学科交叉研究热点聚类分析——以国内图书情报学和新闻传播学为例

Clustering Analysis on Discipline- crossing Research Hotspots:An Example of Library and Information Science and Journalism and Communication Studies

在规范化的学科关键词交集的基础之上,从定量角度引入系统聚类分析和战略坐标分析方法,结合聚类类团命名的粘合力指标,绘制出高频交叉关键词的聚类树状图和战略坐标图,深入探讨学科交叉研究热点的内在联系和发展脉络。研究得出有关图书情报学和新闻传播学两门学科交叉研究热点领域的主题划分、结构特性和演化过程的一些有益结论。

This paper constructs normalized keyword intersection of two disciplines from core periodicals and then obtains high -frequency intersecting keywords and their co-word matrix. Based on that, the paper uses keywords analysis and social network analysis to discuss the overall characteristics, subject construction, internal relations and evolution of crossing research hotspots of two disciplines. Taking the two disciplines of Library and Information Science and Journalism and Communication Studies as examples, the paper verifies the feasibility of the idea and gets some useful conclusions.
