Ontology evolution aims at maintaining an ontology up to date with respect to changes in the
domain that it models or novel requirements of information systems that it enables. The …

Ontologies play a key role in the advent of the Semantic Web. An important problem when
dealing with ontologies is the modification of an existing ontology in response to a certain …

With the advent of Semantic Web languages such as OWL (Web Ontology Language), the
expressive Description Logic [special characters omitted] is exposed to a wider audience of …

Ontology-based data management aims at accessing and using data by means of an
ontology, ie, a conceptual representation of the domain of interest in the underlying …

We develop a formal framework for comparing different versions of ontologies, and apply it
to ontologies formulated in terms of DL-Lite, a family of 'lightweight'description logics …

Information semantics and semantic interoperability among applications, systems, and
services are mostly based on ontology. Its increase usage in Information Systems and …

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 …

The ability to deal with inconsistencies and to evaluate the impact of possible solutions for
resolving inconsistencies are of the utmost importance in real world ontology applications …

To support the reuse and combination of ontologies in Semantic Web applications, it is often
necessary to obtain smaller ontologies from existing larger ontologies. In particular …
