In the last decades, qualitative approaches to probabilistic uncertainty are receiving wider and wider attention. We propose a new characterization of some of the most adopted partial preference orders by providing an uniform axiomatic treatment of a variety of qualitative uncertainty notions. To this aim we prove a representation result that connects qualitative notions of partial uncertainty to their numerical counterparts. We describe an executable speci¯cation, in the declarative frame-work of Answer Set Programming, that constitutes the core engine for qualitative management of uncertainty. Some basic reasoning tasks are also identified.

Abstract
In the last decades, qualitative approaches to probabilistic uncertainty are receiving wider and wider attention. We propose a new characterization of some of the most adopted partial preference orders by providing an uniform axiomatic treatment of a variety of qualitative uncertainty notions. To this aim we prove a representation result that connects qualitative notions of partial uncertainty to their numerical counterparts. We describe an executable speci¯cation, in the declarative frame-work of Answer Set Programming, that constitutes the core engine for qualitative management of uncertainty. Some basic reasoning tasks are also identified.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
