Abstract
: We present JZBR, an extension of Spohn's iterated revision methodology which allows the handling of new information expressed by conditional ranking measure constraints. This is achieved by generalizing a canonical ranking construction technique originally developed for nonmonotonic entailment, notably system JZ. JZBR exploits the structure of the evidence base and is a robust relative of semi-qualitative cross entropy minimization.
