HYDRO: Towards Non-Reversible Face De-Identification Using a High-Fidelity Hybrid Diffusion and Target-Oriented Approach

Felix Rosberg, Vitomir Štruc, Cristofer Englund +2

Target-oriented face de-identification models aim to anonymize the identity of a target individual across different images or video frames, such that the target can no longer be re…

MARLA: A Conceptual Scaffold for Regulatory Learning under the EU AI Act

Alessio Buscemi, Tom Deckenbrunnen, Imane Hmiddou +5

The EU AI Act positions regulation as part of the infrastructure for safe, trustworthy and market-ready innovation. Realising this ambition requires regulatory learning: the eviden…

A Modal Logic for Temporal and Jurisdictional Classifier Models

Cecilia Di Florio, Huimin Dong, Antonino Rotolo

Logic-based models can be used to build verification tools for machine learning classifiers employed in the legal field. ML classifiers predict the outcomes of new cases based on p…

Deontic Argumentation

Guido Governatori, Antonino Rotolo

We address the issue of defining a semantics for deontic argumentation that supports weak permission. Some recent results show that grounded semantics do not support weak permissio…

Foundations for Risk Assessment of AI in Protecting Fundamental Rights

Antonino Rotolo, Beatrice Ferrigno, Jose Miguel Angel Garcia Godinez +2

This chapter introduces a conceptual framework for qualitative risk assessment of AI, particularly in the context of the EU AI Act. The framework addresses the complexities of lega…

Judicial Permission

Guido Governatori, Antonino Rotolo

This paper examines the significance of weak permissions in criminal trials (\emph{judicial permission}). It introduces a dialogue game model to systematically address judicial per…

Rule-based Classifier Models

Cecilia Di Florio, Huimin Dong, Antonino Rotolo

We extend the formal framework of classifier models used in the legal domain. While the existing classifier framework characterises cases solely through the facts involved, legal r…

A Replica for our Democracies? On Using Digital Twins to Enhance Deliberative Democracy

Claudio Novelli, Javier Argota Sánchez-Vaquerizo, Dirk Helbing +2

Deliberative democracy depends on carefully designed institutional frameworks, such as participant selection, facilitation methods, and decision-making mechanisms, that shape how d…

When Precedents Clash

Cecilia Di Florio, Huimin Dong, Antonino Rotolo

Consistency of case bases is a way to avoid the problem of retrieving conflicting constraining precedents for new cases to be decided. However, in legal practice the consistency re…

Stable Normative Explanations: From Argumentation to Deontic Logic

Cecilia Di Florio, Guido Governatori, Antonino Rotolo +1

This paper examines how a notion of stable explanation developed elsewhere in Defeasible Logic can be expressed in the context of formal argumentation. With this done, we discuss t…

Modelling and Explaining Legal Case-based Reasoners through Classifiers

Xinghan Liu, Emiliano Lorini, Antonino Rotolo +1

This paper brings together two lines of research: factor-based models of case-based reasoning (CBR) and the logical specification of classifiers. Logical approaches to classifiers…

Deontic Meta-Rules

Francesco Olivieri, Guido Governatori, Matteo Cristani +2

The use of meta-rules in logic, i.e., rules whose content includes other rules, has recently gained attention in the setting of non-monotonic reasoning: a first logical formalisati…

Avoiding Pragmatic Oddity: A Bottom-up Defeasible Deontic Logic

Guido Governatori, Silvano Colombo Tosatto, Antonino Rotolo

This paper presents an extension of Defeasible Deontic Logic to deal with the Pragmatic Oddity problem. The logic applies three general principles: (1) the Pragmatic Oddity problem…

Is Free Choice Permission Admissible in Classical Deontic Logic?

Guido Governatori, Antonino Rotolo

In this paper, we explore how, and if, free choice permission (FCP) can be accepted when we consider deontic conflicts between certain types of permissions and obligations. As is w…

Dealing with Qualitative and Quantitative Features in Legal Domains

Maximiliano C. D. Budán, María Laura Cobo, Diego I. Martínez +1

In this work, we enrich a formalism for argumentation by including a formal characterization of features related to the knowledge, in order to capture proper reasoning in legal dom…

A Labelling Framework for Probabilistic Argumentation

Regis Riveret, Pietro Baroni, Yang Gao +3

The combination of argumentation and probability paves the way to new accounts of qualitative and quantitative uncertainty, thereby offering new theoretical and applicative opportu…

The Rationale behind the Concept of Goal

Guido Governatori, Francesco Olivieri, Simone Scannapieco +2

The paper proposes a fresh look at the concept of goal and advances that motivational attitudes like desire, goal and intention are just facets of the broader notion of (acceptable…

Strategic Argumentation is NP-Complete

Guido Governatori, Francesco Olivieri, Simone Scannapieco +2

In this paper we study the complexity of strategic argumentation for dialogue games. A dialogue game is a 2-player game where the parties play arguments. We show how to model dialo…

Computing Strong and Weak Permissions in Defeasible Logic

Guido Governatori, Francesco Olivieri, Antonino Rotolo +1

In this paper we propose an extension of Defeasible Logic to represent and compute three concepts of defeasible permission. In particular, we discuss different types of explicit pe…
