Abstract—Recommender systems help Web users to address
information overload. Their performance, however, depends on
the amount of information that users provide about their preferences.
Users are not willing to provide information for a large
amount of items, thus the quality of recommendations is affected
specially for new users. Active learning has been proposed in the
past, to acquire preference information from users. Based on
an underlying prediction model, these approaches determine the
most informative item for querying the new user to provide a
rating. In this paper, we propose a new active learning method
which is developed specially based on aspect model features.
There is a difference between classic active learning and active
learning for recommender system.
