We study the problem of evolution for Knowledge Bases (KBs) expressed in Description
Logics (DLs) of the DL− Lite family. DL− Lite is at the basis of OWL 2 QL, one of the tractable …

Abstract Description logic Knowledge and Action Bases (KAB) are a mechanism for
providing both a semantically rich representation of the information on the domain of interest …

This paper provides a concise overview of the literature on inconsistency handling for
ontology-mediated query answering, a topic which has grown into an active area of research …

Ontology-mediated query answering (OMQA) is a recent approach to data access in which
conceptual knowledge provided by an ontology is exploited when querying incomplete data …

Evolution of Knowledge Bases (KBs) expressed in Description Logics (DLs) has gained a lot
of attention lately. Recent studies on the topic have mostly focused on so-called model …

We investigate the problem whether two ALC ontologies are indistinguishable (or
inseparable) by means of queries in a given signature, which is fundamental for ontology …

In description logic (DL), ABoxes are used for describing the state of affairs in an application
domain. We consider the problem of updating ABoxes when the state changes, assuming …
