nalysis of Micro-blog Public Opinion Periodic Propagation Network in Social Hotspot Events Based on SNA——An Empirical Study on “Yu Huan”

Abstract

Abstract:

The active participation of large user groups, convenient message post style and the unique information fission mode make micro-blog become an amplifier of public opinion. Analyzing the propagation law of public opinion and effectively leading it to healthy development are a hot topic of current academic research fields in China. The development and evolution of public opinion present phased features. Taking the case of "Yuhuan" in 2017 as an example, this paper uses social network analysis to explore the network structure characteristics of the event in all stages. The research results show that the stage propagation network of public opinion about "Yuhuan" is relatively sparse, while the propagation rules of each stage are quite different. The generation stage shows a typical de-centralization characteristic. Due to increase of interaction and collision of views, the outbreak stage presents a centralized feature. The extinction phase is dying accompanied by a large number of nodes leaving the network. The information superiority and control advantage of micro-blog users in public opinion communication network are influenced by popularity, professionalism, credibility and authority.

Key words: micro-blog public opinion, social network analysis, dissemination network, periodic
