Abstract

This paper deals with the evaluation of database preference queries in the framework of a preference model based on the notion of outranking. It describes an efficient technique that involves a pre-filtering step, whose aim is to limit the number of pairwise tuple comparisons necessary to determine the best answers to a query.
