An Attention-Based Graph Neural Network for Spam Bot Detection in Social Networks

Abstract: With the rapid development of social networks, spam bots and other anomaly accounts’ malicious behavior has become a critical information security problem threatening the social network platform. In order to reduce this threat, the existing research mainly uses feature-based detection or propagation-based detection, and it applies machine learning or graph mining algorithms to identify anomaly accounts in social networks. However, with the development of technology, spam bots are becoming more advanced, and id… Show more

“…According to the feature analysis, the detection methods (Adewole et al , 2017) can be divided into: (1) methods based on social network analysis, involving analyzing the topological social structure of the accounts within the network or extracting discriminative network features to detect social bots (Mendoza et al , 2020; Lingam et al. , 2019; Zhao et al , 2020); (2) methods based on content and behavioral analysis, involving distinguishing social bots from humans through profile information, textual features, URL features, topic/mention/retweet features, posting time features, sentiment features, etc. (Cai et al.…”

“…According to the detection technologies, the existing social bot detection methods include (Orabi et al, 2020): (1) graph-based methods (Ahmed and Abulaish, 2013;Dorri et al, 2018); (2) machine learning-based methods, including the approach of supervised learning (Alarifi et al, 2016;Chu et al, 2012;Kudugunta and Ferrara, 2018), unsupervised learning (Ahmed and Abulaish, 2013;Cresci et al, 2018) and semi-supervised learning (Dorri et al, 2018;Shi et al, 2019); (3) crowdsourcing-based methods (Wang et al, 2012;Cresci et al, 2017); and (4) anomaly-based methods (Wang and Paschalidis, 2017;Costa et al, 2017;Pan et al, 2016).

“…In addition to these works based on supervised and unsupervised approaches, present studies utilize a semisupervised method to identify social bots. Zhao et al [30] present a semi-supervised model founded on a attention mechanism-based graph CNN, which spots spam bots by integrating many user characteristics and relational structures. To detect counterfeit accounts from a vast volume of Twitter data, BalaAnand et al [31] presented an enhanced graph-based semi-supervised learning algorithm (EGSLA).…”

“…Zhao et al [68] introduced a semi-supervised graph embedding model to detect spam bot for the directed social network, where they used the attention mechanism and graph neural network to detect spam bot based on the retweet relationship and the following relationship between users. They experimented with the Twitter 1KS-10KN dataset [69] which was collected on Twitter, compared with GCN, GraphSAGE, and GAT, their method achieved the best performance in Recall, Precision, and F1-score.…”
