Fusi on of Possi bilistic Knowl edge Base s from a Postul ate Point of View
Salem Benferhat, Souhila Kaci · 2015
This paper proposes a postulate-based analysis of the fusion of possibilistic logic bases which are made of pieces of information expressing knowledge associated with certainty degrees. We propose two main sets of postulates: one focuses only on plausible conclusions, while the other considers both plausible conclusions and the certainty degrees associated with them. For each rational postulate, the class of operators that satis-fies it is identified. The existence of weights associated with the pieces of information considerably enriches the postulates-based analysis, and leads to a refined classi-fication of combination operators.
