets/ReadMsg?list=users&msgNo=55
It works ! Note that I used to have close request sent by Jemmy to Firefox (bug of Jemmy, of my tests, of Firefox or of X-Windows ?). Of course this trick of running inside a second X server removes also this problem.
Now with this incantation I run all the important tests in 2 minutes !
DISPLAY=:1 mvn -DargLine="-DPARSER4J_TESTS=no" \
--no-plugin-updates --offline test
All this is nox documented in the Manual .

Functional (Jemmy) tests:

Jester - Test your tests with Jester
Quote from the site:
Jester finds code that is not covered by tests. Jester makes some change to your code, runs your tests, and if the tests pass Jester displays a message saying what it changed.
The changes are very simple, like changing true to false, but the "succeded" changes point to missing tests, or in some cases to unnecessary code. Here is how I launched Jester. Because it re-builds after each change, it is quite slow, so I just ran one test and provided only one source class for changes
java -jar /home/jmv/apps/simple-jester120/simple-jester.jar \ -classpath target/eulergui-1.4-SNAPSHOT-jar-with-dependencies.jar:\ /home/jmv/.m2/repository/junit/junit/3.8.1/junit-3.8.1.jar \ -buildCommand "mvn -Dtest=unif.InstanciatorTest test" \ -source src/main/java/unif/Instanciator.java -shouldShowProgressDialog true ... 196 mutations survived out of 246 changes. Score = 21 took 43 minutes
This means that only 21% of the mutations were caught by the tests. Actually in this package only one file is relevant : Instanciator.java , but a package directory could have been given instead, e.g. :
-source src/main/java/unif/
As an example, here is the result of Jester; a copy of the original source files as ".html" pages, with all the changes Jester made that did not cause the tests to fail shown in red, and the code it changed shown with a line through it : Instanciator.html
Work in progress:
mvn -Dtest=eulergui.gui.TestGenericGuiGeneration \ -Ddemo=active test
Luc worked towards actual persistence. For now, it only runs in memory, but already uses the P* modified Joafip ollections.
The Subversion incantation to copy sources from one branch to another:
cd ~/src/eulergui
svn cp examples/simplest.n3* \ https://eulergui.svn.sourceforge.net/svnroot/eulergui/branches/eulergui-joafip/examples/
It is nice for demos to keep the GUI active for interactions after scenario is played.
TODO
Add to one test the EulerGUI features: display class hierarchy with Pellet, plain XML as N3 source, SPARQL query, export as Drools, export as XML;
and also the generated aplication features: click on object properties, round trip with use N3 file, ...
I realize that the Jemmy API is like a scripting API for any Swing application. I should open the Euler GUI Manual and write the script for all the features.

I update Jemmy 2 test to include the main Déductions use cases: generate application from URL : N3 , OWL , RDFS , UML , and eCore documents.
While doing that, I met the annoying problem that the RDFS URL is long to download (in a separate thread), but the Drools engine does not wait.
DONE:
NOTE: cv.n3p, with older Swing infrastructure swing2.n3p does not produce a window (no JFrame generated)
Added a call to Thread.join() ; also throw a timeout exception if the URL is too long to download.

Download sources and build
cd ${HOME}/src
svn co https://joafip.svn.sourceforge.net/svnroot/joafip/trunk/joafip/ ant -f buildjar.xml build
Deploy on local repository with pom.xml (just for testing) :
cd ${HOME}/src/joafip mvn deploy:deploy-file -Dfile=dist/joafip-2.2.2.jar \ -Durl=file:${HOME}/.m2/repository/ \ -DpomFile=${HOME}/src/joafip/pom.xml
To upload on remove repository, just change the url pamameter, and add repositoryId:
mvn deploy:deploy-file -Dfile=dist/joafip-2.2.2.jar \
-Durl=sftp://web.sourceforge.net/home/groups/j/jo/joafip/htdocs \
-DrepositoryId=repository.joafip.sf.net \ -DpomFile=${HOME}/src/joafip/pom.xml
The repository Id refers to the following content in <HOME_DIRECTORY>/.m2/settings.xml :
<settings> <servers> <server> <id>repository.joafip.sf.net</id> <username>jmvanel,joafip</username> <password>???</password> </server> </servers> </settings>
This allows to completely automatize the upload.
One can also add this at the end of the pom.xml, but I think it's facultative :
<repositories> <repository> <id>repository.joafip.sf.net</id> <url>http://joafip.sourceforge.net</url> </repository> </repositories>
On cygwin you should install:
ant, maven2, sftp, sun-jdk
I asked what they think on the Abbot list .
cd ${HOME}/src svn co https://abbot.svn.sourceforge.net/svnroot/abbot/abbot/trunk \ abbot cd ${HOME}/src/abbot/ ant jar
I don't want to pollute my remote Maven repository for these trials. So I first did this to upload on the local Maven repository the jar from the Abbot Sourceforge project:
ARTIFACT=abbot
VERSION=1.0.3-SNAPHOT
mvn deploy:deploy-file \ -Dfile=${HOME}/src/abbot/build/${ARTIFACT}.jar \ -Durl=file:${HOME}/.m2/repository/ \ -DgroupId=net.sourceforge.abbot \ -DartifactId=${ARTIFACT} \ -Dversion=${VERSION} -Dpackaging=jar ARTIFACT=costello # mvn deploy:deploy-file ...
I have no pom.xml at all; but it's OK, and Maven answers:
[INFO] [deploy:deploy-file {execution: default-cli}] Uploading: file:/home/jmv/.m2/repository//net/sourceforge/abbot/costello/1.0.2-SNAPHOT/costello-1.0.2-SNAPHOT.jar 599K uploaded (costello-1.0.3-SNAPHOT.jar) [INFO] Retrieving previous metadata from remote-repository [INFO] repository metadata for: 'artifact net.sourceforge.abbot:costello' could not be found on repository: remote-repository, so will be created [INFO] Uploading repository metadata for: 'artifact net.sourceforge.abbot:costello' [INFO] Uploading project information for costello 1.0.2-SNAPHOT
Then I go further and use the pom.xml for Abbot I made from this discussion on the Abbot list :
http://old.nabble.com/Maven-2-POM-ts20489891.html ,
following this Maven page: deploying-with-customed-pom.html
In fact there are 2 artifacts: the core Abbot, and the recorder GUI, Costello, depending on Abbot. For EulerGUI we will need both.
mvn deploy:deploy-file \ -Dfile=${HOME}/src/abbot/build/costello.jar \ -Durl=file:${HOME}/.m2/repository/ \ -DpomFile=${HOME}/src/abbot/pom.xml
Note that the groupId, artifactId, version and packaging informations are automatically retrieved from the given pom.
mvn deploy:deploy-file \ -Dfile=${HOME}/src/abbot/build/abbot.jar \ -Durl=file:${HOME}/.m2/repository/ \ -DpomFile=${HOME}/src/abbot/pom_abbot.xml
Then I can test the local Maven installation for Abbot, adding this in pom.xml :
<dependency> <groupId>net.sourceforge.abbot</groupId> <artifactId>abbot</artifactId> <version>1.0.3-SNAPHOT</version> <scope>test</scope> </dependency>
It seems to work.
Of course, I have another problem. My tests were recorded with Costello, and depend on some absolute positions.

bddbddb stands for BDD-Based Deductive DataBase. It is an implementation of Datalog, a declarative programming language similar to Prolog for talking about relations. What makes bddbddb unique is that it represents the relations using binary decision diagrams (BDDs). BDDs are a data structure that can efficiently represent large relations and provide efficient set operations.
Third, it makes program analysis accessible, and dare I say it, actually fun.
I probably made the wrong move when upgrading to Jena 2.6.2,because it is incompatible with Pellet rc7 . So I have to wait for the next release of Pellet, says Thorsten Möller.

10-Open-Source-Companies-to-Watch : : lessons to draw ?
http://www.voelter.de/conferences/index.html
This is the first branch in EulerGUI, so I must create the directory branches first:
cd ~/src/eulergui_test2/eulergui ls # tags trunk mkdir branches svn add branches svn commit branches svn copy https://eulergui.svn.sourceforge.net/svnroot/eulergui/trunk/eulergui \ https://eulergui.svn.sourceforge.net/svnroot/eulergui/branches/eulergui-joafip
Now to work on that branch, go to a fresh location like ~/src/ , and type :
svn co https://eulergui.svn.sourceforge.net/svnroot/eulergui/branches/eulergui-joafip cd eulergui-joafip mvn install mvn eclipse:eclipse eclipse &
Then create an eclipse project from directory eulergui-joafip.
Alas today (saturday!) the Maven site http://jena.hpl.hp.com/repo/ for Jena is awfully slow.
There is a new discussion in French :
Virtuoso versus Sesame - versus joafip
To integrate into Drools we would need a DAO design pattern, or the possibility to plug a specific implementation of ObjectStore (or SingleThreadedObjectStore).
http://joafip.sourceforge.net/
At last ! added EulerGUI here: http://semanticweb.org/wiki/EulerGUI
I made a new discussion group in French for projects Déductions and EulerGUI:

I'm on Ubuntu 9.04, architecture x86_64.
Download the source from here:
http://sourceforge.net/projects/virtuoso/files/
I took the 6.0.0 version, that has no release notes :( . The licence is GPL v2. Then, according to the README, I missed these packages :
sudo apt-get install flex bison gperf libssl-dev
Otherwise this is very classic:
export CFLAGS="-O2 -m64" ./configure make sudo make install
Alors je peux lancer le serveur (toujours suivant le README) :
cd /usr/local/virtuoso-opensource/var/lib/virtuoso/db sudo chown $USER . /usr/local/virtuoso-opensource/bin/virtuoso-t -f &
I can then open the web admin interface : http://localhost:8890/conductor/
The main entry point for the documentation is: http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/
In the doc. , I find a page on "RDF Insert Methods in Virtuoso".
Since I have not created any other user, I upload an OWL file as dba with an HTTP PUT :
curl -T PeriodicTable.owl http://localhost:8890/DAV/home/dba/rdf_sink/PeriodicTable.owl -u dba:dba
The trouble is that this OWL file was uploaded as a binary, as it was sent with Content-Type application/octet-stream. You can see this by clicking on WebDAV Browser.
Let's try a .rdf file :
curl -T foaf1.rdf http://localhost:8890/DAV/home/dba/rdf_sink/foaf1.rdf -u dba:dba
Then this is recognized as RDF (Content-Type application/rdf+xml).

Open Source; in Python; easily instable on Ubuntu. Alas on a fresh database several actions lead to an internal error. The families are builtin, but completion does not always occur. Could not make the report work. Note: I'd love to make a similar applicatoin with an RDF database and my GUI generation techniques.
For XForms (and XHTML?) output, I think about using the other, more abstract, layer in my rules stack, "gui_generic.n3" (see also Supporting ontologies).

See "Déductions & XForms"
Here is the kind of XML that must be generated in the end of the tool chain (after the RDF to XML conversion by Gloze) :
<body> <xf:textarea ref="MyTextValue"> <xf:label>Note:</xf:label> </xf:textarea> </body>
Since XML elements and attributes correspond through Gloze to RDF / N3 predicates, the kind of N3 that must be generated is (with all blank nodes explicited):
_:n1 xhtml:body _:n2. _:n2 xf:textarea _:n3. _:n3 xf:ref "MyTextValue". _:n3 xf:label "Name:".
Currently, the corresponding fragment of the generic GUI (actually very Java-oriented) that is produced before applying the N3 rules for Java translation :
_:sk_JPANEL_FIELD_34 a gengui:Panel. _:sk_JPANEL_FIELD_34 gengui:hasComponent _:sk_JTEXT_FIELD_36. _:sk_JPANEL_FIELD_34 gengui:hasComponent _:sk_JLABEL_DT_35. _:sk_JPANEL_FIELD_34 gengui:belongsToForm _:sk_JPANEL_FORM_23. _:sk_JLABEL_DT_35 a gengui:Label. _:sk_JLABEL_DT_35 <http://java.sun.com/method#setToolTipText> ("First name and last name"). _:sk_JLABEL_DT_35 java:text "name". _:sk_JTEXT_FIELD_36 a gengui:TextField.
The correspondance is indicated above with the color code: the panel becomes the subject of xf:textarea.
So, in plain english, I must for a panel having a gengui:TextField such as _:sk_JTEXT_FIELD_36, add a triple with the xf:textarea predicate:
{ ?PANEL gengui:hasComponent ?TEXT_FIELD. ?TEXT_FIELD a gengui:TextField. ?PANEL gengui:hasComponent ?LABEL_COMPONENT. ?LABEL_COMPONENT java:text ?LABEL. }=>{ ?PANEL xf:textarea ?TA. ?TA xf:ref "???". ?TA xf:label ?LABEL. }.
Of course the big trouble is the xf:ref , bacause the XML data model of XForms is not RDF.

