| 6th Knowledge Acquisition for Knowledge Based Systems Workshop. |
|
| A major problem with building expert systems is that experts always communicate knowledge in a specific context. A knowledge acquisition methodology has been developed which restricts the use of knowledge to the context in which it was provided. This method, "ripple down rules" allows for extremely rapid and simple knowledge acquisition where the time required to incorporate each new piece of knowledge remains constant regardless of the size of the knowledge base. An expert system based on this approach and built by experts without the help of a knowledge engineer is now in routine use. This paper reviews what has been achieved using the approach, its problems and potential. |
