通过对国内科技文献共享平台门户系统建设现状的分析,指出在该类项目中构建通用门户的必要性。之后简要介绍通用门户产生的背景、基本概念和内容,对其中一个具有代表性的系统DNN进行详细分析,包括其基本模块和功能特色等方面的说明。最后通过湖北省科技丈献共享平台建设中的实践,具体阐述DNN在文献共享类项目的通用门户建设中的应用,从而为相关研究人员提供一些有益的借鉴。 Through the analysis of the status quo of the portal system construction of the domestic science and technology document sharing platform, it points out the necessity of building a universal portal in such projects. After that, we briefly introduce the background, basic concepts and content of the general portal, and conduct a detailed analysis of one of the representative system DNNs, including its basic modules and functional features. Finally, through the practice of sharing platform for science and technology in Hubei Province, this paper elaborates the application of DNN in the construction of universal portals for document sharing projects, so as to provide some useful references for relevant researchers.
