Handling preferences in our daily lives is far from being an easy problem. We always hesitate when faced with a choice. Preferences guide our decisions from the simplest (which flavor of ice cream do you prefer?) to the most complex (what is the best investment?). We present our contributions in this area over the last six years. We promote “simple” languages for preference representation in order to allow a better expressiveness when specifying preferences. We also revisit some domains (argumentation, multi-criteria aggregation, database queries, question-answer systems, negotiation), where preferences play an important role, and show how they can benefit from our compact languages for preference representation.
