Hi!
This is Yang Qizhen from Shanghai, China.
I speak Shanghainese, Mandarin, and English.
I am interested in linguistics, computer science, natural language processing (NLP), cryptocurrency, mathematics, anthropology, typography, ultimate frisbee, and visual arts.
Not only that, I am also a big fan of self-hosted and corp-free services. I believe we should all expel intrusive corporation products that do not act in favour of us. Everyone should live a sustainable and private digital life and enjoy the right to be forgotten.

ShUD: the First Shanghainese Universal Dependency Treebank
Read Paper »
Treebank included in the Universal Dependencies project; Accepted paper in UD Workshop 2025 (part of SyntaxFest 2025, an ACL-affiliated conference, in Ljubljana, 26–29 August 2025)
Treebank included in the Universal Dependencies project; Accepted paper in UD Workshop 2025 (part of SyntaxFest 2025, an ACL-affiliated conference, in Ljubljana, 26–29 August 2025)
Abstract
This paper introduces ShUD, the first Universal Dependencies (UD) treebank for Shanghainese, a Wu Chinese variant spoken by approximately 14 million people but severely under-resourced in NLP. The treebank is built through a scalable annotation pipeline that exploits grammatical parallels between Shanghainese and Mandarin. Our pipeline also provides a practical strategy for bootstrapping resources for other Chinese dialects. We documented syntactic phenomena unique to Shanghainese within the UD framework and fine-tuned a dependency parser using our annotated treebank, contributing a foundation to both NLP tool development and cross-linguistic syntactic research.
