binary relation |
BinaryRelations are relations that are true only of pairs of things. BinaryRelations are represented as slots in frame systems.
|
| Children |
asymmetric relation | A BinaryRelation is asymmetric if and only if it is both an AntisymmetricRelation and an IrreflexiveRelation. |
| Instances | ancestor | The transitive closure of the parent predicate. (ancestor ?DESCENDANT ?ANCESTOR) means that ?ANCESTOR is either the parent of ?DESCENDANT or the parent of the parent of DESCENDANT or etc. |
| | ancestor organization | (ancestorOrganization ?ORG1 ?ORG2) means that the Organization ?ORG1 descended from the Organization ?ORG2. |
| | antagonist muscles | A relation between two Muscles that put opposing forces on a part of the body. |
| | attribute | (attribute ?OBJECT ?PROPERTY) means that ?PROPERTY is a Attribute of ?OBJECT. For example, (attribute MyLittleRedWagon Red). |
| | before | (before ?POINT1 ?POINT2) means that ?POINT1 precedes ?POINT2 on the universal timeline. |
| | brother | The general relationship of being a brother. (brother ?MAN ?PERSON) means that ?MAN is the brother of ?PERSON. |
| | classmate | (classmate ?A1 ?A2 ?COURSE) means that both ?A1 and ?A2 were a GroupOfPeople who were taught under the same EducationalCourse (?COURSE). |
| | colleague | (colleague ?A1 ?A2 ?ORG) means that ?A1 and ?A2 are colleagues when they both are hired (employs) by the same ?ORG. |
| | conjugate | (conjugate ?COMPOUND1 ?COMPOUND2) means that ?COMPOUND1 and ?COMPOUND2 are identical CompoundSubstances except that one has one more Proton than the other. |
| | connected engineering components | This is the most general connection relation between EngineeringComponents. If (connectedEngineeringComponents ?COMP1 ?COMP2), then neither ?COMP1 nor ?COMP2 can be an engineeringSubcomponent of the other. The relation connectedEngineeringComponents is a SymmetricRelation, there is no information in the direction of connection between two components. It is also an IrreflexiveRelation, no EngineeringComponent bears this relation to itself. Note that this relation does not associate a name or type with the connection. |
| | customer | A very general relation that exists whenever there is a FinancialTransaction between the two Agents such that the first is the destination of the FinancialTransaction and the second is the agent. |
| | decreases likelihood | One of the basic ProbabilityRelations. (decreasesLikelihood ?FORMULA1 ?FORMULA2) means that ?FORMULA2 is less likely to be true if ?FORMULA1 is true. |

| | disjoint relation | This predicate relates two Relations. (disjointRelation ?REL1 ?REL2) means that the two relations have no tuples in common. |
| | during | (during ?INTERVAL1 ?INTERVAL2) means that ?INTERVAL1 starts after and ends before ?INTERVAL2. |
| | earlier | (earlier ?INTERVAL1 ?INTERVAL2) means that the TimeInterval ?INTERVAL1 ends before the TimeInterval ?INTERVAL2 begins. |
| | export partner | (exportPartner ?AGENT1 ?AGENT2) means that the AutonomousAgent ?AGENT1 exports goods to the AutonomousAgent ?AGENT2. |
| | finishes | (finishes ?INTERVAL1 ?INTERVAL2) means that ?INTERVAL1 and ?INTERVAL2 are both TimeIntervals that have the same ending TimePoint and that ?INTERVAL2 begins before ?INTERVAL1. |
| | finishes during | (finishesDuring ?INTERVAL1 ?INTERVAL2) means that the end point of ?INTERVAL1 ends during ?INTERVAL2. |
| | graph part | A basic relation for Graphs and their parts. (graphPart ?PART ?GRAPH) means that ?PART is a GraphArc or GraphNode of the Graph ?GRAPH. |
| | greater than | (greaterThan ?NUMBER1 ?NUMBER2) is true just in case the Quantity ?NUMBER1 is greater than the Quantity ?NUMBER2. |
| | hinders subclass | A very general Predicate. (hindersSubclass ?PROC1 ?PROC2) means that the Process ?PROC1 hindersSubclass or hinders the occurrence of the Process ?PROC2. For example, obstructing an object hindersSubclass moving it. Note that this is a relation between types of Processes, not between instances. |
| | hostile forces | (hostileForces ?UNIT1 ?UNIT2) means that the MilitaryUnits ?UNIT1 and ?UNIT2 are, respectively, allied with GeopoliticalAreas that are at war with one another. |
| | husband | (husband ?MAN ?WOMAN) means that ?MAN is the husband of ?WOMAN. |
| | import partner | (importPartner ?AGENT1 ?AGENT2) means that the AutonomousAgent ?AGENT1 imports goods from the AutonomousAgent ?AGENT2. |
