Construction of Japanese Wikipedia Ontology

Abstract

Wikipedia is a largest online encyclopedia that covers varieties of topics using struc- tured documents (e.g., infobox for describing metadata, and classication using Wikipedia cate- gory). There are several efforts to extract structured knowledge, such as DBpedia, YAGO2, and Japanese Wikipedia ontology. However, it was not used in consideration of the characteristics of the Wikipedia category. So far, we have analyzed and organized the Wikipedia category. In this study, We make a Japanese Wikipedia ontology from the rearranged Wikipedia categories, in publishing as LinkedOpenData, we will report what we have defined and consider future use.
