基于引文耦合的情报学学科结构时序分析

摘要

The study puts forward the method of bibliographic coupling strength to measure the degree of interdisciplinary. By using this method, the interdisciplinary subject structure of information science from 2004 to 2013 is analyzed. Three closest disciplines with informa-tion science from 2004 to 2013 are identified respectively:computer, economics and journalism and communication. Based on time series method, the evolution law of information science's cross-disciplinary keywords is elaborated, in addition, a visualization presentation is rendered at last.%提出利用引文耦合强度衡量学科交叉度的方法，利用该方法对2004-2013年间情报学交叉学科的学科结构进行探究，得到2004-2013年与情报学关系最为密切的三个学科，分别是：计算机学、经济学和新闻与传媒学；依据时间序列的方法说明情报学与交叉学科关键词的演化规律，并用可视化的方法呈现。