These lines in deductions/n3_new/generic_gui_projection-rules.n3 are a problem, because they are much too Java-oriented:
javapr:GUIKBAdapter javam:add (?JPANEL_FIELD ?JLABEL_DT 0). javapr:GUIKBAdapter javam:add (?JPANEL_FIELD ?JTEXT_FIELD 1).
So I added in the same rule 2 triples for a new predicate gengui:hasComponent :

DONE add .ttl suffix recognition
Revision 894
- import URL with .xml suffix: recognize RDF and plain XML files
needed to adapt Gloze to process input URL's instead of Files : created GlozeURL as a replacement of Gloze
tested with http://www.agencexml.com/xsltforms/address.xml
Will mail to Steve Battle of Gloze, and also tell him that :
Although it's not implied by your License, it's a pleasure to share my modifications.
First I needed to adapt Gloze to process input URL's instead of Files, so I created GlozeURL as a replacement of Gloze :
http://eulergui.svn.sourceforge.net/viewvc/eulergui/trunk/eulergui/src/main/java/com/hp/gloze/GlozeURL.java?view=markup&pathrev=894
The modifications are rather systematic, replacing File by URL in the right places. So it should be really a replacement of original Gloze, and work whenever original Gloze works.
I made class GlozeURL extend Gloze, to avoid compilation errors and propagation of modifications elsewhere. But if you agree to use GlozeURL as the new Gloze, you should just remove the inheritance and rename GlozeURL to Gloze, and it should be OK. While I was here, I added generic arguments in a few places to avoid yellow markers in eclipse, and added curly braces for if blocks, that most code checkers object to.
Second, I've made a "short" list of important XML Schema that are automatically added to Gloze argument, depending on XML namespaces present in input file.
The "short" list of important XML Schema is here in class XMLExport :
http://eulergui.svn.sourceforge.net/viewvc/eulergui/trunk/eulergui/src/main/java/eulergui/export/XMLExport.java
The automatic addition to Gloze argument, depending on XML namespaces present in input file, occurs here in class N3SourceFromXML_Gloze :
http://eulergui.svn.sourceforge.net/viewvc/eulergui/trunk/eulergui/src/main/java/eulergui/inputs/N3SourceFromXML_Gloze.java
There is a small SAX ContentHandler that just records the XML namespaces present in input file.
There still problems:

TODO : watch Henry Story: http://blogs.sun.com/bblfish/entry/froscon_the_free_and_open
I need to expose the N3 prefixes to the XMLExport class. Indeed Gloze iterates on the given XML Schema for the RDF to plain XML translation, so it's not possible to add all the known XML Schema to the context. A partial list of of the most famous and useful XML Schema: XSD itself, XHTML, XForms, XSLT, SVG.
I sent this message on EulerGUI to the java-source.net team .
After more reflection, EulerGUI (http://eulergui.sourceforge.net/) is a hybrid creature.
I suggested it in the category "rules engines" because it wraps Drools as a rules engine for the N3 logic language (http://www.w3.org/DesignIssues/N3Logic), and because it integrates 4 rule engines.
But EulerGUI is also an IDE, not for Java, but for the Semantic Web.
So it could well be in categories IDE, and RDF.
EulerGUI also has importers for models and data in UML, eCore, plain XML, XML Schema. So it could well be in category UML.
Kind regards
Almost ready for EulerGUI 1.4 . I'd like to add XML export using Gloze .
Xorion will be an open source, XML-database based content/community management system that makes extensive use of XQuery and related technologies. The goal is to create a Drupal-like community project that can be used with a RESTful Services architecture to host rich XML documents as well as blogs and other components.

Since I had problems with public servers, I wanted to try a local one.
I did this :
cvs -z3 -d:pserver:anonymous@joseki.cvs.sourceforge.net:/cvsroot/joseki co Joseki3
ant build
Then I started the server like this:
http://www.joseki.org/start.html
Then the server was here:
Alas! With a simple query pasted from using SPARQL to explore an unknown dataset :

I got :

So I started the Joseki distribution. It works !
I have to see how to add documents in the database, and also try TDB (TDB is a component of Jena. It provides for large scale storage and query of RDF datasets using a pure Java engine. TDB supports SPARQL.).
The feature is implemented and documented, but I still have to find some SPARQL public endpoint with responses for CONSTRUCT queries.

query from SPARQL services (using ARQ): reloading project file is OK
TODO : change the test to have a non-empty query result - WIP
To start with nothing but a SPARQL endpoint and to dive in and learn about the data, the basic mechanism by which we can do this is by writing queries that use variables to find all of the predicates and all of the types that exist in a dataset, and then to pick out interesting predicates and types and use open-ended queries to explore the structure of the data. Dean Allemang has written a blog post on this exact subject, so I'll gladly reference his writing on using SPARQL to explore an unknown dataset.

Added Thorsten's repository for Pellet in EulerGUI.

Using Leigh Dodds' tutorial: introducing-sparql-querying-semantic-web-tutorial page 3
See SPARQL Query Language for RDF ( W3C Recommendation 15 January 2008 )
./pellet.sh query -q ~/ontologies/examples/pe.sparql ~/ontologies/PeriodicTable.owl
where pe.sparql contains:
PREFIX table: <http://www.daml.org/2003/01/periodictable/PeriodicTable#> SELECT ?name WHERE { ?element table:name ?name. }
the answer is :
"erbium"^^http://www.w3.org/2001/XMLSchema#string "strontium"^^http://www.w3.org/2001/XMLSchema#string etc ...
Its also possible to replace the SELECT with:
CONSTRUCT { ?element table:name ?name. }
but then the result will be in RDF XML (no N3 output possible).
See also for Protégé 3 : http://protege.stanford.edu/doc/sparql/
It was:

After suggestions by Paul:
A lightweight IDE for Artificial Intelligence. Started as GUI for the Euler reasoning engine. The sources can be N3, RDF, OWL, UM, eCore, plain XML or XSD, files or URL's. Wraps Drools (or CWM, FuXi) as N3 rules engines. Model based app. generation.
Now both ReDeFer and Gloze are integrated in EulerGUI (in Subversion), so
it's more simple to compare. The output is quite similar in both. I corrected
<xsd:all>
in ReDeFer. I did nothing in Gloze, except a bit
of defensive programming in two Jena classes. The problems I'm aware of are:
xforms_:appearanceType a owl:Class ; owl:unionOf ([ a owl:DataRange ; owl:oneOf ( "full"^^xsd:string "compact"^^xsd:string "minimal"^^xsd:string ) ]) .
when it should be:
xforms_:appearanceType a owl:Class ; owl:equivalentClass [ a owl:Class ; owl:oneOf ( xforms_:OWLIndividual_full xforms_:OWLIndividual_compact xforms_:OWLIndividual_minimal ) ] . xforms_:OWLIndividual_full a owl:Thing ; rdfs:label "full" . xforms_:OWLIndividual_compact a owl:Thing ; rdfs:label "compact" . xforms_:OWLIndividual_minimal a owl:Thing ; rdfs:label "minimal" .
From "missing features":
- open a form "Déductions style" for an N3 file in project;
this one is a nice feature that rises architectural questions:
This is quite easy to create a EulerGUI Project, add to it the current N3 source, and the swing-rules2.n3p project, then run that project (need to set the edited File to the current N3 source). The point needing more reflexion is "guess where are the RDFS or OWL sources that define used properties and prefixes".
Not in "missing features"
Using Gloze, this feature is quite easy to add.
From "missing features": that was not writen, only this was listed:
button to export the whole project:
- as a zip file, that is, the .n3p file plus all local files refered
- as a Drools project (what is a Drools project ?)
- as Protégé OWL project

Hi Roberto
I now fully integrated XML and XSD mapping in EulerGUI, see :
http://eulergui.svn.sourceforge.net/viewvc/eulergui/?view=log
Now I can work comfortably for the transforms themselves.
The OWL API used in Protégé and in other validators does not show all
accurately all problems.
An OWL RDF document has to be correct RDF, and to check that, the W3C
RDF Validator is convenient (based on the ARP Jena API:
http://www.w3.org/RDF/Validator/
About the test cases, I'll work on the Gloze samples, while also
comparing results between Gloze and ReDeFer.
Others XSD will include Maven (http://maven.apache.org/POM/4.0.0) and
XForms (http://www.w3.org/MarkUp/Forms/2007/XForms-11-Schema.xsd).
I'd like to have JUnit tests.
For conformance tests about the generated OWL, we can use the Jena
API, and the OWL API.
For testing the result themselves and non-regression, I propose to use
the test infrastructure of EulerGUI. It has the capability to query
any RDF.

Through Pierre Attar, I heard of CIM Tools:
add Maven config. in ReDeFer (not tested; for Maven build to work, it will need some directory changes in sources)
This happens the second time the application is started, as if Jena was not aware of the real database being opened .
The stack trace:

I found this in the Jena source, which looks suspect:
package com.hp.hpl.jena.db.impl; public class Driver_HSQLDB extends Driver_HSQL { public Driver_HSQLDB() { super() ; DATABASE_TYPE = "HSQL"; } }
Haha !!!!!!!! the latest version has:
DATABASE_TYPE = "HSQLDB";
Alas there is nothing more recent than Jena 2.6.0 in the repo:
http://jena.hpl.hp.com/repo/com/hp/hpl/jena/jena/
This means that I'm forced to debug Jena just because the newest stuff is not in Maven!
Now I'm commiter to ReDeFer on Google Code !
XML2RDF is not based on a XSLT. It is implemented using Java and the Jena library. The code is available from
http://code.google.com/p/redefer
I tested this small XHTML with XForms inside: http://www.agencexml.com/xsltforms/textarea.xml
The result from the web converter at http://rhizomik.net/redefer/#XML2RDF is globally satisfying, but I saw something questionable.
For this fragment:
<body>
<xf:textarea ref="sample:MyTextValue">
<xf:label>Note:</xf:label>
</xf:textarea>
the converted fragment is:
<rdf:RDF
xmlns:j.0="http://www.w3.org/2002/xforms#"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"

According the XML namespaces Rec., the attribute ref in the input XML is in no namespace (not in default namespace in scope !). I propose to translate it with an RDF prefix correcponding to the original base URI.
Looking at the specification
http://www.w3.org/TR/REC-xml-names/#scoping-defaulting
I read
The namespace name for an unprefixed attribute name always has no value.

Thanks for having a look. After some debugging, I saw that too.
I hope that this , and other stuff not conforming to the OWL 2
structural model, will be cought with appropriate error messages.
Maybe doing XML Schema validation ; I saw this Schema for OWL XML :
http://www.w3.org/2007/OWL/wiki/OWL_XML_Schema
but I don't know whether there is one for RDF XML serialization of OWL.
In the Protégé OWL 2 tutorial I saw the way to create Enumerated Classes in Protégé 4 (see parag. 7.3 Enumerated Classes).
Then I know how it should look like in RDF XML serialization for OWL:
<owl:Class rdf:about="http://www.w3.org/2002/xforms#appearanceType">
<owl:equivalentClass>
<owl:Class>
<owl:oneOf rdf:parseType="Collection">
<rdf:Description rdf:about="#minimal"/>
<rdf:Description rdf:about="#compact"/>
<rdf:Description rdf:about="#full"/>
</owl:oneOf>
</owl:Class>
</owl:equivalentClass>
</owl:Class>
instead of :
> <owl:Class rdf:about="http://www.w3.org/2002/xforms#appearanceType">
> <owl:unionOf rdf:parseType="Collection">
> <owl:DataRange>
> <owl:oneOf rdf:parseType="Resource">

What it is
Triplr (verb): a service that generates RDF Triples from URIs.
The content at the original URIs must be readable as one of the syntaxes Raptor knows - RDF ones, RSS, Atom, Microformats that have a GRDDL profile and so on. The full list is given in How... can I use it?
For instanciating a Method call with a list as object, a resource was wrongly taken in account as a literal string.
Before doing a new release of EulerGUI, I put the Déductions GUI rules in a new directory:
cp -r n3 n3_new cd n3_new sed -e 's/class="n3_project/class="eulergui.project/' -i *.n3p
I need also to change the eclipse launch configurations in workspace :
cd .metadata/.plugins/org.eclipse.debug.core/.launches sed -e 's=/deductions/n3/=/deductions/n3_new/=' -i *.launch
Alas this broke all the XML .n3p files.
A triple involving a Java object in first position (subject) will be interpreted as a JavaBean property, e.g. :
:myWindow any_prefix:visible xsd:true .
will be interpreted as :
myWindow.setVisible(true);
Precedently only predicates with the Java prefix were interpreted as Java properties.
Also method calls are now detected, no matter what the N3 prefix is, as long as it ends with # :
:myWindow any_prefix:setState ( 1 ) .
This paves the way for Déductions GUI rules: migration to generic platform.
After the correction from Roberto, it works fine :
saxonb-xslt XForms-11-Schema.xsd xsd2owl.xsl > XForms-11-Schema.redefer.owl
And I can load it readily Protégé 4 ! :))))))))
I saw this; in fact it passes through UML (two dialects!):
From OWL to Plone : I found a working path to transform an OWL ontology into a working Plone content-type. Here is my recipe
http://www.akasig.org/2005/04/28/from-owl-to-plone/
I created a new variant of the basic Person test, person_import2.n3p
,
that imports a new variant of the basic Déductions GUI rules,
swing-rules3.n3p.
For now only the classes are modified, not the java-specific predicates. The generic GUI platform objects are tagged as Java objects according to the chosen platform, e.g. :
{ ?W a gengui:TextField. javapr:thisApplication app:platform app:Java . } => { ?W a java:javax_swing_JTextField } .
This amounts to insert one more inference step.
OWL API is available through Maven: http://owlapi.sourceforge.net/source.html
Tonight I realized the big potential of having a 2 directional plain XML <--> RDF correspondance. On input, a plain XML can be added to the RDF store. For instance, it can come from an XForms form. On output, it can solve the problem of generating plain XML out of an RDF object graph. And this last feature is needed for many use cases, as plain XML is ubiquitous today (feed an instance for an XForms, XBRL report). XBRL in Cover pages .
Gloze is maintained ! Got a mail from Steve after 1 day.
There is also : Krextor – An Extensible XML→RDF Extraction Framework, by Christoph Lange, but it is not generic like Gloze, it is a framework where one has to wrtie XSLT for each XML vocabulary. I just noticed Christoph Lange's answer to my post on Protégé list :
https://mailman.stanford.edu/pipermail/protege-owl/2009-August/011907.html
I read Gleaning Resource Descriptions from Dialects of Languages (GRDDL). W3C is now completely at a stage where new specifications are meant to connect newer concepts (RDF here) to older (plain XML).

