Abstract

This paper deals with the interpretation of database queries with preference conditions of the form "attribute is low (resp. medium, high)" in the situation where the user is not aware of the actual content of the database but still wants to retrieve the best possible answers (relatively to that content). An approach to the definition of the terms "low", "medium" and "high" in a contextual and relative manner is introduced.
