Bipolarity in preferences and intentions for more human consistent decision analysis and database querying

The concept of a bipolar query, meant as a database query that involves both mandatory and optional conditions, is discussed from the point of view of, first, flexible database querying and, second, some newer approaches to decision making involving affects and judgments, unconventional multicriteria decision making and the modeling of sophisticated user´s intentions and preferences of a positive and negative character. Aggregation of the matching degrees against the negative and positive conditions to derive an overall matching degree is considered in the fuzzy logic and possibilistic setting. Moreover, the use of a multiple valued logic based formalism for the representation of positive and negative desires in the context of intention modeling is advocated.
