基于语义检索模型的数字图书馆服务平台研究

Research on Digital Library Service Platform Based on Semantic Retrieval Model

为满足目前数字图书馆相应语义匹配的需求,使提供计算机可读语义信息得以有效实现,主要对数字图书馆服务平台进行了研究,在分析数字图书馆使用现状的基础上根据图书馆的具体使用情况完成了基于语义检索模型的创建,进而完成了基于语义信息检索模型的平台设计,对以检索模型为依据设计的检索系统原型进行全面分析,针对图书元数据本体通过DC元数据实现其描述的创建,使检索数字图书馆信息的效率得以显著提升,实现知识元数据提取及知识推理功能,具有较高的可行性,为数字图书馆服务平台的完善提供参考。

In order to meet the needs of the corresponding semantic matching of digital libraries,the computer-readable semantic information can be effectively realized.This paper mainly studies the digital library service platform,based on the analysis of the current use of digital libraries.The specific use case completed the creation of the semantic retrieval model,and completed the platform design based on the semantic information retrieval model.The prototype of the retrieval system based on the retrieval model was comprehensively analyzed,and the book metadata ontology was realized by DC metadata.The creation of its description makes the efficiency of retrieving digital library information significantly improved,and realizes the knowledge metadata extraction and knowledge reasoning function,which has high feasibility and provides reference for the improvement of digital library service platform.
