论文部分内容阅读
本文选取CNKI数据库收录的3390篇有关数字图书馆的相关研究的论文为数据源,利用BICOMB进行相关数据提取。首先是对研究文献进行形式特征的可视化分析,包括研究文献的时间分布、著者及著者机构分布、来源分布。然后对研究文献的内容特征进行可视化分析,通过高频关键词的统计分析、共词分析等分析了近年来数字图书馆有关研究的热点领域。发现我国数字图书馆研究论文年发文量和研究主题随时间的推移而变化显著。从数量上看,发文量依次经历了上升、下降、基本持平3个阶段,从内容上看,以资源建设、信息技术、知识服务等主题相互结合、渗透的线索发展。
This paper selects 3390 articles from the CNKI database related to digital library as the data source and uses BICOMB to extract relevant data. The first is the visual analysis of the formal characteristics of the research literature, including the time distribution of research literature, the distribution of author and author institutions, and the source distribution. Then, the content characteristics of the research literature are visualized. The hot spots of digital library research in recent years are analyzed through the statistical analysis of high-frequency keywords and the analysis of common words. Found that the annual volume of research papers and research topics of digital library in our country changed significantly with the passage of time. In terms of quantity, the number of sentinels went through three stages: rising and falling in turn. From the content point of view, the development of clues such as resource construction, information technology and knowledge service combined with each other.
