摘　　要：通过对检索资源及用户检索提问的语义解析,采用基于概念图匹配的语句相似度计算方法,不仅可得到与检索条件精确匹配的信息资源,而且还能查询到与检索条件语义相关的隐含信息资源,提高信息查全率和查准率。最后,用一个语义检索实验系统验证系统分析与设计的可行性和有效性。Through semantic analysis on the retrieved resources and the user＇s inquiry sentences,this paper uses the method of concept graphs matching to measure the similarity between the retrieved resources and the user＇ s inquiry. Thus, the information is matched precisely and the implicit information which is semantic relative to the user＇s inquiry are both retrieved. This helps to improve the recall and precision of information searching. On basis of the above work, a trial semantic retrieval system is developed to verify the feasibility and efficiency of the designed proposal for semantic rtetrieval.
