In contrast to many decades of research on oral code-switching, the study of
written multilingual productions has only recently enjoyed a surge of interest.
Many open questions remain regarding the sociolinguistic underpinnings of
written code-switching, and progress has been limited by a lack of suitable
resources. We introduce a novel, large, and diverse dataset of written
code-switched productions, curated from topical threads of multiple bilingual
communities on the Reddit discussion platform, and explore questions that were
mainly addressed in the context of spoken language thus far. We investigate
whether findings in oral code-switching concerning content and style, as well
as speaker proficiency, are carried over into written code-switching in
discussion forums. The released dataset can further facilitate a range of
research and practical activities.

该研究介绍了一种新的、大规模和多样化的数据集，这个数据集是从 Reddit 的多个双语社区的主题帖中精选而来的书面混合语言产品，探讨了至今主要在口语语言背景下讨论的内容和风格、发言者的熟练程度等问题是否也能适用于书面语混合，该数据集可以进一步促进一系列研究和实际活动。
