Abstract:
This article analyzes the media coverage of the COVID-19 vaccine by major media outlets in five Latin American countries: Argentina, Colombia, Chile, Mexico, and Peru. For this purpose, the XLM-roBERTa model was applied and the sentiments of all tweets published between January 2020 and June 2023 (n = 24,243) by the five outlets with the greatest online reach in each country were analyzed. The results show that the sentiment in the overall media and in each nation studied was mostly negative, and only at the beginning of the pandemic was there some positivity. In recent months, negative sentiment has increased twelvefold over positive sentiment, and has also garnered many more interactions than positive sentiment. The differences by platform and country are minimal, but there are markedly negative media, some more inclined to neutrality, and only one where positive sentiment predominates. This paper questions the role of journalism in Latin America during a health crisis as serious as that of the coronavirus, in which, instead of the expected neutrality, or even a certain message of hope, the media seem to have been dragged along by the negativity promoted by certain discourses far removed from scientific evidence.
摘要:
本文分析了五个拉丁美洲国家的主要媒体对COVID-19疫苗的媒体报道:阿根廷,哥伦比亚,智利,墨西哥,秘鲁。为此,应用了XLM-roBERTa模型,并分析了2020年1月至2023年6月(n=24,243)之间每个国家在线覆盖率最高的五个媒体发布的所有推文的情绪。结果表明,整个媒体和所研究的每个国家的情绪大多是负面的,只有在大流行开始时,才有一些积极因素。最近几个月,负面情绪比正面情绪增加了12倍,也获得了比积极情绪更多的互动。平台和国家之间的差异很小,但是有明显的负面媒体,有些人更倾向于中立,只有积极情绪占主导地位。本文质疑新闻界在与冠状病毒一样严重的健康危机中在拉丁美洲的作用,其中,而不是预期的中立,甚至是某种希望的信息,媒体似乎被某些远离科学证据的话语所推动的消极情绪所拖累。
