Abstract
Many theoretical studies have been made of default and exception handling but few of them can be implemented in real applications because of the hard complexity of related algorithms. However users of knowledge represention systems want the possibility expressing default informations and exceptions. We have developed KDEX, a KL-ONE-like with default and exception handling, but we have defined constraints of construction to have polynomial inheritance algorithms. In this paper, we present the default exclusion link and its interpretation in a subset of default logic (we use a “free semi-normal” default) to show the soundness of its semantics and to justify the results given by our inheritance algorithms.
