Abstract:

The information has always been a valuable patrimony for the information systems that every company tries to capitalize as much as possible. With the web, the amount of information is increased and several problems arise for instance for the safety of the exchanged data but also to the semantic heterogeneity: the same information is very often represented in different ways in different information systems. In this paper we present an architecture of interchange of data both within the same information system and among different information systems founded on the ontologies in order to overcome the problem list of the heterogeneity. Ontologies, today, they seem to be the best tool useful to resolve the problem of heterogeneity, but that has not now been exploited fully.
