Embodiment Construction

[0037] The specific implementation process of the present invention will be described below by taking user interest modeling in a music network forum as an example. The methods of user modeling in other similar scenarios are consistent, and the method of the present invention should not be construed as being limited to this embodiment.

[0038] figure 1 A schematic diagram of the invention is given. The present invention establishes the user's individual interest model and group interest model respectively from the situation that the user participates in the object discussion, and then fuses the two interest models. During specific implementation, the present invention will be divided into 5 main steps, as figure 2 As shown, the order is as follows: 1) Establish user-object bipartite graph network; 2) Calculate user individual interest; 3) Calculate social relationship between users; 4) Calculate user group interest; 5) Combine individual interest and group interest to obta...

Abstract

The invention discloses a method for establishing a user interest model. In the method, on the basis of constructing an user individual interest model, a social coordination relationship among users is calculated by utilizing behavior characteristics of the users, a group interest model of the users is established by taking a quantization value of the relationship as a weight, and finally the group interest model is fused with the individual interest model to form the final interest mode. The method can be used for user modeling in various personalized pushing services, such as personalized news and book recommendation, in application such as Internet and an E-commerce system.

Description

technical field [0001] The invention relates to user interest modeling technology in personalized service. Background technique [0002] The status and importance of personalized service in today's economic and social life are increasingly prominent. For example, search engines on the Internet need to provide personalized search results, news websites need to provide personalized news, e-commerce needs to recommend personalized goods and services, mobile communications need to recommend personalized tariff packages and new services, etc. Wait. By providing personalized services, maximizing the satisfaction of user needs, cultivating user stickiness and loyalty, and ultimately, service providers will benefit. [0003] The core of personalized service is to match the needs of users, in which user interest modeling is the key. [0004] In the prior art, a typical method of user interest modeling is text content analysis. For example, by tracking the webpages visited by user...
