This study analyzes the usage of Japanese gendered language on Twitter. Starting from a collection of 408 million Japanese tweets from 2015 till 2019 and an additional sample of 2355 manually classified Twitter accounts timelines into gender and categories (politicians, musicians, etc). A large scale textual analysis is performed on this corpus to identify and examine sentence-final particles (SFPs) and first-person pronouns appearing in the texts. It turns out that gendered language is in fact used also on Twitter, in about 6% of the tweets, and that the prescriptive classification into "male" and "female" language does not always meet the expectations, with remarkable exceptions. Further, SFPs and pronouns show increasing or decreasing trends, indicating an evolution of the language used on Twitter.

Twitter 上是否使用了日语中的性别语言？大规模研究

本研究分析了日本性别语言在 Twitter 上的使用情况。从 2015 年到 2019 年的 4.08 亿条日本推文的集合以及 2355 个手动将 Twitter 帐户时间线分类为性别和类别（政治家、音乐家等）的额外样本。对该语料库进行大规模的文本分析，以识别和检查文本中出现的句末助词 (SFP) 和第一人称代词。事实证明，Twitter 上实际上也使用了性别语言，大约 6% 的推文中使用了性别化语言，并且“男性”和“女性”语言的规定性分类并不总是符合预期，除了显着的例外。此外，SFP 和代词显示出增加或减少的趋势，表明 Twitter 上使用的语言发生了演变。
