Key Nodes Analysis of Microblogging Public Opinion Spread about Public Emergencies-Such as the Missed Malaysia Flight MH370

Abstract

Microblog plays a very important role in the process of public opinion dissemination after the occurrence of public emergencies. As a Micro blogging platform based on user information sharing, dissemination and access, it is suitable for using social network analysis method to analyze because of forming a network structure between the microblogging users. In this paper, we use the social network analysis method to explore the network structure, node position and key nodes feature such as the missed Malaysia Flight Mh370. The research shows that the network structure of the microblogging public opinion about public emergencies is loose, and the key nodes are more important that makes the public opinion spread quickly. Users participating in the dissemination of public opinion have obvious domain features. The relevant regulatory authorities need to focus on the key nodes (opinion leaders) of public opinion-prone areas.
