Abstract

We present a general framework for default logics, which encompasses most of the existing variants of default logic. It allows us to compare those variants from a knowledge representation point of view. We then exploit this framework to generalize Brewka's work on cumulative default logic, and to give an operational definition of extensions. Proof theoretical and semantical aspects are investigated.

This work was partially supported by the Esprit — BRA project DRUMS.

Work by the second author was partially performed during his stay at the Queen Mary and Westfield College, London, United Kingdom.

The authors wish to thank DRUMS people for their support. Especially, J. Mengin wishes to thank Mike Clarke for his support, and Mike Hopkins and Nick Wilson for fruitful discussions.
