异质CA模型上含有导控策略的网络舆情传播研究

Heterogeneous cellular automaton model containing guidance and control strategy of Internet public opinion propagation

为了研究网络舆情在导控机制下的传播特点,并针对解析范式无法模拟微观个体交互产生宏观行为的缺点,在元胞自动机模型上,考虑舆情个体异质属性与个体之间意见交互特征,建立了一种含有导控策略的网络舆情控制模型。在此基础上,定义元胞基于邻域影响和本身异质属性决定的状态转换规则,提出了针对不同类别元胞的导控策略。在仿真环境中,对异质性元胞状态交互与演进进行了实验,从而分析异质属性和导控策略对舆情传播的作用效果。结果表明,对易感类、接触类和传播类元胞进行引导达到的舆情导控效果各不相同。元胞自动机上的舆情导控模型能够比较真实地反映网络舆情在导控作用下的传播情况。

In order to study the propagation characteristics and control mechanism of Internet public opinion, with considering the fauh of that analytical paradigm can＇ t simulate the procedure of micro individuals interacting bringing into existence of macroscopic behavior, the heterogeneous attributes of public opinion individuals, and the characteristics of opinion interaction characteristics, this paper put forward an Internet public opinion propagation model containing control strategy based on the cellular automata model. On this basis, this paper defined cellular state transition rules which were caused by neighborhood effects and heterogeneous attributes, and proposed a variety of guidance effects to heterogenous Internet individual under the guidance and control strategies of public opinion. In the simulation environment, the experiment obtained some different revo- lution results of heterogenic cellular with analysis of impact of heterogeneous properties and control strategies on public opinion transmission effects. The experimental results show that these three kinds of guidance and control effects of each strategy are not identical. Using the characteristics of cellular automata model to establish and simulate the propagation of Internet public opinion, reflects a real-context of Internet public opinion evolution under guidance and conrol strategies.
