Présentation
I am a third-year PhD student in Computer Science (CS) at Université Côte d’Azur, Inria, CNRS, I3S, and a member of the Wimmics Research Team working on Implicit and Subtle Abusive Language using Machine Learning and Natural Language Processing (NLP). My current research interests lie in the intersection of linguistics and NLP. My thesis topic aims to properly represent implicit and subtle (instances with irony, sentiment, exaggeration, circumlocution, etc) for abusive language detection and downstream tasks. After a proper representation of these notions with the WIMMICS team we aim for generating counter-narratives automatically in order to provide an informative answer that counter-argues a message, giving more context to social media users.
