A Comparison of Two Evidential Reasoning Schemes

[1] advocate the use of Dempster-Shafer (0-5) theory in evidence-gathering process. It is stated that they are unaware of any formal model which could allow inexact reasoning at whatever level of abstraction. [2] later shows how evidential reasoning can be conducted in the same hypolhesis space using a Bayesian model. The purpose of this note is to examine the difference of theses two schemes, and to point out certain inconsistencies of this Bayesian model with the motives behind the use of D-S model.
