摘要：

This paper presents an extension of relational algebra suitable for the handling of bipolar concepts. The type of queries considered involves two parts: a first one which expresses a (possibly flexible) constraint, and a second one that corresponds to a (possibly flexible) wish. The framework considered is that of bipolar fuzzy relations where each tuple is associated with a pair of satisfaction degrees. (C) 2012 Elsevier Inc. All rights reserved.
