突发事件信息传播中的网络信源地位关系研究

Study in Position Relations of Network Information Source in Information Spreading of Emergencies

以近年来14个大桥坍塌事件作为研究对象,通过追溯性研究截取参与主题事件传播的网络信源,在"信源—事件"的隶属关系背景下,构建信源关系网络。通过信源关系网络中凝聚子群的分析发现,在突发事件信息传播中,不同的网络信源在信息传播中的作用与地位也不尽相同。其中处于网络信息传播统驭地位的是由官方平台网站、著名社区网站、大型门户网站和主流视频媒体网站等共同组成的核心信源子群。

To 14 events of bridge collapse in recent years as the research object, this article extracts network information source that involved theme event spreading through a retrospective study. In the ＂source-event＂ affiliation background, the network of source relationship is constructed. Through the cohesive subgroup analysis in network of source relationship, in the information spreading of emergencies, the roles and positions of different sources are not the same. The core source subgroup which is on a hub position in information spreading constitutes by official website, famous community site, large portals and mainstream video media websites.
