虽然恐怖主义信息学研究审查了极端主义媒体的技术构成，但审查此类媒体背后的内容和意图的工作较少。我们认为，极端主义媒体中提出的论点和问题提供了对作者意图的洞察，这反过来可能为检测和评估风险提供证据基础。我们通过对由于2008/2009年以色列在加沙和西岸领土上的军事行动而煽动暴力的50篇在线文本应用两种定量文本分析方法来探讨这一可能性。第一种方法--一种识别说服性工具出现的内容编码系统--揭示了文本中道德证明论点的优势，以及不同作者和不同群体背景下可区分的说服力使用情况的证据。第二种方法--确定作者使用的核心概念和叙述的语料库语言技术--证实了使用道德证据来制造组内/组外的分歧，同时也展示了随着冲突的加剧，从一般的不满表达到更直接的面向受众的暴力表达的运动。我们的结论是，多方法分析是一种有价值的方法，既可以建立对恐怖主义媒体使用的循证理解，也可以在恐怖主义信息学中建立一套有效的应用程序。
While terrorism informatics research has examined the technical composition of extremist media, there is less work examining the content and intent behind such media. We propose that the arguments and issues presented in extremist media provide insights into authors’ intent, which in turn may provide an evidence-base for detecting and assessing risk. We explore this possibility by applying two quantitative text-analysis methods to 50 online texts that incite violence as a result of the 2008/2009 Israeli military action in Gaza and the West Bank territories. The first method—a content coding system that identifies the occurrence of persuasive devices—revealed a predominance of moral proof arguments within the texts, and evidence for distinguishable ‘profiles’ of persuasion use across different authors and different group affiliations. The second method—a corpus-linguistic technique that identifies the core concepts and narratives that authors use—confirmed the use of moral proof to create an in-group/out-group divide, while also demonstrating a movement from general expressions of discontent to more direct audience-orientated expressions of violence as conflict heightened. We conclude that multi-method analyses are a valuable approach to building both an evidence-based understanding of terrorist media use and a valid set of applications within terrorist informatics.
