knowledge representation

The subfield of artificial intelligence concerned with

designing and using systems for storing knowledge - facts

and rules about some subject.

A body of formally represented knowledge is based on a

conceptualisation - an abstract view of the world that we

wish to represent. In order to manipulate this knowledge we

must specify how the abstract conceptualisation is represented

as a concrete data structure. An ontology is an explicit

specification of a conceptualisation.
