近十年来《情报科学》作者合作可视化分析

Visual Analysis on Author Cooperation of Information Science in Recent Ten Years

基于社会网络分析、组元分析、因子分析、关键词频次分析对知网(CNKI)期刊数据库中2006至2015年《情报科学》中的3895篇文章的作者合作进行了分析。分析了整个合作网络的度、聚集系数、距离、直径、密度等指标,通过度分布探究了合作网络的结构特征,通过中心性分析探究了节点的影响力及网络的中心化程度。通过组元分析、因子分析、关键词词频分析对重要的合作团体的构成、研究热点等进行了探究。结果表明十年间合作网络中作者数量、合作次数不断升高,最终形成了一定规模的合作网络。合作研究热点集中在信息检索、信息资源评价、信息资源管理、信息生态、知识管理、知识共享、知识网络、数字图书馆技术、竞争情报、信息产业等领域。

This paper analyzed the network of author cooperation of 3895 articles ofInformation Sciencefrom CNKI jour-nals database from 2006 to 2015 based on social network analysis, component analysis, factor analysis and keyword fre-quency analysis. Firstly degree, clustering coefficient, distance, diameter, density and other indexes were analyzed, The au-thor searched for the structure characteristics of network through the degree distribution, searched for the influences ofnodes and the centralization of network through the centrality analysis, then searched for the structure through the compo-nent analysis, factor analysis and keyword frequency analysis.The auther also researched hotspots of the important coopera-tion group. The results showed that in the recent ten years the number of the author and the cooperation of the network rosesteadily, eventually formed a certain scale cooperation network, and the hotspots were focused on information retrieval, in-formation resource evaluation, information resource management, information ecology, knowledge management, knowledgesharing, knowledge network, digital library technology, competitive intelligence, information industry.
