Abstract

This paper is about providingintelligent help to users interacting with anoperating system. Its main focus is an investigationof Human Plausible Reasoning Theory (Collins &Michalski, 1989) to infer the commands the user shouldhave typed, given what they did type. The theory hasbeen adapted and incorporated into a prototypeIntelligent Help System (IHS) for UNIX users, calledRESCUER, and has been used for the generation andevaluation of hypotheses about users‘ beliefsunderlying the observed users‘ actions on the UNIXfile store. The hypotheses generated by RESCUER werecompared to those made by human experts on the samplescripts from UNIX user sessions. The potential forHuman Plausible Reasoning as a mechanism to reasonabout slips and misconceptions is discussed.
