knowledge
<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.
