摘　　要：针对搜索引擎查找准确率低、检索效果差的问题,提出了基于本体的搜索引擎.该搜索引擎首先构建相关主题本体知识库,再利用网络爬虫下载网页内容和网页结构特征,并对内容进行智能识别,找出与本体相关内容识别为相关本体,通过与本体知识库内容对比,筛选特定的统一资源定位器(URL)地址及与计算机网络安全相关的本体,从而发现计算机网络安全相关信息,同时建立不同服务提供者之间的关联关系及服务提供者之间的层级关系,最后将抽取出的计算机网络安全信息存储到以本体为模型创建的数据库中,并成为用户搜索服务的最终数据来源.实验结果表明,本体可提高搜索引擎的查准率,减少冗余信息,从而提高查询精度.Aiming at the problems of low search accuracy and poor retrieval effect,an ontology-based search engine was proposed,which firstly constructs topic-related ontological knowledge base,and then uses the web crawler to download web content and structural features of web pages,and intelligently recognizes the content so as to find out and recognize the ontology-related content.By comparing with the content of ontological knowledge base,the paper screens specific uniform resource locator（URL）address and the ontology that is related to computer network security,in order to find the relevant information and at the same time establish the associative and hierarchical relationship between different service providers.Finally,the computer network security information is stored in the database modeled on ontology,and becomes the final data source of the user search service.The experimental data shows that the ontology can improve the accuracy of the search engines,reduce redundant information and improve the query precision of search engines.
