国际图书情报领域作者、机构和国家合著网络剖析

借助SPSS软件从2015年JCR收录的图书情报学领域的86种核心期刊中，随机选取20种期刊作为数据来源，利用书目共现分析系统——BICOMB软件生成共现矩阵，运用UCINET和Pajek软件实现作者、机构和国家3个合著网络的可视化，分析各合著网络的聚类系数、平均距离、高频合作群体，检验小世界特性，揭示网络整体结构、核心学术群体和高频合著集团之间的关系。结果表明国际图书情报领域发文量、合著率及合著规模基本逐年上涨，合作科研已成为不可逆转的大趋势，3个合著网络均具聚类系数大，平均距离短的特点，符合复杂网络的小世界理论，说明国际图书情报领域整体合著网络具有较高的连通性、内部交流频繁、信息传递畅通。高频合著作者和高频合作机构有着确定的研究方向，且倾向于将其连续性的科研成果发表于同一期刊。

Cooperation Network Analysis of Authors,Institutions and Countries in the Field of International Library and Information Science

In this paper,it randomly selected 20 out of 86 kinds of JCR journals in library and information science fieldthrough SPSS software as the data source,generated the author co-occurrence matrix through bibliographic items co-occurrence matrix builder BICOMB,mapped the co-authorship networks of authors,institutions and countries through UCINET software,analyzed the three co-authorship networks' clustering coefficient,the average distance,high frequency cooperationgroup,tested the small world characteristics,revealed the structure characteristicof the overall network,the relationship between the core academic group and the high frequency co-authorshipgroup.The results showed that the publishing quantity,the rate of cooperation papers and the scope of cooperationof the field of library and information science was increasing year by year,cooperative research had become an irreversible trend and the three co-authorship networks with characteristics of high clustering coefficient and short average distance,in line with the small world theory of complex network.It showed that the cooperation network of international library and information was highly connected,internal communication was frequent,and the information was communicated smoothly.High frequency cooperative institutions usually had certain research direction,and tended to publish their research results in the same journal.
