Deciphering published articles on cyberterrorism: a latent Dirichlet allocation algorithm application

摘要

An emerging issue called cyberterrorism is a fatal problem causing a disturbance in the cyberspace. To unravel underlying issues about cyberterrorism, it is imperative to look into available documents found in the NATO's repository. Extraction of articles using web-mining technique and performed topic modelling on NLP. Moreover, this study employed latent Dirichlet allocation algorithm , an unsupervised machine learning to generate latent themes from the text corpus. An identified five underlying themes revealed based on the result. Finally, a profound understanding of cyberterrorism as a pragmatic menace of the cyberspace through a worldwide spread of black propaganda, recruitment, computer and network hacking, economic sabotage and others revealed. As a result, countries around the world, including NATO and its allies, had continuously improved its capabilities against cyberterrorism.
