Knowledge acquisition for medical diagnosis systems

摘要

The methodology of the development of knowledge bases for expert systems is based on questioning of human experts. Until now, very little attention has been paid to the question of the consistency and accuracy of the expert's estimations. This is a subject of great importance, especially in areas requiring the estimation of probability events. In the research partially presented in the paper, a multistage methodology was developed to elicit knowledge requiring subjective judgement. The paper discusses an empirical application in the field of medical diagnosis, and includes the results and conclusions drawn from it.
