簇结构网络的突发事件信息同步传播演化模型研究

Study on Evolution Model of Information Synchronous Dissemination of Emergent Events Based on Cluster Structure Network

摘要: 以“H7N9”突发事件信息传播特征为基础，理论构建突发事件信息传播网络模型，并对网络簇结构进行拓扑分析；针对社会公众对突发事件信息认知、理解和扩散行为的异质性，构建基于主体观点动态变化特征的突发事件信息同步化传播演化模型，并进行模拟仿真分析。研究发现，网络规模水平和簇结构特征直接影响突发事件信息同步传播的演化过程；传播主体观点变化率及其同步化行为与网络耦合强度一定程度上呈正相关；突发事件信息传播同步化过程受传播主体初始观点状态和传播主体在网络中的威望影响。

Abstract: Based on the information dissemination characteristics of “H7N9” emergency, an information dissemination network model of emergency events is theoretically constructed and its cluster structure of topology is analyzed. Considering the behavior heterogeneity of information cognition, comprehension and diffusion of social public, the evolution model of information synchronous dissemination and its simulation analysis is constructed based on the features of one’s view dynamic change. The article draws the conclusions that network scale and cluster structure characteristics directly affect the evolution of information synchronous dissemination; the change rate of one’s viewpoint and its synchronization behavior is positively related to the coupling strength of the network; the information synchronous dissemination process of the emergency events is influenced by the initial state viewpoint of the social ones and the authority of the one in the network.
