==== Definition Variants====

'''V1.1''' [ [[Edu:TermlistReferences#arpetal2015|Arp et al., 2015]] ]
* A [[Edu:RealizableEntity|realizable entity]] that (1) exists because the bearer is in some special physical, social, or institutional set of circumstances in which the bearer does not have to be, and (2) is not such that, if this realizable entity ceases to exist, then the physical make-up of the bearer is thereby changed. A role is thus always optional.

'''V1.2''' [ [[Edu:TermlistReferences#masoloetal2004|Masolo et al., 2004]] ]
* A role is a [[Edu:concept|concept]] that can be ‘played’ (in a contingent and temporary way) by certain [[Edu:entity|entities]], when they enter in [[Edu:relation|relationships]] with other entities. Social roles, more specifically, have four characteristics: 1) (i) Roles are (unary) ‘[[Edu:property|properties]]’, 2) Roles are [[Edu:anti-rigid|anti-rigid]] and they have ‘dynamic’ properties, 3) roles have a relational nature, and 4) roles are linked to contexts.

'''V1.3''' [ [[Edu:TermlistReferences#halpin2008|Halpin and Morgan, 2008]] ]
* Role is what an object plays in a relation (called 'fact type' in ORM terminology). Context: conceptual data modelling.

'''V1.4''' [ [[Edu:TermlistReferences#jurafsky08|Jurafsky and Martin, 2008]] ]
* Role refers to the argument of a verb, aimed at representing meaning. This can be a thematic role, such as 'agent' or a deep role, such as 'worker'. Thematic roles generalise over the deep roles. Context: linguistics.
