社交网络传播路径对谣言传播影响的研究

Study on Rumor Spreading Model Considering Propagation Path in Social Networks

传播路径是社交网络谣言传播动力学的重要研究内容,定义传播路径的特征参数并研究各参数在谣言传播中的作用是十分重要的.基于控制理论知识,通过引入静态增益K、时间常数T与纯迟延时间τ,研究了谣言传播路径的动态特性,提出了基于一阶惯性环节、一阶惯性环节加纯迟延和n阶惯性环节加纯迟延的三种谣言传播路径模型,进行了理论分析和仿真.通过与基于复杂网络理论和基于复杂适应系统理论的谣言传播研究方法进行比较,提出的新方法直观地解释了谣言传播中传播路径的影响.仿真结果验证了模型的有效性.

The Propagation path is an important research content of social network rumor spreading dynamics. It is very important to define the characteristic parameters of the propagation path and to study the effect of each parameter on rumor propagation. By introducing static gain K,time constant Tand pure delay timeτ,we study the dynamic characteristics of the rumor propagation path based on control theory and propose three kinds of rumor propagation path models based on first-order inertia link,first-order inertial link with pure time-delay and N order inertial links with pure time-delay respectively. This article has conducted theoretical analysis and computer simulation analysis. To compare the two research methods basing on the complex networks theory and complex adaptive systems theory,the proposed new method in this paper can explain the effect of propagation path on the rumor-spread-process more visually.The simulation result shows that proposed model is effective.
