Keeping Secrets in Possibilistic Knowledge Bases with Necessity-Valued Privacy Policies
Controlled Query Evaluation (CQE) is a logical framework for the protection of secrets in databases. In this article, we extend the CQE framework to possibilistic logic: knowledge ...

Reasoning with multiple-source information in a possibilistic logic framework
This paper addresses the problem of merging uncertain information in the framework of possibilistic logic. It presents several syntactic combination rules to merge possibilistic k...

Extending uncertainty formalisms to linear constraints and other complex formalisms
Linear constraints occur naturally in many reasoning problems and the information that they represent is often uncertain. There is a difficulty in applying AI uncertainty formalis...

A logic programming framework for possibilistic argumentation: Formalization and logical properties
In the last decade defeasible argumentation frameworks have evolved to become a sound setting to formalize commonsense, qualitative reasoning. The logic programming paradigm has s...

Using Arguments for Making Decisions: A Possibilistic Logic Approach
Humans currently use arguments for explaining choices which are already made, or for evaluating potential choices. Each potential choice has usually pros and cons of various stren...

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 t...

A Possibilistic Extension of Description Logics
Possibilistic logic provides a convenient tool for dealing with inconsistency and handling uncertainty. In this paper, we propose possibilistic description logics (DLs) as an exten...

A Semantic Approach for Iterated Revision in Possibilistic Logic
In this paper, we propose a new approach for iterated revision in possibilistic logic by applying a one-step revision operator. We first argue that the set of KM postulates for re...

Updating of a Possibilistic Knowledge Base by Crisp or Fuzzy Transition Rules
In this paper, partial knowledge about the possible transitions which can take place in a dynamical environment is represented by a set of pairs of propositional formulae, with th...
