Ontology \On*tol"o*gy\, n. [Gr. ? the things which exist
(pl.neut. of ?, ?, being, p. pr. of ? to be) + -logy: cf. F.
ontologie.]
1. That department of the science of metaphysics which
investigates and explains the nature and essential
properties and relations of all beings, as such, or the
principles and causes of being.
[1913 Webster]

2. (Computers) A systematic arrangement of all of the
important categories of objects or concepts which exist in
some field of discourse, showing the relations between
them. When complete, an ontology is a categorization of
all of the concepts in some field of knowledge, including
the objects and all of the properties, relations, and
functions needed to define the objects and specify their
actions. A simplified ontology may contain only a
hierarchical classification (a taxonomy) showing the
type subsumption relations between concepts in the field
of discourse. An ontology may be visualized as an abstract
graph with nodes and labeled arcs representing the objects
and relations.

Note: The concepts included in an ontology and the
hierarchical ordering will be to a certain extent
arbitrary, depending upon the purpose for which the
ontology is created. This arises from the fact that
objects are of varying importance for different
purposes, and different properties of objects may be
chosen as the criteria by which objects are classified.
In addition, different degrees of aggregation of
concepts may be used, and distinctions of importance
for one purpose may be of no concern for a different
purpose.

ontology

1. A systematic account of Existence.

2. (From philosophy) An explicit
formal specification of how to represent the objects, concepts
and other entities that are assumed to exist in some area of
interest and the relationships that hold among them.

For AI systems, what "exists" is that which can be
represented. When the knowledge about a domain is
represented in a declarative language, the set of objects
that can be represented is called the universe of discourse.
We can describe the ontology of a program by defining a set of
representational terms. Definitions associate the names of
entities in the universe of discourse (e.g. classes,
relations, functions or other objects) with human-readable
text describing what the names mean, and formal axioms that
constrain the interpretation and well-formed use of these
terms. Formally, an ontology is the statement of a {logical
theory}.

A set of agents that share the same ontology will be able to
communicate about a domain of discourse without necessarily
operating on a globally shared theory. We say that an agent
commits to an ontology if its observable actions are
consistent with the definitions in the ontology. The idea of
ontological commitment is based on the Knowledge-Level
perspective.

3. The hierarchical structuring of
knowledge about things by subcategorising them according to
their essential (or at least relevant and/or cognitive)
qualities. See subject index. This is an extension of the
previous senses of "ontology" (above) which has become common
in discussions about the difficulty of maintaining {subject
indices}.

Natural Harmony (Mus.), the harmony of the triad or common
chord.

Natural history, in its broadest sense, a history or
description of nature as a whole, including the sciences
of botany, Zoology, geology, mineralogy,
paleontology, chemistry, and physics. In recent
usage the term is often restricted to the sciences of
botany and Zoology collectively, and sometimes to the
science of zoology alone.

Natural law, that instinctive sense of justice and of right
and wrong, which is native in mankind, as distinguished
from specifically revealed divine law, and formulated
human law.

Natural modulation (Mus.), transition from one key to its
relative keys.

Natural order. (Nat. Hist.) See under order.

Natural person. (Law) See under person, n.

Natural philosophy, originally, the study of nature in
general; the natural sciences; in modern usage, that
branch of physical science, commonly called physics,
which treats of the phenomena and laws of matter and
considers those effects only which are unaccompanied by
any change of a chemical nature; -- contrasted with
mental philosophy and moral philosophy.

Natural scale (Mus.), a scale which is written without
flats or sharps.

Note: Model would be a preferable term, as less likely to
mislead, the so-called artificial scales (scales
represented by the use of flats and sharps) being
equally natural with the so-called natural scale.

Natural science, the study of objects and phenomena
existing in nature, especially biology, chemistry, physics
and their interdisciplinary related sciences; {natural
history}, in its broadest sense; -- used especially in
contradistinction to social science, mathematics,
philosophy, mental science or moral science.

Natural selection (Biol.), the operation of natural laws
analogous, in their operation and results, to designed
selection in breeding plants and animals, and resulting in
the survival of the fittest; the elimination over time of
species unable to compete in specific environments with
other species more adapted to survival; -- the essential
mechanism of evolution. The principle of natural selection
is neutral with respect to the mechanism by which
inheritable changes occur in organisms (most commonly
thought to be due to mutation of genes and reorganization
of genomes), but proposes that those forms which have
become so modified as to be better adapted to the existing
environment have tended to survive and leave similarly
adapted descendants, while those less perfectly adapted
have tended to die out through lack of fitness for the
environment, thus resulting in the survival of the
fittest. See Darwinism.

Natural system (Bot. & Zool.), a classification based upon
real affinities, as shown in the structure of all parts of

divisions. --Gray.

existence and attributes of the Supreme Being which are
exhibited in nature; -- distinguished from {revealed
