Problems solved by technology

Using the above sorting method, the feature values ​​of candidate content corresponding to some multimedia resources may be obtained from historical calculations. Since the updated feature set does not contain relevant features (or feature coverage may be incomplete or there is no intersection), the calculated sorting There is a certain bias in the results, which reduces the recommendation effect

Abstract

The invention relates to a multimedia resource recommendation ordering method and device. The method comprises the steps of acquiring first weight values corresponding to multimedia resource characteristics within a preset period according to clicking request feedback data generated within the preset period; fusing the first weight values corresponding to the multimedia resource characteristics with second weight values corresponding to the multimedia resource characteristics obtained from historical multimedia resource characteristic data, so that third weight values corresponding to the multimedia resource characteristics are obtained; ordering multimedia resources to be recommended according to the third weight values corresponding to the multimedia resource characteristics. By the adoption of the method, the multimedia resource characteristics are not lost, and each multimedia resource characteristic has a corresponding characteristic value; besides, the weight values of the multimedia resource characteristics are fused into historical weight values, the accuracy of an ordering result is improved, and high-quality multimedia resource recommending information is provided for users.

Description

technical field [0001] The invention relates to the field of multimedia, in particular to a method and device for recommending and sorting multimedia resources. Background technique [0002] The recommendation effect of multimedia resources is affected by many links. Wherein, the sorting link determines which candidate contents may become the final multimedia resource recommendation information and be displayed to the user. In the existing multimedia resource recommendation process, the multimedia resource information requested by users added within the preset period can be sorted out to obtain the training data required for model update, and then the updated feature set and weight value can be obtained by training the training data . [0003] In the prior art, due to the limitation of data magnitude and computing resources, it is difficult to process the multimedia resource information requested by users increased within a long preset period at one time. Therefore, in th...
