摘要
本文从CNKI和Web of Knowledge这两个数据源分别提取国内和国外图书情报领域期刊于2001年至2012年发表论文的关键词,利用主题聚类法揭示该领域的研究热点,并重点利用新兴可视化工具NEViewer进行研究热点分析。基于研究结果从热点分布、热点演化、研究前沿、研究方法、应用领域等方面对比分析了国内外图书情报领域研究的特点及研究工作的异同。
This study obtained research data from CNKI and Web of Knowledge, extracting keywords from papers pub- lished from 2001 to 2012 in both Chinese and English LIS journals. The method of topic clustering was used to reveal the research loci in LIS, and the newly developed visualization tool NEViewer was used to analyze these foci.
