Material recommendation method and device, electronic equipment and storage medium

Abstract

The invention relates to a material recommendation method and device, electronic equipment and a storage medium. The method comprises the steps: acquiring multiple materials including an active material; according to the deviation between the current target exposure and the current accumulative exposure and the deviation between the historical target exposure and the historical accumulative exposure, obtaining the current exposure variable quantity of the active material; adjusting a historical weighting coefficient according to the current exposure variable quantity to obtain a current weighting coefficient; obtaining a target similarity according to a first similarity between the first material feature vector of the active material and the object feature vector of the target object and a current weighting coefficient; and according to the second similarity between the second material feature vectors of the other materials and the object feature vector and the target similarity, determining a target material which is recommended to the target object and comprises the active material from the plurality of materials. According to the invention, the recommendation sorting position of the active material is controlled through the current weighting coefficient, and accurate control of the exposure of the active material is realized.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a material recommendation method, device, electronic equipment and storage medium. Background technique [0002] Recommendation refers to recommending materials that the user is interested in based on the user's interest characteristics and historical behavior. But for a specific material, the number of times it is displayed to users depends on the ranking model of the recommendation system. In some application scenarios (such as some event scenes), it is necessary to precisely control the number of exposures of certain materials and to take into account the quality of the exposure. [0003] In the related technology, it is possible to select the most matching active material and insert it according to different users at a fixed position in the non-head of the recommendation list, but the position of the active material is fixed and cannot be sorted according to t...

Problems solved by technology

[0004] The present disclosure provides a material recommendation method, device, electronic equipment, and storage medium to at least solve the problem caused by the fixed position of the active material in the related art, which cannot achieve precise control of the exposure of the active material, thus making it impossible to ensure the completion of the active material. The problem with the total target impressions for
