Montréal, Québec, Canada
The ISC 2026 Summer School - Knowledge, reasoning, and decision-making will be held (in english) in hybrid mode, both online and in person.
9 school days spread over 3 weeks : from May 27 to June 10, 2026.
The Summer school will consist of a series of 36 talks, 9 plenary sessions (one per day), and two poster sessions on topics covered during the summer school.
The event is organized around five central themes in the field:

________
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).
