Characterization of Public Opinion on Political Events in Brazil Based on Twitter Data

In this work we characterize Brazilian online population sentiment on different political events using data from Twitter and we also discuss the advantages of the usage of this social media as data source. The results demonstrated that the Brazilian population uses Twitter to manifest their political view, expressing both positive and negative sentiments regarding political events. This kind of characterization may contribute to build a critical opinion of Brazilian people, once they would not be limited by what is being divulgated by typical media, such as television and newspapers. Additionally, we reinforced the applicability of social media, as Twitter, to make this kind of characterization.
