Universal Dependencies
Universal Dependencies (UD) is a framework for cross-linguistically consistent grammatical annotation and an open community effort with over 200 contributors producing more than 100 treebanks in over 70 languages.
- Short introduction to UD
- UD annotation guidelines
- More information on UD:
- Query UD treebanks online:
- SETS treebank search maintained by the University of Turku
- PML Tree Query maintained by the Charles University in Prague
- Kontext maintained by the Charles University in Prague
- Grew-match maintained by Inria in Nancy
- Download UD treebanks
If you want to receive news about Universal Dependencies, you can subscribe to the UD mailing list. If you want to discuss individual annotation questions, use the Github issue tracker.
Current UD Languages
Information about language families (and genera for families with multiple branches) is mostly taken from WALS Online (IE = Indo-European).
