This study examined discourses related to an Indonesian soccer stadium stampede on 1st October 2022 using comments posted on Twitter. We conducted a lexicon-based sentiment analysis to identify the sentiments and emotions expressed in tweets and performed structural topic modeling to identify latent themes in the discourse. The majority of tweets (87.8%) expressed negative sentiments, while 8.2% and 4.0% of tweets expressed positive and neutral sentiments, respectively. The most common emotion expressed was fear (29.3%), followed by sadness and anger. Of the 19 themes identified, "Deaths and mortality" was the most prominent (15.1%), followed by "family impact". The negative stampede discourse was related to public concerns such as "vigil" and "calls for bans and suspension," while positive discourse focused more on the impact of the stampede. Public health institutions can leverage the volume and rapidity of social media to improve disaster prevention strategies.
本研究利用推特上发布的评论，对与2022年10月1日印度尼西亚足球场踩踏事件相关的话语进行了分析。我们进行了基于词汇的情感分析，以识别推文中表达的情感和情绪，并进行了结构化主题建模，以识别话语中的潜在主题。大多数推文（87.8%）表达了负面情绪，而分别有8.2%和4.0%的推文表达了正面和中性情绪。表达最常见的情绪是恐惧（29.3%），其次是悲伤和愤怒。在确定的19个主题中，“死亡与死亡率”最为突出（15.1%），其次是“家庭影响”。负面的踩踏事件话语与公众关注的“守夜”和“呼吁禁令和暂停”等问题相关，而正面话语则更多地关注踩踏事件的影响。公共卫生机构可以利用社交媒体的数量和速度来改进防灾策略。
