Multi-media file recommendation method and recommendation server

The invention provides a multi-media file recommendation method and a recommendation server. The method comprises the following steps that the recommendation server obtains N pieces of multi-media playing behavior information of N users, wherein N is a positive integer; the recommendation server clusters the N users according to the N multi-media playing behavior information so as to obtain M user groups, wherein M is a positive integer and is smaller than N; the recommendation server obtains multi-media playing behavior information of users to whom multi-media files are to be recommended, obtains user groups corresponding to the users to whom the multi-media files are to be recommended according to the multi-media playing behavior information, and recommends corresponding multi-media files to the users to whom the multi-media files are to be recommended according to the user groups. According to the multi-media file recommendation method, the problems that a multi-media file recommendation result is diverse, and the recommended multi-media files are not uniform in style and are not consistent with the preference of the users to whom the multi-media files are to be recommended are solved, the recommendation result is more stable, the influence caused by data sparsity and user playing behavior arbitrariness on the recommendation result is small, and user experience is improved.
