Abstract

The invention discloses a mixed personalized recommendation method, which comprises the following steps that: obtaining film and television metadata capable of being recommended; carrying out similarfilm and television retrieval to obtain a candidate film and television; through sorting weight, carrying out similar sorting on candidate films and televisions; carrying out user behavior clustering,and generating a mixed recommendation candidate film and television according to a clustering result; and after all candidate films and televisions are sorted for multiple times, obtaining a recommendation result used for displaying. User behaviors are clustered to establish a user portrait, the user portrait obtained by clustering is used for generating the recommendation result, and personalized recommendation is carried out on the basis of the short-term watching historical behavior of the user and a hot broadcast film library, wherein films, television plays, variety shows and the like are mixed in the recommendation result. On the basis of content recommendation, the method is free from the influence of user-film incidence matrix sparseness problems, is explanatory and has a recommendation effect.

Description

technical field [0001] The invention relates to the field of television video, in particular to a hybrid personalized recommendation method. Background technique [0002] There are many recommendation algorithms in the recommendation system, and there are many mature algorithms like collaborative filtering, but they cannot fully meet the needs in different application scenarios and based on different data applications. When using videos from the entire network as recommended content, it is inevitable to encounter the problem of sparse user-video correlation matrix. Contents of the invention [0003] In view of the above-mentioned shortcomings existing at present, the present invention provides a hybrid personalized recommendation method, which can perform hybrid personalized recommendation based on the user's short-term viewing history behavior and popular movie library. [0004] In order to achieve the above object, embodiments of the present invention adopt the followin...
