G. Primiero, D. Ceolin, F. Doneda, A computational model for assessing experts’ trustworthiness, in Journal of Experimental and Theoretical Artificial Intelligence

We introduce an algorithmic model for automatically generating a dynamic trustworthiness hierarchy among information sources based on several parameters, including fact-checking. The method is novel and significant, especially in two respects: first, the generated hierarchy represents a helpful tool for laypeople to navigate experts’ debates; second, it also allows to identify and overcome biases generated by intuitive rankings held by agents at the beginning of the debates.

On the Foundations of Computing (OUP, 2019) Commentaries in Axiomathes – Global Philosophy (Springer)

They say that no publicity is bad publicity. This might thus apply also to critical analyses of my book On the Foundations of Computing (OUP 2019). Jokes aside, I am very thankful to a number of colleagues who have invested their time to express their thoughts (some critical, some praising) on specific topics touched upon in my book. These have appeared as articles in the Journal Axiomathes – Global Philosophy (Springer). The list is:

I wish to thank all authors and I hope to provide soon an articulated reply to their comments.

Research Meetings in 2023

2023 is shaping up to be a nice year to present current research and meet again with many colleagues working at the intersection of Logic, AI and Philosophy of Computing. Here a list of current commitments to research events:

This list is yet incomplete, stay tuned.

BRIO 2022 Summary.

BRIO is the MUR funded project on BIAS, RISK and Opacity in AI which I am leading as Principal Investigator. It officially started only in June 2022, but we already have done quite some work:

We are currently hiring a new post-doc. For all other updates visit this page.

A better digital garden for 2023.

This is the first of a new series of notes posted to my professional website straightforward from my digital garden based on #obsidian. I will try maintaining a more constant presence on the News section of my website through this new method. Good digital gardening to everyone in 2023.

New Research Project funded by MUR

The Ministry of University and Research has funded the 3-year research project “BRIO – BIAS, RISK, OPACITY in AI: design, verification and development of Trustworthy AI.” under the PRIN Scheme (Project no. 2020SSKZ7R).

I will lead the research consortium which includes researchers from the Politecnico di Milano,  Università degli Studi di Genova, Istituto di Scienze e Tecnologia della Cognizione CNR Trento, and Università degli Studi Napoli.

Info and updates will be made available on the website





Following several requests, the deadline for submission to the Journal of Logic and Computation Special Issue on Reasoning about Social Networks has been
extended one last time to *February 15th, 2021*. Papers submitted earlier will be handled as they come.


CFP: Special Issue on Reasoning about Social Networks, Journal of Logic and Computation

Following a successful workshop at ECAI2020 ( we invite submissions for a Special Issue on Reasoning about Social Networks in the Journal of Logic and Computation.


The special issue focuses on the issues of information spread in a social networks of natural and artificial agents, as studied by the emerging interdisciplinary field of multi-agent systems, logic and social network analysis. The topics of the workshop include but are not limited to:

•Logic based models of social networks phenomena
•Epistemic models on graphs
•Strategic behaviour in opinion diffusion
•Computational issues in opinion diffusion
•Computational Trust
•Collective information distortions and how to prevent them
•Model checking and verification of social network phenomena

All papers will be peer reviewed according to the standards of the Journal. Authors of submissions might also be asked to review a paper.

Submission details: Submissions are to be sent to all the guest editors, written in English and formatted in LaTeX, article documentclass, up to 20 pages, bibliographical references excluded. Please communicate with the editors your interest to submit.
