The Application of Ontology Model in Intelligent Tutoring System

Intelligent tutoring system (ITS) is a new educational methodology. It includes the integration of education technology and advanced technology in multidisciplinary field. In this paper, we focused on the intelligent knowledge tutor mode which is based on the theory of ontology, an architecture of integrated intelligent tutoring system (IITS) is proposed, its ontology model is established, and its application characteristics is analyzed. Research shows that multi-level isomeric knowledge integration processing can be excluded the factors generated internal interfere and conflicts from the bottom of system, large isomeric information could be better shared and reused, which solved the problem of processing the personify and visualization with IITS knowledge; the redundancy feedback control based on the ontology model can achieve self-learning, self-regulating and self-maintenance of the knowledge for settling the distributed adaptive of the IITS knowledge processing.
