摘要： 根据概念及概念之间的语义，提出一种多相关本体的模糊信息检索模型，用本体的关系表示模糊关系。描述本体信息检索模型的处理过程及检索机制，讨论应用不同类型本体的检索效果和影响，并采用TREC的评价方法评估该模型。结果证明该模型具有较好的整体性能比，能改善用户需要的检索结果。

Abstract: For the semantics between the concepts, this paper presents a fuzzy information retrieval model of multiple related ontologies whose relationships are expressed as fuzzy relations. The process and retrieval mechanism of ontology information retrieval model are illustrated, the effect and influence of applying different types ontology are discussed, and the system following the evaluation method of TREC is estimated. Experimental results prove that the proposed model presents better overall performance and is an natural way to improve retrieval results of users needed.

Key words: multiple related ontologies, information retrieval, fuzzy relation
