ABA 2013 - Special Session on Advances In Bipolarity Applied To Databases And Information Systems

Organizers: Allel Hadjali, Ludovic Liétardand and Henri Prade
In the very recent years, bipolar modeling of preferences and knowledge has attracted the interest of many researchers, especially, in Databases and Information Systems fields. The idea of bipolarity refers to the distinction between what is regarded as positive and what is regarded as negative. When bipolarity is encountered in preference representations: (i) negative preferences express what is (more or less, or completely) impossible, and by complementation, they specify flexible constraints restricting tolerated values ; (ii) positive preferences are less compulsory, and rather express wishes. Research issues in this area cover different aspects related, for instance, to modeling, merging, rank-ordering, learning, etc. This special session will be an exciting opportunity to exchange ideas and discuss recent results about bipolarity and/or its application in Databases and Information Systems fields.
