Wikipedia has been recently drawing attention as a semistruc-tured information resource for the automatic construction of ontology. We proposed a method of constructing a general-purpose ontology by automatically extracting the is-a relations (rdfs:subClassOf), class-instance relations (rdf:type), property relations and types. Methods to automatically construct ontologies with numerous property relations and types from Wikipedia are discussed here. The ontologies include is-a relations, class-instance relations and property relations and types. The property relations are triples, property domain (rdfs:domain), property range (rdfs:range), and property hypernymy-hyponymy relations (rdfs:su bPropertyOf). The property types are object (owl:ObjectProperty), data (owl:DatatypeProperty), symmetric (owl:SymmetricProperty), transitive (owl:TransitiveProperty), functional (owl:FunctionalProperty), and inverse functional (owl:InverseFunctionalProperty).
