Sigma KEE - resource
(resource ?PROCESS ?RESOURCE) means that ?RESOURCE is present at the beginning of ?PROCESS, is used by ?PROCESS, and as a consequence is changed by ?PROCESS. For example, soap is a resource in the following proposition: the gun was carved out of soap. Note that resource differs from instrument, another subrelation of patient, in that its internal or physical properties are altered in some way by the Process.
Parents patient (patient ?PROCESS ?ENTITY) means that ?ENTITY is a participant in ?PROCESS that may be moved, said, experienced, etc. For example, the direct objects in the sentences 'The cat swallowed the canary' and 'Billy likes the beer' would be examples of patients. Note that the patient of a Process may or may not undergo structural change as a result of the Process. The CaseRole of patient is used when one wants to specify as broadly as possible the object of a Process.
Children reactant(reactant ?PROCESS ?SUBSTANCE) means that ?SUBSTANCE is a chemical reactant in the chemical reaction ?PROCESS, i.e. ?SUBSTANCE is present at the beginning of the chemical reaction ?PROCESS.
InstancesabstractProperties 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.
 antisymmetric relationBinaryRelation ?REL is an AntisymmetricRelation if for distinct ?INST1 and ?INST2, (?REL ?INST1 ?INST2) implies not (?REL ?INST2 ?INST1). In other words, for all ?INST1 and ?INST2, (?REL ?INST1 ?INST2) and (?REL ?INST2 ?INST1) imply that ?INST1 and ?INST2 are identical. Note that it is possible for an AntisymmetricRelation to be a ReflexiveRelation.
 asymmetric relationA BinaryRelation is asymmetric if and only if it is both an AntisymmetricRelation and an IrreflexiveRelation.
 binary predicateA Predicate relating two items - its valence is two.
 binary relationBinaryRelations are relations that are true only of pairs of things. BinaryRelations are represented as slots in frame systems.
 case roleThe 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.
 entityThe universal class of individuals. This is the root node of the ontology.
 inheritable relationThe class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.
 irreflexive relationRelation ?REL is irreflexive iff (?REL ?INST ?INST) holds for no value of ?INST.
 partial valued relationA Relation is a PartialValuedRelation just in case it is not a TotalValuedRelation, i.e. just in case assigning values to every argument position except the last one does not necessarily mean that there is a value assignment for the last argument position. Note that, if a Relation is both a PartialValuedRelation and a SingleValuedRelation, then it is a partial function.
 predicateA 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'.
 relationThe 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.
