Dialogical Scaffolding for Human and Artificial Agent Reasoning

Sanjay Modgil
2017 International Workshop on Artificial Intelligence and Cognition  
This paper proposes use of computational models of argumentation based dialogue for enhancing the quality and scope ('scaffolding') of both human and artificial agent reasoning.  ...  I also refer to recent concerns about the potential dangers of artificial intelligence (AI), and the consequent need to ensure that AI actions are aligned with human values.  ...  Finally, Section 6 concludes the paper. 2 From Non-monotonic Inference to Distributing Non-monotonic Reasoning through Dialogue AI research in the 80s and early 90s saw a proliferation of non-monotonic  ...

A structured argumentation framework for detaching conditional obligations [article]

Mathieu Beirlaen, Christian Straßer
2016 arXiv   pre-print
We illustrate the modularity of the general framework by considering some extensions, and we compare the framework to some related approaches from the literature.  ...  For the evaluation of arguments in favor of detaching obligations we use a Dung-style argumentation-theoretical semantics.  ...  Understood in this way, specificity cases have been studied extensively in the fields of non-monotonic logic (see e.g. [7, 5] ) and deontic logic (see e.g. [4, 27, 30, 31] ).  ...

Non-monotonic Reasoning in Deductive Argumentation [article]

Anthony Hunter
2018 arXiv   pre-print
However, the base logic does not need to be non-monotonic.  ...  Indeed, most proposals for structured argumentation use a monotonic base logic (e.g. some form of modus ponens with a rule-based language, or classical logic).  ...  So our primary aim in this paper is to investigate how non-monotonic reasoning arises in deductive argumentation, and how that differs from logics for non-monotonic reasoning.  ...

Rationality and maximal consistent sets for a fragment of ASPIC + without undercut

Jesse Heyninck, Christian Straßer
2020 Argument & Computation  
This generality comes at the price that, in their most general form, formalisms such as ASPIC + do not satisfy important rationality postulates, such as non-interference.  ...  Clearly, for a formal model of defeasible reasoning it is important to understand for which range of parameters the formalism (a) displays a behavior that adheres to common standards of consistency, logical  ...  Acknowledgements We would like to thank the anonymous reviewers of this manuscript for useful comments.  ...

Reasoning With and About Norms in Logical Argumentation [chapter]

Kees Van Berkel, Christian Strasser
2022 Frontiers in Artificial Intelligence and Applications  
Formal argumentation has proven to be a unifying framework for representing nonmonotonic logics.  ...  We prove soundness and completeness between DAC-instantiated argumentation frameworks and constrained Input/Output logics. We illustrate our approach in view of two deontic paradoxes.  ...  An ASPIC + -based approach yields the obligation to p with stable semantics since the argument for p from ( , p) is unchallenged.  ...

Prioritized norms in formal argumentation

Beishui Liao, Nir Oren, Leendert van der Torre, Serena Villata
2018 Journal of Logic and Computation  
To resolve conflicts among norms, various nonmonotonic formalisms can be used to perform prioritized normative reasoning.  ...  Meanwhile, formal argumentation provides a way to represent nonmonotonic logics. In this paper, we propose a representation of prioritized normative reasoning by argumentation.  ...  Acknowledgements The authors are grateful to the anonymous reviewers for their helpful comments. The research reported in this  ...

Enabling Reasoning with LegalRuleML [article]

Ho-Pun Lam, Mustafa Hashmi
2018 arXiv   pre-print
This paper presents an approach for transforming legal norms represented using LegalRuleML to a variant of Modal Defeasible Logic (and vice versa) such that a legal statement represented using LegalRuleML  ...  For instance, most of these formalisms do not provide features to capture the behavior of deontic effects, which is an important aspect in automated compliance checking.  ...  The Logical Framework Defeasible Logic (DL) (Nute 2001 ) is a rule-based skeptical approach to non-monotonic reasoning.  ...

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

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.  ...  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  ...  We have received funding from the European Union's H2020  ...

Sequent-Based Argumentation for Normative Reasoning [chapter]

Christian Straßer, Ofer Arieli
2014 Lecture Notes in Computer Science  
For this, we adopt a recently proposed framework for logical argumentation in which arguments are generated by a sequent calculus of a given base logic (see [1]), and use standard deontic logic as our  ...  In this paper we present an argumentative approach to normative reasoning. Special attention is paid to deontic conflicts, contraryto-duty and specificity cases.  ...  As a consequence, our consequence relations are non-monotonic.  ...

Towards AI Logic for Social Reasoning [article]

Huimin Dong, Réka Markovich, Leendert van der Torre
2021 arXiv   pre-print
In this paper, we discuss how an argumentation-based AI logic could be used also to formalize important aspects of social reasoning.  ...  Fourth, we discuss how to argue about the freedom to act for intelligent agents. Examples from social, legal and ethical reasoning highlight the challenges in developing social AI logic.  ...  In this sense, AI logics are non-monotonic logic [43] .  ...

Theory of Semi-Instantiation in Abstract Argumentation

As an example of a logic let us take intuitionisitc propositional logic H, with consequence ⊢ H we can have: holds Another example is 3-valued classical propositional logic with the Kleene truth table  ...  Let us ask ourselves a very simple question: Question. What is the added value of abstract argumentation networks over, say, classical propositional logic?  ...  This can also be defined not only for monotonic theories but also for non-monotonic theories which satisfy the restricted monotonicity rule, namely:∆| ∼Φ and ∆ + Φ| ∼Ψ ==> ∆| ∼Ψ.  ...

Sequent-based logical argumentation

Ofer Arieli, Christian Straßer
2015 Argument & Computation  
Altogether, we show that argumentation theory may benefit from incorporating proof theoretical techniques and that different non-classical formalisms may be used for backing up intended argumentation semantics  ...  This framework accommodates different languages and logics in which arguments may be represented, allows for a flexible and simple way of expressing and identifying arguments, supports a variety of attack  ...  • The incorporation of more complex forms of sequents, such as hypersequents (Avron 1987) or nested sequents (Brünnler 2010) , allows to express more sophisticated forms of argumentation, such as argumentation  ...
