研究社交网络的拓扑结构有利于深刻理解信息在人际网络中的传播过程以及社交网络所具有的拓扑特性.考虑到信息传递具有有向性,通过结合现实生活中信息传播所遵循的规律构造加权有向拓扑模型模拟信息传递的动态性,从而更好地仿真社交网络的拓扑结构.实验结果表明,模型所生成网络的拓扑结构的度、势分布以及度—势相关性具有明显的幂律分布特性;同时,通过分析所生成网络的聚类系数、核数和基尼系数,验证了其具有社交网络的聚集特性、层次性和异质性.
研究社交網絡的拓撲結構有利于深刻理解信息在人際網絡中的傳播過程以及社交網絡所具有的拓撲特性.攷慮到信息傳遞具有有嚮性,通過結閤現實生活中信息傳播所遵循的規律構造加權有嚮拓撲模型模擬信息傳遞的動態性,從而更好地倣真社交網絡的拓撲結構.實驗結果錶明,模型所生成網絡的拓撲結構的度、勢分佈以及度—勢相關性具有明顯的冪律分佈特性;同時,通過分析所生成網絡的聚類繫數、覈數和基尼繫數,驗證瞭其具有社交網絡的聚集特性、層次性和異質性.

The topology modeling of the social network is propitious to understanding the transmission process of infor-mation and the topology characteristic of the real friendship network. Considering the directed characteristic of informa-tion spread, the dynamic process of information dissemination was simulated, and moreover, the weighted directed to-pology model in order to well emulate the topology structure of the social network was constructed. Simulation results show the degree and strength distribution as well as the correlation between degree and strength of the network generate by the topology model embody obvious power-law characteristic, and meanwhile, through analyzing the clustering coef-ficient, coreness and Gini coefficient of the network, the generated network has the characteristics of clustering, layer and heterogeneity which are shown in the real friendship network is verified.
