Explaining Complex Engineered Devices.

Abstract

This paper presents the outline of an algorithm which generates summary explanations of and answers questions about complex engineered devices. The algorithm uses two domain models: an expert model of the machine, and a model of the student's device understanding. Also required is an inference engine which can perform qualitative simulations of the device engine from the expert model. Given these prerequisites, the algorithm recursively describes the device in a series of ever more detailed passes. In each pass the device is depicted with a strict sequence of topics: the device's role, function, structure, and then its mechanism. The explanatory algorithm is interesting not only for its potential utility in computer aided instruction but also for the constraints it sets on the contents of an expert tutor's mental model of an engineered device.
