Personalized recommendation in Collaborative Tagging Systems — •Zi-Ke ZHANG — chemin du musee, CH1700, Fribourg, Switzerland

Personalized recommender systems are confronting great challenges of accuracy, diversification and novelty, especially when the data set is sparse and lacks accessorial information, such as user profiles, item attributes and explicit ratings. Collaborative tags contain rich information about personalized preferences and item contents. We are trying to find an efficient yet simple way to make use of tags to provide better recommendations.
