knowledge representation

   Also found in: Acronyms, Wikipedia 0.04 sec.

A method used to code knowledge in an expert system, typically a series of IF-THEN rules (IF this condition occurs, THEN take this action).

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.
