General description


Name:	Affordance
Submitted by:	AndreaNuzzolese
Also Known As:
Intent:	To represent the model for supporting the action selection mechanism.
Domains:
Competency Questions:	Which is the strength of an Affordance? Which tasks are afforded in a certain situation?How should an agent behave in a certain situation?Which are the parameters involved in certain task?
Solution description:	The Afforndance ODP relies on the descriptions and situations ODP, and is combined with a frame-based representation scheme. This allows to extend the notion of affordance not only to physical objects, but also complex situations afford actions.
