| 摘 要： | 以情报学领域的12种期刊在2000-2009年间的7 389位作者形成的合著网络为例,分别基于度和K-shell,介数和K-shell对作者传播影响力进行比较分析。结果表明,K-shell值较度、介数能更好地表征作者的传播影响力。这种方法可以推广到基于科技文献数据的其他网络中,如识别文献共被引网络、文献耦合网络中最具传播影响力的关键文献。

| Abstract: | Based on the data comes from 12 journals between 2000-2009 which contains 7 389 different authors,this paper computes the degree,betweenness centrality and K-shell and makes a comparative analysis.The results show that K-shell does better in identification of influential spreaders in co-author network.This method can be also used in co-citation network and coupling network for identification of influential spreaders. |
