A Proposal of Ontology Refinement System using Similarity among Is-a Hierarchies

Abstract

Quality of ontology is important because it is connected directly with the performance of an application system using the ontology. However ontology refinement to improve its quality needs knowledge and experiments in ontology development. Therefore, ontology refinement task is too difficult especially for beginners in ontology building. In order to solve this problem this article proposes an ontology refinement support system based on similarity among is-a hierarchies and an evaluation of it. The system can support content refinements for ontologies.
