Abstract

The embodiments of the invention provide a multimedia resource recommendation method and system. The method comprises the steps of establishing a text vector matrix and a tag vector matrix corresponding to a multimedia library; acquiring a text reduction matrix of the text vector matrix and a tag reduction matrix of the tag vector matrix; when determining a current multimedia file played by a user, determining the multimedia similarity degrees between the current multimedia file and other multimedia files in the multimedia library according to the text reduction matrix and the tag reduction matrix; according to the multimedia similarity degrees corresponding to the multimedia files in the multimedia library, determining the multimedia files to be recommended to users as to-be-recommended resources. The method solves the problem of cold boot in a multimedia resource recommendation process and solves the problem of influence of text synonyms and polysemy on multimedia file similarity degree calculation in a multimedia resource recommendation process, so that the multimedia file matching degree is increased and the accuracy of multimedia resource recommendation is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of Internet multimedia technologies, and in particular to a method and system for recommending multimedia resources. Background technique [0002] At present, with the development of Internet technology, there have been many multimedia playback products for users. The multimedia playback products can provide users with the required multimedia resources. In order to make the multimedia playback products designed by themselves can be favored by more users , while providing the required multimedia resources for the user, other functions serving the user are also added, for example, recommending more multimedia resources that the user likes to the user. [0003] Generally, a collaborative filtering algorithm is usually used to implement the recommendation of multimedia resources. The implementation process is described as follows: first, the merchant needs to collect the co-occurrence relationshi...
