Using Ontologies to Create Object Model for Object-Oriented Software Engineering
Ontologies, (2007)Abstract
In this paper we introduce and discuss our approach to creating an object model from a problem domain text description asa basic deliverable of the analysis phase in Object-Oriented Software Engineering using ontologies. For this purpose we firstbriefly compare object models with ontologies. The object model of a system consists of objects, identified from the textdescription and structural linkages corresponding to existing or established relationships. The ontologies provide metadataschemas, offering a controlled vocabulary of concepts. At the center of both object models and ontologies are objects withina given problem domain. The both concepts are based on reusability using intensively libraries. The major difference is thatwhile the object model contains explicitly shown structural dependencies between objects in a system, including their properties,relationships and behavior, the ontologies are based on related terms (concepts) only. Because ontology is accepted as a formal,explicit specification of a shared conceptualization, we can naturally link ontologies with object models, which representa system-oriented map of related objects. To become usable programming entities these objects should be described as AbstractData Types (ADTs). This paper addresses ontologies as a basis of a complete methodology for object identification and theirmodeling as (converting to) ADTs, including procedures and available tools such as CORPORUM OntoExtract and VisualText, whichcan help the conversion process. This paper describes how the developers can implement this methodology on the base of anillustrative example.
