<artificial intelligence, information science> 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 facts and rules 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.
