EXISTENTIAL DEPENDENCY DRIVEN APPROACH FOR EXTRACTING VIEWS FROM DOMAIN ONTOLOGY

Designing ontologies in modular way is generally considered as a good practice. The goal of ontology modularization is to obtain a module or a set of modules from an ontology, which fit the requirements of a particular application or a particular scenario. In this paper we describe an approach for extracting ontology views using existential dependency (ED) from OWL domain ontology. The first step of our approach consists of transforming OWL file ontology to UML class diagram by reverse engineering process. The next step is transformation of UML class diagram to the G-M foundational ontology relations (which has been represented in UML as profile) enriched with existential dependency. The extraction process based on ED could provide a coherent fragment of an ontology parts together with transitive closure of dependant parts.