One more project, XSLT based, to convert from XML and XSD to RDF and OWL :
Sent a mail to Roberto:
The resources provided on the Rhizomic are all interesting to me in
the perspective of developing business application with RDF
techniques.
I tried the XSD to OWL transform from your site, with this large XSD,
namely latest XForms XML Schema :
http://www.w3.org/MarkUp/Forms/2007/XForms-11-Schema.xsd
The result has an error at line 79 :
<owl:onProperty rdf:resource="#&xforms;instance"/>
as you can see e.g. in Protégé 4.
It should be :
<owl:onProperty rdf:resource="&xforms;instance"/>
or
<owl:onProperty rdf:resource="#instance"/>
I wanted to try locally, but the xsl file provided on your site is not
sufficient, because the imported XSLT xsd2owl-functions.xsl cannot be
found on your site.

Sonar enables you to collect, analyze and report metrics on source code. Sonar not only offers consolidated reporting on and across projects throughout time, but it becomes the central place to manage code quality.
I followed http://docs.codehaus.org/display/SONAR/The+2+minutes+tutorial, but I didn't like the idea of deleting something in my local Maven repo, so I did:
mvn clean install org.codehaus.mojo:sonar-maven-plugin:sonar

Thread : EulerGUI 1.2.1 + Déductions application generator
Déductions is a Java Swing application generator from OWL models and N3 logic rules.
The User Manual, for the application designer.
This is a framework (Open Source, compatible but not Protégé-based) allowing to mix ontologies and a RETE forward chaining engine (Drools). This a quite similar to the SWRL plugin of eclipse, except that the rule language is N3 logic . N3 logic is similar to SWRL in its semantics, but the syntax is similar to the body of SPARQL queries. N3 is a good candidate for a universal data + models + rules + queries textual language. The RDF subset of N3 is perfectly isomorphic to RDF, but as human readable as can be. And it is readable by Protégé, Jena, and others tools. OWL, being expressed as RDF, is thus also expressible in N3. Here is an example:
:Person a owl:Class . :name a owl:DatatypeProperty ; rdfs:domain :Person ; rdfs:range xsd:string ; rdfs:comment "First name and last name" ; rdfs:label "name" . :Address a owl:Class . :hasAddress a owl:ObjectProperty ; rdfs:domain :Person ; rdfs:range :Address ; rdfs:comment "click to enter address"@en ; rdfs:label "address" .
For a developper, and even some domains experts, it can be quicker to enter initial models and facts in N3 with an editor having syntax coloring. Then Protégé can be used to visualize, navigate, update, and Description Logics reasonning.
EulerGUI is a lightweight IDE for developping and testing projects composed of N3, OWL, RDF(S) and UML ontologies and databases, and rules in N3 logic.
The sources can be N3 (Notation 3), RDF, OWL, UML or eCore, files or URL's.
The rules are in N3 logic; so the same rule language is used for infrastructure (form generation) and for business rules. There are four N3 rules engines: in Prolog, Python (Fuxi, CWM) , Java (Drools - RETE) .
In 2 clicks EullerGUI allows to generate and run Java Swing GUI's from OWL models and rules from the Deductions project.

* The Deductions vision .
[Announce] EulerGUI 1.2.1 + Déductions application generator
http://www.nabble.com/drools---user-f11823.html
The preceding announce on this list was on february 23:
In short, EulerGUI is an IDE centered around a Semantic Web language called N3. N3 is a good candidate for a universal data + models + rules + queries textual language. The RDF subset of N3 is perfectly isomorphic to RDF, but as human readable as can be. And it is readable by Protégé, Jena, and others tools. OWL, being expressed as RDF, is thus also expressible in N3. Here is an example for an OWL model :
:Person a owl:Class . :name a owl:DatatypeProperty ; rdfs:domain :Person ; rdfs:range xsd:string ; rdfs:comment "First name and last name" ; rdfs:label "name" . :Address a owl:Class . :hasAddress a owl:ObjectProperty ; rdfs:domain :Person ; rdfs:range :Address ; rdfs:comment "click to enter address"@en ; rdfs:label "address" .
Here is an example of a simple rule in N3 logic :
{ ?C hasParent ?P. ?P hasBrother ?B } => { ?C hasUncle ?B }.
This rule is translated into Drools, giving this:
rule "family-rules.n3 0" when Triple( $C : subject, predicate == "<file:/home/jmv/family-rules.n3#hasParent>", $P : object ) Triple( subject == $P, predicate == "<file:/home/jmv/family-rules.n3#hasBrother>", $B : object ) not( Triple( subject == $C, predicate == "<file:/home/jmv/family-rules.n3#hasUncle>", object == $B ) ) then Triple newTriple; newTriple = new Triple( $C, "<file:/home/jmv/family-rules.n3#hasUncle>", $B ); insert( newTriple ); endncle>", $B ); insert( newTriple ); end
As you can see, a negation of the consequent (RHS) is added in the antecedent, to avoid extra responses.
This is one of the new features. The others are :
The rule base, the models, and the data are exportable for using with Drools independently. So, for the Drools community, EulerGUI allows to import models and data from N3, RDF, OWL, UML, eCore documents. Also for some people, writing N3 rules can be easier than Drools language.
As you see above, the translation makes use of a particuliar form of Drools language, which makes use of a single Java class, Triple, that models RDF statements. This is quite far from the intended Drools usage, but it shows the power and flexibility of Drools. When embedded into generated Java Swing applications, a Drools engine is able to generate a form in a few milliseconds from the class model! Also this design, based on a single Java class, allows to add and remove business classes at runtime.
Déductions is a Java Swing application generator from OWL models and N3 logic rules.

After correcting a slow algorithm and adding N3 escape """ to strings if necessary, I was able to use EulerGUI to convert the UML 2 metamodel into OWL. This is just a by-product of being able to express eclipse eCore models in N3. The funny thing is that the UML-OMG guys want to translate the Semantic Web things into their stuff (see OMD), and the Semantic Web guys (like me) do the converse.
To go from XMI to OWL the data flow (completely implemented by EulerGUI) is:
XMI --> N3 representation of the XMI --> conversion through N3 rules --> OWL N3 representation
The N3 rules used for conversion are here :
http://deductions.svn.sourceforge.net/viewvc/deductions/n3/ecore_owl-rules.n3
A typical rule is the following:
{
?ECORE_CLASS a ecore:EClass .
} => {
?OWL_CLASS a owl:Class .
?OWL_CLASS :translatedFromECORE ?ECORE_CLASS .
} .
This simple eCore to OWL translation processes: Class, eSuperTypes, name, eStructuralFeatures. These eCore features are left aside for now: lowerBound, upperBound, eOpposite, containment="true", derived="true".
The resulting OWL converted from the UML 2.2 metamodel allows one to navigate into this big metamodel in Protégé, to write rules relying on UML metaclasses and predicates, and to enter instances (actual UML user models) in Protégé.
To make a complete translation, one should also translate the OCL constraints and operations, that could be converted into SWRL or N3 logic. This is quite a bit a work, but the OCL parser from eclipse is usable.
There might still be some imperfections from the point of view of UML or OWL experts.
I put the N3 file for the OWL conversion of the UML 2.2 metamodel (suitable for Protégé) here:
http://deductions.sourceforge.net/models/UML2-OWL_model.n3
The HTML generated in Protégé with OWLDoc is here:
http://deductions.sourceforge.net/models/UML2-OWL_model_doc/
On the web the UML2 metamodel in the eclipse eCore XMI dialect, that was used for the conversion, is here :
I found where the settings are on kubuntu: in konqueror, open settings:.
See http://www.kubuntu.org/docs/kquickguide/C/ch04s04.html
Instead of monitoring several forums and threads , it is simpler to monitor Jos De Roo's profile:
https://sourceforge.net/users/josd
To be very concrete here is the translation I propose for :
public class Item {
public String name; // or getName + setName
public int unitPrice;
public int computePrice( int quantity ) {return unitPrice*quantity;}
}
----------- OWL/N3 translation ------------------
@prefix owl: <http://www.w3.org/2002/07/owl#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix um2: <http://schema.omg.org/spec/XMI/2.1/>.
:Item a owl:Class.
:name a owl:datatypeProperty;
rdfs:label "name";
rdfs:domain :Item;
rdfs:range xsd:string.
:unitPrice a owl:datatypeProperty;
rdfs:label "unitPrice";
rdfs:domain :Item;
rdfs:range xsd:positiveInteger.
:Item uml2:ownedOperation :computePrice.
:computePrice rdfs:label "computePrice";
uml2:ownedParameter :quantity.
:quantity uml2:type xsd:positiveInteger;
rdfs:label "quantity". :computePrice uml2:ownedParameter :returnComputePrice. :returnComputePrice uml2:type xsd:positiveInteger; uml2:direction "return".
Above I follow paragraph "7.2 Abstract Syntax" in "OMG Unified Modeling Language (OMG UML),
Superstructure, V2.1.2", except that I use XSD datatypes and rdfs:label as usual in OWL.
First I took the eCore version of the UML 2 metamodel from my eclipse 3.5 installation:

Because the pom.xml was not in a good state, I had to run release:prepare this way :
mvn release:prepare -Dresume=false
The release.properties file, generated by the release:prepare stage, was:
#release configuration #Tue Aug 25 13:02:14 CEST 2009 scm.tag=eulergui-1.2 project.scm.eulergui\:eulergui.developerConnection=scm\:svn\:https\://eulergui.svn.sourceforge.net/svnroot/eulergui/tags/eulergui-1.2 project.scm.eulergui\:eulergui.connection=scm\:svn\:https\://eulergui.svn.sourceforge.net/svnroot/eulergui/tags/eulergui-1.2 scm.url=scm\:svn\:https\://eulergui.svn.sourceforge.net/svnroot/eulergui/tags/eulergui-1.2 preparationGoals=clean verify project.dev.eulergui\:eulergui=1.3-SNAPSHOT scm.commentPrefix=[maven-release-plugin] scm.tagBase=https\://eulergui.svn.sourceforge.net/svnroot/eulergui/tags project.scm.eulergui\:eulergui.tag=HEAD completedPhase=end-release project.rel.eulergui\:eulergui=1.2 project.scm.eulergui\:eulergui.url=https\://eulergui.svn.sourceforge.net/svnroot/eulergui/tags/eulergui-1.2
During the release:prepare stage, Maven manipulates these tags in pom.xml :
<version>1.3-SNAPSHOT</version> ... <scm> <developerConnection>scm:svn:https://eulergui.svn.sourceforge.net/svnroot/eulergui/tags/eulergui-1.2</developerConnection> <connection>scm:svn:https://eulergui.svn.sourceforge.net/svnroot/eulergui/tags/eulergui-1.2</connection> <url>https://eulergui.svn.sourceforge.net/svnroot/eulergui/tags/eulergui-1.2</url> </scm>
and commits the copy of the sources in the tags/ directory in the Subversion repository.
The release:perform stage just uploads the files on the EulerGUI Maven depot on sf.net .
Then I created the Web site generated by Maven :
mvn site
mvn site:deploy
but the unzipping didn't work :
Transfer finished. 43792 bytes copied in 1.831 seconds Executing command: cd /home/groups/e/eu/eulergui/htdocs/maven-site/.; unzip -q -o wagon812543537683092844.zip; rm -f wagon812543537683092844.zip Executing command: chmod -Rf g+w,a+rX /home/groups/e/eu/eulergui/htdocs/maven-site sftp://web.sourceforge.net/home/groups/e/eu/eulergui/htdocs/maven-site - Session: Disconnecting sftp://web.sourceforge.net/home/groups/e/eu/eulergui/htdocs/maven-site - Session: Disconnected
It fails when a shell is not active through :
ssh -t jmvanel,eulergui@shell.sourceforge.net create
One can do the unzipping through the shell on Sourceforge. But it is clean to do it with:
mvn site:deploy
The error above was due to a bad <url> in pom.xml :
<distributionManagement>

I had to set a mailman password. For that I had to go to "admin/features".
Put in EulerGUI project in n3_rules_good_practices.html .
Motivation
Suppose the original rule OR is writen as :
{ T1 ... Tn . Tn+1 ... Tp } => { Consequent } .
You want to reuse that rule with the rest of antecedent Tn+1 ...
Tp
and the consequent unchanged, but with a different begining of
antecedent.
You are tempted to copy and paste the original rule, and change the begining of antecedent.
Mechanics
Instead of that bad copy and paste, here is the refactoring:
T1 ... Tn
with new
predicates, using the same variables, resulting in T'1 ... T'm
;
then OR becomes OR' :
{ T'1 ... T'm . Tn+1 ... Tp } => { Consequent } .
and it is this form that can be reused;
{ T1 ... Tn } => { T'1 ... T'm } .
In situations where the original rule OR would trigger, OR" then OR' will trigger.
Example
The original begining of antecedent is in blue, and the rewriting with new predicates is in green.
Original rule in app_gui-rules2.n3 :
{
?CLASS gui:hasForm ?FORM .
?CLASS log:notEqualTo owl:Thing . ?PROP a :OWLProperty . ?PROP rdfs:domain ?CLASS . # only if there is no field for that property: (?SCOPE 1) e:findall ( ?FIELD_ { ?FIELD_ gui:inputWidgetSpecification ?PROP . } () ) . } => { ?FORM gui:hasField ?FIELD . ?FIELD gui:inputWidgetSpecification ?PROP . _:d eg:trace ( "add an EMPTY field in the form: " ?PROP ?FIELD ) . } .
Extraction of the rest of antecedent as a second intermediary rule (note that the consequent is copied verbatim ) :
{ # add Fields To Form From Class (direct properties, no properties of subclass)
?FORM gui:addFieldsToFormFromClass ?CLASS . ?PROP a :OWLProperty . ?PROP rdfs:domain ?CLASS . # only if there is no field for that property: (?SCOPE 1) e:findall ( ?FIELD_ { ?FIELD_ gui:inputWidgetSpecification ?PROP . } () ) . } => { ?FORM gui:hasField ?FIELD . ?FIELD gui:inputWidgetSpecification ?PROP . _:d eg:trace ( ">>> addFieldsToFormFromClass: add an EMPTY field in the form: " ?PROP ?FIELD ) . } .
Extraction of the begining of antecedent as a first intermediary rule :
{
?CLASS gui:hasForm ?FORM .
?CLASS log:notEqualTo owl:Thing . } => { ?FORM gui:addFieldsToFormFromClass ?CLASS . } .
Use case : When the user clicks to choose among subclasses, the fields for chosen subclass are added at once, without fields for its superclass of course.

