Comparaison informationnelle de capacités qualitatives


Capacities are monotonically increasing set functions. They are said to be qualitative when they range on a finite linearly ordered scale. This paper pursues a parallel between qualitative capacities and the quantitative setting of belief functions. The qualitative setting appears to be as rich as the quantitative one, but qualitative counterparts of belief function notions do not always have the same meaning and/or behavior as in the quantitative case. The paper especially focuses on the comparison of qualitative capacities in terms of information content.
