Which architecture lets several knowledge sources contribute opportunistically?

  • A.A blackboard system
  • B.A backward chaining system, which pursues one goal at a time until it succeeds or fails
  • C.A rule shell
  • D.A frame hierarchy, in which each frame inherits the slots defined by its parent frame

Answer: A

A blackboard holds an evolving solution that independent knowledge sources inspect and extend whenever they can contribute, coordinated by a control component. It suits problems with no fixed solution path, such as speech understanding, where HEARSAY-II introduced it. Chaining, shells and hierarchies are different concerns. The metaphor of specialists round a shared board is the clearest statement of the idea. Most errors here come from carrying a result across from a neighbouring case where it does not hold.
