Ensuring trustworthy and ethical behaviour in intelligent logical agents

1 code implementation12 Feb 2024 Stefania Costantini

Autonomous Intelligent Agents are employed in many applications upon which the life and welfare of living beings and vital social functions may depend.

Epistemic Logic Programs: a study of some properties

no code implementations28 Sep 2023 Stefania Costantini, Andrea Formisano

Epistemic Logic Programs (ELPs), extend Answer Set Programming (ASP) with epistemic operators.

Proceedings 39th International Conference on Logic Programming

no code implementations28 Aug 2023 Enrico Pontelli, Stefania Costantini, Carmine Dodaro, Sarah Gaggl, Roberta Calegari, Artur d'Avila Garcez, Francesco Fabiano, Alessandra Mileo, Alessandra Russo, Francesca Toni

This volume contains the Technical Communications presented at the 39th International Conference on Logic Programming (ICLP 2023), held at Imperial College London, UK from July 9 to July 15, 2023.

Self-checking Logical Agents

no code implementations9 Nov 2021 Stefania Costantini

This paper presents a comprehensive framework for run-time self-checking of logical agents, by means of temporal axioms to be dynamically checked.

A Logic-based Multi-agent System for Ethical Monitoring and Evaluation of Dialogues

1 code implementation17 Sep 2021 Abeer Dyoub, Stefania Costantini, Ivan Letteri, Francesca A. Lisi

Dialogue Systems are tools designed for various practical purposes concerning human-machine interaction.

Multi-Context Systems: Dynamics and Evolution (Pre-Print of "Multi-context systems in dynamic environments")

no code implementations12 Jun 2021 Pedro Cabalar, Stefania Costantini, Giovanni De Gasperis, Andrea Formisano

Multi-Context Systems (MCS) model in Computational Logic distributed systems composed of heterogeneous sources, or "contexts", interacting via special rules called "bridge rules".

An application of Answer Set Programming in Distributed Architectures: ASP Microservices

no code implementations22 Sep 2020 Stefania Costantini, Lorenzo De Lauretis

We propose an approach to the definition of microservices with an Answer Set Programming (ASP) `core', where microservices are a successful abstraction for designing distributed applications as suites of independently deployable interacting components.

A Temporal Module for Logical Frameworks

no code implementations18 Sep 2019 Valentina Pitoni, Stefania Costantini

In this paper we define a time module suitable to add time to many logic representations of agents.

Towards Ethical Machines Via Logic Programming

no code implementations18 Sep 2019 Abeer Dyoub, Stefania Costantini, Francesca A. Lisi

Autonomous intelligent agents are playing increasingly important roles in our lives.

About epistemic negation and world views in Epistemic Logic Programs

no code implementations23 Jul 2019 Stefania Costantini

In this paper we consider Epistemic Logic Programs, which extend Answer Set Programming (ASP) with "epistemic operators" and "epistemic negation", and a recent approach to the semantics of such programs in terms of World Views.

Negation

Query Answering in Resource-Based Answer Set Semantics

no code implementations4 Aug 2016 Stefania Costantini, Andrea Formisano

In this paper, we propose a query-answering procedure reminiscent of Prolog for answer set programs under this extended semantics as an extension of XSB-resolution for logic programs with negation.

Committment-Based Data-Aware Multi-Agent-Contexts Systems

no code implementations8 Oct 2014 Stefania Costantini

In this paper, we propose the new approach of DACmMCMASs (Data-Aware Commitment-based managed Multi- Context MAS), so as to obtain a commitment-based first-order agent system which is able to interact with heterogeneous external information sources.

Towards Active Logic Programming

no code implementations21 Mar 2014 Stefania Costantini

In this paper we present the new logic programming language DALI, aimed at defining agents and agent systems.

Characterizing and computing stable models of logic programs: The non-stratified case

no code implementations21 Feb 2014 Gianpaolo Brignoli, Stefania Costantini, Ottavio D'Antona, Alessandro Provetti

Stable Logic Programming (SLP) is an emergent, alternative style of logic programming: each solution to a problem is represented by a stable model of a deductive database/function-free logic program encoding the problem itself.
