Problems solved by technology

[0005] When there are many live broadcast objects, a large amount of labor is required to monitor the text data of each live broadcast object, which not only greatly increases the operating cost, but also has low work efficiency and accuracy in manual monitoring and extraction of live topic samples

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0030] see figure 1 As shown, the live topic sample extraction method in the embodiment of the present invention includes the following steps:

[0031] S1: In HIVE (non-relational database), the server uses the database query statement to obtain the text data information of the live object that needs to extract the live topic sample within the specified period (at least 15 days, 1 month in this embodiment), text The data information includes at least 2 groups of sub-text data information (so that it can be classified and managed later), and each group of sub-text data information includes sub-text data objects and corresponding text information, and then go to S2.

[0032] The live broadcast object in S1 is the live broadcast platform, live broadcast room or live broadcast user:

[0033] When the live broadcast object is a live broadcast pla...

Abstract

The invention discloses a live broadcast subject sample extraction method, storage medium, electronic device and system, which relate to the live broadcast live comment filtering field. The method comprises the following steps: acquiring text data information of a live broadcast object in a specified period; setting live broadcast theme samples that appear in the text information, and saving all live broadcast theme samples to form a sample vocabulary; in the text information of each sub-text data object, counting the occurrence times corresponding to each live broadcast topic sample to form the live broadcast sample vector of the text data object. All the live broadcast sample vectors are added together to obtain the live broadcast topic sample vectors and weighted values are obtained byweighted calculation. When extracting the live broadcast subject sample, the invention can remarkably reduce the operation cost and greatly improve the work efficiency and the work precision. It can also provide powerful support for the statistics, identification and other processing of the sample of the subsequent live broadcast theme.

Description

technical field [0001] The invention relates to the field of live barrage filtering, in particular to a method for extracting live topic samples, a storage medium, electronic equipment and a system. Background technique [0002] With the rapid development of the live broadcast industry, more and more users like to watch live broadcasts. In order to improve user experience, the live broadcast platform sets a live broadcast theme for each live broadcast object (such as the live broadcast platform, live broadcast room and live broadcast users). In order to finely summarize and manage the live broadcast topics, the live broadcast platform will extract live broadcast topic samples for each live broadcast object according to the live broadcast topics. [0003] At present, the existing methods for extracting live topic samples of each live object according to the live topic are generally: manually monitor the text data (ie barrage) of the live object within a specified period, and...
