This paper mixed ontology to the traditional information retrieval to realize quickly and accurately search information. The results proved that base on the semantic Web of ontology semantic information retrieval was more accurate, narrowed the searching scope and cut down the redundancy. Simulation experiment showed that semantic information retrieval base on ontology had a good shielding effect.%提出将Ontology融合到信息检索技术中,实现快速、准确的信息检索.实践证明,建立在语义web基础上的Ontology语义检索技术,比传统的检索提高了检索的准确率,缩小了搜索范围和减少冗余.通过仿真实验表明:基于本体库的语义信息检索效果良好.
