WHAT's GLOBAL ONTOLOGY

GLOBAL ONTOLOGY

Ontology is the philosphical study of what exists. In the Artificial Intelligence context, ontology is concerned with which categories we can usefully quantify over and how those categories relate to each other. All knowledge-based systems refer to entities in the world,but in order to capture the breadth of human knowledge, we need a well designed global ontology that specifies at a very high level what kinds of thing exist and what their general properties are. as mentioned abov, such a global ontology should provide a mopre solid foundationfor domain specific AI programs and should also allow them to communicate with each other.
The highest level concept in CYC is called thing. Everything is an instance of thing. Below this top-level concept, CYC makes several distinctions, including:
* Individual object Versus Collection.
* Intangible, Tangible, and Composite.
* Substance.
* Intrinsic VersusExtrinsic properties.
* Event and Process.
* Slots.
* Time.
* Agent.
