Abstract

Aiming at the problem of low accuracy in the use of traditional recommendation algorithm in mobile environment, this paper proposed a matrix factorization algorithm based on context-aware. Based on the basic matrix factorization algorithm, the algorithm performed unknown score prediction by incorporating global bias and context bias. The advantage of this algorithm was that: on the one hand, it used the matrix factorization to make the scale of the matrix much smaller than the original scoring matrix; on the other hand, the algorithm fully integrated the influence of the situational elements on the score, making the prediction score more accurate. Experiments on the LDOS-CoMoDa dataset show that the proposed algorithm outperforms the user-based collaborative filtering algorithm, the basic matrix factorization algorithm and baseline prediction algorithm.
