I have asked on stackoverflow, perhaps somebody here knows the answer
I try to add a bit of ontology to a (public) RDF dataset (wordnet),
specifically I need to differentiate between |LexicalEntries| for Verbs
and Nouns, separated as two subclasses. Following examples on the web
and in the OWL standard, I assumed that
|:LexicalEntryNoun a owl:Class ; rdfs:subClassOf [ a owl:Restriction ;
owl:onProperty wn:part_of_speech ; owl:hasValue wn:noun ] . |
should build a class |LexicalEntryNoun|, but the query (in jena fuseki)
|prefix : <http://gerastree.at/2017/litonto#> SELECT * WHERE { ?s a
:LexicalEntryNoun. } |
gives an empty result. The two URI which should be returned are included
in the class represented by a blank node, which stands for the
restriction, but are not reported as |LexicalEntryNoun| as reported in
other queries.
i am new to OWL and do not find many examples of OWL in turtle syntax.
Where is my error? Thank you for help!
I constructed a very small subset of data which is loaded together with
the OWL reasoner |http://jena.hpl.hp.com/2003/OWLFBRuleReasoner|:
