Method and system for discovering media account in specific region on social platform

Abstract

The invention provides a method and a system for discovering a media account in a specific region on a social platform. An inventor discovers that high-quality seed media account information is difficult to quickly obtain by an existing method when a media account in a specific region on a social platform discovers a task, thus a set of method for quickly labeling a seed media account is designed, and the method comprises the steps of determining candidate accounts and classifying the accounts. The inventor finds that the feature design of the existing method has the problems of weak features, incapability of reflecting the features of the media account, difficulty in large-scale implementation and the like, so that the feature extraction method aiming at the features of the media account is designed. The method is high in speed and strong in extracted features. The inventor finds that the existing method is difficult to expand from the seed account to more media accounts in a high-efficiency and high-quality manner. Therefore, on the basis of solving seed account marking and feature extraction methods, two complementary expansion methods are designed to obtain high-quality and high-quantity media accounts.

Description

technical field [0001] The invention belongs to the field of data mining, and in particular relates to a method and system for discovering media accounts in a specific region on a social platform. Background technique [0002] With the rise of social platforms, more and more traditional media have begun to migrate their main information dissemination channels from newspapers, radio and television to social platforms. The process of information digitization has also spawned a large number of new-generation digital media, which were born on the Internet and use their official websites, mobile applications, and social platform accounts as the main channels for information dissemination. At the same time, the development of social platforms has fueled the desire for personal expression. More and more users share their knowledge and insights in certain fields on social media and become self-media. Media accounts on social platforms are high-quality information acquisition channe...

AI Technical Summary

Problems solved by technology

Techniques 3, 4, and 5 are all based on acquired media accounts, and there is no effective means to discover media accounts; in addition, in terms of feature mining, the features proposed by Technique 3 are too weak, and the features proposed by Technique 4 are based on specific fields. Neither feature can be applied to media account discovery

The feature extraction method proposed in Technology 5 is difficult to apply to the massive user database of social platforms, and cannot solve the task of media account discovery
