近年来，关于个人语言及其在法医作者分析中的作用，有很多理论上的讨论。这篇文章利用前美国能源公司安然的电子邮件数据，通过分析电子邮件中问候和告别两种惯例中作者独特的差异，提供了一项识别个人习语的实证调查。两个阶段的分析的第一部分确定了四作者语料库中区分作者的一些形式。使用似然比，第二阶段的分析发现，一些识别的问候和告别形式，以及形式的组合，在与126位作者的《安然发送的电子邮件作者参考语料库》进行测试时，仍然具有作者的独特和个性，并突出了不太频繁的变体的诊断能力。这篇文章的结果为涉及电子邮件的法医作者案件提供了理论和方法上的贡献，以及总体结果的基线。
Over recent years there has been much theoretical discussion regarding idiolect and its usefulness in forensic authorship analysis. This article, drawing on email data from the former American energy company Enron, offers an empirical investigation into identifying individuals’ idiolects through analysing author distinctive variation within two conventions of the email genre – greetings and farewells. The first part of a two-stage analysis identifies a number of forms which distinguish between authors in a four-author corpus. Using likelihood ratios, the second stage of analysis finds that some of the greeting and farewell forms identified, and combinations of forms, remain distinctive and individuating of their author when tested against the 126-author ‘Enron Sent Email Author Reference Corpus’, and highlights the diagnostic power of less frequent variants. The results from this article offer both theoretical and methodological contributions as well as a baseline of population results for forensic authorship casework involving emails.
