Following the Preference-Aversion (PA) model, previously introduced for identifying the subjective cognitive state for some decision situation; here, we explore a methodology for learning relevance degrees over the complete system of alternatives. In this way it is possible to identify in a quick way, the pieces of information that are more important for solving a given decision problem.spabook parthttps//doi.org/10.1007/978-3-642-37832-4_11http://link.springer.com/chapter/10.1007%2F978-3-642-37832-4_11restricted access510.5Preference structuresPeference-aversionRelevanceLógica simbólica y matemática (Matemáticas)1102.14 Lógica Simbólica
