Wikipedia Category Ontology - Utilization of Wikipedia category from the view point of knowledge engineers -

Abstract

Wikipedia is one of the largest knowledge resources available via the Internet. Several methods have been proposed for extracting knowledge/information from Wikipedia, but methods based on extracting knowledge from the Wikipedia category structure can not utilize whole part of its structure because of the complexity of the relationships between the various categories. In this paper, we briefly review our previous researches on analyzing Wikipedia category and introduce a framework called "Wikipedia Category Ontology" (WCO) that aims to act as a basis for interpreting the Wikipedia category structure. It is based on a classification of category types and relationship types and available online in the form of Linked Open Data at http://wcontology.org/. We also demonstrate the system by using Wikipedia category analysis scenarios.