N3 syntax error with EYE in rule about rules (New)

Hi
This time it is an undoubtful error. I created a simple rule to infer RDFS properties from rules :
{
?A => ?C .
?A log:includes { ?SA ?PA ?OA } .
?C log:includes { ?SC ?PC ?OC } .
} => {
?PA a rdfs:Property .
?PC a rdfs:Property .
} .

Applying rules to form generation from OWL models
The reference specification: http://xmlns.com/foaf/spec/index.rdf
http://xmlns.com/foaf/spec/#term_mbox
I came across this, that Déduction form gen. does not process well :
foaf:mbox
a owl:InverseFunctionalProperty , owl:ObjectProperty ;
rdfs:comment "A personal mailbox, ie. an Internet mailbox associated with exactly one owner, the first owner of this mailbox. This is a 'static inverse functional property', in that there is (across time and change) at most one individual that ever has any particular value for foaf:mbox."^^xsd:string ;
rdfs:domain foaf:Agent ;
rdfs:isDefinedBy "http://xmlns.com/foaf/0.1/"^^xsd:anyURI ;
rdfs:label "personal mailbox"^^xsd:string ;
rdfs:range owl:Thing .
The explanation is simply that "personal mailbox" is an RDF resource, and not a string, e.g. :
<foaf:mbox rdf:resource="mailto:wkearney99@hotmail.com" />
What is lacking in the FOAF specification is the information that this RDF
resource is a mailto:
URL (to be able to assist user input). So we
should somehow enforce in the GUI the constraint that a the URL begins with
mailto:
.
The other interesting thing is that mbox is an Inverse Functional Property. The consequence for the GUI is that, given the Agent being the domain of the property, and in the absence of an existing mbox, the mbox is necessarily a new RDF resource.

One must be able to generate readable diagrams, and that in itself is a big challenge. There is GraphViz occupying this territory; but what it does without specific instructions it is not beautiful.
GraphViz is already added to EulerGUI. But I do not give specific instructions, just the nodes and links
For half a dozen nodes and links, things are going well ... But beyond :-( .
This is a nice use case for rule based processing; for a long time I have been running around this problem. My boss at MW was also interested in that. Now I am better prepared because I got like a training with the generation of forms.
Until today I had not thought of generating instructions for GraphViz. The least I can do is :
Also it is very important to connect specific diagram rules with pre-canned queries like:

Anyway this a major improvement; it will make thingd easzier for Déductions new architecture.
Had a very quick look at CALO, a US defense project, that aims at a:
Cognitive Assistant that Learns and Organizes
Although neither application (under Windows only) nor source is available, some ideas could be extracted.
Anyway, quite similar to my "good servant" concept.
In fact, there is an Open source project : SPARK (the SRI Procedural Agent Realization Kit )
They have lots of tools:
http://www.tonesproject.org/index.php?option=com_wrapper&Itemid=84
For me, the most interesting seems:
The Ontology Modularization tool implemented an algorithm for extracting modules from OWL ontologies.
They also have an ontology repository (integrated in Protégé 4):
http://owl.cs.manchester.ac.uk/repository/browser
http://www.w3.org/2007/OWL/wiki/New_Features_and_Rationale
For OWL 1, here is a clean implementation by Jos de Roo in the Euler project :
http://eulersharp.svn.sf.net/viewvc/eulersharp/trunk/2003/03swap/eye-owl2.html
Each OWL feature is implemented in a separated file, generally with a single N3 implication. This allows to add to the rule base just the needed features. This makes for cleaner and more efficient rule bases.
In Déduction form generation I should remove rpo.n3 and use these N3 rules.
I attack to something I left out for months:
Duplicated triples with Drools engine
and it's annoying to write the output on the fly ...
To add a condition in the generated Drools code, I must have treated all the triples in the consequence, and is not convenient with my event based API.
Basically I must assert the consequence only if that if it is not already true.
It will be better, but not yet perfect.
Pave the way by slitting the output in 4 string buffers.

I just added this to the "Missing features" list in EulerGUI Manual:
- connect to Sesame database; this includes extracting the relevant triples from the database into the in-memory inference engines; both in EulerGUI and in the generated application.
But I realize that analysing a rule base to find a low volume extraction (from the most specific antecedents) from an RDF database is not an easy task.
A scenario both easy to implement, and that makes sense from a user point of view, is to add to the facts made available to the inference engine the result of a user SPARQL query from a SPARQL database. Here are the databases I selected:

To ease the porting of Protégé 3 plugins to Protégé 4, maybe also an ontology based approach could be appropriate.

I first tried the raw sentence:

There is a card X1.
The card X1 is a n:means of p:payment .
Ones sees that this is wrongly understood, as p: stands for proper noun. Adding
% ./ape.exe -solo paraphrase -guess -text "A card is a means of a payment ."
There is a card X1.
The card X1 is a n:means of a n:payment .
% ./ape.exe -solo paraphrase -guess -text "Every card is a means of a payment ."
If there is a card X1 then the card X1 is a n:means of a n:payment .
Alas for OWL translation, "Adjectives not supported", for example in:

It would not difficult to to write a rule set to populate the current class Project from a N3 document.: instantiate Project, instantiate the sources Map<String, N3Source>, add the URI to N3Source, etc.
A new file extension is needed, to avoid the confusion witth ordinary N3 sources. Or maybe just *.project.n3 .
Currently we have :
Model+App.Spec.--> Conceptual GUI--> Swing GUI --> instantiation
We want to migrate to:
Model+App.Spec. --> Conceptual GUI--> Detailed Abstract GUI--> Swing GUI --> instantiation
This may add an exessive CPU time. There should be a way to "compile" the rule base given that we are not interested in intermediary results, but just by final Java objects.
Anyway, what we will have is many correspondences like:
agui:Panel ---> java:JPanel
For one-to-one correspondences like this, there can be declarations like:
agui:Panel aj:correspondence java:JPanel .
plus a rule at instance level:
{ ?ABSTRACT_CLASS aj:correspondence ?JAVA_CLASS .
?ABSTRACT_INSTANCE a ?ABSTRACT_CLASS .
} => {
?JAVA_INSTANCE a ?JAVA_CLASS .
# keep track of the translation for further rules:
?ABSTRACT_INSTANCE aj:translation ?JAVA_INSTANCE .
} .
and similar rules at instance level for properties of the translated objects:
{ ?ABSTRACT_PROPERTY aj:property_correspondence ?JAVA_PROPERTY .Lots of rules for a one-to-one correspondence ! An alternative is to just reuse the existing objects, and simply annotate them as Java objects.
?ABSTRACT_INSTANCE ?ABSTRACT_PROPERTY ?VALUE .
?ABSTRACT_PROPERTY a owl:DatatypeProperty .
?ABSTRACT_INSTANCE aj:translation ?JAVA_INSTANCE .
} => {
?JAVA_INSTANCE ?JAVA_PROPERTY ?VALUE .
} .
{ ?ABSTRACT_PROPERTY aj:property_correspondence ?JAVA_PROPERTY .
?ABSTRACT_INSTANCE ?ABSTRACT_PROPERTY ?ABSTRACT_VALUE .
?ABSTRACT_PROPERTY a owl:ObjectProperty .
?ABSTRACT_INSTANCE aj:translation ?JAVA_INSTANCE .
?ABSTRACT_VALUE aj:translation ?JAVA_VALUE .
} => {
?JAVA_INSTANCE ?JAVA_PROPERTY ?JAVA_VALUE .
} .
A rule at instance level:
{ ?ABSTRACT_CLASS aj:correspondence ?JAVA_CLASS .
?ABSTRACT_INSTANCE a ?ABSTRACT_CLASS .
} => {
?ABSTRACT_INSTANCE a ?JAVA_CLASS .
} .
Similar rules at instance level for properties of the translated objects; they are also simpler:
{ ?ABSTRACT_PROPERTY aj:property_correspondence ?JAVA_PROPERTY .
?ABSTRACT_INSTANCE ?ABSTRACT_PROPERTY ?VALUE .
} => {
?ABSTRACT_INSTANCE ?JAVA_PROPERTY ?VALUE .
} .

RuleML Challenge
http://www.defeasible.org/ruleml2009/cfp.txt
Former LinkeIn header:
Jean-Marc extends the Deductions frameworks for GUI generation to inheritance and adding pointers to a selection of objects.
I think about doing a command-line User Interface (CL-UI) generator alongside the GUI generator. This will generalize the design, and make it easier to record user actions and explore intelligent behaviors.
After writing "Summary for AI researchers", and exchanging mails with David Holz, I'm ready to design the exchanges between GUI and KB . There are 2 issues:
Point 2 is not a problem, although there may be ways more elegant than others.
The Java Swing architecture hopefully allows to catch events in a generic way. I should ask to the Abbot list.Point 3 is more architectural and difficult for me.
I want the KB (Knowledge Base) to be dynamic and persistent, it's not only one inference pass and goodbye. It is necessary to infer a GUI, which is dynamic.
One question is "how to manage the correspondance between real GUI objects and their counterpart in the KB" ? But I'm not sure whether I really need to manage the correspondance. Should I need that, the current instantiation architecture involving JavaScript variables whose name is the N3 Id makes the bidirectional correspondance. However the instantiation architecture involving JavaScript has one inconvenient; the variables are here forever when not explicitely disallocated. This can entail memory consumption; but readjusting the starting number for creating Id's will overwrite some of them. The user data, on the other hand, lives only in the KB. I added 2 primitives in N3 to remove and update a triple. Currently I only use the inference engine to generate forms (at runtime), but the actions after user events to update the KB are done in Java, but now that I can create a form from specification in milliseconds, I'll do as much as I can in rules. Currently, for each user actions involving creation of new GUI items, I hack a fresh Working Memory with the permanent facts + the user data but no GUI items at all. The Java objects and field assignments are done in a single batch just after rules firing.?X :createFormFromResource ?RESOURCEwill trigger the whole form generation inference for the given resource (see form-rules.n3) . And if this statement is retracted, the whole object graph representing the form in the KB is also removed. Since it started from a given Resource Id, no other GUI objects will be removed. PENDING: It would be nice if the KB could work directly on the real GUI objects. It should be possible since, after all, the KB is also in Java. A possibility is make hybrid obects implementing Triple and subclassing the Swing classes.

Tried to install Morla RDF, but that doesn't compile on KUbuntu :( . Sent a mail to the list.
It would not be difficult at all to integrate ACE in EulerGUI :
APE is available under the LGPL license, and it can also be used through a REST webservice. For example, an OWL ontology that corresponds to the ACE text
``Every man is a human.''
is given by the URL

OWL definition in RDFS : http://www.w3.org/2002/07/owl
Having the OWL properties plus the RDFS properties in the same KB apparently is the reason for infinite loops.
It's too much trouble to filter out the unwanted stuff; it's really time for implementing the N3 processor pipes.
add rdfs_owl-rules.n3 for rdfs to owl conversion

By chance, is there a public repository for reusable Drools rulesets and models ?
By chance, is there a public repository for reusable eCore models ?
Published on news://comp.object
Is there a public repository for reusable Object Oriented odels ?
For years I couldn't find one.
I think one of the reasons for non-existence is lack of reusable exchange format.
XMI is pretty variable and poorly formalized.
UML is too complex, also unstable, and the strictly OO part (Class diagrams) is mixed with the rest of the huge 250 metaclasses metamodel.
eCore could be a good exchange format, but it's rather limited to the eclipse - Java world.
It seems that the best exchange format for business model is OWL - Web Ontology Language ( http://www.w3.org/2004/OWL/ ).
OWL has classes and properties . It has no methods and interfaces, but for that it is quite possible to reuse exactly the UML metamodel.
An advantage of OWL (and more generally Description Logics frameworks) is that a class defined by its properties (e.g. an UnemployedPerson is a Person that has no Job) provides a more natural way of modelizing a domain than classic OO, where you have to use delegation for the situation when a Person becomes UnemployedPerson.
And, contrary to classic OO models, there are sites for searching and hosting OWL and RDFS ontologies on the Web :
But maybe there are projects and sites I'm not aware for OO models ?

Working on the UML--OWL rules.
We have a projet ( http://eulergui.svn.sourceforge.net/viewvc/eulergui/trunk/eulergui/pom.xml ) using a parser generator , for which we have extra Java sources, not for building with the application.
We generate the eclipse configuration with Maven, but I found no way to specify these extra Java sources so that they appear in the eclipse configuration.

If you saw my code, you would see that I'm traversing the UML model just like it were a plain eCore model (and by the way, I'm as much critic as you regarding UML, I heard you in Paris this winter).
So, what I'm asking is : is there a way to instantiate plain eCore objects from an XMI, disregarding the actual package ?
From what you answered I'm afraid that the answer is no, and that my use case was never considered.
Maybe it's enough to redefine this method in org.eclipse.emf.ecore.xmi.impl.XMLHandler :
protected EFactory getFactoryForPrefix(String prefix)
Before being independent like now, I spent 2 years building an EMF-like framework with generator in Java, generating C++. And I did exactly that, an XMI parser that instantiates plain vanilla MOF classes. But I doubt if can use my work for an OSS project.

