Ontology engineering is the process of creating and maintaining a model or map of a particular area of knowledge. It is a way of organizing information and concepts so that they can be easily used and understood by a computer. Ontologies are usually created using specialized software tools, and they help make sense of the structure, rules, and relationships of a particular field of knowledge. The ontology is made up of terms, definitions, and relationships between these terms. Having a clear ontology helps people communicate more effectively and make better decisions.
