Ontologies in Various Domains: A New Perspective of Ideas

The term ontology came from two Greek words i.e., “Onto” and “logos”. It denotes “study or knowledge about everything that actually exists”. Philosophers defined the word “Ontology” in their own way. It is discipline of philosophy [1] that deals with structures of things, events, processes, and relations in every aspect of reality. In recent years, research in multidisciplinary fields has exploded in various sectors or domain. “Ontology” term from philosophy was adapted and repurposed to fit the needs of sectors or domain. Thecore goal of ontologies is to provide a vision of a domain. Ontologies consist of all relevant domain-specific terminologies and connections that help to identify core concepts and accumulate critical information related to the domain. Nowadays, ontology is deployed in various fields to capture the domain knowledge. The use of ontology in various sectors is shown in Fig.1 and explained further.
