From semantic to syntactic approaches to information combination in possibilistic logic. (English) Zbl 0898.68079

Bouchon-Meunier, Bernadette (ed.), Aggregation and fusion of imperfect information. Heidelberg: Physica-Verlag. Stud. Fuzziness Soft Comput. 12, 141-161 (1998).
Summary: This paper proposes syntactic combination rules for merging uncertain propositional knowledge bases provided by different sources of information, in the framework of possibilistic logic. These rules are the counterparts of combination rules which can be applied to the possibility distributions (defined on the set of possible worlds), which represent the semantics of each propositional knowledge base. Combination modes taking into account the levels of conflict, the relative reliability of the sources, or having reinforcement effects are considered.
