Relationships
Instances
Abstract
Properties or qualities as distinguished from any particular embodiment of the properties/qualities in a physical medium. Instances of Abstract can be said to exist in the same sense as mathematical objects such as sets and relations, but they cannot exist at a particular place and time without some physical encoding or embodiment.
AntisymmetricRelation
BinaryRelation
?REL is an
AntisymmetricRelation
if for distinct ?INST1 and ?INST2, (?REL ?INST1 ?INST2) implies not (?REL ?INST2 ?INST1). In other words, for all ?INST1 and ?INST2, (?REL ?INST1 ?INST2) and (?REL ?INST2 ?INST1) imply that ?INST1 and ?INST2 are identical. Note that it is possible for an
AntisymmetricRelation
to be a
ReflexiveRelation
.
AsymmetricRelation
A
BinaryRelation
is asymmetric if and only if it is both an
AntisymmetricRelation
and an
IrreflexiveRelation
.
BinaryPredicate
A
Predicate
relating two items - its valence is two.
BinaryRelation
BinaryRelation
s are relations that are true only of pairs of things.
BinaryRelation
s are represented as slots in frame systems.
Entity
The universal class of individuals. This is the root node of the ontology.
可繼承的關係
The class of
Relation
s whose properties can be inherited downward in the class hierarchy via the
subrelation
Predicate
.
IrreflexiveRelation
Relation
?REL is irreflexive iff (?REL ?INST ?INST) holds for no value of ?INST.
Predicate
A
Predicate
is a sentence-forming
Relation
. Each tuple in the
Relation
is a finite, ordered sequence of objects. The fact that a particular tuple is an element of a
Predicate
is denoted by '(*predicate* arg_1 arg_2 .. arg_n)', where the arg_i are the objects so related. In the case of
BinaryPredicate
s, the fact can be read as `arg_1 is *predicate* arg_2' or `a *predicate* of arg_1 is arg_2'.
Relation
The
Class
of relations. There are two kinds of
Relation
:
Predicate
and
Function
.
Predicate
s and
Function
s both denote sets of ordered n-tuples. The difference between these two
Class
es is that
Predicate
s cover formula-forming operators, while
Function
s cover term-forming operators.
