Hands on PROTÉGÉ for Ontology Construction and Query Retrieval in Context of Automobile Domain

This paper provides a detailed exposition of the concept of ontology, focusing on the processes and methodologies involved in its construction. The utilization of ontologies has played a significant role in the advancement of the Semantic Web. It is an expansion of the existing World Wide Web, characterized by the provision of well-defined meanings to information. This facilitates the translation of unstructured data into meaningful representations, thereby enabling effective collaboration between humans and computers. Ontology can be described as a compilation of a group of concepts, along with their corresponding definitions and interconnections, which are structured hierarchically and referred to as Taxonomy. Several ontology development tools are accessible, such as Hozo, DOML, and AltovaSemantic Works. Protégé, a commonly utilized ontology development editor, has been employed to define ontology concepts. In addition, it provides support for multiple ontology representation languages, such as OWL. The present study demonstrates the process of ontology development through the utilization of Protégé 3.4.1, with a specific focus on the domain of automobiles. A case study is presented to exemplify the application of this methodology.
