Default Reasoning and Stereotypes in User Modelling
September 1, 1988
This article discusses the application of various kinds of default reasoning in systems which must maintain a model of its users. In particular, we describe a general architecture of a domain-independent system for building and maintaining long-term models of individual users. The user modelling system is intended to provide a well-defined set of services for an application system that interacts with various users and needs to build and maintain models of them. As the application system interacts with a user, it can acquire knowledge of him and pass that knowledge on to the user model maintenance system for incorporation. We describe a prototype general user modelling system (hereafter called GUMS1) which we have implemented in Prolog. This system satisfies some of the desirable characteristics we discuss.
