The accurate and easy representation of users' preferences in information engineering systems becomes an important issue. Possibility theory provides a generic framework for the qualitative representation of preferences, where several equivalent information formats co- exist (distribution, logical bases, conditionals, graphical networks). Moreover, a bipolar representation distinguishing between positive and negative preferences has been developed in this setting. The paper offers a comprehensive survey of these representation issues.
