Nowadays, more and more artificial agents integrate emotional abilities, for different purposes: expressivity, adaptability,
believability... Designers mainly use Ortony et al.’s typology of emotions, that provides a formalization of twenty-two emotions
based on psychological theories. But most of them restrain their agents to a few emotions among these twenty-two ones, and
are more or less faithful to their definition. In this paper we propose to extend standard BDI (belief, desire, intention)
logics to account for more emotions while trying to respect their definitions as exactly as possible.
A preliminary version of this work has been published in the ECAI worshop AITaMI’06. The authors would like to thank the AIMSA
