以CNKI收录的LIS博硕论文为基础数据,将2000-2015年平均分为四个时间段,基于聚类分析,利用Mindmapper绘制主题演变图,分析研究主题的持续、转移及弱化情况,继而利用战略坐标图,探讨LIS的主题演变的成熟度及核心度情况。LIS的持续研究主题主要集中在图书馆服务、信息服务与知识服务、文献计量与知识图谱、层次分析法等方面,并随着时间发展,出现新兴研究主题。本文系统梳理国内LIS发展的主题脉络,以期为LIS的研究及学科发展提供借鉴与参考,促进LIS的可持续发展。
Based on the LIS Bo Shuo theses collected by CNKI, the paper divides the average of 2000 to 2015 into four time periods. Based on the cluster analysis, the paper uses Mindmapper to draw the thematic evolution diagram and analyzes the persistence, shifting and weakening of the research topics, Strategic map to discuss the maturity and core of LIS’s thematic evolution. LIS research topics continue to focus on library services, information services and knowledge services, literature measurement and knowledge maps, analytic hierarchy process, etc., and with the development of time, emerging research themes. This paper systematically sorts out the theme of LIS development in China, with a view to providing reference and reference for the research and subject development of LIS so as to promote the sustainable development of LIS.
