Embodiment 1

[0033] Such as figure 1 As shown, the social robot identification method of the present invention, the steps are as follows:

[0034] Step (1), collect a certain piece of content posted by some users on Weibo within one day and the mutual comment relationship, and the number of accounts is about 3000. Record the content posted by an account on the social platform, and collect the substantive comment content and comments posted by the comment account under the content at the same time. At the same time, judge whether the account is a robot based on the content posted by the account and the comment relationship.

[0035] figure 2 It is a schematic diagram of the social network in the present invention.

[0036] Step (2), performing natural language processing on the substantive content published by all collected accounts to obtain a data set. Firstly, high-frequency words such as "de" and "yes" are removed. Then select about 1500 commonly used words and arrange them in a c...

Abstract

The invention provides a social robot recognition method based on a graph attention network. The method of the present invention is based on the graph attention network, by performing natural language processing on the content published on the social network to construct node features, forwarding and commenting relationships between social accounts to construct a graph, and then classifying, thereby judging whether the account is a social robot. First, social network data is created to create a data set, and then the graph attention network is constructed, and the graph attention network is trained and tested through the created data set. Aiming at the problem of complex social network robot identification, the method of the present invention can automatically and efficiently identify social robots, reduce opportunities for criminals to take advantage of, thereby limiting speech released by robots, weakening the influence of bad public opinion, and helping to maintain social harmony and stability.

Description

technical field [0001] The present invention relates to the application field of the graph attention network, in particular to the node classification technology based on the graph attention network and its actual application to the field of social networks. Background technique [0002] In recent years, with the development of social networks, individuals can fully express their voices on the Internet, but it also gives criminals an opportunity to publish bad content on the Internet. Especially on Weibo, which is full of trolls and zombie fans, social robots can publish a large amount of content to influence the direction of public opinion. Therefore, a system is needed to identify social robots and control the social impact of the speeches released by robots. [0003] In computer science, a graph is a data structure consisting of vertices and edges. A graph G can be described by a set of vertices V and the edges E it contains, namely: [0004] G=(V,E) (1) [0005] Verti...
