为研究突发事件谣言在微博上的传播机制,通过分析微博用户获取以及传播谣言的行为特征,考虑微博谣言获取的非常规渠道以及谣言传播的滞后性等特点,基于传染病动力学,构建了适用于微博网络的SC1C2IR谣言传播模型。最后在无标度网络上对传播过程进行了模拟仿真,分析了谣言传播机理和网络参数对传播过程的影响;并通过对比真实数据与仿真数据,验证了模型的合理性,结果表明新模型能够较为准确的描述谣言传播过程。
In order to study the process of emergency rumor spreading, Weibo users" behavioral characteristics of accessing and spreading rumors were analyzed. Based on the theory of dynamics of infectious diseases, and taking into consideration of the unconventional chan- nels of obtaining Weibo rumors and rumors" time lag characteristics, a SC1 C2IR Weibo rumor spreading model was constructed. Finally, rumor spreading process was simulated based on the scale-free network, and the spreading mechanism and the influence that the network parameters have on the spreading process were analyzed. The rationality of the model was verified by comparing the real data and simula- tion data and the results showed that the new model can more accurately describe the spread of rumors.
