Merging Information Under Constraints: A Logical Framework
TL;DR: The paper considers the problem of merging several belief bases in the presence of integrity constraints and proposes a logical characterization of operators having a majority behaviour or a consensual one and a representation theorem in terms of pre-orders on interpretations is given.
Journal ArticleDOI
DA 2 merging operators
TL;DR: A new framework for propositional merging is presented and it is shown that (under very weak assumptions) query entailment from merged bases is "only" at the first level of the polynomial hierarchy when any of the DA2 operators is used.

Sylvie Coste-Marquis,Caroline Devred,Sébastien Konieczny,Marie-Christine Lagasquie-Schiex,Pierre Marquis +4 more
TL;DR: A general framework for merging argumentation systems from Dung's theory of argumentation is presented and voting is used on the selected extensions of the resulting systems so as to characterize the acceptable arguments at the group level.
Journal ArticleDOI
Logic Based Merging
TL;DR: The relationship between merging, revision, update and confluence, and some links between belief merging and social choice theory are discussed, and the main generalizations of these works in other logical frameworks are mentioned.
