Abstract

The invention discloses a portal personalized recommendation service system, which introduces an interest model feedback updating mechanism and refers to that: (A) an interest model feedback updating module is added to the A output end of a privacy protection unit; (B) information connection is established between the C output end of the privacy protection unit and a recommended selector; (C) a feedback updating algorithm set is added to a data storage unit, and the feedback updating algorithm set is used for the storage of interest model updating algorithm; wherein, the interest model feedback updating model consists of an interest drifting detection unit and an interest model updating unit. The portal personalized recommendation service system which introduces the interest model feedback updating mechanism solves the problem of interest drifting in the portal personalized recommendation service system, realizes the quick, accurate and stable updating of the interest model of a portal user, and provides for the user a personalized recommendation resource service which is closer to the interests of the user. The portal personalized recommendation service system of the invention can quickly response to the interest drifting of the portal user, thus realizing the efficient and accurate updating of the interest model of the user.

Description

technical field [0001] The present invention relates to portal (Portal) technology, and more particularly refers to a portal personalized recommendation service system that introduces an interest model feedback update mechanism. The portal personalized recommendation service system can solve the problem of degradation of personalized recommendation service quality caused by user interest drift. Background technique [0002] The invention patent with the patent application number of 200610098867.0 "A portal personalized recommendation service method and system using a meta-recommendation engine" proposes the construction of a portal user interest model, including the initial creation and subsequent update of the portal user interest model; The personalized recommendation service architecture of the recommendation engine is independent of the portal platform. The meta-recommendation engine can analyze the relationship between users and user groups and the changes in personaliz...
