摘　　要：为了用户方便快速地进行文献检索,将本体引入文献检索,设计实现了一种基于领域本体的文献检索系统.利用本体中概念与概念之间的关系对用户的查询请求进行语义推理,全面而准确地返回查询结果.实验表明,基于本体的文献检索比传统的文献检索在查全率、查准率及语义相关率上都有较大提高.For users＇ convenient and fast literature retrieval, a literature retrieval system based on domain-ontology was designed and implemented. Using the relationship between the concept and the concept in ontology, semantic reasoning was done, and comprehensively and accurately returned search results. The recall ratio, the precision ratio and semantic related ratio of literature retrieval system using ontology were improved greatly.

关 键 词：本体 文献检索 语义推理 语义相关率
