In this work, we addressed the Violent Event Identification (VEI) task by exploiting Bidirectional Encoder Representations from Transformers (BERT) in combination with Multi-Task learning approaches. Our results indicate that the proposed architecture is able to leverage information about the crime categories for effectively detect the mention of a violent act within a tweet. Our approach obtained the best performance (F1=0.77) among 11 different teams and a total of 32 different submissions.}, pdf = {https://publications.idiap.ch/attachments/papers/2022/Vallejo-Aldana_IBERLEF2022_2022.pdf} }
