QUE: explanation through exploration

QUE, QUerying the Expert system, is designed to provide a collaborative exploratory environment for a variety of types of users of expert systems. Explanation in intelligent systems has long been the subject of research from a number of different approaches, each of which has shown promise as well as problems. This paper describes how QUE, which is currently under development, approaches the problem of providing explanation by providing tools for both developers and users that enable explanation and user understanding of the underlying expert system's reasoning.
