Abstract

The embodiment of the invention provides a method and a device for clustering multimedia data, relates to the software technical field, and solves the problem that a terminal in the existing technology cannot exactly cluster a user and a video. The method comprises: a step of obtaining attribute information of the multimedia data, wherein an element Rij of the matrix R represents whether an user I watches a multimedia data j, and an element Sab of the matrix S represents a similarity between a multimedia data a and a multimedia data b according to an attribute information matrix R and a matrix S; and a step of clustering all users and all multimedia data to obtain a matrix Y according to the matrix R, the matrix S and a matrix F, wherein an element Fxy of the matrix F represents whether an user x and an user y are friends; an element Ygl of the matrix Y represents that a multimedia data g belongs to a weighted value of a group l.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a multimedia data clustering method and device. Background technique [0002] Nowadays, in this era of rapid Internet development, people have higher and higher demand for audio-visual services, and the video-related recommendation service can recommend videos for users, effectively help users discover their needs, and promote users' demand for audio-visual services. In the prior art, a collaborative filtering recommendation (Collaborative Filtering, CF for short) algorithm is usually used to recommend videos for users. [0003] In the prior art, when a terminal (taking a smart TV as an example) recommends a video to a user according to the traditional CF algorithm, it usually uses a clustering algorithm to separate the TV videos stored in the database of the terminal backend server and the videos to watch according to the category of the video. The users of these videos are c...
