Treebank card from UD release 2.18: metadata and texts come from `UD_Shanghainese-ShUD/README.md`; size is counted by streaming the `.conllu` files and checked against the release `stats.xml`. Generated by `tools/treebanks build`; do not edit by hand.

| Layer | Origin |
| --- | --- |
| Lemmas | manual native |
| UPOS | manual native |
| XPOS | not available |
| Features | manual native |
| Relations | manual native |

UD scale: *manual native* — annotated by hand directly in UD; *converted from manual* — converted from manual annotation in another scheme; *converted with corrections* — converted and partly corrected by hand; *automatic with corrections* — automatic, with partial manual corrections; *automatic* — automatic; *not available* — the layer is absent.

## Size

| Split | Sentences | Tokens | Words | Multiword tokens | Empty nodes |
| --- | --- | --- | --- | --- | --- |
| train | 786 | 6 827 | 6 827 | 0 | 0 |
| dev | 98 | 883 | 883 | 0 | 0 |
| test | 99 | 874 | 874 | 0 | 0 |
| **total** | 983 | 8 584 | 8 584 | 0 | 0 |

Tokens are surface tokens (Spanish `vámonos` is one), words are syntactic words (`vamos` + `nos`); multiword tokens are those split into several words; empty nodes are the `N.M` nodes of the enhanced graph.

## Summary

> **UD Shanghainese-ShUD** is the first UD treebank for Shanghainese.

## Introduction

> **UD Shanghainese-ShUD** is the first UD treebank for Shanghainese, a Wu Chinese variant spoken by approximately 14 million people. This treebank is annotated from a corpus with a focus on daily-use speech, which is a representative sample of contemporary Shanghainese. For details on the annotation method and pipelines, see the [paper](https://aclanthology.org/2025.udw-1.20/). Sentences are randomly split to train, test, and dev by ratios of 80%, 10%, 10%, respectively.
> 
> Shanghainese includes several geographical and historical variants. The focus of this treebank is on Middle and New Period Urban Shanghainese.
