Present and Future of Formal Argumentation (Dagstuhl Perspectives Workshop 15362)

Authors: Dov M. Gabbay, Massimiliano Giacomin, Beishui Liao, and Leendert van der Torre

Published in: Dagstuhl Manifestos, Volume 7, Issue 1 (2018)

Abstract
Formal Argumentation is emerging as a key reasoning paradigm building bridges among knowledge representation and reasoning in artificial intelligence, informal argumentation in philosophy and linguistics, legal and ethical argumentation, mathematical and logical reasoning, and graph-theoretic reasoning. It aims to capture diverse kinds of reasoning and dialogue activities in the presence of uncertainty and conflicting information in a formal and intuitive way, with potential applications ranging from argumentation mining, via LegalTech and machine ethics, to therapy in clinical psychology. The turning point for the modern stage of formal argumentation theory, much similar to the introduction of possible worlds semantics for the theory of modality, is the framework and language of Dung's abstract argumentation theory introduced in 1995. This means that nothing could remain the same as before 1995 - it should be a focal point of reference for any study of argumentation, even if it is critical about it. Now, in modal logic, the introduction of the possible worlds semantics has led to a complete paradigm shift, both in tools and new subjects of studies. This is still not fully true for what is going on in argumentation theory. The Dagstuhl workshop led to the first volume of a handbook series in formal argumentation, reflecting the new stage of the development of argumentation theory.

Present and Future of Formal Argumentation (Dagstuhl Perspectives Workshop 15362)

Authors: Dov M. Gabbay, Massimiliano Giacomin, Beishui Liao, and Leendert van der Torre

Published in: Dagstuhl Reports, Volume 5, Issue 8 (2016)

Abstract
This report documents the program and the outcomes of Dagstuhl Perspectives Workshop 15362 "Present and Future of Formal Argumentation". The goal of this Dagstuhl Perspectives Workshop was to gather the world leading experts in formal argumentation in order to develop a SWOT (Strength, Weaknesses, Opportunities, Threats) analysis of the current state of the research in this field and to draw accordingly some strategic lines to ensure its successful development in the future. A critical survey of the field has been carried out through individual presentations and collective discussions. Moreover, working group activity lead to identify several open problems in argumentation.

FSL – Fibred Security Language

Authors: Valerio Genovese, Dov M. Gabbay, Guido Boella, and Leendert van der Torre

Published in: Dagstuhl Seminar Proceedings, Volume 9121, Normative Multi-Agent Systems (2009)

Abstract
We develop a fibred security language capable to express statements of the form begin{center} ${x }varphi (x) says psi$ end{center} where ${x}varphi (x)$ is the set of all $x$ that satisfy $varphi$ and $psi$ is any formula. $varphi$ and $psi$ may share several free variables. For example, we can express the following: "A member $m$ of the Program Committee can not accept a paper $P_1$ in which one of its authors says that he has published a paper with him after 2007" begin{center} $ eg({m} [PC(m) wedge {y}author\_of(y,P_1) extbf{ says } exists p(paper(p) wedge author\_of(m,p) wedge author\_of(y,p) wedge year(p) geq 2007)] extbf{ says } accept(P_1))$ end{center}

Normative Reasoning and Consequence

Authors: Jan Broersen, Stephen Cranefield, Yehia Elrakaiby, Dov Gabbay, Davide Grossi, Emiliano Lorini, Xavier Parent, Leendert W. N. van der Torre, Luca Tummolini, Paolo Turrini, and François Schwarzentruber

Published in: Dagstuhl Follow-Ups, Volume 4, Normative Multi-Agent Systems (2013)

Abstract
In this chapter, we first provide a general introduction to the research area methodology and relevance, then we discuss normative reasoning for multiagent systems, and finally we discuss current research challenges. We cover the main issues in modern deontic logic, which is much broader than the traditional modal logic framework of deontic logic, with an emphasis to our in- tended audience. To emphasize this broadness, we typically refer to "deontic logic and normative systems" rather than deontic logic only.

Common Foundations for belief revision, belief merging and voting

Authors: Dov Gabbay, Gabriella Pigozzi, and Odinaldo Rodrigues

Published in: Dagstuhl Seminar Proceedings, Volume 7351, Formal Models of Belief Change in Rational Agents (2007)

Abstract
In this paper, we consider a number of different ways of reasoning about voting as a problem of conciliating contradictory interests. The mechanisms that do the reconciliation are belief revision and belief merging. By investigating the relationship between different voting strategies and their associated counterparts in revision theory, we find that whereas the counting mechanism of the voting process is more easily done at the meta-level in belief merging, it can be brought to the object level in base revision. In the former case, the counting can be tweaked according to the aggregation procedure used, whereas in base revision, we can only rely on the notion of minimal change and hence the syntactical representation of the voters' preferences plays a crucial part in the process. This highlights the similarities between the revision approaches on the one hand and voting on the other, but also opens up a number of interesting questions.
