Fully funded PhD thesis in argumentation theory

Place: CRIL CNRS Université d’Artois, Lens (France)

Starting date: September / October 2023

Duration : 3 years

ANR project AGGREEY (An argumentation-based platform for e-democracy)
studies e-democracy and aims at proposing tools based on AI and
argumentation theory in order to improve the quality of public debate.

As online argumentation systems become increasingly prevalent, the volume
of arguments and options within these systems continues to grow. This
presents a significant challenge for human analysts, who struggle to
manually track changes, understand the various arguments and their
relationships, and make sense of the vast amount of information.

To address this challenge, AGGREEY proposes to use artificial intelligence
and argumentation theory to study these systems. Among the numerous pieces
of information to be identified and processed, this thesis will aim to
focus on the problem of votes on arguments. Currently, there is no approach
in the literature that can handle votes in an elaborated way. The existing
proposal is to calculate the ratio of positive and negative votes and use
this as a single number. The goal is to explore more ways to represent and
take into account the votes and understand the nuances of the voting
process.

Also, we want to take into account the votes of the users in order to
maximise social welfare. In other words, we want to develop methods that
start from the users’ votes and transfer this information to the
extensions, i.e. the sets of acceptable arguments. Thus, based on the votes
of a user, the system estimates her/his preferred extension. The goal is to
develop an algorithm that selects the extension that maximises the
satisfaction of all voters.
