摘要:
本文在CSR传播模型的基础上提出基于移动社交网络的CSR的谣言传播模型.改进了CSR模型的传播规则和传播动力学方程,使得更符合移动SNS上用户的使用习惯.在CSR模型中的接受概率数学模型基础上,考虑个人接受阈值对接受概率的影响,更符合人类接受谣言的心理学特点.本文对该传播模型进行了理论分析.并在仿真实验中,利用多agent仿真平台对新模型和CSR模型以及SIR模型在匀质网络和异质网络中的传播效果进行了对比研究,从实验的结果来看,新的谣言传播模型在匀质网络中传播范围更广,传播速度更快.新模型具有初值敏感性的特点.
Abstract:
In this paper, we propose an improved CSR model for rumor spreading in mobile social networks. The dynamic equation of rumor spreading is modified to be suitable for user’s habit in mobile social networks. In the acceptant probability model, negative and positive social reinforcements are considered. Furthermore, the people’s accepting threshold for rumor accepting is taken into account. Analyt-ically, a mean field theory is worked out by considering the influence of network topological structure as homogeneous. Under certain conditions, rumor spreads faster and wider in the new model than CSR rumor spreading model in homogeneous networks. Meanwhile, the multi-agent simulation results indicate that the information spreading process is sensitively dependent on initial conditions.
