高校在线社交网络谣言传播模型

A rumor propagation model of online social network in colleges and universities

针对高校思想政治工作特点,将在校师生分为无知者、传谣者和智者三类,建立了一类在线社交网络谣言传播模型;应用微分方程定性理论讨论了模型的边界平衡点和正平衡点的局部稳定性,仿真研究了通过控制模型参数达到控制谣言传播的策略.结果表明,只有教师(智者)经常联系学生、及时告知突发事件真相、正确引导学生,并通过网络舆情教育讲座等形式提升学生辨别是非的能力,努力实现“谣言止于智者”,才能有效抑制网络谣言的传播.

According to the characteristics of ideological and political work in colleges and universities,the teachers and students are divided into three categories:ignorant,spreader and intellect,and a kind of online social network rumor spreading model is established.The local stability of the boundary equilibrium points and the positive equilibrium points of the model is discussed by using the qualitative theory of differential equation.The strategy of controlling rumor propagation by controlling the model parameters is studied by aid of simulation experiments.Results show that the teachers(intellects)often contact students,inform the incident truth,guide students to improve ability of distinguishing right from wrong by online public opinion education,and strive to do“rumors stop at the wise man”,then the spread of internet rumors will be controlled effectively.
