Embodiment 1

[0056] This embodiment provides a method for identifying garbage barrage, such as figure 1 As shown, the method includes:

[0057] S101. Based on the preset barrage information feature construction rules, perform feature extraction on the barrage information to obtain first barrage information;

[0058] In this step, before performing feature extraction on the bullet chat information, it is necessary to use the database query statement SQL to extract the bullet chat information marked with the type of bullet chat from the relational database HIVE as sample data. The barrage information includes barrage content and barrage type.

[0059] Then, based on the preset barrage information feature construction rules, feature extraction is performed on the barrage information to obtain the first barrage information. The feature construction rule includes: using a specific identifier to represent a word conforming to a certain type of feature.

[0060] Specifically, because there are...

Embodiment 2

[0092] Corresponding to Embodiment 1, this embodiment provides a device for identifying spam barrage, such as figure 2 As shown, the device includes: extraction unit 21, preprocessing unit 22, word segmentation unit 23, conversion unit 24, weighting unit 25, establishment unit 26 and judgment unit 27; wherein,

[0093] Before the extraction unit 21 performs feature extraction on the bullet chat information, it is necessary to use the database query statement SQL to extract the bullet chat information marked with the bullet chat type as sample data from the relational database HIVE. The barrage information includes barrage content and barrage type.

[0094] Then the extracting unit 21 performs feature extraction on the bullet chat information based on the preset bullet chat information feature construction rules to obtain the first bullet chat information. The feature construction rule includes: using a specific identifier to represent a word conforming to a certain type of f...

Embodiment 3

[0122] The present embodiment also provides a kind of computer equipment of rubbish barrage identification, such as image 3 As shown, the computer device includes: a radio frequency (Radio Frequency, RF) circuit 310, a memory 320, an input unit 330, a display unit 340, an audio circuit 350, a WiFi module 360, a processor 370, and a power supply 380 and other components. Those skilled in the art can understand that, image 3 The structure of the computer device shown in the computer device does not constitute a limitation to the computer device, and may include more or less components than those shown in the illustration, or combine some components, or arrange different components.

[0123] Combine below image 3 A detailed introduction to each component of computer equipment:

[0124] The RF circuit 310 can be used for receiving and sending signals, especially, after receiving the downlink information of the base station, the processor 350 processes it. Generally, the RF c...

Abstract

The present invention provides a method and an apparatus for recognizing a junk barrage, and a computer device. The method comprises: on the basis of a preset barrage information feature construction rule, performing feature extraction to acquire first barrage information; according to a word-forming rule in a self-defined word library on a live-streaming platform, performing word-cutting on the first barrage information, to construct a bag-of-words model; on the basis of a preset mapping rule, converting the bag-of-words model into a word vector; performing term frequency-inverse document frequency (TF-IDF) weighting on each word in the word vector, to acquire the TF-IDF weighted value of each word; establishing a Naïve Bayes model, and on the basis of the TF-IDF weighted value of each word, using the Naïve Bayes model to calculate a first probability that the barrage information is a junk barrage and a second probability that the barrage information is a normal barrage in the case where all words appear; and determining whether the first probability is greater than the second probability, and if the first probability is greater than the second probability, determining that the barrage information is a junk barrage.

Description

technical field [0001] The invention belongs to the technical field of garbage barrage processing on a live broadcast platform, and in particular relates to a garbage barrage identification method, device and computer equipment. Background technique [0002] At present, with the rapid development of the live broadcast industry, the audience of live broadcasts is also constantly expanding, and various types of live broadcast content are becoming more and more abundant. Viewers can participate in comments and interactions by sending barrage while watching the live broadcast, which greatly improves user participation and enriches the live broadcast content. [0003] Generally speaking, every time a viewer sends a barrage, the barrage will be sent to the server of the live broadcast platform, and the server of the live broadcast platform will forward the barrage to all viewers in the live broadcast room. However, in order to obtain benefits, some abnormal users often burst out ...
