The Italian Conference on Computational Logic (CILC) is the annual meeting of the Italian Association for Logic Programming (GULP - Gruppo Ricercatori e Utenti Logic Programming).
Since its first edition, which was held in Genoa in 1986, the Conference has represented an important occasion for meeting and exchanging ideas and experiences between users, researchers, and developers working in the field of Computational Logic.
Over the years, the Conference organized by GULP has broadened its horizon from the specific field of logic programming to the more general one of Computational Logic, including for instance, declarative programming, constraint programming, and applications in various neighboring sectors, such as Artificial Intelligence.
The 39th Italian Conference on Computational Logic will be held in Rome at the National Research Council of Italy on 26-28 June 2024.
The Conference will feature presentations of invited speakers and contributed papers concerning all aspects of computational logic. The topics of interest for the conference are, but are not limited to, the following:
The Conference solicits two types of submissions:

ASP Chef is built around the notion of ASP recipe, a chain of ingredients combining computational tasks typical of ASP with other operations of data manipulation and visualization. All operations implement functions that map lists of answer sets to lists of answer sets, and have parameters to customize the mapping. For example, the Search Models operation combines the answer sets in input with an ASP program to obtain a new list of answer sets, and the Merge operation outputs an answer set representing all the answer sets in input. After around one year of development, ASP Chef now supports more than 80 operations originated from different research projects (among them, FAIR, PRODE, RADIOAMICA, SERICS, Tech4You). The tutorial starts with the basic usage of ASP Chef and moves to more advanced use cases such as the possibility to save and share recipes with GitHub, the available options for extending the supported operations, and the command line interpreter.
I graduated cum laude and obtained my Ph.D. at University of Calabria. Since February 2011 I work for Department of Mathematics and Computer Science of University of Calabria: two years as PostDoc, four years as Researcher, seven years as Associate Professor and since October 2023 I am Full Professor. I teach Secure Software Design and Cyber Offense and Defence.
I have conducted training and research periods in Vienna (2005, 2009, and 2015) and Oxford (2014). I gave invited seminars at the universities of Huddersfield (2014), Klagenfurt (2014), Potsdam (2016 and 2023), Helsinki (2017), Mindanao State University, and University of Science and Technology of Southern Philippines (2019). I was the speaker of more than 50 oral presentations at scientific conferences, some of them as keynote speaker (ICTCS & CILC 2017, ASPOCP 2018 and 2021, JELIA 2023, TAASP 2023) and invited speaker (AIxIA 2008 and 2017, ECAI 2012, IJCAI 2016 and 2017). I am the author of more than 120 scientific articles, including papers in top journals such as AIJ, JAIR, and TPLP, and top conferences such as IJCAI, AAAI, KR, and PODS. I am listed among the scientists with the highest impact in Elsevier's "science-wide author databases of standardized citation indicators" (v4, v5, v6).
I lead the LAIA lab (Laboratorio di Applicazioni dell'Intelligenza Artificiale, part of the SILA IR). I am co-PI of the PRIN project PRODE "Probabilistic Declarative Process Mining". I am involved in several projects, among them the PNRR project FAIR "Future AI Research"; the PNRR project Tech4You "Technologies for climate change adaptation and quality of life improvement"; the PNRR project SERICS "SEcurity and RIghts in the CyberSpace"; the POS projects CAL.HUB.RIA and RADIOAMICA; the STROKE 5.0 project.
I won several academic awards, among them Artificial Intelligence Award "Marco Somalvico" 2017 (AIxIA, Italian Association for Artificial Intelligence, best Italian young researchers in AI). honourable mention for my thesis by the European Coordinating Committee for Artificial Intelligence (ECCAI 2012); Italian best thesis in Artificial Intelligence award 2008 (AIxIA); ICLP 2015 Best Paper Award; RR 2015 Best Paper Award; ICLP 2016 Best Paper Award; LPNMR 2022 Best Paper Award; CILC 2023 Best Paper Award.
Current advances in Artificial Intelligence (AI) and Machine Learning (ML) have achieved unprecedented impact across research communities and industry. Nevertheless, serious concerns around trust, safety, interpretability and accountability in AI were raised by influential thinkers. Many identified the need for well-founded knowledge representation and reasoning to be integrated with ML systems. Neurosymbolic AI has been an active area of research for many years seeking to do just that, bringing together robust learning in neural networks with reasoning and explainability via symbolic representation and description. In this talk I will review the research in neurosymbolic AI and computation, and discuss how it can help shed light into the increasingly prominent role of safety, trust, interpretability and accountability in AI. AI has become the focus of large-scale research endeavours and has changed businesses. This led to an important debate about the impact of AI on education and society. It has been argued that the building of a rich AI system, semantically sound, explainable and ultimately trustworthy, will require a sound reasoning layer in combination with deep learning. Parallels have been drawn between Daniel Kahneman’s research on human reasoning and decision making and so-called AI systems 1 and 2. I will revisit early theoretical results of fundamental relevance to shaping the latest research, such as the proof that recurrent neural networks compute the semantics of logic programming. I will also seek to identify bottlenecks and the most promising technical directions for the sound representation of learning and reasoning in neural networks. I will conclude by discussing the key ingredients for sustainable AI going forward, identifying directions and challenges for the next decade of research in the field.

The advent of Large Language Models (LLMs) like GPT-4 represents a significant leap forward in the field of Artificial Intelligence, offering unprecedented capabilities in understanding, generating, and interacting with human language. This talk aims to demystify these complex systems, explaining their fundamental architecture, how they are trained on vast datasets, and the underlying technologies that enable their sophisticated processing abilities. We will explore the importance of LLMs, highlighting their role in driving innovation, enhancing productivity, and opening new avenues for human-computer interaction. However, with great power comes great responsibility, and LLMs are not without their limitations and challenges. This presentation will critically examine the inherent weaknesses of LLMs, such as biases in training data, the potential for generating misleading information, and ethical concerns. We will delve into real-world examples to illustrate these failures, offering a balanced perspective on the capabilities and limitations of these models. Finally, I will overview ongoing research in my group aimed at mitigating these shortcomings, including extracting facts from generated text and interconnecting them to the source text.
Disclaimer: 90% of this abstract was generated by GPT-4.

AI has become pervasive in recent years, but state-of-the-art approaches mostly neglect the need for AI systems to be contestable. Contestability is advocated by AI guidelines (e.g. by the OECD) and regulation of automated decision-making (e.g. GDPR). In contrast, there has been little attention in AI to suggest how contestability requirements can be met computationally. Contestability requires dynamic (human-machine or machine-machine) decision-making processes, whereas much of the current AI landscape is tailored to static AIs - thus the need to accommodate contestability will require a radical rethinking. In this talk I will argue that computational forms of contestable AI will require forms of explainability whereby machines and humans can interact, and that computational argumentation can support the needed interactive explainability for contestability.
