Abstract

A crucial problem in database querying is how to devise a query to best reflect the very intentions and preferences of the user. A new line of research in this area aims at taking into account the polarity of preferences what should considerably enhance the functionality and usefulness of flexible database querying systems. Bipolar queries constitute an important concept in this area. They are meant here, in general, as queries involving negative and positive information. In a special, promising interpretation they can be viewed in terms of necessary and possible conditions. The purpose of this paper is to critically analyze, recast in a unified perspective and clarify with respect to conceptual, algorithmic and implementation related aspects of various ways to deal with bipolarity. This should open new perspectives for research and commercial applications of bipolar and related queries which should provide more comprehensive, enhanced and more human consistent querying capabilities.
