基于SNA的我国图书情报学研究机构合作情况分析

The Cooperation of Research Institutions of Chinese Library and Information Science Based on SNA

利用社会网络分析方法,对2001-2010年图书情报学主要期刊发表论文的相关信息进行统计分析,并可视化其网络关系,分析图书情报学研究机构的分布与合作情况。首先,统计研究机构的发文数量,找出重点研究单位;其次,构造合作矩阵,绘制合作网络图,设定阈值,分析研究机构的合作现状;再次,对研究单位以及其发表文章的关键词构造2-模矩阵,绘制2-模数据网络图,划定阈值,找出研究机构的重要研究领域和重点研究领域的主要研究单位。

This paper collects papers published in the major core journals in the field of library and information science from 2001 to 2010,and investigates the cooperation and distribution of research institutions by using the social network analysis method.Firstly,according to the statistical analysis of the number of papers published by research institutions,the paper identifies the most important scientific research units.Secondly,the paper constructs a cooperation matrix,draws cooperation network,sets the threshold,and then explores the current situation of cooperation among research institutions.Thirdly,the paper constructs a 2-mode matrix about the research units and the keywords of their papers,draws 2-mode network,sets the threshold,and then identifies the main research fields of the research institutions and the main research units of the key scientific subjects.
