基于Ontology的信息检索系统研究

Study of the Information Retrieval System Based on Ontology

为了减轻用户在检索信息过程中的负担,根据现有信息检索模型存在的问题,引入本体的概念,建立了一种基于本体的信息检索模型。该模型目标是根据浏览器的历史记录、用户浏览网页的浏览行为等,来更新用户兴趣模块,以不同用户的不同信息需求向用户推荐符合用户意图的信息,从而有效的提高信息检索的查全率和查准率。

In order to reduce the burden of the process of retrieving information, we have introduced the concept of ontology and established an information retrieval model based on ontology. The model objective is updating the user interest module depending on the browsing history and the browsing behavior of the users and recommending information resources based on the different information needs of different users in order to effectively improve the recall rate and the precision rate of informationg retrieval.
