On the α-Conjunctions for Combining Belief Functions
The α-conjunctions basically represent the set of associative, commutative and linear operators for belief functions with the vacuous belief function as neutral element. Besides, they include as particular case the unnormalized Dempster’s rule. They are thus particularly interesting from a formal standpoint. However, they suffer from a main limitation: they lack a clear interpretation in general. In this paper, an interpretation for these combination rules is proposed, based on a new framework that allows the integration of meta-knowledge on the various forms of lack of truthfulness of the information sources.
