基于Ontology数字图书馆信息检索模型研究

数字图书馆的核心任务之一就是提供良好的信息检索系统,而传统的信息检索技术以关键字匹配为主,缺乏语义推理能力,对用户的查询请求没有提供语义指导,因此造成信息的误检、漏检.本文将Ontology用于数字图书馆信息检索,首先分析了数字图书馆特点和需求,接着提出了基于 Ontology 数字图书馆信息检索模型、体系结构,深入研究了关键技术,最后对研究进行了验证.

Study of Digital Library Information Retrieval Model Based on Ontology

The core task of digital library is providing good information retrieval system for the users.Traditional information retrieval technology is mainly based on keyword matching and has little semantic inferring ability.Moreover,it does not provide semantic guidance for users.So information retrieval system may miss some information of use and return some information of no use for users.Ontology is used for digital library information retrieval in this paper.At first,we analysis the feature and demand of the d...
