摘要
通过构建带有讨论机制的舆情传播模型,研究媒体作用下三分意见群体舆情演变的内在规律。在参考疾病传播模型SIR(Susceptible,Infected,Recovered)、和媒体干预下的二分意见模型SIa Ib R(Susceptible,Infected-a,Infected-b,Recovered)的基础上,提出了带有三分意见群体舆情演变的SI3R(Susceptible,triple Infected,Recovered)模型。与二分意见模型不同的是,三分意见模型引入了中立群体这一概念,并且在传播群体中占有较大比重。通过对中立群体的影响,媒体能够发挥更有效的作用。给出了三分意见群体模型及其动力学方程,通过数值求解,模拟了有无媒体作用的差异,以及分歧度、渗透率的变化对传播过程的影响。
By constructing a dissemination model with a discussion of the Intemet public opinion, the paper studies the inner rule of the public opinion evolution of the triple opinion group under the influence of the media. In reference to disease transmission model SIR（Susceptible, Infected, Recovered） and the two opinions model SIalbR（Susceptible, Infected-a, Infected-b, Recovered）, this paper presents a public opinion evolution model of the triple opinion group SI3R（Susceptible, triple Infected, Recovered）. The SI3R model introduces the concept of neutral groups, population. Through the influence of neutral groups, and occupies a large proportion in the spread of the the media can play a more effective role. This paper gives the triple opinion group model and its dynamics equation, and simulates the difference whether the media is functioned or not. The influence of different divergence and permeability on the propagation process is shown as well.
