The past 25 years have seen many attempts to introduce defeasible-reasoning capabilities
into a description logic setting. Many, if not most, of these attempts are based on preferential …

Dealing with context dependent knowledge is a well-known area of study that roots in John

Abstract The Contextualized Knowledge Repository (CKR) framework has been proposed
as a description logics-based approach for contextualization of knowledge, a well-known …

The problem of representing and reasoning with context dependent knowledge has recently
gained interest in the area of description logics: among the several proposals, we consider …

Reasoning on defeasible knowledge is a topic of interest in the area of description logics, as
it is related to the need of representing exceptional instances in knowledge bases. In this …
