User preferences became recently a hot topic. The massive use of internet shops and social webs require the presence of a user mod- elling, which helps users to orient them selfs on a page.
There are many different approaches to model user preferences. In this paper, we will overview the current state-of-the-art in the area of acquisition of user preferences and their induction.
Main focus will be on the models of user preferences and on the induction of these models, but also the process of extracting preferences from the user behaviour will be studied. We will also present our contribution to the probabilistic user models.
