knowledge representation

Computing Dictionary

knowledge representation definition

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.

"People accept a representation in which the elements of wish and fantasy are purposely included but which nevertheless proclaims to represent "the past" and to serve as a guide-rule for life, thereby hopelessly confusing the spheres of knowledge and will."

-Johan Huizinga
