| Research Abstract |
Here is discussed how to build up ontologies with many properties from Japanese Wikipedia. The ontologies includes is-a relationship(rdfs : subClassOf), class-instance relationship(rdf : type) and synonym relation(skos : altLabel) moreover it includes property relations and types. Property relations are triples, property domain(rdfs : domain) and property range(rdfs : range). Property types are object(owl : ObjectProperty), data(owl : DatatypeProperty), symmetric(owl : SymmetricProperty), transitive(owl : TransitiveProperty), functional(owl : FunctionalProperty) and inverse functional(owl : InverseFunctionalProperty). Experimental case studies show us that the built Japanese Wikipedia Ontology goes better than DBpedia from utility when we use, such as Hub of Linked Data, especially in Japan.
