Topics of Interest

The scope of the workshop is intentionally broad and addresses all aspects of under-standing, modeling, computational handling, and application of preferences. In particular, we welcome original contributions to these areas and contributions that provide cross-fertilization between these fields, like e.g. the application of AI techniques to database queries. Furthermore, we highly appreciate applications of preferences, in particular for personalized database applications.
