Recommender Systems apply machine learning and data mining techniques for ﬁltering un- seen information and can predict whether a user would like a given resource. To date a number of rec- ommendation algorithms have been proposed, where collaborative ﬁltering and content-based ﬁltering are the two most famous and adopted recommendation techniques. Collaborative ﬁltering recommender sys- tems recommend items by identifying other users with similar taste and use their opinions for recom- mendation; whereas content-based recommender sys- tems recommend items based on the content informa- tion of the items. These systems suﬀer from scalabil- ity, data sparsity, over specialization, and cold-start problems resulting in poor quality recommendations and reduced coverage. Hybrid recommender systems combine individual systems to avoid certain afore- mentioned limitations of these systems. In this paper, we proposed a unique switching hybrid recommenda- tion approach by combining a Naive Bayes classiﬁca- tion approach with the collaborative ﬁltering. Exper- imental results on two diﬀerent data sets, show that the proposed algorithm is scalable and provide better performance–in terms of accuracy and coverage–than other algorithms while at the same time eliminates some recorded problems with the recommender sys- tems.
