| Abstract: | |
| An approach for extensible ontological model construction in a mediation
environment intended for heterogeneous information sources
integration in various subject domains is presented. A mediator
ontological language (MOL) may depend on a subject domain and is to be
defined at the mediator consolidation phase. On the other hand, for
different information sources different ontological models
(languages) can be used to define their own ontologies. Reversible
mapping of the source ontological models into MOL is needed for
informa-tion sources registration at the mediator. An approach for
such reversible mapping is demonstrated for a class of the Web
information sources. It is assumed that such sources apply the OWL ontological model.
A subset of the hybrid object-oriented and
semi-structured canonical mediator data model is used for the core of
MOL. Construction of a reversible mapping of OWL into an
extension of the core of MOL is presented in the paper. Such mapping
is a necessary prerequisite for contextualizing and registration of
information sources at the mediator. The mapping shows how extensible
MOL can be constructed. The approach proposed is oriented on digital
libraries where retrieval is focused on information content, rather
than on information entities.
