摘要
目前,社交媒体已经成为网络谣言滋生的温床,其庞大的用户规模,以及即时性、开放性等特点,使得谣言传播的广度和速度远远高于现实社会网络,从而对人们的生活和社会的稳定产生巨大的影响.为此,基于传染病动力学及"反沉默螺旋"理论,构建了考虑辟谣行为及网络结构的社交媒体谣言传播模型;并进一步分析了模型中无谣言平衡点和谣言存在平衡点的存在性和稳定性,计算了模型的基本再生数;利用MATLAB对模型中各参数变化对谣言传播的影响进行了仿真分析,并对部分参数进行了敏感性分析;利用实际案例对模型进行了进一步的分析与验证;最后,给出了控制社交媒体中谣言传播的策略建议.
Nowadays,social media has also become a breeding ground for online rumors.The huge number of users on various social media platforms,as well as the characteristics of instantaneity and openness,make the spread of rumors much wider and faster than the real social network.Thus,the spread of rumors on social media platforms has a great impact on people’s lives and social stability.Based on the classic SIR model and the theory of"Spiral of Anti-silence",this paper establishes a rumor spreading model in social media with debunking behavior,and then analyzes the existence and stability of rumor-free equilibrium and rumor-existence equilibrium in the model,as well as calculates the basic reproduction number on rumor spreading.Furthermore,this paper simulates the influence of parameter changes on rumor spreading by MATLAB,analyzes the sensitivity of some parameters in this model,and then analyzes and validates the proposed model by practical cases.Finally,some suggestions are put forward in order to control the spread of rumors effectively.