I'm working on UML integration in EulerGUI , by using the EMF eclipse infrastructure.
Much like for RDF, the UML (or any XMI) is translated on the fly into N3.
It works already quite well, with also rules to translate UML expressed in N3 into OWL (in eulergui/examples ) .
The only point is jar dependencies; I want to avoid adding UML2 jars, and also eclipse stuff on Maven central depot is bugged.
So I'm asking you if it bothers you if I temporarily add the modifications in EulerGUI SVN .
It will not disturb your runs, it's just that you will have one class not compiling.
You might also want to add manually the necessary jars :
(after installing the corresponding eclipse plugins).
To avoid having a large release, I'm thinking of using Java Web Start (JNLP) , plus the Maven JNLP plugin :
http://mojo.codehaus.org/webstart/webstart-maven-plugin/jnlp-mojos-overview.html
Hopefully this would allow to download the auxiliary jars on demand, when the user starts using the feature.
An alternative is to use OSGi; but would OSGi reuse the Maven configuration ?
Searching Maven and OSGi bring several plugins , including this one :

Eclipse's TPTP didn't want to start (Unable to connect to the Agent Controller - Connexion refused). So I installed NetBeans 6.5.1 . Good news is that NB imports easily eclipse projects (using same directory possibly), inclluding run configurations. Bad news is that NB imposes more structure to a project that eclipse:
Because of point 1 , I couldn't compile the tests, so I removed them from the project. This dependency enforcing feature can be a very good thing, but it should be possible to disactivate it, especially when importing eclipse projects.

Hi all
In addition to use Maven to manage dependencies and build my application (http://eulergui.sourceforge.net/), I would like to re-use the dependencies specified in the pom.xml to carry out a lazy loading of the jars in my application. That would make it possible to release my application with the most important dependencies in XXX-jar-with-dependencies.jar, and the application would download the dependences as needed, like Maven does.
I see at least 3 possibilities:
I think that I am not the only one to have this kind of needs.
I would like to avoid a big distribution with many jars, and a run.sh and a run.bat. Thus I would not like to develop myself this kind of infrastructure.
Michael Justin answered:
There is a Java(tm) Technology thingy called "Java Web Start".
http://en.wikipedia.org/wiki/Java_Web_Start
Thanks Michael; indeed it helps; I always thought that JNPL donwloaded a monolythic application, but that's not the case :
The JNLP file can list resources as "lazy", which informs the JNLPclient that the application does not need those resources to start,but can retrieve them later on when/if the application requests them.
JNPL also can manage update of the local cache.
And I found this project that looks good to generate JNPL settings from Maven :

I am organizing a workshop which may be of your interest

at this moment in time, you are very welcome to propse a case study
later on, three case studies will be selected and all international groups working on model transformation are then invited to solve those case studies
so basically you could propose a case study for which you think you can very well illustrate the strengths of your approach
moi: sounds good !
Pieter: obviously, you should propose a well-balanced case study for any approach but you can always have some extension points that allow you to show off particular features :)
if you do participate in this initiative, it becomes part of my daily work to review your work at some point
moi: I feel that the interesting thing in my approach is that I'm not restricted to a technological family , although It's currently based on Web Semantics and Java . I want to interoperate with UML, eclipse EMF etc, SQL , and others . Because, I'm not a standard researcher, I ' am practionner who wants to offer useful stuff for many projects, and who wants to develop a business .

Jean-Marc writes a presentation on EulerGUI and Deductions frameworks for GUI generation. 3 days ago -
Jean-Marc extends the Deductions frameworks for GUI generation to inheritance and adding pointers to a selection of objects.
The client visit yesterday was not successful, because I failed to show the benefits of rule - based programming , and the demo. was not convincing enough.
I want to propose them a partnership were I will develop features they need most, like outputting PHP, replacing XSLT producing SVG, or develop business rules ( they offer services for civil engineering management ). I think that the biggest challenge is to come with a way of augmenting the generated application with code in traditional languages so that :
The first idea that comes to mind is, following the "Intelligent Modularity" principle, is to modelize the (Java) interfaces for the "augmentation code". Thus point 1. is easily realized by eclipse, provided that java source for interfaces is generated. Point 2. can be realized by some checking coherence between the interfaces and the way they are called.
Who says interface also says "factory", so there can be a singleton factory à la Spring.
Another ingredient are extension points à la eclipse to add functionalities in well-defined places. For instance if one want to add action buttons in a context of a property, like the GRAPH and REMOVE buttons of EulerGUI, there will be an extension point for that . The generated interface for N3 property pref:MyProperty could be :
package pref;
interface MyPropertyExtension {
void run( MyType value );
boolean isSameThread();
}
Each button will implement this interface. The design environment will be responsible for generating on the fly such interfaces, plus the Java methods to navigate the object graph , probably following a JavaBeans pattern (to detail <<< ).
The runtime environment will take care of actually calling the extension classes.
The runtime environment will also accordingly generate the glue code to navigate the object graph . There must be also a way to update (CRUD) the Knowledge base, like there is today the ITripleStore interface.
These ideas are quite straightfoward. Is this the way to achieve a seamless integration on the OO and ontology paradigms ?
I need to implement this in Drools, described thus in log-rules.n3 :
e:findall a rdf:Property;
rdfs:comment """ builtin that (?SCOPE ?SPAN) e:findall (?SELECT ?WHERE ?ANSWER).
unifies ?ANSWER with a list that contains all the instantiations
of ?SELECT satisfying the ?WHERE clause in the ?SCOPE ?SPAN of all
asserted n3 formulae and their log:conclusion """;
rdfs:domain rdf:List;
rdfs:range rdf:List .
A typical use is (1) :
(?SCOPE 1) e:findall (
?SUBTYPE { ?SUBTYPE rdfs:subClassOf ?TYPE } ?SUBTYPES )
or this with an empty result imposed (2) , here to check non-existence of subclasses :
(?SCOPE 1) e:findall (
?SUBCLASS { ?SUBCLASS rdfs:subClassOf ?CLASS } () ) .
A Drools query is not suitable, since the result of findall must be reused at rules firing time.
Looking from the latest Drools doc., the construct
from collect
seems appropriate.
rule "findall" when
$SUBTYPES : ArrayList()
from collect( Triple( predicate == "rdfs:subClassOf",
object == $TYPE ) )
# $SUBTYPE is in subject position, so to use $SUBTYPES on RHS
# in ?TYPE gui:subClasses ?SUBTYPES we can do:
then
for( Triple triple : $SUBTYPES ) {
String SUBTYPES_item = triple.getSubject();
insert( new Triple( $TYPE, "gui:subClasses", SUBTYPES_item ) );
}
end
This seems to compile in Drools !!!
Notes:
eval( $SUBTYPES.isEmpty() )

Not in RDF
http://dig.csail.mit.edu/2007/Talks/0110-rules2-tbl/#%281%29
???????????? TODO
I am pleased to announce EulerGUI 1.0 , a development environment for Semantic Web technologies , written in Java , under LGPL licence .
It uses Drools as an engine for the N3 logic and rules
(http://www.w3.org/2000/10/swap/doc/Rules).
N3 is a language equivalent to Semantic Web's RDF language, but much easier to read and write by hand.
Moreover, N3 has, on top of RDF, an extension for rules, e.g. :
{ ?x parent ?y } => { ?y child ?x }.
N3 logic (http://www.w3.org/2000/10/swap/doc/Rules) .
Among many other vocabularies searchable on Swoogle search site (http://swoogle.umbc.edu/), there is OWL from W3C, (OWL Web Ontology Language) that allows to express in RDF, and thus in N3, rich models with classes, properties, inheritance and constraints.
So in summary, N3 is a user-friendly language allowing to express facts, class and properties, and rules.
So what does that bring for developers ?
One of the use cases :
- open any number of RDF / OWL / N3 documents
- test and debug the rules using 3 rule engines (Drools, Euler, CWM)
- export all that project as a set of Drools packages, plus the facts in XMLEncoder format
- export all project as for use with Yap Prolog engine
You can also use standard Semantic Web tools such as Protégé and Swoop to edit and visualize RDF and OWL files. EulerGUI is perfectly complementary to these tools:
- Protégé allows to classify and validate an OWL ontology via the classic algorithms of the Description Logic;
- EulerGUI makes it possible to develop a rule base in N3 logic, and to export it for a Drools runtime, or Prolog Yap

<jmv> I did svn mkdir tags/ , so that tags/ is at the same level as trunk/ .
<jmv> I don't if I should give the developerConnection and tagBase as local file: path or repository https: path .
<jmv> I don't know
<jmv> I got it !
<jmv> I understood the SVN message : "Local operations do not take a log message"
<jmv> So I tried specifying <developerConnection> and <tagBase> as https: URL's , not file: .
<jmv> And it worked !
<jmv> NOTE: several pages give bad examples of specifying <developerConnection> and <tagBase> as file: URL : e.g. http://maven.apache.org/guides/mini/guide-releasing.html
<jmv> Also the tags directory on the repository is not created automatically by mvn relase:prepare , and nothing in the doc. says it should be done manually before .

<jmv> I am probably one of the rare people trying to do it the Maven way before having done a single release tagging before .

<jmv> I wonder if it's good practice to use http://MY_PROJECT.sourceforge.net/ as Maven depot ...

<jmv> <descriptorRef>jar</descriptorRef>
<jmv> </descriptorRefs>
<jmv> Well, it seems that I already have a plain jar here, without asking for it : http://eulergui.sourceforge.net/maven2/eulergui/eulergui/1.0-SNAPSHOT/
<jmv> However, it didn't upload the new release as eulergui-1.0 ; I guess I have to review my deploy specifcation ...
<jmv> I have another complaint : after regenerating my pom.xml upon release:prepare , it left it like this, and I'm afraid it will trigger the same problem next time :
<jmv> <developerConnection>scm:svn:file://PCIVENTIVE/home/jmv/src/eulergui_test/eulergui/trunk</developerConnection>
<handyande> jmv: prepare updates the pom, commits, branches and then updates the pom again
<handyande> so it should reference trunk before and after
<handyande> but it will create the tag for release:perform to use
<jmv> handyande, That's fine , it's just that I had problems with initial pom.xml having <developerConnection>scm:svn:file: , and it worked with initial pom.xml having <developerConnection>scm:svn:https:

TODO : explain internal design
As I mailed to Edson Tirelli, I'd like to know whether loading rules and facts in any order is allowed (before firing rules) . Of course I'm about to change the way I call Drools, but before that I'd like to know the status of this feature, is it a bug or is it forbiden.
DONE
- Drools N3 engine: insert together ALL the facts AFTER adding ALL the rules
This SOLVES ALL CURRENT PROBLEMS with bad results (NRI 2 works !)
I extracted from a larger model 2 rules. The problem is that the results from rule "0" should include all the results from rule "1" .
I claim this because:
Triple( subject == "<http://java.sun.com/class#javax_swing_JPanel>",
predicate == "<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>",
object == "<http://java.sun.com/class#ConcreteClass>" )
rdf:type
and object is
java:javax_swing_JPanel
should entail insertion in Working
Memory of a corresponding TripleResultNow, the issue is that in some test cases, large enough, there are results from rule "1" that are NOT included in the results from rule "0" .
The offending Triple item is here :
$ grep sk_JPANEL_FIELD_20 /tmp/result-34579.n3
_:sk_JPANEL_FORM_18 <http://java.sun.com/method#add> _:sk_JPANEL_FIELD_20 . #R
_:sk_JPANEL_FIELD_20 <http://jmvanel.free.fr/ontology/java_projection.owl#TEST_OK_KKKKKKKKKKKKKKKKKK> <http://java.sun.com/class#javax_swing_JPanel> . #R
There should be a Triple with :
_:sk_JPANEL_FIELD_20 <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> .
I feel that the problem is related to the fact that criteria C1 and C2 are , in the particuliar case of the offending Triple item, the same object .
Note that I use AssertBehaviour.EQUALITY .
The above mentioned rules:
rule "query.n3 0"
when
Triple( $OBJECT : subject,
predicate == "<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>",
$CLASS : object ) # C1
Triple( subject == $CLASS,
predicate == "<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>",
object == "<http://java.sun.com/class#ConcreteClass>" ) # C2
Triple( subject == $OBJECT, $PROP : predicate, $VALUE : object ) # C3
then
Triple newTriple;
newTriple = new TripleResult( $OBJECT, $PROP, $VALUE ); insert( newTriple );
end
rule "query.n3 1"
when
Triple( $JPANEL : subject,
predicate == "<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>",
object == "<http://java.sun.com/class#javax_swing_JPanel>" ) # C4
then
Triple newTriple;
newTriple = new
TripleResult( $JPANEL,
"<http://jmvanel.free.fr/ontology/java_projection.owl#TEST_OK_KKKKKKKKKKKKKKKKK>",
"<http://java.sun.com/class#javax_swing_JPanel>" );
insert( newTriple );

I'd like to have time to read this Drools article "Sequential Rete".
Stateless Drools engine could be used embedded in end-user application.
I had to comment out the usage of findall, as it is not yet implemented in Drools translation ! And that was the main problem!
Now there are many such messages on NRI 2 (NRI with individuals removed), but the GUI looks good anyway :
java.lang.IllegalArgumentException: adding container's parent to itself
Even though recursive expansion is activated:
app:globalSettings app:expandForms true .
However NRI complete doesn't show anything, with lots of messages :
GUIHelper.addTitledBorder( sk_JPANEL_FORM_225_11_, "traitement>" ) ;
// javax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: ReferenceError: "sk_JPANEL_FORM_225_11_" n'est pas défini
And on Purchase Order ( see Déductions - GUI generation : implement Property details ) there are no label before fields (regression ).

