Abstract
The main objective of the procedure proposed in this paper is to use ontologies to convert a problem domain text description into an object model The object model of a system consists of objects identified from the text description and structural linkages corresponding to existing or established relationships The ontologies provide metadata schemas offering a controlled vocabulary of concepts At the center of both object models and ontologies are objects within a given problem domain The difference is that while the object model should contain explicitly shown structural dependencies between objects in a system including their properties relationships events and processes the ontologies are based on related terms only On the other hand the object model refers to the collections of concepts used to describe the generic characteristics of objects in objectoriented languages Because ontology is accepted as a formal explicit specification of a shared conceptualization we can naturally link ontologies with object models which represent a systemoriented map of related objects described as Abstract Data Types ADTs This paper addresses ontologies as a basis of a complete methodology for object modeling including available tools particularly CORPORUM OntoExtract and VisualText which can help the conversion process This paper describes how the developers can implement this methodology on the basis of an illustrative example
