Problems solved by technology

[0003] 1) Vectorize the live room according to the viewing sequence, and make recommendations based on the similarity between the obtained vectors, but this kind of recommendation based on the similarity between vectors is very difficult to calculate when the live room is very large in magnitude
[0004] 2) Based on Markov's principle, the most likely viewing path of the user is predicted through the transition probability, but the data noise of the user's transition behavior is very strong, and there may be no necessary similarity between transferring from the same live broadcast room to other live broadcast rooms

Abstract

The embodiment of the invention provides a live broadcast room recommendation method and a related device, which are used for quickly recommending a live broadcast room to a user. The method comprisesthe steps: obtaining a user watching sequence of a live broadcast platform in a preset time period; determining a transfer weight between live broadcast rooms in the live broadcast platform accordingto the user watching sequence; determining a first directed graph of the live broadcast platform according to the transfer weight between the live broadcast rooms in the live broadcast platform; cutting the first directed graph based on a preset out-degree and / or a preset in-degree to obtain a second directed graph; calculating the transition probability of each node in the second directed graph;calculating the target arrival probability of each node in the second directed graph according to the transition probability of each node in the second directed graph; determining live broadcast roomclustering of the live broadcast platform in a preset time period based on the target arrival probability of each node in the second directed graph; and recommending a live broadcast room to the target user according to a set of live broadcast rooms watched by the target user in the preset time period and the live broadcast room clustering of the live broadcast platform.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a method for recommending a live broadcast room and related equipment. Background technique [0002] There is a sequence in the user's viewing behavior of the live broadcast room on the live broadcast platform, so each user has a viewing path of the live broadcast room, which reflects when the user watched which live broadcast room. Common recommendation methods based on user viewing paths are as follows: [0003] 1) Vectorize the live room according to the viewing sequence, and make recommendations based on the similarity between the obtained vectors, but this kind of recommendation based on the similarity between vectors is very difficult to calculate when the live room is very large in magnitude. [0004] 2) Based on Markov's principle, the most likely viewing path of the user is predicted through the transition probability, but the data noise of the us...
