User Modelling in a Dialog System

Abstract

In people’s home the amount of on-line available digital content such as video, music, or pictures is rapidly increasing. First home server products are available. Efficient selection of content will be a problem for users. We developed a flexible multimodal dialog system to overcome this. A keycomponent is the user model, which learns very fast from user behaviour. All information like key-words are determined automatically and scored according to their relevance. No manual setting is required.
