Frequency control method and device in precise recommendation

Abstract

The invention discloses a frequency control method and device in precise recommendation. The frequency control method disclosed by the invention comprises the following steps: extracting video access log information recorded in a server to obtain terminal information of a video access terminal, information of a material accessed by the video access terminal and an access time of the video access terminal for accessing the material; correspondingly storing a terminal identifier, a material identifier and the access time; establishing an index structure, wherein the index structure is used for storing the corresponding terminal identifier and the material identifier when the access time exceeds a preset access upper limit within a preset time; and looking up the information of the material corresponding to a target terminal in the index structure, and filtering the found information of the material when releasing the material to the target terminal. According to the frequency control method disclosed by the invention, since a layer of index structure is added based on the one-layer Key-Value data structure, the query speed is greatly accelerated, therefore viewing experience of users can be effectively improved, the audience number is increased, and more viewers can see more materials.

Description

technical field [0001] The present invention relates to the field of computer video, in particular to a frequency control method and device in accurate recommendation. Background technique [0002] Frequency control is to control the maximum number of times a user sees a piece of material within a specified time, and is one of the core means of precise targeting technology. Wherein, the material may be an advertisement delivered by an advertisement delivery system or information pushed. For example, Publisher can limit a user to see the same material three times at most in one day (24 hours). Publisher is the person who advertises for the advertiser. The frequency control in this article is strict frequency control, that is, when the set upper limit is reached, the material will not be displayed at all. [0003] In precise recommendation, the higher the frequency, the better. On the one hand, too little contact will certainly not create an impression in the user's mind; o...

AI Technical Summary

Problems solved by technology

[0007] To sum up, the existing technology has the following defects: using the client-side cookie solution, the cookie becomes very heavy, and the amount of records is limited

Since the precise recommendation system needs to support multiple clients, such as Mobile-web (mobile-side web), app, etc., if the client-side solution is adopted, it needs to be modified in every place, and the cost is relatively high, while the server-side solution has good scalability , only one place needs to be modified, and there is no need to develop again for new promotion positions

In addition, the query speed of the existing delivery system is slow, which reduces the user experience
