Séminaire de recherche : Argument Mining: from Argumentation Theory to Natural Language Processing and Back (Serena Villata)

L'équipe ERTIM de l'INALCO a le plaisir de vous inviter à son prochain séminaire de recherche, le mardi 23 janvier à 10h30, au 2 rue de Lille, Paris 7ème

Argument Mining: from Argumentation Theory to Natural Language Processing and Back
Serena Villata, I3S

Résumé

In this talk, I will present existing approaches in the area of Argument Mining, and then I will focus my own contributions in that area. In order to cut in on a debate on the web, the participants need first to evaluate the opinions of the other users to detect whether they are in favor or against the debated issue. Bipolar argumentation proposes algorithms and semantics to evaluate the set of accepted arguments, given the support and the attack relations among them. Therefore, an automated framework to detect the relations among the arguments represented by the natural language formulation of the users’ opinions is needed. My talk addresses this open issue by proposing and evaluating the use of natural language processing methods to identify the arguments and predict the relations between them. Three scenarios will be discussed, namely online debates, Twitter and political speeches. I will conclude with an overview about the open challenges in the Argument Mining research area.

Bio

Serena Villata is a CR1 researcher at CNRS in the I3S Laboratory in Sophia Antipolis. Her work focuses on argumentation theory, and spans from formal models of argumentation to natural language-based and emotion-based ones. She is the author of over 60 scholarly publications including 11 journal articles and 4 book chapters. She was invited to co-author a chapter on Processing Argumentation in Natural Language Texts in the Handbook of Formal Argumentation. She co-organized the seminar Frontiers and Connections between Argumentation Theory and Natural Language Processing in July 2014 (Bertinoro, Italy), one of the first attempts to put together researchers from computational linguistics and from argumentation theory.
