Development of ontology building service ONTOMO: Evaluation of ontology recommendation agent using proper noun extraction

Abstract

Ontology-enabled services are rapidly increasing in the Web. However, those are sort of "lighter" ontologies compared with ontologies used in design and diagnosis. In this paper, we propose ONTOMO that enables internet users to take part in building those ontologies. ONTOMO is designed not for ontology experts, but for general users of the light-weight ontology. So we focused on easy-use, no installation, and cooperative work environment. Also, it has an agent function which recommends instances and properties belong to ontology classes to boost the users' input. In the recommendation agent, we built our own proper noun extraction mechanism based on bootstrapping. Furthermore, ONTOMO provides a ontology-based blog search as a sample application to motivate the users' ontology building. After the ONTOMO overview, we present the instance and property recommendation agent with experimental evaluation.
