Which benefit follows from making control knowledge explicit?

  • A.The system can explain its strategy as well as its conclusions
  • B.The inference engine runs faster because it no longer needs to search the conflict set at all
  • C.Fewer rules are needed
  • D.The knowledge base can be verified automatically without any human being having to read it

Answer: A

When strategy is stated as knowledge rather than buried in the engine, it can be examined, explained, taught and changed like any other knowledge. NEOMYCIN exploited exactly this to tutor diagnostic method rather than merely diagnostic conclusions. Speed, rule count and automatic verification are not consequences. The pattern recurs whenever a system is asked to justify how it went about a problem. Working one numerical case through both cases side by side fixes the distinction better than any rule of thumb.
