摘要：To overcome shortcomings that semantic association in traditional model is just dependent on words instead of their relationships, the concept retrieval model based on Description Logic is introduced in the paper, and Extend reasoning algorithm is proposed. And then on the basis of previous work, a concept retrieval System based on Description Logic is implemented. The experimentation comes to the conclusion that the system based on Description Logic implements effective reasoning on knowledge base and navigation for users, and performs better than the traditional retrieval system both on recall and precision.
