A joint framework for collaborative and content filtering

Justin Basilico, Thomas Hofmann
2004 Proceedings of the 27th annual international conference on Research and development in information retrieval - SIGIR '04  
This paper proposes a novel, unified, and systematic approach to combine collaborative and content-based filtering for ranking and user preference prediction.  ...  The framework incorporates all available information by coupling together multiple learning problems and using a suitable kernel or similarity function between user-item pairs.  ...  We pursue the philosophy that collaborative and content-based filtering are complementary views that should be unified in a common learning architecture.  ...
