Research on the Construction of Digital Library Platform in the Age of Digital Economy
Abstract The digital library has to retrieve in the mass information what the users need to provide users with more and higher quality resources. In this paper the author analyzes the information resources and hierarchical query model of the digital library platform, introduces grid technology, explains the specific advantages and service connotation of the digital library, and analyzes the degree of realizing the hierarchical service of the digital library to meet the actual needs of users. In view of the problems of low data processing ability, lack of resources and content, and lack of interaction in the digital library, this paper puts forward a series of strategies to optimize the service ability of the digital library's hierarchical retrieval platform, so as to provide users with accurate and all-round personalized information that can meet their query semantics and provide users with satisfactory services.
Key words digital library; information resources integration; hierarchical query; user service
1 引言
在數字经济时代,数字图书馆将分散分布、孤岛式存储的数字资源整合为一个完整的“大数据”,但在这个过程中,存在数据来源多元化、数据存储方式多样化、数据形式非结构性等问题[1-4],在服务能力和竞争能力方面走出一条新路至关重要,因此该领域学者纷纷投入到数字图书馆平台检索研究中。
童忠勇[5]基于公共图书馆数字信息资源构建、互联网技术与国家有关政策,描述了数字图书馆资源平台构建整体思路,同时根据图书馆工程与推广工程的构建成果,通过云计算和大数据等一系列技术描绘出了平台总结构与核心功能模块,设计并构建了基于各个省市图书馆所具优势、面向大众和共享开放的图书馆资源服务平台;常飞[6]指出云计算和云资源的共享模式能够为数字图书馆平台构建奠定技术基础。混合云服务是适合应用至……
