Social-bots-mediated information manipulation is influencing the public opinion environment, and their role and behavior patterns in news proliferation are worth exploring. Based on the analysis of bots' posting frequency, influence, and retweeting relationship, we take the diffusion of The New York Times' coverage of Xinjiang issue on the overseas social platform Twitter as an example and employ the two-step flow model. It is found that in the role of second-step diffusion, unlike posting news indiscriminately in first-step diffusion, social bots are more inclined to postcontroversial information in second-step diffusion; in terms of diffusion patterns, although social bots are more engaged in first-step diffusion than in second-step diffusion and can trigger human users to retweet, they are still inferior to humans in terms of influence.

With the support of technology in the new era, the terrorism activities present many new characteristics. An increasing number of terrorist organizations use new media to promote extreme ideas, release terrorism information, recruit group participants and plot terrorist activities. Besides the hard power, we should also use soft power to disorganize the terrorism's foundation in terms of thoughts and public opinions. Therefore, introducing the communication has great significance to counter-terrorism. We can establish the national counter-terrorism strategic communication mechanism and fuse the work with politics, diploma, national-defense, religion and so on. Therefore, the information resource and other resource can be deeply reorganized and the counter-terrorism efficiency can be enhanced.

[Purpose / Significance] The crisis of misinformation will increase in 5G.The spread of terrorism-related information in sudden violent and terrorist incidents in social networks has a great impact on national security and counter-terrorism work.

[Methods/Procedures] Based on the social network analysis method and analyzing the communication characteristic of terrorism-related information and the factors of intervention, this paper proposed an intervention mechanism for terror-related information based on online social network. The proposed mechanism consists of three aspects: communication topic, communication structure and opinion leaders. [Results/Conclusion] The study finds out that we should strengthen the role of opinion leaders in information diffusion of news and government media, in terrorist incident, the network structure is loose and free on the whole, the spread of information influences the network structure and interaction. Government should supervise a real-time control on information emotional trend and hot topic according to different types of network structure characteristics, guiding the positive information and cooling down the harmful ones.
