Leveraging tagging for neighborhood-aware probabilistic matrix factorization

Le Wu, Enhong Chen, Qi Liu, Linli Xu, Tengfei Bao, Lei Zhang
2012 Proceedings of the 21st ACM international conference on Information and knowledge management - CIKM '12  
Generally, two kinds of approaches to CF, the local neighborhood methods and the global matrix factorization models, have been widely studied.  ...  To that end, in this paper, by leveraging the extra tagging data, we propose a novel unified two-stage recommendation framework, named Neighborhood-aware Probabilistic Matrix Factorization(NHPMF).  ...  Obviously, there are complementary advantages for local neighborhood methods and the global matrix factorization models, and for making better recommendation it is necessary to combine the local information  ...
