Prior work has applied NLP to perform several tasks for the cybersecurity domain, including privacy policy analysis (Peng et al., 2012; Pandita et al., 2013; Zhu and Dumitras, 2016), text analysis for cybersecurity with social media text (i.e., DDos attack detection, alert generation for threads and vulnerabilities using Twitter) (Mittal et al., 2016; Wang and Zhang, 2017; Sceller et al., 2017; Chambers et al., 2018; Perera et al., 2018; Alguliyev et al., 2019; Hasan et al., 2019), and report and timeline creation of cybersecurity events (Hackmageddon, 2019; PrivacyRight, 2019).
none of these work considers the detection of event trigger words from cybersecurity articles as we do.
