关于时变协作网络

On time-varying collaboration networks

Matheus P. Viana, Diego R. Amancio, Luciano da F. Costa

摘要:

科学合作的模式经常被研究的复杂网络,而不参考时间的演变。在目前的工作中,我们得到的协作网络(从arXiv库)参数化沿时间。通过定义仿射群的概念,我们确定了科学合作中的几个有趣的趋势,包括仿射群的平均大小呈指数级增长,而作者的数量呈幂律增长。因此,我们能够确定,通过外推,当一个单一的仿射群预计出现的可能日期。每个研究人员都确定了特征合作模式,他们的分析表明,较大的仿射群体往往不太稳定。

英文摘要:

The patterns of scientific collaboration have been frequently investigated in terms of complex networks without reference to time evolution. In the present work, we derive collaborative networks (from the arXiv repository) parameterized along time. By defining the concept of affine group, we identify several interesting trends in scientific collaboration, including the fact that the average size of the affine groups grows exponentially, while the number of authors increases as a power law. We were therefore able to identify, through extrapolation, the possible date when a single affine group is expected to emerge. Characteristic collaboration patterns were identified for each researcher, and their analysis revealed that larger affine groups tend to be less stable.
