Abstract
A user model is defined as a knowledge in natural-language dialog system swhich contains explicit assumptions on all aspects of the user that may be relevant to the dialogue behaviour of the system. This paper shows the structure and the use of two user models exploited in ALFRESCO, a multimodal natural language-centered system for information exploration. The user's knowledge model, or UK, is based on an initialization, depending on a user profile, an on a modelization of qhat the user has become aware of so far. The user's interest model, or UI, provides a model of the potential interest of the userFile in questo prodotto:
