knowledge
The objects,
concepts and relationships that are assumed to exist in some
area of interest. A collection of {knowledge}, represented
using some {knowledge representation} language is known as a
{knowledge base} and a program for extending and/or querying a
knowledge base is a {knowledge-based system}.
Knowledge differs from {data} or {information} in that new
knowledge may be created from existing knowledge using logical
{inference}. If information is data plus meaning then
knowledge is information plus processing.
A common form of knowledge, e.g. in a {Prolog} program, is a
collection of {fact}s and {rule}s about some subject.
For example, a {knowledge base} about a family might contain
the facts that John is David's son and Tom is John's son and
the rule that the son of someone's son is their grandson.
From this knowledge it could infer the new fact that Tom is
David's grandson.
