摘要
主题词和关键词是共词聚类分析法中最常用的分析对象,但在相同的条件下,两者是否有相近的聚类效果?针对同一文献标本,采用同样的常规处理过程,对关键词和主题词的聚类效果进行对比统计分析,结果显示在高频词、类团成员及聚类质量上,存在较大差别。表明在共词聚类分析法的具体应用中,选择不同的对象时,不能简单套用相同的数据处理过程。最后,就共词聚类分析法的应用、处理规范等方面提出一些意见和建议。
Subject headings and keywords are the objects in co-word cluster analysis. The comparative analysis is done between subject headings and keywords in the same document samples and the same treatment process. The results show that differences are exist in high frequency words,cluster members and cluster quality. Co-word cluster analysis should make a difference standard between subject headings and keywords. At last, this paper gives some suggestions about co-word analysis on the application, management standards and so on.
