Abstract: The Internet became the platform for debates and expression of personal opinions on various subjects. Social media have assumed an important role as a tool for interaction and communication between people. To understand this phenomenon, it is indispensable to detect and assess what characterizes hate speech and how harmful it can be to society. In this paper we present a comprehensive evaluation of Portuguese-BR hate speech identification based on BERT model and ML models as baseline. The BERT model achieves higher scores compared to the machine learning algorithms, indicating better overall performance in distinguishing between classes.
