Humor, support and criticism

The use of social networks to share information and express opinions has significantly grown in recent years. In this context, the microblogging platform Twitter has been used in the political scene by governments and citizens for different purposes. Brazil is experiencing a political crisis in recent years that led to the impeachment of Dilma Rousseff president in 2016 and the investigation of several corruption scandals in 2017. This text proposes a taxonomy for discourse analysis to help understand the intent and types of Twitter users' conversation about political scandals. In this paper, this taxonomy is described, and an analysis is presented about four political episodes that occurred in Brazil in 2017. It was possible to verify how this taxonomy can help to identify different types of user manifestations, allowing us to analyze patterns of behavior. The main contributions include: providing a new taxonomy to enable the opinion analysis about political facts and crisis; investigating the perception of social media users in Brazil about political points; and identifying the benefits of using visualizations in this context.
