Model to describe multi-leved ontologies and their relations
El Hassan Abdelwahed · 2006
Abstract:- Within the last years, many ontologies are created and are accessible over the web. On the other hand, ontologies are used in many applications to explicit formalization of the conceptualization of the domain, but a given domain can be conceptualized through many different ontologies. Thus multiples ontologies connected by semantic relations emerge as a core question and became an essential issue of interoperability between distributed applications over the web. In this paper, we present a model and methodology for describing ontologies according to different levels of abstraction. The functional level contains generic ontologies and the domain level contains domain ontologies. The latter are described from the former by using a derivation process. The proposed formalism is based on an algebraic approach and it allows to capture the relations over different described ontologies.
