Domain-Based Ontology Architecture

Abstract

Abstract-Ontologies are used for enhancement of explicit semantic information of data sources. We can establish a consensus between communities and resolve semantic heterogeneity conflicts between data sources through ontology. The reason ontologies are becoming so popular is in large part due to what they promise: a shared and common understanding of some domain that can be communicated between people and application systems. The creation of the ontology is a major issue in use of ontology. In order to create an ontology we need to extract all detailed specifications from the domain conceptualization, modeling these specifications based on a data model and formalizing these based on a formal language. Most ontologies are related to a specific domain area (such as university, music, movie, and so on) and thhee use of a particular vocabulary related to the domain area. We call these ontologies as domain-based ontology. In this paper we introduce a model for representing of domain-based ontologies. Subsequently we build an University ontology as a domainbased ontology, based on our proposed model. Finally we propose domain-based ontology architecture as an efficient approach in ontology-based data integration.
