摘要
现有搜索引擎系统在响应用户搜索请求的过程中,往往根据分词后的查询关键词在文档中出现的次数来匹配文档内容,这种仅仅根据词频来确定关键词和文档之间相关度的方法往往缺乏一定的准确性,常常导致搜索引擎的网页结果列表并不是用户真正想要的内容,这给用户的检索过程带来极大不便,也是搜索引擎"查准率"得不到彻底改善的主要原因。该文通过构建对象语义库来存储和管理各种对象集,从而实现用户基于对象的检索过程,以提高搜索引擎查询的准确率。
Search engines in popular use can offer useful information to searchers. But, in mostly searching process, users still have problems obtaining the most relevant information when processing their web queries. The result-sets returned to users from recent search engines matched the query keywords well but always away from the requested semantic. This research work presents a methodology to use object-oriented concept database to offer users' semantic search.
