摘 要: 知识图谱可以以可视化的形式展现学科的知识体系,借助教育技术期刊载文中的作者合著信息,可以构建出我国教育技术学者合著网络知识图谱;通过社会网络分析方法,可以对合著网络进行整体属性、社群结构、中心性、小团体、核心—边缘结构分析,从而得出合著网络的各项特征。结果显示,我国教育技术学者合著网络的密度较小,网络聚集度不大,虽具有小世界效应特征,但连通性较差,合著局限在小圈子内,同时具有核心—边缘结构。可划分为15个合著群体,有较多的高产合著组合和合著小团体,内部派系比较复杂,不过规模都较小,他们信息分享和科研合作机会的差别较大,黄荣怀、何克抗、李克东等学者是合著网络的核心学者。 Mapping knowledge domain displays knowledge by the techniques of visualization.After a review of articles related to the coauthors' information in 8 Chinese educational technology academic journals,mapping knowledge domain on Chinese educational technology scholars' coauthor network is constructed.With social network analysis method,the coauthor network's characters,social structure,centrality,subgroups and core-edge structure are analyzed before various features of coauthor network are concluded.The results show that coauthor network,with low density and aggregation degree,the features of small-world network,weak connectivity,coauthored only in a small group,core/edge structure,can be subdivided into 15 coauthor groups. There are some high-yield coauthor groups and coauthor subgroups with complicated interrelationship and small scale,whose chances for information sharing and research cooperation differ from each other.Hang Ronghuai,He Kekang,Li Kedong and other 6 scholars are the core scholars in the coauthor network.
