【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g CLUTO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]:[objective / significance] based on the 233-1 theoretical model, this paper makes an empirical study on the dynamic knowledge structure of foreign library and information science (Lis) domain. [methods / process] taking the core periodical literature data of LIS from 2006 to 2015 in Web of Science as the research object, using time-keyword co-occurrence analysis to construct the two-dimensional matrix of time-keyword, cluster analysis and social network analysis were used. Temporal word frequency statistics and topic classification are used to visualize the time-keyword two-dimensional matrix. According to the result of g CLUTO to divide the time window, the time window, The dynamic knowledge structure of LIS domain is analyzed in three stages and with the key words of high citation papers in each time period. [results / conclusion] the dynamic knowledge structure in the field of library and information science abroad in recent 10 years presents four dimensions: from isolation to integration, from management to technology, from information to knowledge, from theory to practice.
