基于H7N9的突发事件信息传播网络簇结构特性研究
Study on the Cluster Structural Characteristics of Emergency Information Propagation Networks Based on H7 N9
摘要
Abstract
Complex information dissemination process happens when emergency occurs. By citing relationship of certain topic, informa-tion propagators form a propagating network which has specific network structure characters and affects the speed and range of information propagation, and eventually affects the development trend. Taking H7N9 as an example, we formed the H7N9 network topology based on the related data collected by web crawlers, and systematically analyzed the basic characteristics and internal cluster structure of the propaga-ting network according to its adjacency matrix and the cluster structure discovery algorithm based on information entropy. Empirical study shows that the modularity of network is significant, and the largest and the second largest cluster in network grow as approximately S-line as time goes by. This result is very important in effective control of the emergence and dissemination of network public opinion.关键词
