Evidential and Practical Certainty,
Abstract
It is argued that there are significant advantages to using a tow-level framework for knowledge representation. It allows both what corresponds to default assumptions, based on high probability, and also it allows a way to abandon those defaults under special circumstances. The basic mechanism for determining membership in the lower level representation is a criterion of high probability relative to the evidence embodied in the upper level. Probabilities are also defined, in the same way, relative to the lower level, one those are the probabilities that are used in the computation of decisions.
