What is the frame problem in knowledge representation?

  • A.Deciding which frame to use for a given object
  • B.Representing the boundary of the domain of interest
  • C.Choosing which slots a frame should contain
  • D.Stating concisely what an action leaves unchanged

Answer: D

Describing an action requires saying not only what it changes but that everything else stays the same, and enumerating those frame axioms for every action and every fluent is impossible. Successor state axioms and non-monotonic solutions address it. Frame selection, domain boundaries and slot design are different problems sharing the word. A difficulty that seems trivial to a person and proves intractable to formalise is characteristic of commonsense reasoning.
