Description-en: semantic web reasoning engine
Euler Yet another proof Engine (EYE) is a reasoning engine
supporting the Semantic Web layers.
It performs semibackward chaining and it supports Euler paths.
Via N3 it is interoperable with Cwm.
.
Semibackward chaining
is backward chaining for rules using <= in N3
and forward chaining for rules using => in N3.
This can be seen in EYE Reasoning.
.
Euler paths are roughly "don't step in your own steps"
which is inspired by what Leonhard Euler discovered in 1736
for the Königsberg Bridge Problem.
EYE sees the rule P => C as P & NOT(C) => C.
.
Notation3 (N3) is a shorthand non-XML serialization
of Resource Description Framework (RDF) models,
designed with human-readability in mind:
N3 is much more compact and readable than XML RDF notation.
.
Resource Description Framework (RDF) is a standard model
for data interchange on the Web.
