TagMF

TagMF represents an interactive recommending approach that merges user-generated tags with latent factors derived from user ratings to increase user profile transparency and interactive control in Recommender Systems. Taking advantage of the Matrix Factorization technique widely used in Collaborative Filtering, the method learns an integrated model of tags and latent factors, thus enabling users to understand and manipulate their preference profile expressed implicitly in the (intransparent) latent factor space through explicitly presented textual tags.
