On the transformation between possibilistic logic bases and possibilistic causal networks
Possibilistic logic bases and possibilistic graphs are two different frameworks of interest for representing knowledge. The former ranks the pieces of knowledge (expressed by logical formulas) according to their level of certainty, while the latter exhibits relationships between variables. The two types of representation are semantically equivalent when they lead to the same possibility distrib...

Possibilistic logic bases and possibilistic graphs are two different frameworks of interest for representing knowledge. The former stratifies the pieces of knowledge (expressed by logical formulas) accor?i�g to their level of certainty, while the latter exhibits relationships between variables. The two types of representations are semantically equivalent when they lead to the same possibility d...
متن کاملProduct-based Causal Networks and Quantitative Possibilistic Bases
In possibility theory, there are two kinds of possibilistic causal networks depending if possibilistic conditioning is based on the minimum or on the product operator. Similarly there are also two kinds of possibilistic logic: standard (min-based) possibilistic logic and quantitative (product-based) possibilistic logic. Recently, several equivalent transformations between standard possibilistic...
متن کاملGraphical readings of possibilistic logic bases
Possibility theory offers either a qualitative, or a numerical framework for representing uncertainty, in terms of dual measures of pos sibility and necessity. This leads to the ex istence of two kinds of possibilistic causal graphs where the conditioning is either based on the minimum, or on the product opera tor. Benferhat et al. [3] have investigated the connections between min-based grap...
متن کاملOn the Relationship Between Qualitative Choice Logic and Possibilistic Logic
Qualitative choice logic (QCL) is a propositional logic for representing prioritized alternatives. The logic adds to classical propositional logic a new connective called ordered disjunction: A~×B intuitively means: if possible A, but if A is not possible then at least B. QCL inference is obtained by defining a preference relation between interpretations of a propositional language. This paper ...
