摘要
作为一种有效表现概念层次结构和语义的理论和方法 ,Ontology被广泛应用于计算机科学和信息管理领域。本文针对当前网络资源检索中存在的查准率和查全率低、检索返回结果过多等问题 ,提出基于Ontology的概念检索。文中介绍了Ontology在概念检索中的作用 ,分析了Ontobroker———概念代理引擎 。
As an effective theory and method used to express the hierarchy and semantic meaning of concepts,ontology is extensively applied to many fields in computer science and information management.According to the problems of rather limited precision and recall and too many feedback results in Web resources retrieval,this paper proposes an ontology based concept retrieval method.The paper describes the effect of ontology in concept retrieval,analyzes Ontobroker—a concept agent engine,and explores the applications and development of ontology in Web information concept retrieval.