Some advices from the IRC :)
But the Drools user mailing list doesn't seem to work well ...
<jmv_> Hi all ; I sent a mail on the user list "debugging generated Drools source code", if you want to chat here, I'm available ...
<krisv> jmv_: https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-expert/html_single/index.html look at section 3.6.4 and 3.10 to get started
<jmv_> To better read the logs , I should better understand what is a tuple and the fact inside ...
<jmv_> That 's what's inside an event .
<pajac> krisv: thanks
<etirelli> jvm_: for your case, audit log is better... I don't think that looking at the generated code will have any value for you...
<jmv_> audit is something different from what I have with DefaultAgendaEventListener . afterActivationFired() ?
<krisv> jmv_: the audit viewer extracts the most useful information for you and shows it in a tree view
<jmv_> ok .
<jmv_> My rule run lives inside an application in a non-Drool project . Is that preventing me from using the audit view ?
<krisv> no, the log is an xml file, you just need to open that with the audit view
<jmv_> :)
After reordering results from Drools according to recency (probably
useless), and correcting the Euler parser output (was introducing extra rules),
I came to a more fundamental issue. To see that, I logged Drools events "After
Activation Fired", and named rule by file name and number, e.g.
rule=query.n3 0
.
The main query was this one :
{ ?OBJECT a ?CLASS . # 1
?CLASS a java:ConcreteClass . # 2
?OBJECT ?PROP ?VALUE . # 3
} => {
?OBJECT ?PROP ?VALUE . # 4
} .
which is translated this way into Drools
rule "query.n3 0"
when
Triple( $OBJECT : subject, predicate ==
"<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>",
$CLASS : object ) # 1
Triple( subject == $CLASS, predicate ==
"<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>",
object == "<http://java.sun.com/class#ConcreteClass>" ) # 2
Triple( subject == $OBJECT, $PROP : predicate, $VALUE : object ) # 3
then
Triple newTriple =
new TripleResult( $OBJECT, $PROP, $VALUE ); insert( newTriple );
end
Now the point is that, starting from a statement such as :
:myPanel a java:javax_swing_JPanel .
it should unify with both #1 and #3 . This seems to be a problem with Drools, I need to clarify. As a workaround, I added this rule. It is clearly redundant with a logical engine, but with Drools I'm not sure. But in one case, it made things better (NRI reduced).
{
?OBJECT a ?CLASS .
?CLASS a java:ConcreteClass .
} => {
?OBJECT a ?CLASS .
} .
Now when I test a small case in isolation, it works, which means that Drools can accept a single instance.
rule "multi crit"
when
Plate( $NAME : name, type == "desert" )
Plate( name == $NAME, $TYPE : type )
then
System.out.println( $NAME + ", " + $TYPE );
end
So I'm puzzled, Drools seems OK, but my translation doesn't work on large cases.
Statistics: rule Count 57, around 100 objects.
At least my rules are not suspect! Because they work, although slowly, with the Euler Prolog engine. But the translation is suspect, and so is Drools ...
What is a systematic of debugging a rule base that doesn't trigger when expected ?
This weed-end, I continued work on Drools engine for N3 logic.
I thought I needed to reorder results from Drools according to rule order and fact order, but there were other problems.

I would like to attend that. It's free, but would I be admitted? Mmy stuff is quite remote from that now.

Drools N3 engine: implemented fn:substring-after, at least so that case "order request" works almost as with Euler engine.
For the big NRI test case now we have a few seconds before getting the GUI, instead of hundreds of seconds with Euler-EYE !
The remaining root problem for the big NRI test case now is still to respect original order of properties in OWL:
sk_JFRAME_12_11_.pack( ) ;
Using Instanciator class, it would not be difficult to read an N3 project file and translate that into n3_project.Project file. But the reverse operation is not so obvious, when one wants to avoid ad-hoc code. Some way of converting a JavaBean into RDF is needed ...
Astronomy : select * from *
Politics : select idiots from ambitious
Handicraft : create table from_precious_wood
After some laborious work, I get something working with the Drools engine
almost like the Euler-EYE engine. The Actions for text fields and buttons work,
because the RDF list in Consequent is correctly implemented. The
log:uri
built-in is implemented, and the numeric comparison, at
least in some call modes.
There is a Drools Working Memory that stores the end-user data, but it's not visible since there is no load / save in the end-user (generated) application.
What is missing for "Déductions" GUI generation:
TODO
After upgrading Drools to the level of Euler-EYE, the plan concerning features is still here; the plan concerning internal design and implementation is:
There is a common theme in the 2 items above; instead of hand-made procedural code, we should use a declarative rule-based engine, just like in "Déductions" for GUI generation. Point 1 is important because this is the embryo of a multi-language, multi-platform tool. Point 2 is more complex because this is a bootstrap issue: a rule engine is needed to build a rule engine.
NOTE:
With the current Drools-N3 engine, there cannot be more than one value for a subject and a predicate. I don't think this is a severe limitation.
The current class is Instanciator. When processing RDF triples, we want basically to say:
This looks pretty simple! But it takes 646 low-level Java lines, specialized for a specific naming convention in input, and JavaScript+Java object on output. We must be much more flexible in input and output.
What is an instantiation in most languages ? Well there 2 cases: typed languages and weakly- or non-typed. The ingredients are:
I think of using a RETE engine, but I don't like Drools' syntax. Think of the number of pages it takes to describes the stuff ! They are stuck in an old variable instantiation-variable use scheme. Compare that to the flexibility of Prolog! So I'd like to try another engine, and/or wrap the OO RETE features into an N3 or Prolog-like vocabulary or language.
I'm reading Hammurapi PDF manual. This is interesting, and contrary to Drools:
Hammurapi rules' knowledge base can be held in memory or in persistent storage.
The way Hammurapi expresses rules is interesting: in ordinary in Java
language inside Rule.insert()
methods. But it's not what I'm
lloking for. Reading Hammurapi made me thing of using JSR94 API instead of
plain Drools API.

I wanted to make a SWI compatible source from a Yap source, euler.yap, which is the implementation of Jos De Roo's Euler N3 logic inference engine.
First I replaced numbervars
with number_vars
everywhere, because this is a predefined predicate on SWI but not on Yap . Then
these two conditional blocs do the trick:
:- expects_dialect(yap).
:- if( prolog_flag( dialect, swi )).
:- style_check( -atom ).
:- endif.
% ......
:- if( prolog_flag( dialect, yap )).
% these are not really needed on Yap, but it's more declarative :)
:- use_module(library(regexp)).
:- use_module(library(charsio)).
:- endif.
Now I have something that compiles on both SWI Prolog and Yap, and I can use the superb SWI Prolog IDE. For more complex problems, I advise to read this paragraph in SWI manual;

And the result on NRI, with expandForms disactivated, and the comprehension limit raised to 600, is :
#ENDS 1542376 msec
With expand sub Forms activated , there was no problems with cycles in the class-property graph, but the CPU time raises now to 1799 seconds!
Note that the form with expand sub Forms is just for demonstration purposes; it has no scroll bars and is larger than the screen.
#ENDS 1798532 msec
Further optimisation attempted
I tried yesterday's point 4, by adding this global settings that is false by default:
app:globalSettings app:justGenerateReachableClasses true .
I thought that the app:isReachableFrom
relation is expensive to
compute. Applying that "enhancement", we go from 7s to 116s on the "order
request" case. The reason is probably that we can't eliminate the support
classes when doing this:
{
?END_CLASS a owl:Class .
(?SCOPE 1) e:findall (
?X { app:globalSettings app:justGenerateReachableClasses ?X . } () ) .
} => {
?END_CLASS gui:hasForm ?FORM .
} .
Still trying to run the nridb.n3 case. Jos added trace for reasonning steps.
I found some problems and got ideas, but not the root cause yet .
When watching the run with --debug
, I saw that much time is
spent on navigating the relation between class and property and the class
hierarchy .
Computing the transitive javapr:contains
relation , transitive
closure of javam:add
is useless , as this was added for testing
purposes. It's the same for gui:contains
. I don't don't why they
get computed at all; I thought that the Euler-SEM algorithm was goal directed.
Anyway this is probably not the root cause of the infinite loop, but removing
the unused stuff may help to find the problem. In fact the CPU on test_person
went from 20s to 15s by removing these 2 relations.
At one time I thought that a cyclic relation between class and property was the problem, like this. But this runs fine.

To implement point 3 (split the inference into steps), I need a way to query the intermediary results. The query used in current Déductions Project is expensive, as it uses inheritance on the set of Java classes used:
{ ?OBJECT a ?CLASS .
?CLASS rdfs:subClassOf java:java_lang_Object .
?OBJECT ?PROP ?VALUE .
} => {
?OBJECT a ?CLASS .
?OBJECT ?PROP ?VALUE .
} .
Another inconvenient is that we get several reponses
?OBJECT a ?CLASS .
for a single ?OBJECT, so we need to filter out the abstract classes manually in the N3 to Java translation, and also rely on these triples to come out of Euler in the right order.
There is a simpler way to query, for the intermediary or final results. Simply add a marker property meaning : "this object belongs to the results" . So the query would be :
{ ?OBJECT a :result .
?OBJECT ?PROP ?VALUE .
} => {
?OBJECT ?PROP ?VALUE .
} .
But this would change too many rules, this is better:
{ ?OBJECT a ?CLASS .
?CLASS a java:ConcreteClass .
?OBJECT ?PROP ?VALUE .
} => {
?OBJECT ?PROP ?VALUE .
} .
I can also make use of scoped computation of most Derived Classes for a given instance.
I have problem with the NRI SQL model that passed though RDBToOnto converter . The tool chain fails:
SQL ==> N3 ==> my rules for GUI construction with Euler ==> error(comprehension limit exceeded) ! :(
I try W3C's RDF validation service:
http://www.w3.org/RDF/Validator/
And WonderWeb project's OWL validator:
http://www.mygrid.org.uk/OWL/Validator
They say nothing special.
But Pellet (stand-alone or embedded in Protégé) says this:
~/apps/pellet-2.0.0-rc4% ./pellet.sh consistency ~/apps/RDBToOnto_1.2_beta/output/nridb.owl
1 févr. 2009 17:31:12 org.mindswap.pellet.KnowledgeBase consistency
ATTENTION: Inconsistent ontology. Reason: Plain literal "1" does not belong to datatype http://www.w3.org/2001/XMLSchema#int.
Literal value may be missing the rdf:datatype attribute.
Consistent: No
Reason: Plain literal "1" does not belong to datatype http://www.w3.org/2001/XMLSchema#int.
Literal value may be missing the rdf:datatype attribute.
Indeed the original SQL has INSERT INTO declarations, that translate in RDF without datatype indication, e.g. :
:complic_clin_3
a :complic_clin ;
:COMPLIC_CLIN_ID "3" ;
:complic_clin-EN "Intracerebral hematoma" ;
:complic_clin-ENABLED "1" ;
:complic_clin-FR "Hematome intracerabrale" .
Then I run again RDBToOnto converter, this time specifying no instance , and then Pellet says :
~/apps/pellet-2.0.0-rc4% ./pellet.sh consistency ~/apps/RDBToOnto_1.2_beta/output/nridb2.n3
Consistent: Yes
However Euler EYE still says:
** sem error(comprehension limit exceeded)
% YAP execution halted
So I go back to suspect my rules, or rather a combination of my rules plus this 16 classes, 32 objects and 59 data properties OWL model.
Jos pointed out that some rules were similar to :
:a :moreInterestingThan :z.
{?X :moreInterestingThan ?Y} =>
{?Y :moreInterestingThan ?Z}.
It must be some longer cyclic implications involving my rules, plus property domains and ranges, as there is no sub-classes at all.
I began to play with queries on the rules themselves, e.g. this rule detects the rules having a triple with property javapr:projection in the consequent :
{ ?SOMETHING => ?CONSEQUENT .
?CONSEQUENT log:includes { ?FORM javapr:projection ?JP . } .
}
=> { ?SOMETHING javapr:creates javapr:projection } .
But this would be difficult to detect vicious circle through such queries.
I could also by dichotomy remove rules until error dispappears. My best hope is to trace reasonning steps.
I wonder what exactly means :
[ e:counterModel true].
and how is it different from an empty answer.
Now that Luc Peuvrier is here, I need to tidy all I can :) !
The trick is to use the forms computed at design time by Euler as prototypes that are cloned at run-time. The ObjectBehavior class maintains a correspondence Map between GUI Container and RDF Object Id , which allows to keep track of the instance edited by the GUI component, without modifying the latter.
This is quite fragile and roughly acceptable for demo. purposes; the right implementation will be to use Drools engine at run-time.
Also submited in Déductions:
I took my former colleague Thomas Cenni's NRI-DB medical database . I passed it though RDBToOnto converter (a very nice tool BTW) , got a 2600 lines N3 - OWL file. Yap Prolog still runs now, after 360 minutes !
Converting my local N3 project (EulerGUI project) into a equivalent project referencing the SF.NET Subversion URL's :
1,$s=file:/home/jmv/src/deductions/n3/=http://deductions.svn.sourceforge.net/viewvc/deductions/n3/=
Marc Godin is studying fishes :
Only dead fish swim with the stream.
The Java components I create currently for forms are in fact prototype objects. A single form can be instanciated several times simultaneously, for multi-valued fields. They should not be shown inconditionally at startup time. Instead, when user clicks on a button for an Object Property, the forms are instanciated and embedded in current frame or in a popup window. In java Swing, a Component cannot be embedded in two different containers.
At runtime, a form or an input field instance is associated to an edited instance, which corresponds to a triple in RDF. But we are editing a specific instance of triple object in the triple store, and we are modifying it in place.
The simplest would be to have an inference engine at runtime. But we don't have one right now (and also infering a form every time a user clicks a "create" button might be too slow). So a flexible design is needed here.

