I studied computer science at Université d'Artois, Lens (France) where I obtained my Bachelor degree (2012) and my Master degree (2014). Afterwards, I worked as a PhD student at the Centre de Recherche en Informatique de Lens (CRIL Laboratory, Research Centre in Informatics in Lens, Artois University, France). My Ph.D. on the topic Ranking-based semantics for Abstract Argumentation has been supervised by Élise Bonzon (LIPADE), Sébastien Konieczny (CRIL) and Nicolas Maudet (LIP6) and has been funded by the project ANR AMANDE (Advanced Multilateral Argumentation for DEliberation). I defended my thesis in December 2017. Since September 2017, I am Assistant Lecturer (ATER) at the University Institute of Technology of Lens.

My thesis about "Ranking-based Semantics for Abstract Argumentation" has been supervised by Élise Bonzon, Sébastien Konieczny and Nicolas Maudet.
Description : Dung’s theory of abstract argumentation is a formalism that represents conflicting information using an argumentation framework which is a directed graph such that its nodes represent the arguments, and the directed edges represent the attacks between arguments. Extension-based semantics have been introduced to determine, given an argumentation framework, the justifiable points of view on the acceptability of the arguments. However, these semantics are not appropriate for some applications (e.g. decision making, online debate platforms). So alternative semantics, called ranking-based semantics, with a more fine-grained assessment of the acceptability status of arguments, have recently been evolved. Such semantics produces, for a given argumentation framework, a ranking on its arguments from the most acceptable to the least one(s). The overall aim of this thesis is to propose and study ranking-based semantics in the context of abstract argumentation. We first define a new family of ranking-based semantics based on a propagation principle which allow us to control the influence of non-attacked arguments on the acceptability of arguments. We investigate the properties of these semantics, the relationships between them but also with other existing semantics. Then, we provide a thorough analysis of ranking-based semantics in two different ways. The first one is an empirical comparison on randomly generated argumentation frameworks which reveals insights into similarities and differences between ranking-based semantics. The second one is an axiomatic comparison of all these semantics with respect to the proposed properties aiming to better understand the behavior of each semantics. At last, we question the ability of the existing ranking-based semantics to capture persuasion settings and introduce a new parametrized ranking-based semantics which is more appropriate in this context.
