User Modeling: The Long and Winding Road

Abstract

The long and winding road of user modeling is grounded in different episte-mological assumptions exploring different dimensions of the problem. User-modeling research has explored different domains, identified important distinctions underlying different approaches within user modeling research, and created a number of challenging research problems. These issues are explored in the context of high-functionality applications and how our research over the last ten years has addressed the problems of making high-functionality applications more usable, more useful, and more learnable with a variety of different user modeling approaches.
