Abstract

This paper discusses user modelling techniques and presents the design and implementation of the 3M user modelling interface of INTEREX. INTEREX is an expert system for X-ray topographic image interpretation which assists its users in identifying and analysing a number of defects that can occur in high-quality crystals. 3M consists of a MONITOR, a MODEL and a MODIFIER. It is used to adapt the consultation route and the explanation is provided by INTEREX to three categories of users. It demonstrates the use of an implicit, individual, dynamic and long-term user model to enable an expert system to accommodate users with different levels of expertise.
