- It depends greatly on whom you ask (and what you call an expert system).
- Here is an excerpt from my upcoming Intro AI text:
-
- How many successfully fielded expert systems are there? It depends on
- whom you ask. Of the three that we have mentioned, R1 and the
- oil-well tool were successfully delivered to their corporate sponsors;
- MYCIN has not been put into actual use. Ed Feigenbaum will tell you
- that there are on the order of 5000 successfully fielded expert
- systems; Hubert Dreyfus, one of AI's leading critics, has said that
- there are about five fielded systems, and only four of those make
- money. A decade ago, \cite{Feigenbaum:fifth} listed forty-three
- ``selected experimental and operational expert systems,'' of which six
- were described as operational. Two of these six were medical systems
- that have, to the best of my knowledge, never been used clinically.
-
- I, too, would appreciate hearing about any definitive answer. Thanks!
