基于Multiagent的突发事件网络舆情演化

The Evolution of Network Public Opinion for Emergencies by Multiagent

针对突发事件的传播过程,采用定性与定量相结合的方法,提出了突发事件网络舆情传播的“五段六点”模式。根据贝叶斯概率原理,给出了Agent的决策规则,以网络结构的方式体现Agent之间的内在联系,建立了基于Multiagent分布的突发事件网络舆情传播模型。通过仿真分析Agent情感态的演化,验证了该模型的有效性,表明该模型能够较好地分析网络用户对突发事件网络舆情传播的演化趋势。

Aiming at the dissemination process of emergencies,combining qualitative and quantitative methods,a“five segments and six points”mode of network public opinion dissemination of emergencies is proposed.According to the principle of Bayesian probability,the agent's decision-making rules are given,the internal connection between agents is reflected in the way of network structure,and the emergent network public opinion propagation model based on Multiagent distribution is established.The effectiveness of the model is verified by simulation analysis of the evolution of agent′s emotional state,which shows that the model can better analyze the evolution trend of network users′dissemination of public opinion on emergencies.
