International Committee for Computational Linguistics. https://doi.org/10.18653/v1/2020.semeval-1.259https://hdl.handle.net/10272/24660This paper describes the systems developed for I2C Group to participate on Subtasks A and B in English, and Subtask A in Turkish and Arabic in OffensEval (Task 12 of SemEval 2020). In our experiments we compare three architectures we have developed, two based on Transformer and the other based on classical machine learning algorithms. In this paper, the proposed architectures are described, and the results obtained by our systems are presented.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/conference output10.18653/v1/2020.semeval-1.259open access3304 Tecnología de Los Ordenadores
