摘　　要：针对基于关键字的传统查询方法存在的不足,提出一种面向语义查询的信息检索模型.该模型将信息检索方法与语义Web技术相结合,通过基于本体的知识库实现用户对文档库的语义查询;同时,综合考虑语义检索和关键字检索两种情况,提出一种相似度计算方法,有效地满足了用户对Web信息资源的要求,并为以后的语义检索研究奠定了理论基础.Aimed. at the weakness of the keyword -- based search, an ontology--based information retrieval model was presented. This model is combined the information retrieval approach with semantic web technology and, on the basis of ontology--based knowledge base, achieved some semantic query to file repositories. Meanwhile, comprehensively considering both semantic and keyword--based search, a similarity measuring algorithm was proposed, so that the system could effectively meet the requirements of information searching of users and laid a theoretical basis for the research on the semantic search.
