| Abstract: | Domain ontology provides a rich set of concepts for shared knowledge,and it is the base of sharing domain knowledge.This paper discusses the methods of organization and ontology representation of the curriculum knowledge system,constructs the knowledge discovery models based on domain ontology,expounds the mapping process between two ontology based on the similarity of domain concept couples.It realizes the flexible share of teaching resource based on the unit of knowledge. |
