Embodiment Construction

[0057] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0058] The social cloud media collaborative filtering recommendation method of the present invention, such as figure 1 shown, including the following steps:

[0059] Step 1: Obtain microblogs sent by multiple microblog users and associated users who have social relationships with these microblog users.

[0060] Step 2: According to the microblogs sent by microblog users obtained in step 1, construct a user-item rating matrix for reflecting the corresponding relationship between different users' ratings for different items.

[0061] In step 2, the construction method of the user-item rating matrix is ​​as follows: extract all the content that the user is interested in from the microblog obtained in step 1, including movies, music, books, etc., to construct an item set; Whether the blog involves items in the project set, and the evalu...

Abstract

The invention relates to a social association cloud media collaborative filtering and recommending method. The method includes the following steps that micro blogs sent by multiple micro blog users and associated users of the micro blog users are obtained; a user program rating matrix for reflecting the corresponding relation between different users and grading of different programs is built; influence grading of the associated users on the programs is calculated; the feature vector of the micro log users is calculated; feature similarity of the micro log users is calculated; the influence grading of similar users similar to the micro log users on the programs is calculated; the user program grading matrix is updated according to the influence grading of the associated users on the programs and the influence grading of the similar users on the programs; network resources are explored, and the updated user program grading matrix is expanded; cluster is conducted on the user program grading matrix based on the users and the programs respectively; class cluster obtained through the cluster serves as a neighbor search domain, and grading is predicted through collaborative filtering and recommending. By means of the method, network information content which interests the users can be accurately recommended for the users.

Description

technical field [0001] The invention relates to the technical field of network information push, in particular to a social cloud media collaborative filtering recommendation method applied to a social network. Background technique [0002] The purpose of the recommendation system is to establish a connection between users and information. On the one hand, it helps users find information that is meaningful to them; . Through the analysis of user data in social networks, users' topic interests and trust relationships among users can be obtained. And the corresponding media service provider can recommend books, audio and video, products, etc. to users in a targeted manner through this analysis. For the information provider, this improves the accuracy of pushing information, and for the user, more accurate information can be obtained, helping the user to improve the efficiency of obtaining information. [0003] The basic assumption of the collaborative filtering recommendatio...
