【摘要】：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。
[Abstract]:In order to study the propagation characteristics of network public opinion under the guidance and control mechanism, and in order to solve the problem that the analytical paradigm can not simulate the macro behavior of micro individual interaction, it is in the cellular automata model. Considering the characteristics of individual heterogeneity of public opinion and the interaction of opinions between individuals, a network public opinion control model with guidance strategy is established. On the basis of this, a network public opinion control model is established. The state transition rules based on neighborhood influence and their own heterogeneous attributes are defined, and a guidance strategy for different types of cells is proposed. In the simulation environment, the interaction and evolution of heterogeneous cellular states are experimented. The effect of heterogeneity and guidance strategy on the communication of public opinion is analyzed. The results show that it is susceptible to public opinion. The effect of public opinion guided by contact class and transmission cell is different. The model of public opinion guidance and control on cellular automata can truly reflect the communication of network public opinion under the action of guidance and control.

【正文快照】： 0引言网络舆情传播以Internet为载体,是网民态度和意见相互交互并相对比较集中后在网络上呈现的舆论形式。网络舆情发展具有一定的自组织特性,这种特性被协同学解释为微小单元相互作用的系统出现的自发性协调行为。文献[1]就从协同学角度入手,与元胞自动机动力学结合,通过计算
