摘　　要：为了准确刻画网络舆情的变化规律,针对经典元胞自动机存在的不足,考虑网络舆情主体的可移动因素,提出一种基于移动元胞自动机的网络舆情传播模型。首先对经典元胞自动机的工作原理进行分析,提出移动元胞自动机模型,然后根据网络舆情的特点,制定网络舆情主体状态转换规则和移动规则,建立移动元胞自动机的网络舆情传播模型,最后采用Matlab 2011对网络舆情演化过程进行仿真分析。仿真结果表明,舆情主体移动概率对网络舆情传播速度和同质化率影响比较大,移动元胞自动机模型可以很好地描述网络舆情的实际传播过程。In order to accurately depict the variation of network s public opinion dissemination,aiming at the deficiencies of classical cellular automata,consider mobile factors in network public opinion,a public opinion dissemination model in networks based on mobile cellular automata is put forward in this paper. Firstly,the working principle of the classical cellular automata model is anal sized and mobile cellular automata model is proposed,and then according to the characteristics of the network public opinion,transition rule and movement rules of the network public opinion subject state are made and establish network public opinion dissemination model based on mobile cellular automata,lastly,the evolution of network public opinion is simulation and analysis on Matlab 2011. Simulation results show that the moving probability is main factor of network public opinion dissemination,and mobile cellular automata model can describe the real dissemination process of network public opinion.
