基于作者贡献的合著网络加权模式研究

Research of Weight Measurement of Co-Author Networks Based on Author Contribution

文摘社会网络分析方法越来越多地被应用到合著关系研究当中,目前几种合著网络边权计算的方法均存在各自的缺点和不足。本文针对根据合著次数及合著强度计算合著网络边权方法中将文献中各作者之间合著关系做相同处理,而不考虑不同作者之间合著关系强度差异性这一缺点,从作者贡献的角度,引入作者署名次序、通讯作者情况等因素对这种方法进行改进。并对改进前后的结果进行对比分析,结果表明基于作者贡献的合著网络模型比基于作者数量的合著网络模型更好地反映合著状态。

Social network analysis becomes more and more popular in the study of co-author relationship,but there exist specific shortcomings and defects in the present calculation methods about weight measurement in co-author networks.Against the defect that calculation methods using collaboration times and collaboration strength to calculate collaboration network weight usually conduct the same treatment to all authors in the literature and neglect the different role of different authors playing in the collaboration relationship strength,this paper improve that method from the perspective of author contribution by considering factors such as authors signature sequence,corresponding authors and so on.By comparing the results between the original and the improved methods,the results show that measure of co-author networks based on author contribution is more effective than measures based on author number in reflecting the state of collaboration.
