Sigma KEE - SingleValuedRelation
KB Term: 
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
单值关系
一个 RelationSingleValuedRelation 以确保除了最后一个参数之外,每一个参数的位置只有一个赋值,而最后的参数 顶多可以决定最后一个参数的位置。注:不是所有的 SingleValuedRelation 都是 TotalValuedRelation
Relationships      
Parents 可继承的关系 The class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.
  关系 The Class of relations. There are two kinds of Relation: Predicate and Function. Predicates and Functions both denote sets of ordered n-tuples. The difference between these two Classes is that Predicates cover formula-forming operators, while Functions cover term-forming operators.
Children 函数A Function is a term-forming Relation that maps from a n-tuple of arguments to a range and that associates this n-tuple with at most one range element. Note that the range is a Class, and each element of the range is an instance of the Class.
Instances年龄这只是把一个 Object 和一个用来指定这个 Object 的岁数的 ConstantQuantity 联系起来。
 海拔这是一个 TernaryPredicate,它是用来表示一个 Objecttop 和这个 Object top 以下的另外一点 (通常这一点会是海平面)之间的 distance。注:这个 Predicate 可以用来指定例如地理特征的高度如山、飞机的高度和环绕地球的卫星轨道。
 近似直径这是假设一个为和它体积相同的完美球体的直径。
 弧衡量这个谓词表示 GraphArc 在一个 Graph 的值。 这可以 表示一个道路网络的长度,或者是管道系统内管道的流量。
 平均这是一个部分函数,只要一个 List 的元素都是 RealNumber,它会把这个List 和一个 RealNumber 联系起来。和这个 List 联系的 RealNumber 等于这个 List 内的 RealNumber 的数学平均 除以列表元素的总数。
 结论(conclusion ?ARGUMENT ?PROPOSITION)的意思是 Proposition ?PROPOSITION 是由 Argument ?ARGUMENT 所得出明确的结论。注:有可能是但也有可能不是 由 ?ARGUMENT entails ?PROPOSITION。
 货币类型(currencyType ?AREA ?UNIT) means that the official currency used in the GeopoliticalArea ?AREA is the UnitOfMeasure ?UNIT.
 日期这是一个 BinaryPredicate, 它以绝对日历时间,以一天为限, 为特定的 ObjectProcess 指定一个 TimePosition
 深度这是一个 TernaryPredicate,它是用来表示一个 Objecttop 和这个 Object top 以上的另外一点 (通常这一点会是海平面)之间的 distance。注这个 Predicate 可以用来指定例如海洋生物或潜艇的深度。
 圆周(diameter ?CIRCLE ?LENGTH) 的意思是 Circle ?CIRCLE 的直径的长度是 ?LENGTH。
 距离(distance ?OBJ1 ?OBJ2 ?QUANT) 的意思是两个物体 ?OBJ1 和 ?OBJ2 最短的距离是 ?QUANT。注:谓词 lengthdistance 之间的分别在于,length 是用来表示一个单一物体其中一个维度的 LengthMeasure,而是用来表示两个不同物体之间的LengthMeasure
 有效范围Models the effective range of some device that is able to move by itself (like vehicles, rockets and so on) or move other things (like weapons).
 电子数(electronNumber ?SUBSTANCE ?NUMBER) means that the PureSubstance ?SUBSTANCE has the number of Electrons ?NUMBER.
 父亲这是父亲的概括关系。(father ?CHILD ?FATHER)的意思是 ?FATHER 是 ?CHILD 的亲生父亲。
 病毒的遗传基质(geneticSubstrateOfVirus ?VIRUS ?MOL) relates the virus ?VIRUS to the molecule ?MOL that contains its genetic information.
 几何距离(geometricDistance ?POINT1 ?POINT2 ?LENGTH) 的意思是 ?LENGTH 是两个 GeometricPoint ?POINT1 和 ?POINT2 之间的距离。
 有维度multipole quantity has certain dimension
 有变数multipole quantity has certain variable
 人的能力(humanCapacity ?CONSTRUCT ?NUMBER) means that the StationaryArtifact ?CONSTRUCT, e.g. a Building or a Room, can hold a maximum of ?NUMBER Humans without crowding.
