Privileged contextual information for context-aware recommender systems

作者：

Highlights：

• WA method that treats additional information as virtual items in recommender systems.

• The method is instantiated in three different algorithms for recommender systems.

• The algorithms are evaluated among themselves and against the state-of-the-art.

• Results show that the proposal improves the predictive ability of the recommenders.
