Research of Online Education Ontology Model

Abstract

In the past twenty years, online education has grown as a main part of current education. However, the unambiguous and uniform expression of online education is a crucial challenge. Since ontology is becoming a recognized vehicle for knowledge reuse, knowledge sharing and modeling, online education(OE_Onto) is designed by using ABC model as upper ontology in order to solve these problems. OE_Onto can provide the shared knowledge in semantics to achieve the cooperation and reuse between people and the different online education systems. In this paper, OE_Onto is respectively described in five-tuple involving the concepts, relations, functions, axioms and instances. Finally, the experiment of an online education process is completed to validate OE_Onto.
