Abstract
User modeling issues are examined in the context of a user-adapted guidance system. The system provides users with instructions about natural tasks without introducing a special time-consuming sub-dialog to learn the user's knowledge. A model for providing such guidance is developed on the basis of a phenomenological analysis of human guidance, and illustrated by a system that gives directions in geographical domains. The main features of the user model design include: (1) Bothimplicit andexplicit acquisition methods are employed in a flexible manner; (2) The guidance instructions and the user model are generated incrementally and interchangeably; (3) User's responses and no-responses are employed as a source of information for the user modeling. The model and the resulting system's performance are examined in light of recent development in the cognitive literature.

Also served as a visiting professor at Cornell University and Swarthmore College, as a visiting fellow at Princeton University, and as a visiting scholar at the center of interdisciplinary Research of the University of Bielefeld and at the Rockefeller Foundation Study center in Bellagio. Research interest focus on the conceptual foundation of cognitive science, the phenomenology of human conscious mentation, and on the psychology of creativity. A monograph presenting a comprehensive critique of the representational view of mind and a search for alternatives to it is forthcoming.
