Abstract

Explanation systems supply information that clarifies the structure and problem domain of a computer program for the user. We begin our paper by describing the early explanation systems, which were built for expert system programs, and by reviewing some of the subsequent developments in artificial intelligence that relate to this area. The results of our research are consistent with some of the recent developments in artificial intelligence; we have found that there are a variety of kinds of information that are useful to naive users of computer programs. We have been particularly interested in writing programs that can supply such information to naive users of numerical computer simulations. We describe an implemented explanation system, NATURALIST, which explains the structure and domain of a simulation for inventory control. Our experience with the NATURALIST program suggests that explanation facilities may be valuable additions to numerical computer simulations.
