KR

   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.
