摘 要: 本文通过构建和分析国外图书情报领域的三元闭环合著网络,改进已有的复杂网络演化模型,提出严格三元闭环概念和扩张系数用以研究影响合著网络扩张速度的关键因素。研究表明,学者合著集群的扩张速度,与他跟集群成员合著的均匀程度成正相关关系。扩张系数是对目前合著网络测度指标的一个有效补充。 The concepts of Strictly Triadic Closure and Expanding Coefficient were proposed in the research of Coauthership network expansion,based on the analysis of current Library & information science Coauthership network and an optimized evolution model of Complex Network. It is proven that the expansion of a scholar’ s coauthorship clique is positively correlated with the homogeneous degree of his/her coauthoring with other scholars. Expanding Coefficient is considered as a useful supplementary index to the evaluation of Coauthorship network.
