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。
Relationships      
Parents 关系 The Class of relations. There are three kinds of Relation: Predicate, Function, and List. 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. A List, on the other hand, is a particular ordered n-tuple.
Children 二元函数The Class of Functions that require two arguments.
 二元谓语A Predicate relating two items - its valence is two.
 二元关系BinaryRelations are relations that are true only of pairs of things. BinaryRelations are represented as slots in frame systems.
 格角色The Class of Predicates relating the spatially distinguished parts of a Process. CaseRoles include, for example, the agent, patient or destination of an action, the flammable substance in a burning process, or the water that falls in rain.
 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 SetOrClass, and each element of the range is an instance of the SetOrClass.
 有意图的关系The Class of Relations between an Agent and one or more Entities, where the Relation requires that the Agent have awareness of the Entity.
 对象态度The Class of IntentionalRelations where the Agent has awareness of an instance of Physical.
 谓语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 BinaryPredicates, the fact can be read as `arg_1 is *predicate* arg_2' or `a *predicate* of arg_1 is arg_2'.
 概率关系The Class of Relations that permit assessment of the probability of an event or situation.
 命题态度The Class of IntentionalRelations where the Agent has awareness of a Proposition.
 四元函数The Class of Functions that require exactly four arguments.
 四元谓语The Class of Predicates that require four arguments.
 四元关系QuaternaryRelations relate four items. The two subclasses of QuaternaryRelation are QuaternaryPredicate and TernaryFunction.
 五元谓语The Class of Predicates that require five arguments.
 五元关系QuintaryRelations relate five items. The two subclasses of QuintaryRelation are QuintaryPredicate and QuaternaryFunction.
 延伸数量关系A RelationExtendedToQuantities is a Relation that, when it is true on a sequence of arguments that are RealNumbers, it is also true on a sequence of instances of ConstantQuantity with those magnitudes in some unit of measure. For example, the lessThan relation is extended to quantities. This means that for all pairs of quantities ?QUANTITY1 and ?QUANTITY2, (lessThan ?QUANTITY1 ?QUANTITY2) if and only if, for some ?NUMBER1, ?NUMBER2, and ?UNIT, ?QUANTITY1 = (MeasureFn ?NUMBER1 ?UNIT), ?QUANTITY2 = (MeasureFn ?NUMBER2 ?UNIT), and (lessThan ?NUMBER1 ?NUMBER2), for all units ?UNIT on which ?QUANTITY1 and ?QUANTITY2 can be measured. Note that, when a RelationExtendedToQuantities is extended from RealNumbers to instances of ConstantQuantity, the ConstantQuantity must be measured along the same physical dimension.
 单值关系A Relation is a SingleValuedRelation just in case an assignment of values to every argument position except the last one determines at most one assignment for the last argument position. Note that not all SingleValuedRelations are TotalValuedRelations.
 空间关系The Class of Relations that are spatial in a wide sense. This Class includes mereological relations and topological relations.
 时间关系The Class of temporal Relations. This Class includes notions of (temporal) topology of intervals, (temporal) schemata, and (temporal) extension.
 三元函数The Class of Functions that require exactly three arguments.
 三元谓语The Class of Predicates that require exactly three arguments.
 三元关系TernaryRelations relate three items. The two subclasses of TernaryRelation are TernaryPredicate and BinaryFunction.
 总值关系A Relation is a TotalValuedRelation just in case there exists an assignment for the last argument position of the Relation given any assignment of values to every argument position except the last one. Note that declaring a Relation to be both a TotalValuedRelation and a SingleValuedRelation means that it is a total function.
 一元函数The Class of Functions that require a single argument.
