波高
waveHeight
是一个二元谓语
BinaryPredicate
. (waveHeight ?WW ?X) 的意思是 ?X 高度 (
LengthMeasure
)是水体(
BodyOfWater
)兴起 ?WW (
WaterWave
波浪)的 波峰和前面波谷高度(
altitude
)的差别。

A
ConstantQuantity
is a
PhysicalQuantity
that has a constant value, e.g. 3
Meter
s and 5
HourDuration
s. The magnitude (see
MagnitudeFn
) of every
ConstantQuantity
is a
RealNumber
.
ConstantQuantity
is distinguished from
FunctionQuantity
, in that each instance of the latter is formed through the mapping of one
PhysicalQuantity
to another
PhysicalQuantity
. Each instance of
ConstantQuantity
is expressed with the
BinaryFunction
MeasureFn
, which takes a
Number
and a
UnitOfMeasure
as arguments. For example, 3
Meter
s is expressed as (
MeasureFn
3
Meter
). Instances of
ConstantQuantity
form a partial order (see
PartialOrderingRelation
) with the
lessThan
relation, since
lessThan
is a
RelationExtendedToQuantities
and
lessThan
is defined over the
RealNumber
s. The
lessThan
relation is not a total order (see
TotalOrderingRelation
) over the class
ConstantQuantity
since elements of some subclasses of
ConstantQuantity
(such as length quantities) are incomparable to elements of other subclasses of
ConstantQuantity
(such as mass quantities).
Instances
抽象体
这些特质或质量,和任何以物理媒介化身的特质/质量不同。抽象 的实例在意义上,可以说是像数学物体如集合和关系般存在,但是它们不能没有任何物理编码或化身便存在于特定的时间 和地点。
二元谓语
这是一个联系两个项目的
Predicate
- 它的配价是二。
二元关系
BinaryRelation
是只有在关系联系两样东西的时候 才算是真,框架理论以槽代表
BinaryRelation
。
实体
The universal class of individuals. This is the root node of the ontology.
可继承的关系
这是一个
Relation
类别,它的特性可以是 通过
subrelation
Predicate
把特性在类别的层次结构承传下去。
谓语
Predicate
是一个作句的
Relation
,这个
Relation
的每一个元组都是物体有限、有序的的句子。一个特定组员是一个
Predicate
的元素这事实,由 '(*predicate* arg_1 arg_2 .. arg_n)'来表示, arg_i 是关联的事物。在
BinaryPredicate
的情况下, 可以读成 `arg_1 是 *predicate* arg_2' 或者 `arg_1 的一个 *predicate* 是 arg_2'。
关系
这是关系的
Class
。现有三类的
Relation
:
Predicate
,
Function
和
List
。
Predicate
和
Function
皆表示有序的n元组集合, 这两个
Class
的差别在于
Predicate
包括组成公式的运算符,而
Function
则包括组成 术语的运算符,而一个
List
却是一个特定的有序n元组。
