Currently, basic simple search techniques for curriculum are being implemented. But curriculum information retrieval applying ontology technologies is still weak level. In this paper, the curriculum of university was divided into the liberal arts and majors, and we proposed frame model by these methodes and designed management system to construct ontology. This management system was composed of ontology input system and ontology web service system. Ontology input system constructed curriculum of department into ontology by administrator and we designed web service system to retrieve curriculum by students. We validated ontology designed for curriculum using ontology tool.
