Possibility theory in information fusion (NMR 2002)
Résumé
Possibility theory and the body of aggregation operations from fuzzy set theory provide some tools to address the problem of merging information coming from several sources. Possibility theory is a representation framework that can model various kinds of information items: numbers,intervals, consonant random sets, special kind of probability families, as well as linguistic information, and uncertain formulae in logical settings. "Me Possibilistic approach to fusion is general enough to encompass logical modes of combination (conjunctive and disjuntive) as well as fusion modes used in statistics. This general framework allows to import inconsistency handling methods, inherited from logic, into numerical fusion problems. The approach applies to sensor fusion, aggregation of expert opinions as well as the merging of databases especially in case of poor, qualitative information.
