What experts deny, novices must understand
Abstract
We consider the problem of representing the denial of
default information. We show that such denials are important parts
of commonsense reasoning. Moreover, their representation is not a
simple matter of negating traditional representations of default
information. We have found a solution by separating default information
into use and trend portions. This approach may also afford a more
compact way to represent defaults in general.
