Neuro-Symbolic AI for Compliance Checking of Electrical Control Panels

no code implementations17 May 2023 Vito Barbara, Massimo Guarascio, Nicola Leone, Giuseppe Manco, Alessandro Quarta, Francesco Ricca, Ettore Ritacco

In particular, assessing the compliance of a product with the relative schematic is a time-consuming and prone-to-error process.

A Formal Comparison between Datalog-based Languages for Stream Reasoning (extended version)

no code implementations26 Aug 2022 Nicola Leone, Marco Manna, Maria Concetta Morelli, Simona Perri

The paper investigates the relative expressiveness of two logic-based languages for reasoning over streams, namely LARS Programs -- the language of the Logic-based framework for Analytic Reasoning over Streams called LARS -- and LDSR -- the language of the recent extension of the I-DLV system for stream reasoning called I-DLV-sr.

Manipulation of Articulated Objects using Dual-arm Robots via Answer Set Programming

no code implementations2 Oct 2020 Riccardo Bertolucci, Alessio Capitanelli, Carmine Dodaro, Nicola Leone, Marco Maratea, Fulvio Mastrogiovanni, Mauro Vallati

We validate the overall framework in the extended scenario, thereby confirming the applicability of ASP also in more realistic Robotics settings, and showing the usefulness of macro actions for the robot-based manipulation of articulated objects.

A logic-based decision support system for the diagnosis of headache disorders according to the ICHD-3 international classification

no code implementations6 Aug 2020 Roberta Costabile, Gelsomina Catalano, Bernardo Cuteri, Maria Concetta Morelli, Nicola Leone, Marco Manna

Decision support systems play an important role in medical fields as they can augment clinicians to deal more efficiently and effectively with complex decision-making processes.

ASP-Core-2 Input Language Format

1 code implementation11 Nov 2019 Francesco Calimeri, Wolfgang Faber, Martin Gebser, Giovambattista Ianni, Roland Kaminski, Thomas Krennwallner, Nicola Leone, Marco Maratea, Francesco Ricca, Torsten Schaub

Standardization of solver input languages has been a main driver for the growth of several areas within knowledge representation and reasoning, fostering the exploitation in actual applications.

Precomputing Datalog evaluation plans in large-scale scenarios

no code implementations29 Jul 2019 Alessio Fiorentino, Nicola Leone, Marco Manna, Simona Perri, Jessica Zangari

With the more and more growing demand for semantic Web services over large databases, an efficient evaluation of Datalog queries is arousing a renewed interest among researchers and industry experts.

Enhancing magic sets with an application to ontological reasoning

1 code implementation19 Jul 2019 Mario Alviano, Nicola Leone, Pierfrancesco Veltri, Jessica Zangari

It turns out that the new version of magic sets is closed for Datalog programs with stratified negation and aggregations, which is very convenient to obtain efficient computation of the stable model of the rewritten program.

Negation

On the Computation of Paracoherent Answer Sets

no code implementations21 Jul 2017 Giovanni Amendola, Carmine Dodaro, Wolfgang Faber, Nicola Leone, Francesco Ricca

Answer Set Programming (ASP) is a well-established formalism for nonmonotonic reasoning.

Negation

Driving CDCL Search

no code implementations16 Nov 2016 Carmine Dodaro, Philip Gasteiger, Nicola Leone, Benjamin Musitsch, Francesco Ricca, Konstantin Schekotihin

The CDCL algorithm is the leading solution adopted by state-of-the-art solvers for SAT, SMT, ASP, and others.

Combining Answer Set Programming and Domain Heuristics for Solving Hard Industrial Problems (Application Paper)

1 code implementation2 Aug 2016 Carmine Dodaro, Philip Gasteiger, Nicola Leone, Benjamin Musitsch, Francesco Ricca, Kostyantyn Shchekotykhin

In this paper the combination of ASP and domain-specific heuristics is studied with the goal of effectively solving real-world problem instances of PUP and CCP.

Ontology-driven Information Extraction

no code implementations18 Dec 2015 Weronika T. Adrian, Nicola Leone, Marco Manna

Homogeneous unstructured data (HUD) are collections of unstructured documents that share common properties, such as similar layout, common file format, or common domain of values.

Table Recognition text annotation

Complexity and Compilation of GZ-Aggregates in Answer Set Programming

no code implementations14 Jul 2015 Mario Alviano, Nicola Leone

Gelfond and Zhang recently proposed a new stable model semantics based on Vicious Circle Principle in order to improve the interpretation of logic programs with aggregates.

Unfounded Sets and Well-Founded Semantics of Answer Set Programs with Aggregates

no code implementations18 Jan 2014 Mario Alviano, Francesco Calimeri, Wolfgang Faber, Nicola Leone, Simona Perri

As a consequence, a well-founded semantics for general LPA programs that allows for tractable computation is unlikely to exist, which justifies the restriction on LPAma programs.

The DLV System for Knowledge Representation and Reasoning

no code implementations4 Nov 2002 Nicola Leone, Gerald Pfeifer, Wolfgang Faber, Thomas Eiter, Georg Gottlob, Simona Perri, Francesco Scarcello

As for problem solving, we provide a formal definition of its kernel language, function-free disjunctive logic programs (also known as disjunctive datalog), extended by weak constraints, which are a powerful tool to express optimization problems.
