Graphical representation



General description

Name: Affordance
Submitted by: AndreaNuzzolese
Also Known As:
Intent: To represent the model for supporting the action selection mechanism.
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.
