基于本体的构件库智能检索方法研究

摘要

基于本体的语义检索是建立在语义网基础上的检索技术,它能提高检索的查全率和查准率.本文结合本体对构件库的检索进行研究,给出了基于本体的构件库检索框架以及检索流程,讨论了需求、规则的相关概念及其性质以及需求/规则的映射方法.在规则推理的讨论中,引入了匹配度和优先级算子的概念,并对匹配度进行了扩展,使检索结果能够进行全局排序.%Semantic retrieval is based on ontology and is a retrieval strategy for semantic web.The semantic retrieval results in the improvement in the precision and completeness.This paper focuses on the research method of intelligent retrieval of component repository.The framework and process of retrieval of component repository based on ontology is brought forward,and the concept and principles of requirement and rule,the method ofthe mapping between requirements and rules are discussed in this Paper.In the discussion of rule reasoning,the concept of match degree and priority algorithm operator is brought forward.The match degree is extended in order to make the search results sorted in complete order.
