摘要
[目的/意义]通过合作网络的演化研究,揭示我国图情领域合作研究的发展历程并发现其中的规律,预测合作网络的发展方向,以期能够促进该领域的发展,为未来学者合作提供借鉴。[方法/过程]以CSSCI论文为数据源,构建有向加权的学者合作网络模型,运用社会网络分析法,分年段进行凝聚子群、块模型以及优先连接分析,进而研究网络结构的发展、合作模式的演变以及网络的扩张规律。[结果/结论]研究表明我国图情领域的学者合作在前期处于发展阶段,在后期出现“聚合—分散—聚合—分散”的循环现象;等级合作模式贯穿于图情学科发展的总过程,凝聚子群合作模式逐渐被淘汰,未来的合作网络将会以等级模式、中心模式、中心—边缘模式为主;网络符合幂律分布,并根据网络扩张规律提出了有向网络中的优先连接模型。
[Purpose/significance]Through the research on the development and evolution of the co-authorship networks,it reveals the development process of scholars’cooperation in the field of library and information science in china and discovers the cooperative laws in it,and predicts the development of the future co-authorship networks,in order to promote the development of this field and provide reference for future scholars’cooperation.[Method/process]Using CSSCI papers as the data source,we construct a directed weighted co-authorship networks model.Using the social network analysis,the analysis of cohesive subgroups,block models,and priority connections is carried out by years,and then the development of network structure,the evolution of cooperation modes and the law of network expansion are studied.[Result/conclusion]Research shows that the co-authorship networks in the library and information science is in the development stage in the early stage,and the cycle of“aggregation-dispersion-aggregation”appears in the later stage.The hierarchical cooperation model runs through the overall development process.The cohesive subgroup cooperation model is gradually eliminated.The future cooperation network will be based on the hierarchical model,the center model,and the center-edge model.The co-authorship networks conforms to the power-law distribution,and a preferential attachment model in the optimized directed network is proposed according to the expansion law of the network.
