An Ontology Based Knowledge Sharing Approach in E-learning

The problem of Knowledge sharing in E-learning has received a lot of attention in recent years. It covers the cross research area including information-integration, and ontologies etc. The paper provides a semantic integration approach to solve the knowledge sharing problem. An ontology based knowledge organization model is firstly built to improve the traditional information resources model, and then the semantic annotated knowledge resource is produced. Secondly, the ontology described resources are mediated in term of the semantic mapping results. Finally, the sharing system containing the user feedback and matching result rankings is analyzed in details
