On a Graded Inclusion of Bipolar Fuzzy Relations

Ludovic Liétard, Olivier Pivert, Daniel Rocacher
This paper deals with database fuzzy queries in the context where the fuzzy preference conditions involved are of a bipolar nature (the first pole corresponding to a constraint, the second to a wish). More precisely, we consider queries where an inclusion-based condition comes into play (a typical example...

Distance to bipolar information from morphological dilation

Isabelle Bloch, Jamal Atif
In this paper we propose definitions of distances to bipolar information. This notion is important to find a solution that matches bipolar queries, to exhibit recommendations satisfying preferences of an agent while respecting her constraints, to find an agreement between several agents. All these situations...

On various forms of bipolarity in flexible querying

Didier Dubois, Henri Prade
The paper discusses the modeling of ''if possible" in requirements of the form ''A and if possible B". We distinguish between two types of understanding: either i) A and B are requirements of the same nature and are viewed as constraints with different levels of priority, or ii) they are of different...
