________

 

Knowledge plays a crucial role in effective decision-making. This is why humans devote a significant portion of their cognitive activity to reasoning and decision-making, mobilizing and transforming their knowledge through both implicit and explicit reasoning strategies. Thus, recent advances in computer science and artificial intelligence are now significantly expanding these human capabilities by offering new tools for knowledge representation, reasoning modeling, and decision support.

The 2026 summer school aims to present several major areas of contemporary research on knowledge, reasoning, and decision-making, adopting a resolutely interdisciplinary perspective that draws on cognitive science, philosophy, psychology, linguistics, logic, and artificial intelligence. 

Students and researchers can register for credits or a training certificate (pricing varies according to status).

Find out what some of the world’s leading researchers in this topic have to say.
