1 Wiktionary LOD SIG-SWO Transformation of Japanese Wiktionary to Linked Open Data ( ), 2 1 Fujitsu Laboratories Ltd. 2 Fujitsu Ltd. Abstract: It requires a larger dictionary to make an application to interact more naturally with the users. Japanese WordNet is one of the free dictionaries, which includes thesaurus. It has RDF formed dataset that links to other resouces such as DBpedia, so it is useful for our supposing application. However the WordNet is insufficient because of the small volume of vacabulary, lack of parts of speech and derivative relations, and so on. Japanese Wiktionary, which is another free dictionary, has the parts of speech and the derivative relations. We have built a glammar ontology based on the structure of the Wiktionary to express of missing informations in the WordNet ontology. In this article, we combined the Wiktionary with the WordNet and Japanese DBpedia. The combined data is used as one unified Japanese machine readable dictionary. And from the point of the view of Japanese DBpedia, DBpedia is searchable using gramatical elements such as synonymous words. The number of the links between the Wiktionary and WordNet is 13, 620 and the number between the Wiktionary and DBpedia is 9, 654. The dataset is published using LOD4ALL WordNet[1] Wiktionary WordNet RDF(Resource Description Framework) DBpedia RDF, Web :( ) ugai@jp.fujitsu.com, Web [2].
