Ponomarev A.V. Incorporating context into collaborative ltering systems: a survey. Abstract. It is recognized that incorporating context information into recommender systems is one of the most eective ways to increase their quality and predictive abilities. The paper surveys primary methods of enhancing collaborative ltering systems by taking actual context information into account. The focus is mostly on dierent avours of contextual pre-ltering and matrix factorization approaches which are the most popular and promising.
