IPTV program recommendation method

Abstract

The invention discloses an IPTV program recommendation method. The method comprises the steps of building a user rating matrix according to a watching log of a user; sequentially performing low-rank denoising, periodic compression and watching mode extraction on the user rating matrix, so as to obtain a periodic watching scene of the user; using each watching mode in the periodic watching scene as an interest user, and building a score matrix of all interest users; and identifying a current watching mode so as to determine a current interest user, recommending programs that the user is interested in from a historical film bank and current live programs by using a joint recommendation policy, generating a recommendation list and pushing the recommendation list to the user. The method can well handle the multi-member condition at an IPTV terminal, improving the recommendation precision. In addition, a live and on-demand combined recommendation policy is adopted, so that the user can acquire more comprehensive recommended content.
