Abstract

A possible worlds semantics is suggested for a broad class of nonmonotonic inference relations, including not only traditional skeptical ones, but also credulous and contraction inference. The semantics could be used to provide a canonical framework for studying and comparing different kinds of nonmonotonic inference.