A tip from Kos de Roo:
> - is there a multi-line N3 comment ? ( like /* */ )
What I sometimes do is
[ comment """
your_n3_to_be_skipped
""""].
I take the opportunity to write the development plan as an N3 document.
Development plan for Déductions as an N3 document.
I realize that e:findall (which is a wrapper around the ISO Prolog predicate findall), doesn't work like this:
{ (?SCOPE 1) e:findall (
(?SUBTYPE) { ?SUBTYPE rdfs:subClassOf ?TYPE } () )
} => {
?TYPE gui:mostDerivedClass true
} .
The variable ?TYPE must be bound somehow for this to work (bug or feature?). For instance with gui_generic.n3 from the Déductions ontology I can add this in the antecedent :
?TYPE rdfs:subClassOf gui:Widget .
Then I get the expected solutions:
ns1:DatatypeInputWidget ns1:mostDerivedClass {}.
ns1:ObjectInputWidget ns1:mostDerivedClass {}.
ns1:Form ns1:mostDerivedClass {}.
I am surprised by the empty {}, but that is not a problem, I can replace true in the consequent with 1 .
Note that this result depends on rpo-rules.n3 .
Then I try another rule:
{ ?TYPE rdfs:subClassOf gui:Widget .
(?SCOPE 1) e:findall (
(?SUBTYPE) { ?SUBTYPE rdfs:subClassOf ?TYPE } (?SUBTYPES) )
} => {
?TYPE gui:subClasses ?SUBTYPES
} .
But here I get only one solution:
ns1:ContainerWidget ns1:subClasses (ns1:Form).
although I expect another solution :
ns1:InputWidget ns1:subClasses (ns1:DatatypeInputWidget ns1:ObjectInputWidget).
All this works the same with SEM Java and EYE.
Note that this is just an example. In the actual rules of the Déductions ontology I need to find the most derived classes of business (user) classes like purchaseorder.owl; the aim is to make GUI buttons to create instances of the most Derived Classes.
Jos' answer
Why not simply have
{ ?TYPE rdfs:subClassOf gui:Widget . # owl:Thing .
(?SCOPE 1) e:findall (
?SUBTYPE { ?SUBTYPE rdfs:subClassOf ?TYPE } ?SUBTYPES )
} => {
?TYPE gui:subClasses ?SUBTYPES
} .
Using (?SUBTYPES) for the resultset was enforcing that there should only be one result item.
I find Protégé convenient for exploring and visualizing an ontology (but not for writing one, were I prefer to write N3 source). First, convert the N3 into RDF:
cwm gui_generic.n3 --rdf > /tmp/gui_generic.rdf
Note that this would be a convenient feature in EulerGUI: adding a button to export an N3 file as RDF. Then the resulting RDF file can be opened in Protégé:
Wouldn't it be possible to create a special N3 predicate for debug trace printing that could be added in antecedent or consequent ? Something like :
e:trace "My message" (?OPTIONS).
where options could be empty or "print_all_variables", "print(?MY_VARIABLE)", etc . When empty, it could print a count of times called, and maybe some indication of the current state, like current CPU time, number of predicate called, etc.
In this line of thought , I'd like to have a note on how to debug N3 rule bases; I could write a first draft, and you could add stuff from your vast experience.
I reiterate my suggestion to use the variable name for new blank nodes' Id .
I'll visit a customer friday, to enhance a knowledge keeping application based on Access. While thinking on ways to reuse existing VB code, I thought about the Mono project , that could run VB code on Open Software platforms. BTW Mono could be one of the back-end platforms for Déductions. I don't know enough of the Access VB dialect. Does it use standard portable API like ADO.NET ? Well, the answer is that it can use one or more of several API's that Microsoft did over the years : Microsoft Access Object Library, several flavors of DAO (Data Access Object), ADO.NET . See MS database API's, http://en.wikipedia.org/wiki/Visual_Basic_for_Applications

The specification is here : Manage inheritance :
If the Property type has any subclasses, only the most derived class(es) must be exposed to the user as explained in paragraph "Create or link". If not, the Property type itself is exposed to the user.
It used to work this way in java_projection-rules.n3 revision=23 :
{
javapr:thisApplication app:platform app:Java .
?W a gui:ObjectInputWidget .
?W gui:label ?LABEL .
?W gui:type ?TYPE .
?SUBTYPE rdfs:subClassOf ?TYPE .
?SUBTYPE rdf:label ?TYPE_NAME . } => { ?W javapr:projection ?JP . ?JP a java:javax_swing_JPanel . ?JP javam:add ?JLABEL . ?JP javam:add ?JBUTTON . ?JBUTTON a java:javax_swing_JButton . ?JBUTTON java:text ?TYPE_NAME .

} .
Waiting for a hint from Jos on how to use e:findall .
I updated the documentation with install and usage of latest Euler EYE processor (with 100% Prolog engine replacing old Java N3 to Prolog translator),
so that EulerGUI is about ready for a new release.
Jos corrected the first error, not the second one. He also corrected the missing object in triple error.
I implemented the strings delimited by """ for Java code generation. So now I can really work with the new EYE engine.
COMMITED:
- add support for EYE (new stand-alone Yap engine)
- Euler installation directory is searched in expected places (EULER_INSTALLDIR)
Works on simple cases, but on deductions/n3/test_order.n3p
we get this error:
# ** main/0 error(instantiation_error,[atom_codes/2|local_sp(142690704,143065392,[],[])])
# ** main/0 Failed to finish
However, it works well with Euler Yap through Codd and test-as option .
I get the same error on deductions/n3/test_person.n3p .
And on deductions/n3/euler_project.xml.n3p , there is a different error : an object part is missing in an triple at third line :
_:sk7 a ns4:javax_swing_JFrame. _:sk7 a ns4:javax_swing_JFrame.
_:sk7 a ns4:javax_swing_JFrame. _:sk7 ns4:title """generated by Deductions framework""".
_:sk7 a ns4:javax_swing_JFrame. _:sk7 ns4:visible .
Classes having subclasses used to work (in example deductions/n3/euler_project.xml.n3p ), but I broke that when working on purchase order. Now I need a way to say : "when a Class has subclasses , do this with the most derived classes, and otherwise do that with the Class itself ".
For this I'm trying to make use of "Scoped negation" in N3, namely log:notIncludes and e:findall with an empty result set.
WORK IN PROGRESS
COMMITED:
This is what I get today with the purchase order test :
Everything is expanded, for instance the "hasCustomer" button is followed by a corresponding "Customer" titled border (sub-form), etc . Soon we will connect the sub-forms to properties instances, and offer a choice of expanding sub-forms or not. And of course the "hasCustomer" button will create a new customer. However in this case "hasCustomer" is a one-valued mandatory property so behavior can be simplified, by expanding the sub-form unconditionally.
Working on EulerGUI project test_order.n3p , including ontology purchaseorder.owl .
COMMITED
ISSUES
:hasLexicalRespresentation (sic) ; it has rdfs:domain :Identifier, and Identifier is refered indirectly by its subclasses ProductCode and CustomerID, for example CustomerID has no property of its own, it has property "hasLexicalRespresentation" though its superclass Identifier; this is not implemented.
:hasStatus ( OK, it is a property of OrderConfirmation only)
Read the FAQ about openJDK and the Open Source Java .
Also had a look at the JDK7 WatchService class . I don't know whether on Linux the JDK7 WatchService uses FAM (File_alteration_monitor) .
Also searched "file notification java" on sf.net .
Finally, jnotify looks good.
domain, range, subClassOf, subPropertyOf
What I did when splitting rules because of non mandatory rdf:label resulted in cleaner design.
Now I must do the same refactoring for Buttons for Object Properties, whose "text" property comes also from rdf:label.
COMMITED
I had a look back at my Generic JavaBean editor included in ecolosim project . It has goals similar to GUI generation in Déductions project, except that in ecolosim the starting point is a set of Java classes respecting the JavaBean naming conventions, whereas in Déductions it starts from an OWL ontology. An important limitation of GUI generated in ecolosim is that properties of non-primitive types are always considered embedded (there is no way to create a linked data structure). In Déductions accurate GUI's will be inferred from the input ontology, taking in account all constraints (cardinality, linked or embedded, ordered or not, set or not, etc).
For some reason files on the SVN repository were executable: remedy:
svn propdel svn:executable *.n3
svn commmit
I think that what I have been doing for GUI generation is just a particular case of object graph transform. The limitation compared to XSLT or forward chaining rule engines (Drools) is that there is no rule priority, or default reasoning. This is a limitation, but also a cleaner way to do, since rules are both constructive and logical implications.
I solved the yesterday's problem , by using the RDF ID when there is no rdf:label (no other way).
{
?FIELD gui:inputWidgetSpecification ?PROP .
?PROP log:uri ?URI .
( ?URI "#" ) fn:substring-after ?PROPLABEL .
} => {
?FIELD gui:label ?PROPLABEL .
} .
But now I have two fields and labels per property ! This rule in the current implementation of the Java projection should be split :
{
javapr:thisApplication app:platform app:Java .
?W a gui:DatatypeInputWidget .
?W gui:label ?LABEL . ?W gui:inputWidgetSpecification ?Property . ?Property rdfs:range ?Type . } => { ?W javapr:projection ?JP . ?JP a java:javax_swing_JPanel . ?JP javam:add ?JLABEL . ?JP javam:add ?JTEXT_FIELD . ?JLABEL a java:javax_swing_JLabel ;
java:text ?LABEL .
?JTEXT_FIELD a java:javax_swing_JTextField .
?JTEXT_FIELD java:columns 10 .
:GUIHelper javam:addFieldBehavior ( ?JTEXT_FIELD ?Property ?Type ) .
}
Precisely, both elements in red are removed, and this triple is added in the consequent to keep track of the concrete newly created Label widget :
?FIELD gui2:label ?JLABEL .
Then a new rule is added, to replace what was removed :
{
?FIELD a gui:DatatypeInputWidget .
?FIELD gui:label ?LABEL_TEXT .
?FIELD gui2:label ?JLABEL .
} => {
?JLABEL java:text ?LABEL_TEXT .
} .
I found a good enough (for now) way to solve the default values issue. In app_gui-rules.n3 , putting the default rule (use RDF ID) before the specific rule (use rdf:label) , the JavaScript assignments are in the right order, override one another, and the resulting GUI is OK :
sk9_11_.text = "eulerArguments" ;
sk9_11_.text = "euler Arguments" ;
I realise that the Purchase Order exemple doesn't output any form field, just because the rules (app_gui-rules.n3) expect an rdf:label on each property. I should decouple the rules concerning label from the ones concerning input fields, or even better make a rule to enforce that undocumented widgets such as input widgets should be accompanied by a GUI label.
But the most important thing is that somehow I create a label out of the property Id , e.g. "has Customer" from hasCustomer
here:
:hasCustomer
a owl:FunctionalProperty , owl:ObjectProperty ;
rdfs:domain :OrderRequest ;
rdfs:range :Customer .
First this is not very clean to use an ID, and second we should avoid default reasonning, which is non monotonic logic. Anyway as far as I know, there is no way to do non monotonic reasoning with N3 logic.
A new project window must have an initial directory for file chooser taken from the current window.
When closed, a secondary project window should not close the application.
Slowly emerging after a cold ...
I'm thinking of using Drools engine for non-monotonic stuff, especially generating JavaScript code (see 2008-12-24).
Also to generate XHTML I would need some framework allowing to go from RDF repesentation to XML.
I'm thinking of using JRDF instead of my own simple Triple class . It would be good either to wrap a JRDF implementation so that it also stores on a Drools WorkingMemory , or completely rewrite an implementation of a JRDF interface in terms of a Drools WorkingMemory .
Or I can simply take inspiration on JRDF API, and basically keep my stuff for now. To implemeted my generated GUI, this thread is relevant :
[Jrdf-general] Updating triples
They claim to have taken inspiration from Sesame and Jena .
http://jrdf.sourceforge.net/0.5.5.4/doc/javadoc/index.html
We need to refactor java_projection-rules.n3 to create an additional layer with abstract widgets generalizing Swing and HTML.
This layer will be useful also for generating SWT with Wazaabi2 by Olivier Moïses, or generation of GWT, etc.
The straightforward solution in the line of what was done before is to replace strings like this in java_projection-rules.n3 :
java:javax_swing_JXXX ==> widget:XXX
for example :
java:javax_swing_JButton ==> widget:Button
And then rules must be added to translate widget:XXX into the kind of widgets for the plateform considered.
In the Java Swing case, this is particularly simple, since the name of unified widgets are just the Java Swing names with the initial J removed.
So implementing this projection
widget:Button ==> javax.swing.JButton
with a rule engine is maybe like smashing a fly with a hammer.
Such an implication is wasting computing power ;
{ ?WID a widget:Button } => { ?JAVA a java:JButton }
and besides it is not accurate, because for several widget:Button we will get a single java:JButton, unless we add this in the LHS :
?WID javapr:projection ?JAVA
with cardinality restriction 1 on javapr:projection, or describe it as an functional property .
Here is a test I did with Drools before writing an automated transform for EulerGUI. One can see that N3 is more compact than Drools . An annoying thing is that implicit variable binding is not allowed, which make Drools less declarative than N3 and Prolog, and complicates the translation.
package com.sample
import com.sample.DroolsTestTriples.Triple;
rule "OWL transitive property"
// before writing the generator from N3 to Drools,
// I did a hand translation into Drools of this N3 definition of OWL TransitiveProperty
// in http://eulersharp.svn.sourceforge.net/viewvc/eulersharp/trunk/2003/03swap/rpo-rules.n3
// {?P a owl:TransitiveProperty. ?S ?P ?X. ?X ?P ?O } => {?S ?P ?O}. when // this design works but is not well adapted to automatic translation, // because in Drools there is variable declaration and then variable reference Triple( $P: subject , predicate=="a" , object=="owl:TransitiveProperty" )
Triple( $S: subject , predicate == $P, $X: object )
Triple( subject == $X , predicate == $P, $O: object ) // trying to split variable declaration and variable reference // but Drools doesn't allow yet implicit variable binding // cf chat with Mark Proctor 2008-11-09 :-( /* Triple( $P == subject , predicate=="a" , object=="owl:TransitiveProperty" )
Triple( $S == subject , predicate == $P, $X == object )
Triple( subject == $X , predicate == $P, $O == object ) */ then insert( new Triple( $S, $P , $O ) ); end
<jmv> Is there an API to populate a rule base ?
<jmv> I want to translate rules in N3 into Drools

