This paper introduces a qualitative ranking function that uses signed integers to describe the surprise associated with the occurrence of events. The measure introduced, kappa++, is based on the kappa calculus but differs from it in that its semantics enable an explicit representation of complements. As a result, the kappa++ is more capable of enforcing probability theory-like constraints to carry on reasoning.
