Analysis of Internet Public Opinion Communication in Changsha’s Self-Built House Collapse Accident

摘要: 目的：本文基于“长沙自建房倒塌事故”这一事件来认识非常规突发事件中网络舆情的发展阶段，从而通过网络舆情监测系统积极正向引导网络舆情。方法：运用Python软件抓取各平台关于“长沙自建房倒塌事故”的相关数据，通过Matlab软件进行描述性统计分析和情绪趋势研究。结果：大众对该“长沙居民自建房倒塌事故”的主要讨论时间与情绪爆发点集中在5月1日与5月6日这两天，吻合了官方平台数据。在大众的情绪中，愤怒是远远高于悲伤的。后期舆论聚焦在关注救援情况、讨论楼房倒塌背后的自建房违建、各地网民反映当地自建房加盖的乱象上。结论：在非常规突发事件中，网络舆情是社会舆情在网络上的反应和投射，它既充当非常规突发事件中危机化解的助推器，又可能成为危机言论的诱发器和放大器。对于网络舆情的预警需要优化舆情传播的机制，净化互联网上的言论信息。

Abstract: Objective: Based on the incident of “the collapse of a self-built house in Changsha”, this paper understands the development stage of online public opinion in unconventional emergencies, so as to actively guide online public opinion through the online public opinion monitoring system. Methods: Python software was used to capture the relevant data of “the collapse accident of self-built houses in Changsha”, and descriptive statistical analysis and emotional trend research were carried out by Matlab software. Results: The main discussion time and emotional explosion point of the “Changsha residents’ self-built house collapse accident” were concentrated on May 1 and May 6, which were consistent with the official platform data. In the public mood, anger is far higher than sadness. In the later period, public opinion focused on the rescue situation, discuss-ing the illegal construction of self-built houses behind the collapse of buildings, and netizens everywhere reflected the chaos of local self-built houses. Conclusion: In unconventional emergencies, network public opinion is the reaction and projection of social public opinion on the network. It not only acts as a booster for crisis resolution in unconventional emergencies, but also may become an inducer and amplifier of crisis speech. The early warning of online public opinion needs to optimize the mechanism of public opinion dissemination and purify the speech information on the Internet.
