The ability to manipulate the existing knowledge representational structures to derive new structures, is known as :

  • A.Representational adequacy
  • B.Inferential adequacy
  • C.Inferential efficiency
  • D.Acquisitional efficiency

Answer: B

The ability is Inferential adequacy.

Rich and Knight list four properties of a good knowledge representation system. Inferential adequacy is the ability to manipulate the representational structures to derive new structures corresponding to new knowledge inferred from old.

Representational adequacy is the ability to represent all the kinds of knowledge needed, inferential efficiency is the ability to direct inference along the most promising paths, and acquisitional efficiency is the ability to acquire new information easily.
