Since Labov's (1964) foundational work on the social stratification of language, linguistics has dedicated concerted efforts towards understanding the relationships between socio-demographic factors and language production and perception. Despite the large body of evidence identifying significant relationships between socio-demographic factors and language production, relatively few of these factors have been investigated in the context of NLP technology. While age and gender are well covered, Labov's initial target, socio-economic class, is largely absent. We survey the existing Natural Language Processing (NLP) literature and find that only 20 papers even mention socio-economic status. However, the majority of those papers do not engage with class beyond collecting information of annotator-demographics. Given this research lacuna, we provide a definition of class that can be operationalised by NLP researchers, and argue for including socio-economic class in future language technologies.

在自然语言处理技术中，虽然已经研究了年龄和性别等方面与语言产生之间的关系，但至今较少研究 社会经济阶级等因素。本研究通过对现有自然语言处理文献进行调查，发现只有20篇论文提及社会经济阶级，并且大多数论文仅限于收集注释者人口统计信息，而未深入研究该阶级。鉴于此项研究空白，我们提供了一个可在自然语言处理研究中操作的社会经济阶级定义，并主张在今后的语言技术中应包含社会经济阶级。