 智商(intelligenceQuotient ?PERSON ?NUMBER) means that ?NUMBER is the I.Q. of ?PERSON. The I.Q. of a person is the ratio of their mental age (determined by a standardized test) divided by their chronological age, multiplied by 100.
 入侵病毒(invadingVirus ?CELLINV ?VIRUS) means that ?VIRUS is a virus that invades a host cell in the cell invasion ?CELLINV. If the invasion results in a replication, it is the genome of the invading virus that is replicated. The original virus is destroyed but replicated in the process.
 leader(leader ?INSTITUTION ?PERSON) means that the leader of ?INSTITUTION is ?PERSON.
 长度这是一个 BinaryPredicate,它是用来表示一个 Object最 长部分的幅度。
 货币价值这是一个 BinaryPredicate,它把一个 ObjectProcess 和以一个CurrencyMeasure来表示它的价值联系起来。
 母亲这是母亲的概括关系。(mother ?CHILD ?MOTHER)的意思是 ?MOTHER 是 ?CHILD 的亲生母亲。
 净值Total assets minus total liabilities of an individual or company.
 质子数(protonNumber ?SUBSTANCE ?NUMBER) means that the PureSubstance ?SUBSTANCE has the number of Protons ?NUMBER.
 半径(radius ?CIRCLE ?LENGTH) 的意思是 Circle ?CIRCLE 的半径的长度是 ?LENGTH。
 StringConcatenateFnThe result of applying this Function to two SymbolicString arguments is a third SymbolicString that is the concatenation of the two arguments. Example: (equal "Charles Darwin" (StringConcatenateFn "Charles " "Darwin")).
 stringConcatenation(stringConcatenation ?SymbolicString-1 ?SymbolicString-2 ?SymbolicString-3) means that ?SymbolicString-3 can be formed by appending ?SymbolicString-1 and ?SymbolicString-2, in order. Example: (stringConcatenation "Charles " "Darwin" "Charles Darwin") is a True Sentence.
 stringLength(stringLength ?NonnegativeInteger ?SymbolicString) means that the number of Characters in ?SymbolicString is ?NonnegativeInteger. Example: (stringLength 14 "Charles Darwin"), which is a True Sentence.
 StringLengthFnThis UnaryFunction takes a SymbolicString as its sole argument. The result of evaluating a term formed with StringLengthFn is a NonnegativeInteger that denotes the number of Characters in the SymbolicString. Example: (equal 14 (StringLengthFn "Charles Darwin")).
 SubstringFn(SubstringFn ?SymbolicString ?NonnegativeInteger-1 ?NonnegativeInteger-2) denotes a string that is a subString of ?SymbolicString, begins with the Character at the index ?NonnegativeInteger-1, and ends with the Character at the index (SubtractionFn ?NonnegativeInteger-2 1). The first Character in ?SymbolicString is denoted by the index 0. If the value of ?NonnegativeInteger-1 or ?NonnegativeInteger-2 is greater than the value of (StringLengthFn ?SymbolicString), or if ?NonnegativeInteger-1 is greater than ?NonnegativeInteger-2, the result of evaluating the SubstringFn expression is undefined. Example: (equal "Charle" (SubstringFn "Charles Darwin" 0 6)).
 交易金额(transactionAmount ?TRANSACTION ?AMOUNT)的意思是: ?AMOUNT 是在 FinancialTransaction ?TRANSACTION 中所交换 CurrencyMeasure 的实例。
 唯一识别符号这是专门识别 Entity 的一个实例的 names 类别,uniqueIdentifier 的一些例子包括数据库应用程序数据库表的索引,和ISBN(国际标准书号)。
 配价指定一个关系可接纳参数的数目。 如果一个关系没有设定参数 数目,那么它就没有配价,它也就是 VariableArityRelation 的一个实例。
 波长(wavelength ?RADIATION ?MEASURE) means that the instance of radiation, ?RADIATION, has an average wavelength of ?MEASURE.
 宽度这是一个 BinaryPredicate, 它是用来表示一个 Object 从 一边到另一边最大的距离。
