Compreendendo o papel dos sujeitos no ato de linguagem: estudo de caso das manifesta??es de 15 de mar?o de 2015 no Twitter

摘要

This article analyzes the hashtags used in interactions posted on Twitter due to the demonstrations of March 15, 2015, and the reply given by Brazilian President Dilma Rousseff and the government in a statement to the press, seeking to define the subjects of the language act, establish their role and check the communication contract effectivity. This research presents reflections by Lévy and Lemos (2010), Santaella and Lemos (2010) and Israel (2010) on digital social networks and Twitter; and Charaudeau (2014) on communication contract, language act and its subjects. From the analysis, it is clear that voters are outside the verbal configuration, assuming the role of MEc and leaving to the hashtags the one of MEe; President Rousseff is the YOUd and the government is the YOUi. It is also noted that the communication contract was signed, because the YOUi recognizes the messages from the MEc.
