摘　　要：随着网络的飞速发展,人们对互联网信息检索的需求不断专业化、细致化,通用搜索引擎技术在一定程度上已经不能满足用户的搜索需求。与此同时,本体相关的技术在信息检索系统的研究越来越成熟。在本体相关技术的基础上,提出一种可以提高搜索效率的垂直搜索引擎构架,并着重对构架中的关键技术及其实现进行了研究。The requirements of Internet information search become more professional and specific constantly along with the explosive growth and diversification of the Internet. The general search engines are unable to provide satisfied services to users. At the same time, the study on techniques related to ontology in information searching system is getting mature. In this paper it proposed a vertical search engine architecture on the basis of ontology-related technique which improves the searching efficiency. The key techniques in the architecture and their implementation are mainly studied.
