Hi all,
I want to know how can i index and search a semantic document like rdf/owl
document using lucene.Does lucene support indexing of semantic documents.please
provide some sample example.for example if i have a small ontology of
faculty.owl as
<owl:Class rdf:ID="associateProfessor">
<rdfs:subClassOf rdf:resource="#academicStaffMember"/>
</owl:Class>
<owl:Class rdf:about="associateProfessor">
<owl:disjointWith rdf:resource="#professor"/>
<owl:disjointWith rdf:resource="#assistantProfessor"/>
</owl:Class>
<owl:Class rdf:ID="faculty">
<owl:equivalentClass rdf:resource="#academicStaffMember"/>
</owl:Class>
<owl:ObjectProperty rdf:ID="isTaughtBy">
<rdfs:domain rdf:resource="#course"/>
<rdfs:range rdf:resource="#academicStaffMember"/>
<rdfs:subPropertyOf rdf:resource="#involves"/>
</owl:ObjectProperty>
<owl:ObjectProperty rdf:ID="teaches">
<rdfs:range rdf:resource="#course"/>
<rdfs:domain rdf:resource="#academicStaffMember"/>
<owl:inverseOf rdf:resource="#isTaughtBy"/>
</owl:ObjectProperty>
<owl:Class rdf:about="#firstYearCourse">
<rdfs:subClassOf>
<owl:Restriction>
<owl:onProperty rdf:resource="#isTaughtBy"/>
<owl:allValuesFrom rdf:resource="#Professor"/>
</owl:Restriction>
</rdfs:subClassOf>
</owl:Class>
<owl:Class rdf:about="#course">
<rdfs:subClassOf>
<owl:Restriction>
<owl:onProperty rdf:resource="#isTaughtBy"/>
<owl:minCardinality
rdf:datatype="&xsd;nonNegativeInteger">1</owl:minCardinality>
</owl:Restriction>
</rdfs:subClassOf>
</owl:Class>
<owl:Class rdf:ID="peopleAtUni">
<owl:unionOf rdf:parseType="Collection">
<owl:Class rdf:about="#staffMember"/>
<owl:Class rdf:about="#student"/>
</owl:unionOf>
</owl:Class>
Some instances
<academicStaffMember rdf:ID="949352">
<uni:age rdf:datatype="&xsd;integer">39<uni:age>
</academicStaffMember>
<course rdf:about="CIT1111">
<isTaughtBy rdf:resource="949318"/>
<isTaughtBy rdf:resource="949352"/>
</course>
how can i index this faculty.owl using lucene.Also please provide any
literature or papers related to semantic document indexing and searching using
lucene if know some.Any type of help is appreciated.
Best regards,
Rahul
