Projects

• Principal Investigator of the PRIN project DISTORT - Dynamic Disinformation Networks: Where is the Truth?, duration:24 months. The aim of the DISTORT project aims at delivering logic-based frameworks, equipped with explainable AI tools, for the early identification of fake news stories. In particular, the main objective is to help social media users in giving a better sense to inconsistencies about news circulating on social media, thus helping in solving the problem of disinformation diffusion.
• Coordinator for the University of Calabria research unit of the PRIN project HypeKG - Hybrid Prediction and Explanation with Knowledge Graphs. CUP: H53D2300370 0006, duration:24 months. The aim of the HypeKG project is the deliver of hybrid semantic-based explainable AI methods grounded on KGs. It builds upon: 1) a semantic-driven learning framework; 2) an explanation component. Leveraging the semantic of nodes/edges of a KG and underlying ontological knowledge (e.g., a schema) allows incorporating fine-grained semantic information into state-of-the-art numeric AI models designed to learn from graphs.
• Coordinator for the University of Calabria research unit of the POR project Explora Process. Started on 1st September 2017, duration:24 months. The objective of the project was the definition and implementation of a platform able to combine the traditional techniques of Process Analytics, Process Discovery, Process Mining, with the sophisticated algorithms of the Explora Text suite for semantic analysis, in order to obtain a “Semantic Process Analytics” platform. The "Explora Process" platform provides an integrated environment of process mining algorithms to analyze logs whose events can be classified with respect to a reference ontology, both manually or using, as a semi-automatic support, existing document classification tools.
