Sigma KEE - Predicate
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
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'。
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 二元谓语A Predicate relating two items - its valence is two.
 ClosedWorldPredicate
 逻辑运算符This Class comprises all of the logical operators (viz. 'and', 'or', 'not', '=>', and '<=>').
 四元谓语The Class of Predicates that require four arguments.
 五元谓语The Class of Predicates that require five arguments.
 三元谓语The Class of Predicates that require exactly three arguments.
Instances相反属性contraryAttribute 是一组 Attribute ,而某一件事物不能同时拥有超过一种这个组里的 Attributes。 举例说: (contraryAttribute Pliable Rigid) 指的是没有一件东西是既 PliableRigid 的。
 不相交的分拆C ClassdisjointDecomposition 是C的一组相互 disjoint 的子类别。
 详尽的属性这个术语把一个 Class 联系到一组 Attribute, 就是说这个组的单元已经是这个 Class 所有的实例。举例说: (exhaustiveAttribute PhysicalState Solid Fluid Liquid Gas Plasma) 的意思是 PhysicalState 这个类别就 只有 SolidFluidLiquidGasPlasma 这五个实例了。
 彻底的分拆C ClassexhaustiveDecomposition 是C的一组子类别, 而C的每一个实例就是这个组内其中一个子类别的一个实例。按: 这并不一定是意会着这个组的单元都不相交 (可参考 partition - 一个 partition 是一个已列举尽 不相交的掏空成分。
 划分C Classpartition 是一组包括C,而互不 disjoint 的类别 (一个子类别的分区)。C的每一个实例正正是这个分区子类别的一个实例。
 进程列表The arguments of this relation are data structures, each of which contains the information necessary for the process already loaded by the operating system to execute on a processor.
