- W4385486570 abstract "Much work in the literature has studied different types of cyber security related users and communities on OSNs, such as activists, hacktivists, hackers, cyber criminals. A few studies also covered no-expert users who discussed cyber security related topics, however, to the best of our knowledge, none has studied activities of cyber security researchers on OSNs. This paper fills this gap using a data-driven analysis of the presence of the UK’s Academic Centres of Excellence in Cyber Security Research (ACEs-CSR) on Twitter. We created machine learning classifiers to identify cyber security and research related accounts. Then, starting from 19 seed accounts of the ACEs-CSR, a social network graph of 1,817 research-related accounts that were followers or friends of at least one ACE-CSR was constructed. We conducted a comprehensive analysis of the data we collected: a social structural analysis of the social graph; a topic modelling analysis to identify the main topics discussed publicly by researchers in ACEs-CSR network, and a sentiment analysis of how researchers perceived the ACE-CSR programme and the ACEs-CSR. Our study revealed several findings: 1) graph-based analysis and community detection algorithms are useful in detecting sub-communities of researchers to help understand how they are formed and what they represent; 2) topic modelling can identify topics discussed by cyber security researchers (e.g., cyber security incidents, vulnerabilities, threats, privacy, data protection laws, cryptography, research, education, cyber conflict, and politics); and 3) sentiment analysis showed a generally positive sentiment about the ACE-CSR programme and ACEs-CSR. Our work showed the feasibility and usefulness of large-scale automated analyses of cyber security researchers on Twitter." @default.
