ONTOMO: Development of Ontology Building Service: Evaluation of Instance Recommendation Using Proper Noun Extraction

摘要

In the research area of web technologies, ontologies are recently widely used. By using ontologies, we can share common understanding of the structure of information among people or software agents and enable reuse of domain knowledge. However, the difficulties in building ontologies have been pointed out and its costs are raising problems currently. To build an ontology, we must determine the domain that the ontology will cover, and define taxonomy, properties, instances of the ontology. It is very difficult and time consuming to build them without any tools. In this paper, we propose ONTOMO that enables Internet users to take part in building ontologies as a part of collective intelligence. In particular, we present an instance recommendation mechanism based on the editing history of multiple users together with experimental evaluations.
