The AI sub-field of ontology deals with creating and using formal knowledge structures that can help us draw conclusions efficiently. For example, one can easily say via an ontology that any person in a particular physical location cannot be simultaneously at another physical location. In contrast, no amount of data about a person and their locations can help us draw the same conclusion! An ontology can be built using abstract concepts, like a person and a city, but becomes a knowledge graph (KG) when it covers physical instances, like William Shakespeare and London.