| | increases likelihood | One of the basic ProbabilityRelations. (increasesLikelihood ?FORMULA1 ?FORMULA2) means that ?FORMULA2 is more likely to be true if ?FORMULA1 is true. |
| | inverse | The inverse of a BinaryRelation is a Relation in which all the tuples of the original Relation are reversed. In other words, one BinaryRelation is the inverse of another if they are equivalent when their arguments are swapped. |
| | larger | (larger ?OBJ1 ?OBJ2) means that ?OBJ1 is larger, with respect to all LengthMeasures, than ?OBJ2. |
| | less than | (lessThan ?NUMBER1 ?NUMBER2) is true just in case the Quantity ?NUMBER1 is less than the Quantity ?NUMBER2. |
| | manner | (manner ?PROCESS ?MANNER) means that the Process ?PROCESS is qualified by the Attribute ?MANNER. The Attributes of Processes are usually denoted by adverbs and include things like the speed of the wind, the style of a dance, or the intensity of a sports competition. |
| | meets spatially | (meetsSpatially ?OBJ1 ?OBJ2) means that ?OBJ1 and ?OBJ2 are connected but that neither ?OBJ1 nor ?OBJ2 overlapsSpatially the other. |
| | modal attribute | A BinaryRelation that is used to state the normative force of a Proposition. (modalAttribute ?FORMULA ?PROP) means that the Proposition expressed by ?FORMULA has the NormativeAttribute ?PROP. For example, (modalAttribute (exists (?ACT ?OBJ) (and (instance ?ACT Giving) (agent ?ACT John) (patient ?ACT ?OBJ) (destination ?ACT Tom))) Obligation) means that John is obligated to give Tom something. |
| | neighbor | (neighbor ?PERSON1 ?PERSON2) means that ?PERSON1 is a neighbor of ?PERSON2, i.e. ?PERSON1 and ?PERSON2 have their homes Near one another. |
| | operator | (operator ?OBJECT ?AGENT) means that ?AGENT determines how ?OBJECT is used, either by directly or indirectly operating it. |
| | opposite direction | (oppositeDirection ?DIR1 ?DIR2) means that the PositionalAttribute ?DIR1 points in the compass direction opposite to the DirectionalAttribute ?DIR2. |
| | overlap partially | (overlapsPartially ?OBJ1 ?OBJ2) means that ?OBJ1 and ?OBJ2 have part(s) in common, but neither ?OBJ1 nor ?OBJ2 is a part of the other. |
| | prevents subclass | A very general Predicate. (preventsSubclass ?PROC1 ?PROC2) means that ?PROC1 preventsSubclass the occurrence of ?PROC2. In other words, if ?PROC1 is occurring in a particular time and place, ?PROC2 cannot occur at the same time and place. For example, innoculating preventsSubclass contracting disease. Note that this is a relation between types of Processes, not between instances. |
| | sibling | The relationship between two Organisms that have the same mother and father. Note that this relationship does not hold between half-brothers, half-sisters, etc. |
| | sister | The general relationship of being a sister. (sister ?WOMAN ?PERSON) means that ?WOMAN is the sister of ?PERSON. |
| | smaller | (smaller ?OBJ1 ?OBJ2) means that ?OBJ1 is smaller, with respect to all LengthMeasures, than ?OBJ2. |
| | spouse | The relationship of marriage between two Humans. |
| | starts | (starts ?INTERVAL1 ?INTERVAL2) means that ?INTERVAL1 and ?INTERVAL2 are both TimeIntervals that have the same initial TimePoint and that ?INTERVAL1 ends before ?INTERVAL2. |
| | starts during | (startsDuring ?INTERVAL1 ?INTERVAL2) means that the end point of ?INTERVAL1 starts during ?INTERVAL2. |
| | sub field | (subField ?FIELD1 ?FIELD2) means that ?FIELD1 is a proper part of the ?FIELD2. For example, Physiology is a subField of Biology. |
| | sub plan | (subPlan ?PLAN1 ?PLAN2) means that ?PLAN1 is a Plan which is a proper part of ?PLAN2. This relation is generally used to relate a supporting Plan to the overall Plan in a particular context. |
| | sub proposition | (subProposition ?PROP1 ?PROP2) means that ?PROP1 is a Proposition which is a proper part of the Proposition ?PROP2. In other words, subProposition is the analogue of properPart for chunks of abstract content. |
| | successor attribute closure | The transitive closure of successorAttribute. (successorAttributeClosure ?ATTR1 ?ATTR2) means that there is a chain of successorAttribute assertions connecting ?ATTR1 and ?ATTR2. |
| | superficial part | (superficialPart ?OBJ1 ?OBJ2) means that ?OBJ1 is a part of ?OBJ2 that has no interior parts of its own (or, intuitively, that only overlaps those parts of ?OBJ2 that are externally connected with the mereological complement of ?OBJ2). This too is a transitive relation closed under MereologicalSumFn and MereologicalProductFn. |
| | wife | (wife ?WOMAN ?MAN) means that ?WOMAN is the wife of ?MAN. |
