Ontology Based Approach for Retrieval Intention Analysis in e-Learning System

摘要：

Knowledge management and retrieval are important parts of an e-Learning system. The retrieval intention is hard to express by traditional keywords based retrieval mode. In this paper, based on analyzing keywords in semantic layer, semantic similarity is calculated to catch the users retrieval intention. Finally, the proper semantic mapping from keywords to concepts in knowledge base is realized. The semantic retrieval approach in this paper is significant for the individualized e-Learning system construction.
