This paper proposes a method of nonmonotonic theory change.
We first introduce a new form of abduction that can account for
observations in nonmonotonic situation. Then we provide a framework of
autoepistemic update, which describes nonmonotonic theory change
through the extended abductive framework.
The proposed update semantics is fairly general and provides
a unified framework for various update semantics such as first-order
update, view update of databases, and contradiction removal of
