Semantic reasoner
A
semantic reasoner
,
reasoning engine
,
rules engine
, or simply a
reasoner
, is a piece of software able to infer
logical consequences
from a set of asserted facts or
axioms
. The notion of a semantic reasoner generalizes that of an
inference engine
, by providing a richer set of mechanisms to work with. The
inference rules
are commonly specified by means of an
ontology language
, and often a
description language
. Many reasoners use
first-order predicate logic
to perform reasoning;
inference
commonly proceeds by
forward chaining
and
backward chaining
. There are also examples of probabilistic reasoners, including Pei Wang's non-axiomatic reasoning system, and
probabilistic logic networks
.
