To enhance the retrieval accuracy of information search engine, this paper proposes an information retrieval system based on Ontology and document refinement, which is realized by employing the semantic description and relevance of Ontology to the system. It describes the using of LSI to replace the traditional VSM  in the results of sorting process. Using a comparative experiment, the authors show the new approach is more feasible and effective than VSM, which can improve the performance upto 10.55%-17.63%.
