- I agree, it definitely does depend on what you call an expert system. And
- on what is meant by "successfully fielded". The state of Minnesota is
- currently using a system that I wrote using a commercial expert system shell
- in order to rate soils with regard to degree of pesticide run-off and
- leaching, using data collected from the state-wide soil surveys. Does this
- count? (Are we up to six now Dreyfus? I'm sure he'd find a reason to
- discount it. Perhaps because it works.)
