Graphical readings of possibilistic logic bases

چکیده
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 graphs and possibilistic logic bases (made of classi cal formulas weighted in terms of certainty ). This paper deals with a more difficult issue: the product-based graphical representation of possibilistic bases, which provides an easy structural reading of possibilistic bases.

Product-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 کاملNew Graphical Model for Computing Optimistic Decisions in Possibility Theory Framework
This paper first proposes a new graphical model for decision making under uncertainty based on min-based possibilistic networks. A decision problem under uncertainty is described by means of two distinct min-based possibilistic Computing Optimistic Decisions 1039 networks: the first one expresses agent’s knowledge while the second one encodes agent’s preferences representing a qualitative utili...
متن کاملOn 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...
متن کاملInterval-Based Possibilistic Logic
Possibilistic logic is a well-known framework for dealing with uncertainty and reasoning under inconsistent knowledge bases. Standard possibilistic logic expressions are propositional logic formulas associated with positive real degrees belonging to [0,1]. However, in practice it may be difficult for an expert to provide exact degrees associated with formulas of a knowledge base. This paper pro...
متن کاملManaging Inconsistent Possibilistic Knowledge Bases by An Argumentation Approach
Inconsistent knowledge bases usually are regarded as an epistemic hell that have to be avoided at all costs. However, many times it is di cult or impossible to stay away of managing inconsistent knowledge bases. In this paper, we introduce an argumentation-based approach in order to manage inconsistent possibilistic knowledge bases. This approach will be exible enough for managing inconsistent ...
