NLP-Based Techniques for Cyber Threat Intelligence
In the digital era, threat actors employ sophisticated techniques for which,
often, digital traces in the form of textual data are available. Cyber Threat
Intelligence~(CTI) is related to all the solutions inherent to data collection,
processing, and analysis useful to understand a threat actor's targets and
attack behavior. Currently, CTI is assuming an always more crucial role in
identifying and mitigating threats and enabling proactive defense strategies.
In this context, NLP, an artificial intelligence branch, has emerged as a
powerful tool for enhancing threat intelligence capabilities. This survey paper
provides a comprehensive overview of NLP-based techniques applied in the
context of threat intelligence. It begins by describing the foundational
definitions and principles of CTI as a major tool for safeguarding digital
assets. It then undertakes a thorough examination of NLP-based techniques for
CTI data crawling from Web sources, CTI data analysis, Relation Extraction from
cybersecurity data, CTI sharing and collaboration, and security threats of CTI.
Finally, the challenges and limitations of NLP in threat intelligence are
exhaustively examined, including data quality issues and ethical
considerations. This survey draws a complete framework and serves as a valuable
resource for security professionals and researchers seeking to understand the
state-of-the-art NLP-based threat intelligence techniques and their potential
impact on cybersecurity
Attention Restraint, Working Memory Capacity, and Mind Wandering: Do Emotional Valence or Intentionality Matter?
Attention restraint appears to mediate the relationship between working memory capacity (WMC) and mind wandering (Kane et al., 2016). Prior work has identifed two dimensions of mind wandering—emotional valence and intentionality. However, less is known about how WMC and attention restraint correlate with these dimensions. Te current study examined the relationship between WMC, attention restraint, and mind wandering by emotional valence and intentionality. A confrmatory factor analysis demonstrated that WMC and attention restraint were strongly correlated, but only attention restraint was related to overall mind wandering, consistent with prior fndings. However, when examining the emotional valence of mind wandering, attention restraint and WMC were related to negatively and positively valenced, but not neutral, mind wandering. Attention restraint was also related to intentional but not unintentional mind wandering. Tese results suggest that WMC and attention restraint predict some, but not all, types of mind wandering

Can structural priming answer the important questions about language? A commentary on Branigan and Pickering "An experimental approach to linguistic representation"
While structural priming makes a valuable contribution to psycholinguistics, it does not allow direct observation of representation, nor escape “source ambiguity.” Structural priming taps into implicit memory representations and processes that may differ from what is used online. We question whether implicit memory for language can and should be equated with linguistic representation or with language processing
