基于关键词交集的学科交叉研究热点分析——以图书情报学和新闻传播学为例

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

构造了两门学科核心期刊论文规范化的关键词交集,从关键词交集中获取两门学科的高频交叉关键词及其共词矩阵,在此基础上通过关键词词频分析和社会网络分析探讨两门学科交叉研究热点领域的整体特征。并以图书情报学和新闻传播学为具体研究对象进行实验,得出有关期刊管理与评价、知识产权、企业知识管理等领域是两门学科在研究时段内最为关切的交叉研究领域等有益结论,从而验证了上述构想的可行性。

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 example, the paper verifies the feasibility of the idea and gets some useful conclusions.
