Knowledge or information based on real occurrences: an account based on fact; a blur of fact and fancy.
1. Something demonstrated to exist or known to have existed: Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact.
2. A real occurrence; an event: had to prove the facts of the case.
3. Something believed to be true or real: a document laced with mistaken facts.

Law The aspect of a case at law comprising events determined by evidence: The jury made a finding of fact.

[Latin factum, deed, from neuter past participle of facere, to do; see dhē- in Indo-European roots.]

Usage Note: Fact has a long history of usage in the sense "allegation of fact," as in "This tract was distributed to thousands of American teachers, but the facts and the reasoning are wrong" (Albert Shanker). This practice has led to the introduction of the phrases true facts and real facts, as in The true facts of the case may never be known. These usages may occasion qualms among critics who insist that facts can only be true, but the usages are often useful for emphasis.

fact

1539, "action," especially "evil deed," from L. factum "event, occurrence," lit. "thing done," from neut. pp. of facere "to do" (see factitious). Usual modern sense of "thing known to be true" appeared 1632, from notion of "something that has actually occurred." Facts of life "harsh realities" is from 1854; specific sense of "human sexual functions" first recorded 1913. Factoid is from 1973, first explained, if not coined, by Norman Mailer.

"Factoids ... that is, facts which have no existence before appearing in a magazine or newspaper, creations which are not so much lies as a product to manipulate emotion in the Silent Majority." [N. Mailer, "Marilyn," 1973]

FACT
Fully Automated Compiling Technique

fact artificial intelligence, programming
The kind of clause used in logic programming which has no subgoals and so is always true (always succeeds). E.g.
wet(water). male(denis).
This is in contrast to a rule which only succeeds if all its subgoals do. Rules usually contain logic variables, facts rarely do, except for oddities like "equal(X,X).".
