Abstract: Topoi are graudal inference rules, often used by experts in several problem classes: they can be exploited at various phases of a knowledge-based system life cycle. They can be studied at the two levels distinguished by Newell: the knowledge level and the symbol level. Some knowledge elicitation techniques such as KADS and KOD can be exploited in order to facilitate the acquisition of topoi. At the symbol level, different representations and implementations of topoi can be proposed and topoi can be formalized through several qualitatvie physics formalisms.
Keywords: knowledge acquisition, topoi elicitation, gradual inference, qualitative physics.
