Summary

Simplified Chinese Universal Dependencies dataset converted from the GSD (traditional) dataset with manual corrections.

Introduction

This is a simplified Chinese version of the UD Chinese GSD treebank. It is initially automatically converted into simplified Chinese with the OpenCC tool with patterns for mapping punctuation, then corrected with manual fixes.

Changelog

  • 2021-05-15 v2.8
    • Changed mark:relcl to mark:rel (as in the other Chinese treebanks).
    • Removed the relation case:dec (for 的 between two nouns; the other treebanks use just case here).
    • Removed the relation aux:aspect (the aspect particles 了 (le), 过 (guo), 着 (zhe) use just aux in the other treebanks).
    • Question particles changed from Mood=Inter to PartType=Int, and from discourse to discourse:sp.
    • Undocumented relation subtypes case:pref and case:suff changed to case.
    • Extent constructions converted from cop + mark:comp to compound:ext.
    • Changed mark:advb to mark:adv (as in the other Chinese treebanks).
  • 2020-11-15 v2.7
    • Aspect markers relations are corrected from case:aspect to aux:aspect.
  • 2019-11-15 v2.5
    • Initial release in Universal Dependencies, converted from UD_Chinese-GSD.
    • Google gave permission to drop the "NC" restriction from the license. This applies to the UD annotations (not the underlying content, of which Google claims no ownership or copyright).
    • Fixed punctuation (use East Asian punctuation where appropriate)
    • Fixed various parses and features (e.g., added Case=Ord)
    • Some manual fixes in tokenization
