Embodiment

[0035] The present invention is based on the network live broadcast supervision method of bullet chat semantic analysis, wherein the bullet chat refers to the bullet chat sentence input by the audience displayed in real time on the video content played in the live broadcast room. The control text refers to the barrage text set recorded at that time in the live broadcast room containing sensitive content pre-selected by the administrator based on previous management experience, and there can be multiple control texts. The topic form generated by the LDA topic model is to obtain the probability distribution of the topic in mathematics.

[0036] Such as figure 1 As shown, the present invention is based on the network broadcast supervision method of barrage semantic analysis, comprising the following steps:

[0037] 1. Barrage crawling and preprocessing in the live broadcast room.

[0038] Such as figure 2 As shown, after crawling the barrage text from the webcast room, take 5...

Abstract

The invention discloses a barrage semantic analysis-based network direct broadcast supervision method. The method comprises the steps of crawling a barrage of a direct broadcast room in real time, and performing preprocessing; performing word segmentation processing on a barrage statement, removing stop words, building an LDA topic model, and extracting an implicit topic of the barrage; and performing similarity comparison on the obtained topic and sensitive topics to identity a specific sensitive topic. The sensitive topic can be automatically identified and an early warning is given to an administrator, so that the efficiency of network direct broadcast platform supervision is improved, the labor management cost is reduced, and the reliability and timeliness of supervision are improved; and the method is simple and efficient.

Description

technical field [0001] The invention belongs to the technical field of video content supervision, and in particular relates to a network live broadcast supervision method based on barrage semantic analysis. Background technique [0002] The webcast industry is a new Internet cultural industry that has developed rapidly in recent years. The barrage sharing website is one of the important forms. The video is played in the live broadcast room, the audience watches online, and the anchor and the audience communicate through the barrage. Among the more famous live broadcast platforms are Douyu, Huya, Quanmin, Panda, Zhanqi, YY, etc. According to statistics, in 2016 alone, there were nearly 200 online live broadcasting platforms nationwide, the market size of online live broadcasting was about 9 billion, and the number of users of online live broadcasting platforms had reached 325 million. There are more than 3,000 live rooms on one platform at the same time. [0003] A notable...
