This paper introduces the Grievance Dictionary, a psycholinguistic dictionary that can be used to automatically understand language use in the context of grievance-fueled violence threat assessment. We describe the development of the dictionary, which was informed by suggestions from experienced threat assessment practitioners. These suggestions and subsequent human and computational word list generation resulted in a dictionary of 20,502 words annotated by 2318 participants. The dictionary was validated by applying it to texts written by violent and non-violent individuals, showing strong evidence for a difference between populations in several dictionary categories. Further classification tasks showed promising performance, but future improvements are still needed. Finally, we provide instructions and suggestions for the use of the Grievance Dictionary by security professionals and (violence) researchers.
本文介绍了“怨愤词典”，这是一种心理语言学词典，可以用于在与怨愤相关的暴力威胁评估语境下自动理解语言使用。我们描述了词典的开发过程，该过程得到了有经验的威胁评估从业者的建议。这些建议以及随后的人工和计算词汇表生成，产生了一个包含 20502 个单词的词典，由 2318 名参与者进行了注释。通过将词典应用于暴力和非暴力个体所写的文本，该词典得到了验证，表明在几个词典类别中，群体之间存在明显差异。进一步的分类任务显示出有希望的性能，但仍需要进一步改进。最后，我们为安全专业人员和（暴力）研究人员提供了使用“怨愤词典”的说明和建议。
