Resumo

O objetivo deste artigo é analisar os sentimentos subjacentes em publicações do Twitter sobre a vacinação contra a covid-19. Para atingi-lo, são extraídas, mediante mineração de dados, 38.034 publicações dessa rede social e são aplicadas técnicas Machine Learning, em concreto, análise de sentimentos e análise de redes, para identificar os sentimentos que os usuários dessa rede expressam quanto à vacinação contra a covid-19. Também são identificadas as contas mais importantes do Twitter em temas de vacinação. Os resultados sugerem que, em sua maioria, os sentimentos sobre as vacinas sejam negativos. O medo e a ira, respectivamente, são as emoções mais recorrentes nas opiniões do Twitter. Por sua vez, é identificado que as contas mais relevantes pertencem a meios de comunicação, políticos e influenciadores, os quais são classificados de acordo com os principais sentimentos a respeito da vacina. Destaca-se a oposição ao governo, com sentimentos de ira, e a meios de comunicação reconhecidos, com emoções associadas à alegria.
