一个科研合作复杂网络模型的实证研究

Research of a complex network model on scientific collaboration

在加权条件下建立了一个作者科研合作的复杂网络模型.通过理论分析和仿真验证,该网络模型共有24个连通子网络;最大连通子网络具有无标度网络特征,点权、边权服从幂律分布且具有厚尾趋势,度数越小的节点其聚集系数越高,平均距离较小具有典型的小世界特征,小团体现象明显,团队科研合作能力较强.

The author collaboration complex network is presented and analyzed. It is found that the largest connected collaboration sub-network appears to be a scale-free network, and it behaves some like a small-world. Other characters such as the degree distributions, the cluster coefficients, and the average distance in this sub-network are discussed.