<etirelli> jmv: what do you mean by "populate"?
* mfossati (~be031ba3@docs2.codehaus.org) a rejoint #drools
<jmv> instead of parsing a Drools source, I want to call methods to create rules, much like DOM in XML
<etirelli> jmv: you can use the classes we call Descriptor Model... you just need to be aware that although their are mature and rarely change from version to version, they are not considered public APIs and may have minor changes over time
<jmv> OK
<etirelli> jmv: http://anonsvn.jboss.org/repos/labs/labs/jbossrules/branches/4.0.x/drools-compiler/src/main/java/org/drools/lang/descr/
<etirelli> PackageDescr is the root class
<etirelli> and it is the input to the rules compiler
<jmv> I see it has addRule(final RuleDescr rule) , and so on .
<jmv> No code sample I guess ?
<jmv> calling the rules compiler and run ...
<jmv> Looking the Javadoc, I see PackageBuilder.addPackage( PackageDescr )
<etirelli> yes, PackageBuilder is "the" compiler
<etirelli> and examples are only the integration tests.. since it is not really a public API
<etirelli> to learn how it works, right sample rules in DRL, and use the DrlParser to parse them into descriptors... inspect the descriptors to see the generated result
<jmv> you mean *write* sample rules ?
<jmv> it makes sense
<jmv> time permitting, there might be a Drools engine here : http://sourceforge.net/projects/eulergui/#
<jmv> which would open the possibility to mix RDF, OWL, N3 , with Drools
<etirelli> yes, *write* :)
<etirelli> cool :)
<etirelli> jmv: conan is interested in RDF and OWL support :)
<jmv> i think we talked here 2 years ago about that ...
<jmv> there are several API 's to read RDF , notably Jena
<jmv> I use Jena ; there is Sesame too
<jmv> I use Jena to parse RDF and write N3 , which is a more human-readable RDF
Using plain vanilla Objects:
t = new Object() {
a :"aa" ,
b : 11
};
alert( t.a + " " + t.b + " " );
In fact new Object() is not necessary; it is a plain JavaScript object, i.e. an associative array.
This creates an object graph:
a = new Object();
a.b = new Object();
a.b.c = "vvvv" ;
alert ( a.b.c );
This does not work b ecause Runnable is abstract :
var r = new java.lang.Runnable();
r.run = function() { alert('hello'); } ;
java.lang.Thread(r).start();
Need to do this:
var r = new java.lang.Runnable() {
run : function() { alert('hello'); } };
java.lang.Thread(r).start();
Using JSON in JavaScript it is possible to stringify such an object :
t = new Object() {
a :"aa" ,
b : 11
};
s = JSON.stringify(t);
alert( s + "--- "+ JSON.parse(s).a );
Note that in json2.js the JavaScript incantation to introspect the JavaScript object is :
for (k in value) {
if (Object.hasOwnProperty.call(value, k)) {
At last the Deductions project is on Sourceforge ! The Subversion repository is populated with N3 sources and the HTML that are on jmvanel.free.fr . There is a meeting on november 15th, and possible work with Olivier M. on an SWT backend.
The Deductions rule base can generate a crude window; but the multiplicity is not taken in account. And for now there is nothing for runtime behavior and storage in end user application. But it is declarative all the way :-) .
One of the goals is to remake the Euler GUI application with the Deduction technology.
Saw interesting features: N3Document, definitiveDocument, definitiveService .

I developed a little Java class, Project, to shortcut the intermediary Web server and reuse the same rules and facts compiled in Prolog for several queries. It's a minimal file based wrapper for Euler SEM reasoning services; a Project owns a Set of N3 sources, N3 queries, and possibly Prolog sources.
On top of Project, I did a small Swing GUI. It's still barely usable, but it already can load several N3 sources and queries and lunch the inference process. I plan to add an RDF reader through CWM and Jython.
I used threads to accerate on a 4 core machine. I learn XPCE.

Here is the desired workflow:
designer --> DL Ontology --> Prolog code }
designer --> Prolog rules } --> Application
user --> database update --> fire rules --> OK or explaination
user --> query --> answer
The Prolog rules are expressed with the same predicates and reified concepts as those translated from the initial DL (Description Logic) Ontology, and are the part of the knowledge that is too complex to be part of the DL Ontology. An example of a non-DL rule is here:
hasParent(C,P) ¿ hasBrother(P,BP) ¿ hasUncle(C,BP)
If I understand well, the workflow of Euler is :
designer --> DL Ontology --> Prolog code
designer --> N3 rules and queries --> Prolog code
user --> N3 query --> --> Prolog code --> proof including variable binding
How can Euler be wrapped or adapted to fit the above workflow ?
I could shortcut the Codd server and run all in a single Prolog process :
pl -f ./sem.pl -t main. < ./test008.in
A link on Euler paths: ???
This file should not be here :
classes/euler/Support.java
It would be good to include in the distribution a file run_euler.sh :
java -classpath bin/Euler.jar:bin/Euler_Tests.jar:lib/tuprolog.jar euler.EulerRunner $*
and a file run_codd_server.sh :
java -cp bin/Euler.jar:bin/Euler_Tests.jar:lib/tuprolog.jar euler.Codd $*
I made additions to the Euler FAQ .
Q: The output of Euler is a proof in N3. Is there a way to shortcut that and produce a Prolog output ?
A: ??? DEBUG in progress
Q: What is the ontology for the proof answers of Euler ?
A: One can see that the r: namespace prefix is used; it is declared as
pfx('r:','<http://www.w3.org/2000/10/swap/reason#>').
just follow http://www.w3.org/2000/10/swap/reason# and that is the ontology; it has comments for all the concepts.
Q: Note that with the latest version of Euler and cwm this gives a parser error in cwm :
pl -f ./sem.pl -t main. < ./test008.in > test008.out.n3
cwm --n3 test008.out.n3 --rdf --pipe
...
AttributeError: 'tuple' object has no attribute 'close'
However this gives no hint:
pl -f ./sem.pl -t main. < ./test008.in
PENDING !!!!!!!!!!!
Q: How would you do to integrate Euler into a Java GUI such as SWOOP or Protégé ?
A: it depends on what one want to achieve: one feature could be to write an N3 rule and display the proof
Q: What is the difference between Euler and classical DL reasonners such as Pellet and FaCT++ ?
A: Euler is an all-purpose logical query engine. Reasonners process the ontology globally, thus achieving much better performances than processing the classes one by one.
Q: How can one use Euler to implement the services of a DL reasonner, i.e. classification and detection of unsatifiable classes?
Q: Before reading more about the Euler path algorithm, I wonder if using a tabling Prolog such as XSB would not achieve a similar effect, that is to avoid infinite loops and memoize the calls already encontered.
A: A We took the option of a reasoner written in Prolog instead of taking Prolog as a reasoner and there are many reasons for that: no need to declare which predicates should be tabled, having a proof output (in N3), supporting Coherent Logic, etc..
Q: What is Coherent Logic ?
A: Look at the last chapter of
http://folli.loria.fr/cds/2006/courses/Bezem.Nivelle.IntroductionToAutomatedReasoning.pdf
(the whole course btw is very good!)
Q: Which crucial feature made you switch from Yap and tuProlog to SWI ? The semweb libraries ?
A: No, performance
Q: Could I run the current SEM (Skolem Euler Machine) on tuProlog ?
A: not yet; I would also consider to use jTrolog (which has better performance) https://jtrolog.dev.java.net/
Q: What are the advantages of the current SEM (Skolem Euler Machine) ? More expressive power or performances ?
A: It has more expressive power in that one can have existentials and disjunctions in the conclusion. This allows to find e:falseModel and e:counterModel but I still have to investigate the proof expression of those. For Horn Logic the engine speed is not degraded which was quite a challenging task :-)
Q: Is it radically new with respect to old Euler proof ?
A: ???
Q: I tried to read the thesis mentioned on the site; it's not easy; also there is a different language ML or haskell .
A: The most relevant paragraphs are mentioned in the FAQ.
Q: do you re-use OWL/RDF ontologies or is all written by you ?
A: there is a lot that we try to reuse esp data sources like
http://bioontology.org/ncbo/faces/index.xhtml
http://esw.w3.org/topic/SemanticWebForLifeSciences
etc
Q: What is the difference with the N3 parser in CWM, apart apart from Euler being in Java ?
A: They are very close wrt to the language that they can parse.
Q: What is the difference with the N3 parser in Jena ?
A: The Jena N3 parser can't cope with {} formulae which is crucial for N3 Full support.

Why?
How?
in case of ambiguous words, use a reference to a WordNet sense (synset)
While I'm practicing on this exercice in AIMA I try to express in first order logic in an elegant way that :
Which amounts to declare that if the parts are disjoint [a bit of MathML] :
and to enter enough mathematic knowledge to make Prover9 infer this:
∀s ∈S,
and then
Thinking later, I'm not sure to what extent I can formalize all that in FOL.
So I'm reading about fisrt order axioms for set theory: Set Theory in First-Order Logic: Clauses forG6del¿s Axioms. I's funny that one author of this is W. McCune, the developper of Prover9 !
So I feel a need to read again about Upper ontologies: SUMO, Dolce, OpenCYC, BFO, UMBEL, etc.
I found some comparisons on the Web
From the Sumo site one can enter an English word and the corresponding formal term in SUMO for each WordNet sense (synset) will be displayed.
The open source Texai project has released the RDF-compatible content extracted from OpenCyc.
A bad sign: the research.cyc site is down this saturday. It's too bad, because on top of what Opencyc has, it includes, according to Wikipedia, a large lexicon, English parsing and generation tools, and Java based interfaces for knowledge editing and querying.
Dolce has a detailed (349 pages) description.
There is, as everywhere, the Babel effect:
There is at least one exchange format for FOL (first order logic), the one used by the TPTP (Thousands of Problems for Theorem Provers) Problem Library, which is a library of test problems for Automated Theorem Proving (ATP) systems.
The most used format for ontologies including logic rules is KIF; generally an OWL extraction is provided; but OWL doesn't provide rules.
In this sigmakee CVS directory, the SUMO file is called Merged.kif.
In the SUMO source I found this axiom about finite sets:
(=>
(instance ?SET FiniteSet)
(exists (?NUMBER)
(and
(instance ?NUMBER NonnegativeInteger)
(equal ?NUMBER
(CardinalityFn ?SET)))))
I'm practicing on this interesting exercice in AIMA, using Prover9. I won't put my solution here, thinking of teachers who are using this for home work, although I think that having a corpus of solutions is a good way to learn.

While searching for OCL + FOL, I found Isabelle, which is a kind of generic logic tool (not only FOL, but Higher Order Logic, etc).
This article uses Isabelle: HOL-OCL: Experiences, Consequences and Design Choices.
William McCune, the author of Prover9 and Otter, answered me !
Thanks for the feedback. Prover9 has some similarities with Prolog
(language and theorical basis), but it should not be thought of as an
extension of Prolog. The search method is entirely different.
First, there is no backtracking. Prover9 can do a goal-oriented
search, but instead of backtracking, it explores multiple paths
simultaneously (it can do this because it stores intermediate clauses).
Second, Prover9 is designed to prove theorems, not answer queries.
One can recover the variable substitutions by using an "answer attribute".
Below is an example of using Prover9 to simulate a Prolog computation.
This is only an exercise, because it's very inefficient.

% ourselves and put it in "assumptions".
% Find the pairs of lists that can be appended to give [a,b,c,d].
% Note in the output that each pair is produced twice. This
% is not a bug. It's just the way Prover9 does its search.
-append(X, Y, [a,b,c,d]) # answer(f(X,Y)).

My (JMV) comment: you can't use the answer "attribute" in unrestricted formulas, you have to convert then by hand to clausal form first, otherxwise you get this message:
Fatal error: Answer attributes on non-clausal formulas cannot contain
variables
I subscribed to the CHR mailing list; there are quick responses to my newbie questions by the bosses themselves, Tom and Thom.
I ordered Tom Schrijvers' 2003 book "Essentials of Constraint Programming".
I'm testing the Blog feature on Google: http://jmvanel.blogspot.com/
Fedora 8 is arrived!
I updated to Amaya 10.1 on Fedora 7. It's quite convenient to write my Blog this way. Of course there is the hassle of uploading. But on Google JavaScript editor (mail, docs, or Blog) it tends to be quite slow, because of general slowness and memory consumption of Firefox.
Discovered Tom Schrijvers' Declarative Languages Blog . Tom is the maintainer of CHR.
Among other news, he started a type checker library in (SWI-)Prolog: type_check.pl. Using this library, you can use Mercury-style type declarations and predicate signatures. It's a migration path to Mercury, and also it's more flexible than Mercury, because typed Prolog code can call and be called by ordinary untyped Prolog code.
Had a look at the ODBC interface in XSB manual 2:
| ?- odbc_import(¿Test¿(¿TId¿,¿TName¿,¿Length¿,¿Price¿),test).
yes
This way the SQL table "Test" is made available as the predicate test.

I wrote my first CHR rule! I modifed db_family.pl: Family relations (deductive database)
this way :
mother(X,Y) ==> parent(X,Y).
And then this query
parent( jmv, sim ), mother( simone, jmv ).
gave more results.

I saw the TV interview of Charles Simonyi :

I also read the Wikipedia page on Intentional Programming . It's clear that Intentional programming has part of the thruth. But also the product that personifies the concept is probably a big fat GUI with a proprietary file format, the triumph of proprietary software. Not what people want in 2007. They want their design efforts to be saved in an open and durable format. Guess what it is, dear reader ? OWL. There is no other. And people in 2007 want flexibility. They want to use today's tools and source code with emerging paradigms.
My solution is :
annotate available existing modules and libraries with more semantic:
With a suitable inference engine and rules, plus a semantic search engine, plus a suitable GUI, this can enable to plug any annotated module to an exiting application. Remember that, like in eclipse, plugins are a composite structure, i.e. a module can have any granularity. So in theory this can solve the application building problem, in a top-down way. Of course, you'll still need develop features that exist nowhere. Also you'll still face the Babel effect on programming languages. But connecting different languages is "just" a matter of correspondance rules and, again, protocol state machines. So connecting different languages is automatizable; it's mainly an issue in performance and global architecture.
