    • found: Theory of evidence WWW home page, Sept. 16, 2002(The Dempster-Shafer theory of evidence has been introduced in the late Seventies by Glenn Shafer as a way of representing epistemic knowledge, starting from a sequence of seminal works of Arthur Dempster, Shafer's advisor. In this formalism the best representation of chance is a belief function (b.f.) rather than a Bayesian mass distribution. They assign probability values to sets of possibilities rather than single events: their appeal rests on the fact they naturally encode evidence in favor to propositions. The theory embraces the familiar idea of assigning numbers between 0 and 1 to indicate this degrees of support but, instead of focusing on how these numbers are determined, it concerns the combination of degrees of belief)
