摘　　要：讲述了目前检索系统存在的不足以及产生这些不足的原因,介绍了本体的概念及其在语义检索领域中的作用。在此基础上提出了一种基于知识库的语义检索系统模型,并对该模型的实现原理和关键技术进行了详细的阐述。实验结果表明,相对于传统的方法,该方法能大幅提高用户检索的查全率和查准率。First of all,this paper describes the deficiencies of the current system ,as well as the reasons for these deficiencies. And then the concept of ontology and its role in the field of semantic retrieval were introduced.On this basis,a semantic retrieval system ,based on knowledge base ,was proposed,and in which the implementation principle and key techiques were described in detail. Finally,the experimental results show that the method can greatly enhance user retrieval precision and recall rate compared to traditional methods.
