Based on an in-depth evaluation of existing approaches to this problem we discuss how ontologies are used to support the integration task. We evaluate and compare the languages used to represent the ontolo- gies and the use of mappings between ontologies as well as to connect

Computer systems which act intelligently need the ability to represent, utilize and reason about contexts and ontologies. Recently we have seen a number of projects devoted to the definition and usage of contexts as well as ontologies in intelligent KR systems. With the advent of the web and the ubiquitous connectivity it brings, contexts and ontologies have become a relevant notion also in other, more recent, applications. Many such applications, ...
