摘要: [目的/意义] 基于"233-1理论模型",对国外图书情报学(LIS)领域学科动态知识结构进行实证研究。[方法/过程] 以Web of Science中2006-2015年间近10年LIS领域的核心期刊文献数据为研究对象,利用时间-关键词共现分析构建时间-关键词二维矩阵,采用聚类分析、社会网络分析、时序词频统计和主题分类4种方法对时间-关键词二维矩阵进行可视化,根据gCLUTO对时间窗的划分结果,将时间窗,划分为3个阶段并结合各时间段高被引论文的关键词对LIS领域学科动态知识结构进行多维度分析。[结果/结论] 国外图书情报学领域近10年的动态知识结构呈现4种维度,即从孤立到融合、从管理到技术、从信息到知识、从理论到实践的不断嬗变。

Abstract: [Purpose/significance] This paper makes an empirical research on the domain knowledge structure of foreign LIS on the basis of theoretical model of the "233-1", in order to systematically and comprehensively analyze and present the research progress and present situation, reveal the discipline research hotspots, and explore the dynamic subject development process. [Method/process] By aking the core periodical literature data in LIS of Web of Science from 2006 to 2015 as the research object, and using the method of the time-keywords co-occurrence analysis to build a two-dimensional matrix, this paper applied the methods of clustering analysis, social network analysis, sequence word frequency statistics and subject classification to visualize matrix. According to the results of the gCLUTO, which divided time into three stages reasonably, this paper combining these results with the keywords in the highly cited papers of each stage to make a dimensional analysis of the dynamic development trend of discipline knowledge structure in LIS. [Result/conclusion] Results show that the knowledge structure of LIS in recent ten years presents the constant change from isolation to integration, from management to technology, from information to knowledge, and from theory to practice, which reveals the dynamic discipline knowledge structure in LIS in nearly a decade.

Key words: time-keywords co-occurrence analysis, social network analysis, dynamic knowledge structure, library information science
