| Abstract: |
| Co-word analysis plays a pivotal role in the cognitive structure analysis of discipline. This paper collects a dataset of keywords from fourteen key journals of library and information science (LIS) in the Chinese Social Sciences Citation Index (CSSCI) and extracts the most frequent 100words based on the right truncation method. Based on the 100words, four major branches are identified by hierarchical clustering, and content characters in fourteen journals are analyzed by hierarchical clustering, multidimensional scaling and heat map. Furthermore, evolution trajectory and usage trends of the 100words can reveal the cognitive structure of LIS and its evolutionary process. This paper finds that the LIS in China has different concerns at different times, which have their own life-cycle. Currently, the LIS tends to treat “information” as its research core, with emphasis on technology application and management innovation. 12figs. 4tabs. 32refs. |
| 中文摘要: |
| 共词分析在学科认知结构分析中具有非常重要的作用。本文利用信息检索中的“前方一致”原则，从中国社会科学引文索引收录的14种图书情报学期刊的关键词数据集中找出100个频繁出现的词。在这100个词的基础上，利用层次聚类得到我国图书情报学的四个主要分支，利用层次聚类、多维尺度分析和热点图相结合的方法分析这14种期刊的内容特征，并研究它们的演化轨迹和使用趋势，从而揭示认知结构及其演化过程。研究发现：我国图书情报学在不同时间段有不同的关注点，它们也有着自身的生命周期，目前整个学科越来越将“信息”作为研究核心，热点偏重于技术应用与管理创新。图12。表4。参考文献32。 |
