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) Both implicit and explicit 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.
