摘要
文章提出了一种基于本体论的Web信息检索模型,它利用领域本体知识库对用户的查询要求进行语义扩展,并且将检索到的文档在语义层次上进一步过滤,从而克服了目前的检索工具仅提供基于关键字的检索,而忽视关键字本身语义信息所造成的错检和漏检。
In this paper, an Web information retrieval model based on ontology is presented, which expands the requirement of users on semantic meaning and filters the Web pages returned by the search agent by using domain-ontology repository. It overcome the shortages of the current information retrieval tools which just offer keywords-based searching, but ignore the semantic meaning of the keywords itself.
