基于科研论文的作者合作关系簇的演化特性,建立了一个科研合作网络的簇涌现模型。通过分析网络模型的内部特性,发现该类网络是一个无尺度网络,而且网络的簇度分布和节点连接强度分布具有相同的幂指数。最后应用计算机仿真实验和作者合作网络实证分析,发现实验结论和实证结论与簇涌现模型的理论分析结论一致,对本文结论提供了强有力的支持。
Based on the evolvement characteristics of the author collaboration cliques in scientific theses, this article constructs an emerging model of scientific cooperation network. By analyzing the interior features of the model, it' s found that this kind of network is a scale-free network, and the cliques degree and the strength degree have the identical power exponent. Finally, the article conducts a computer simulation experiment and an author collaboration network demonstration analysis, and it' s found that the results of the experiment and the demonstration are consistent with those of the theoretic analysis, which supports our conclusion strongly.
