Application Research of Ontology in E-Learning Environment

In this paper, awareness and situation ontology model is presented to process awareness and learning situations in E-Learning environment. By this model, knowledge domain, awareness information and learning situations can be described reasonably and efficiently. In addition, reasoning rules for awareness and situation are given in this model. According to these reasoning rules, the learnerpsilas awareness information and learning situations can be concluded. We design and realize an E-Learning system based on this ontology model. The experiment results show that learner´s learning efficiency is raised greatly after awareness and situation ontology model is adopted.
