Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0029] see figure 1 As shown, the entropy method-based user partition preference calculation method in the embodiment of the present invention includes the following process:

[0030] S1: When users who need to calculate user partition preferences watch live video, according to user behavior information for different partitions, construct partition preference evaluation indicators for each user in each partition; evaluation indicators include effective viewing times and effective viewing time , The number of effective viewing rooms, the number of effective viewing days, the number of barrage, the number of barrage rooms, the number of days of barrage, the amount of gifts, the number of rooms with gifts, and the number of days with gifts.

[0031] The specific process of S1 is:

[0032] S101: According to the user's behavior information on di...

Abstract

The invention discloses a user partition preference calculation method and system based on the entropy method, and relates to the field of user partitions in live videos. The calculation method includes the steps that evaluation indexes are established in all partitions for all users; an initial matrix X is established according to the evaluation indexes of all the users; the optimum index X'zj of the j evaluation index of the z user is calculated in the initial matrix, and the contribution degree Pzj of the z user under the j evaluation index is calculated according to X'zj; the entropy ej of the j evaluation index is calculated according to Pzj; the diversity factor gj of the j evaluation index is calculated according to ej; the weight Wj of the j evaluation index is calculated according to gj; the preference scores of the users in all the partitions are calculated according to the weights of all the evaluation indexes. By means of the calculation method and system, the main partition types preferred by the users can be determined according to the preference scores of the users in different partitions.

Description

technical field [0001] The present invention relates to the field of user partitions in live video broadcasting, in particular to a method and system for calculating user partition preferences based on an entropy value method. Background technique [0002] With the enrichment of live video platform content, users need more personalized and accurate information acquisition means to quickly obtain the room content they are interested in. In order to achieve this goal, it is necessary to mine the interests of platform users and obtain the user's preferred content. [0003] When users watch live video on the live broadcast platform, they may watch a large number of partitioned content; users have different behaviors for different partitioned content, such as the number of rooms in the viewing partition, the length of viewing time, the frequency of viewing, and whether there are gifts. Information, etc., all reflect the user's preference for the content of the partition. Howeve...
