Introduction We have proposed learning methods for building a large-scale and high accuracy general ontology called Japanese Wikipedia Ontology (JWO) by extracting the concepts and relationships between concepts from various semistructured resources in Japanese Wikipedia [3]. However, JWO has problems because it lacks upper classes and appropriate definitions of properties. Thus, the aim of our research was to complement the upper classes in JWO by aligning JWO and Japanese WordNet (JWN) 3 using ontology alignment(OA) techniques. To achieve our aim, we developed tools that help users to refine classinstance relationships, to identify the JWO classes that need to be aligned with JWN synsets, and to align the JWO classes with the JWN synsets via user interaction. We also integrated JWO and JWN by using a domain ontology development environment, DODDLE-OWL [1]. Moreover, we propose a method for building a class hierarchy with defined properties by elevating common properties defined in sibling classes to higher classes in JWO. This research is based on our previous study [2]. The refined JWO and source code of the developed tools can be downloaded via a GitHub repository .
