ABSTRACT
There are two major categories of research that address the role of questions during knowledge acquisition when expert systems are developed. The first category focuses on the questions that a knowledge engineer should ask an expert to best elicit the expert's knowledge. The second examines the questions that experts ask. LaFrance (1988) has enumerated the types of questions that knowledge engineers should ask experts. Lauer and Peacock (chap. 13 in this volume) have examined the questions that individual auditors asked about three scenarios and have compared the profiles of questions asked by different experts. We adopted an approach similar to that of Lauer and Peacock. That is, we analyzed the questions asked by experts. However, instead of comparing profiles of questions asked by individual experts, we compared the profiles of questions experts asked about typical versus troublesome cases. We also compared the questions experts asked with the profiles of questions in successive prototype programs.
