摘要:
社交网络已经成为信息交流的重要媒介,直接影响谣言传播的速度和范围,因此研究谣言传播机制对谣言传播规律理解具有十分重要的意义。 考虑到关于少数不相信谣言的理性者对谣言传播影响的研究还很少,社交网络群组成员通过群组共享和传播信息方式对谣言传播的影响大,在均匀网络和非均匀网络上构建了理性者交互群组传播谣言传播模型。 利用微分动力学方法和下一代矩阵理论给出模型的无谣言平衡点和基本再生数。 文中首先使用数值仿真验证模型的正确性,然后通过 Monte Carlo 方法在 ER,WS,BA,Facebook 网络上分别模拟真实情况下未知者、理性者以及传播者的动态变化。 仿真结果表明,当谣言逐渐消失时,4 种网络中的未知者密度和理性者密度均能趋于稳定;BA 网络和 Facebook网络谣言传播速度和消失速度快于 ER 网络和 WS 网络。 更大规模的群组能够增加谣言传播影响范围。 更可信的理性者显著降低了网络谣言的传播时间和传播者密度峰值。
Abstract:
Social networks have become an important information media, resulting in the speed and range of rumor propagation.Therefore,it is of great significance to study the rumor spreading mechanism to understand the rumor spreading rules well. Considering few attentions to the influences of rational people who do not blindly faith in rumors,and members of social network groups through group sharing and propagation during the spreading of rumors, a rumor spreading model considering group propagation and rational interaction in homogeneous networks and heterogeneous networks is developed. The differential dynamic method and the next generation matrix theory are exploited to calculate rumor free equilibrium and basic influence number of the model. Numerical simulation is conducted to verify the proposed model,and the Monte Carlo method is then used to simulate the dynamic changes of the ignorant,the rational person and spreaders under real-world applications in the ER,WS,BA and Facebook networks. The simulation shows that both of the density of the ignorant and the rational in the four networks can reach stabilization under the condition that the rumor gradually disappearing,and the rumor in the BA and Facebook networks spread and disappear faster than that in the ER and WS networks. Theory and simulation analysis demonstrates that larger groups can enhance the influence range of rumor propagation and more credible rational people can significantly reduce the time and range of rumors propagation
