Summary

The Brazilian Portuguese UD is converted from the Google Universal Dependency Treebank v2.0 (legacy).

Changelog

• 2023-10-31

• This treebank was not included in the last release, issue 36 fixes the errors and the data is valid again.

• we had ~11% of the corpus invalid according to validation script. Many errors remain from the annotations done back in UD 1.x guidelines. I (Alexandre) fixed the invalid sentences automatically, running UDPipe with the model trained from Bosque. The sentences were annnotated with extra metadata for further manual review.

• During the fixes, I also fixed tokenization and segmentation of few cases, so the number of sentences changed. New sentences got IDs with sufixes 'a', 'b' etc.

• 2022-11-01 v2.11

• added missing lemmas of NUM tokens

• start to fix the enclitics tokenization

• 2021-05-01 v2.8

• Fixed verbs that are not AUX in PT

• Fixed some cases of missing MWT (contractions)

• Fixed some other erros in validation.

• added many more missing lemmas

• removed undocumented subtypes "xcomp:adj" and "acl:part".

We still have many validation errors and incompatibilities with UD_Portuguese-Bosque.

• 2019-11-15 v2.5
  • 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).

2018-04-27 v2.3

• Added lemmas from MorphoBr project (https://github.com/LFG-PTBR/MorphoBr), see issue #8 for more details.
