Preface


This volume contains the papers presented at the 2020 edition of AI3, the Workshop
on Advances In Argumentation In Artificial Intelligence. This year, the workshop was
a track of the 19th International Conference of the Italian Association for Artificial
Intelligence (AIxIA2020), and, owing to the COVID-19 emergency, was held online
on the 25th and 26th of November 2020. This workshop was promoted by the
Argumentation in Artificial Intelligence Working Group.

Argumentation is the study of processes and activities involving the production and
exchange of arguments, where arguments are reasons for accepting or refuting a
particular conclusion or claim. As such, argumentation provides procedures for
making and explaining decisions and is able to capture diverse kinds of reasoning
and dialogue activities in a formal but still intuitive way. Over the last two decades
formal argumentation has become a main research topic in Artificial Intelligence.
Given that the study of argumentation is inherently interdisciplinary, the goal of the
workshop was to stimulate discussions and promote scientific collaboration among
scholars from different disciplines, including computer science, philosophy,
psychology, and computational linguistics.

AI3 is a traditional occasion of meeting where Italian researchers in the field of
argumentation strengthen a group identity and share their interests. Also in this
edition, the workshop gathered contributions of researchers from the international
community. A wide set of topics were discussed during the workshop, including
foundations in argumentation as well as challenges and real-world problems for
which argumentation may represent a viable AI-paradigm. Each submission
underwent a single-blind peer-review process and each paper was reviewed by at
least 3 reviewers. The workshop involved 8 papers accepted for oral presentation,
which are collected in this volume, and an invited talk. These papers dealt with
various aspects of argumentation, including concurrent languages, approximate
reasoning, as well as computational methods and semantic aspects of
argumentation.

We would like to express our special thanks to the Program Committee members,
the authors and all the attendees.
