My research interests and activities
Research interests
My research concerns mainly knowledge representation and reasoning (KRR), especially non-monotonic reasoning (NMR). Some keywords:
- Formal Argumentation
- mainly abstract argumentation (Dung’s framework and its generalizations),
- deductive argumentation,
- argument-based negotiation,
- uncertainty in argumentation,
- argument strength,
- argumentation for explainable AI,
- argumentation for legal reasoning,
- Belief change (belief revision, belief merging). I’ve been particularly interested in the intersection of argumentation and belief change (this intersection was the topic of my Ph.D. thesis).
I am also interested in algorithmic solutions (mainly based on SAT) for hard problems:
- see CoQuiAAS and Crustabri for my work about this topic for abstract argumentation;
- more recently, resources allocation.
My recent and ongoing work also concerns the use of Large Language Models for extracting information from text, in particular legal argument mining.
