摘要： 对当前互联网的搜索引擎中无法准确、高效地返回用户真正所需的数据信息等缺点进行分析，利用本体构建领域知识库和本体推理机等方法，设计实现了一个基于本体的领域知识检索系统模型。用户通过对用户本体的选择，可得到相关的目标本体，继续对其追踪，通过本体推理，搜索引擎能准确地搜索到用户所关心的本领域内的相关知识。讨论了该系统结构中各个模块的功能和该系统的特点。

Abstract: This paper analyzes the advantages and disadvantages of the current Internet search engine. Using ontology to create the domain knowledge, ontology based reasoner, etc, it designs and realizes the model of the ontology based domain knowledge search system. Through the choice of client’s ontology, clients can get the related aim ontology. If the client wants to know more about the knowledge, he will get the search results which are exactly related with the domain knowledge by the reasoner and search engine. It discusses the function of every module and the characteristic of the system.

Key words: ontology, intelligent search, domain knowledge, reasoner
