基于共词分析方法的国内知识链研究热点分析

Hotspot of Knowledge Chain Research Based on the Co-words Analysis

汇总统计CNKI全文数据库中知识链领域所涉及的关键词,利用SATI 3.2软件统计这些关键词的词频,确定我国知识链研究领域使用频率最高的32个关键词。然后构造共词矩阵、相关矩阵、相异矩阵,并在此基础上利用因子分析、聚类分析和多维尺度分析三种多元统计方法对不同的矩阵进行共词分析。最后,对分析结果进行讨论,归纳国内知识链理论研究热点。

This paper collects the keywords in the researches of knowledge chain field published in CNKI full-text databases, then uses software SATI 3.1 to get the word frequency of these keywords. The top 32 highly cited keywords are identified. It constructs the co-word matrixes, correlation matrixes and discriminative matrixes. On the basis of this classification, it tries to conduct co-word analysis of different matrixes taking advantage of three multivariate statistic methods-factorial analysis, cluster analysis, and multidimensional scaling analysis. At last, it explores the current research status and hotspot of knowl- edge chain theory.
