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. |
| BinaryPredicate | A Predicate relating two items - its valence is two. |
| BinaryRelation | BinaryRelations are relations that are true only of pairs of things. BinaryRelations 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 Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate. |
| 有意圖的關係 | The Class of Relations between an AutonomousAgent and one or more Entities, where the Relation requires that the AutonomousAgent have awareness of the Entity. |
| 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 BinaryPredicates, 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. 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. |
| SymmetricRelation | A BinaryRelation ?REL is symmetric just iff (?REL ?INST1 ?INST2) imples (?REL ?INST2 ?INST1), for all ?INST1 and ?INST2. |
