具有自我学习机制的网络谣言传播与仿真研究

Propagation and Simulation Research of Network Rumors with Self-Learning Mechanism

将社交网络中的个体设为健康者(S)、传播者(I)、反击者(C)和免疫者(R)4种状态,根据不同状态之间的转移机制建立了SICR谣言传播模型.针对"人云亦云"的社会从众心理,引入个体的自我学习机制,基于BA无标度网络仿真分析了自我学习机制以及初始传播者、天然反击者重要性对谣言传播行为的影响.结果显示:自我学习机制能够促进谣言传播;初始传播者越重要,谣言传播范围越广、速度越快;天然反击者的重要性越高,抑制谣言传播的效果越明显.

The individuals in social networks are divided into four states, susceptible （S）, infective （I）, counterattack （C） and refractory （R）, a kind of transition rule between different states is introduced, and then a new SICR rumor propagation model is established. Based on the social conformity behavior of ＂follow the herd＂, this paper introduces a self-learning mechanism in the process of rumor propagation. The effects of self-learning mechanism and the importance of initial infective or counterattack on rumor diffusion are simulated and analyzed based on BA free-scale networks. The results show that self-learning mechanism can promote rumor diffusion; the more important the initial infective is, the wider the sprea-ding range of the rumor will be; and the more important the initial counterattack is, the better the effect of inhibiting rumor diffusion will be.
