摘　　要：在网络技术不断发展的过程中,数字图书馆也已经成为了人们获取信息和传播信息的主要途径。但是现代数字图书馆缺少相应的语义匹配,所以无法实现计算机可读语义信息的提供。基于此,为了能够实现数字图书馆信息的有效检索,并且促进知识元数据的本体化、提取及知识推理,就设计基于语义的数字图书馆信息检索模型。首先,对数字图书馆的具体使用进行全面分析,创建基于语义的数字图书馆检索模型,并且设计检索系统原型,之后对其进行全面分析,通过DC元数据创建图书元数据本体的描述,根据图书馆的具体使用创建基于语义的数字图书馆检索模型。根据设计的检索模型设计系统原型,利用实验对比进行分析,表示创建的检索模型具有实用性和可行性。In the process of the continuous development of network technology,digital library has become the main way for people to obtain information and disseminate information.However,the modern digital library lacks the corresponding semantic matching,so it cannot provide the computer readable semantic information.Based on this,in order to be able to achieve the efficiency searching of the information of the digital library,and promote the metadata of ontology,extraction and knowledge reasoning,will design the digital library information retrieval model based on semantic.First of all,the specific use to conduct a comprehensive analysis of the digital library,create a model of digital library retrieval based on semantic,and circular design retrieval system,then carries on the comprehensive analysis,create book metadata ontology through DC metadata description,according to the specific use of library to create a model of digital library retrieval based on semantic.Based on the design of the design system prototype,the experimental comparison is carried out to show that the retrieval model is practicable and feasible.
