BRIMO: uma ferramenta para análise de sentimentos

Abstract

Twitter 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.
