基于两层可变聚类系数无标度网络的即时信息传播建模和仿真

即时通讯网络已成为大众信息传播的主要途径,研究了即时通讯网络信息传播的性质、规律以及预测、引导的方法和手段,利用可变聚类无标度网络模型建立了新的即时通讯网络的二层模型,并制定了信息传播规则.通过实验仿真对群数、聚类系数、传播者和免疫者的变化观察,发现群数越多则聚类系数越大,传播者峰值越高.以及免疫者也相应地有所提高,从而对信息传播的影响也越大.

Modeling and simulation of instant information propagation based on two-layer scale-free networks with tunable clustering

Since the instant messaging network is the main way to propagate information, this paper studies the nature, the rule and the forecasting and guiding methods of information propagation in instant messaging network. A new two-layer model of instant messaging network using scale-free networks with tunable clustering was proposed, and its information propagation rules were formulated as well. Through the experimental simulation on the diversification of group numbers, clustering coefficient, spreader and stifler, it is found that the larger the group number is, the larger cluster coefficient and the higher maximum spreader and stifler are, and thus the group number and clustering coefficient have greater influence on the information propagation.
