Research
My research is related to information modeling. I use logics (classical and modal logics) and Belief Function Theory for:
- Modelling Opinion diffusion in networks of agents,
- Information fusion, information evaluation, reasoning with reported information,
- Logical approach to Belief Function Theory,
- Reasoning with Inconsistency, information base updates, consistency restoration,
- Normative Reasoning: Normative conflicts, Contrary-To-Duties, Collective obligations, regulation consistency, regulation completeness,
- Multi-agents: Reasoning with Goals, Preferences, Ability, Actions, Relevant information, cooperative agents.
