Secondary Public Opinion Network Sentiment Analysis of Public Events Based on Social Network Analysis: Taking the Weibo topic # Huang Yangtiantian's Father Under Investigation # as an Example

Abstract

In the digital era, the "secondary" public opinion phenomenon in public events is becoming more prominent. Original events can lead to new issues due to improper official responses or conflicting social sentiments, worsening public opinion crises. This study focuses on the Weibo topic #Huang Yangtiantian's Father Under Investigation#, using social network analysis to build a public opinion dissemination network based on Weibo retweets. It explores the characteristics of secondary public opinion spread. Results show the network has high sparsity, core node dominance, strong community differentiation, and flat transmission. Information spreads rapidly but rational discussion is limited, increasing governance difficulty. The study offers a social network analysis perspective for public opinion management, stressing the importance of optimizing information dissemination paths, guiding core nodes, and breaking community barriers to enhance guidance effectiveness and maintain social stability and government credibility.
