基于知识图谱的情报学学科发展研究

The Research on the Discipline Development of Information Science Based on Knowledge Map

应用CiteSpaceⅡ,对SSCI收录的1999—2011年的5种核心期刊所发表的4064篇情报学文献进行了分析。通过绘制研究机构知识图谱,对情报学研究机构进行了分析,发现美国、英国和中国的情报学研究最为突出;通过绘制引文知识图谱,确定了中介中心性高的文献,把情报学学科发展研究分为3个阶段进行,分析了各个阶段研究主题的变化。

By using CiteSpaceⅡ,this paper analyzes 4 064 research papers on information science published by 5 kinds of core journals in the period of 1999-2011 and collected in SSCI.Through drawing the knowledge map of the research institutions,this paper finds that the greatest contributions in the study on information science have made by the United States,the United Kingdom and China;and though drawing citation knowledge map,determines the papers containing the highest value of betweenness centrality,and divides the research of discipline development of information science into three stages,and analyzes the changes of research subjects in each stage.
