Item Análise de sentimentos de tweets relacionados a vacinas antes e durante a pandemia da COVID-19 no Brasil(2023-03-01) Silva, Íkaro Alef de Lima; Andrade, Ermeson Carneiro de; http://lattes.cnpq.br/2466077615273972; http://lattes.cnpq.br/7938306473921402In early 2020, the COVID-19 disease spread rapidly around the world and one of the ways to fight it is the vaccine. Governments faced problems with fake news and anti-vaccination groups. Thus, it is necessary to understand the feelings of the population in order to propose efficient public policies. This article describes a sentiment analysis on vaccine-related tweets in Brazil from June 2020 to June 2021. The results revealed peaks in total tweets in January and May 2021, the predominance of positive tweets, and feelings of confidence, fear, submission and sadness. They are also associated with former President Jair Bolsonaro. The negative polarity was the least common, showing that the Brazilian population was receptive to vaccines.Item BRIMO: uma ferramenta para análise de sentimentos(2022-04-08) Sales, Otávio Alves Guedes; Andrade, Ermeson Carneiro de; http://lattes.cnpq.br/2466077615273972; http://lattes.cnpq.br/9546787079254144Twitter is one of the fastest growing social networks in recent years, being one of the main platforms for people to share their opinions through short posts called tweets. Every trending topic generates rich discussions, and an analysis of people’s sentiments about a topic provides a more comprehensive understanding of the subject. However, to our knowledge, there are no tools that make this type of analysis accessible to the general public. Thus, we propose BRIMO, a free web tool with simple and intuitive interface, which allows the analysis of sentiments quickly and objectively, through graphical representations of data. We evaluated BRIMO’s usability and usefulness with target users. The results indicate that the tool has great usability according to the criteria used, in addition to being useful for several purposes, in the perception of participants.
