Phototyping as a design strategy and as a means of knowledge acquisition: an assessment using the Piloting Expert System
One of the outstanding problems in constructing expert systems is that of knowledge acquisition. There is a scarcity of well-documented empirical research in the area of knowledge acquisition, and far fewer guidelines for effecting the process. This research evaluates prototyping as an expert systems design strategy, and as a means of knowledge acquisition. This research describes an empirical knowledge acquisition experiment that provides a framework for determining what types of heuristics can be elicited through different means of knowledge acquisition. The research is a first step in a long-term research plan focused on developing guidelines for effecting knowledge acquisition. A second problem with much expert systems research has been the lack of evaluation of such systems. The second experiment evaluates the decision-support contribution provided to naive decision makers by the prototype Piloting Expert System in an on-line, operational scenario.
