Designing the Ontology of the Military History Domain of the Iran-Iraq War

The purpose of this applied research is to design the ontology of military history domain of the Iran-Iraq war, in order to represent the sources of this domain. No specialized tools such as thesaurus or ontology have been designed to organize information in the Iran-Iraq war domain. To meet the information needs of researchers in this domain, we need representation of concepts in this domain; And since ontology is currently the most accurate tool available, this tool has been designed in this research. In this study, the content analysis method and domain analysis approach were used to extract the concepts and relationships between them; and Noy and McGuinness (2001) seven-way method were used to design ontology in a manual process. The research community is all written sources in the category of military history of the Iran-Iraq war. Sampling was done purposefully and 18 volumes of books from the category of military history of the Iran-Iraq war, available in the specialized library of the Hozeh Honari, were selected to analyze and extract key concepts and relations. After the initial study and extraction of key concepts and relationships, in order to confirm the accuracy of the extracted items, the opinion of military experts in this domain was applied in the research and the final approval of the experts was received; and Protégé 5.5.0 software was used to formalize these concepts. Finally, the ontology of the military history of the Iran-Iraq war was designed, with 880 axiom, 54 classes, 76 Individuals, 32 object property, 24 data type property, and 2 annotation data type properties. The main classes of this ontology include: military strategy with 11 subclasses, military operations with 11 subclasses, commanders with 5 subclasses, military organization with 17 subclasses, and war support with 5 subclasses. Designed ontology, in addition to representing concepts and semantic relationships in the domain of military history of the Iran-Iraq war, can also be used to improve information retrieval in the process of organizing and Query expansion in storage and retrieval systems. This representation provides an overview of the military history of the Iran-Iraq war to researchers and scholars, and can also be used as a tool for organizing war resources.
