# Possibilistic and Standard Probabilistic Semantics of Conditional Knowledge Bases

@inproceedings{Benferhat1999PossibilisticAS, title={Possibilistic and Standard Probabilistic Semantics of Conditional Knowledge Bases}, author={S. Benferhat and D. Dubois and H. Prade}, booktitle={J. Log. Comput.}, year={1999} }

The authors have proposed in their previous works to view a set of default pieces of information of the form, "generally, from αi deduce βi" as the family of possibility distributions satisfying constraints expressing that the situations where αiΛβi is true are more possible than the situations where αiΛ¬βi is true. A representation theorem in terms of this semantics, for default reasoning obeying the System P of postulates proposed by Kraus, Lehmann and Magidor, has been obtained. This paper… Expand
