# UD_Galician-CTG

Treebank card from UD release 2.18: metadata and texts come from `UD_Galician-CTG/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. Papers: [Papers: UD_Galician-CTG](https://md.mova.elamur.ai/free/en/docs/treebanks/gl/ctg/papers/); seeds: `seeds/`; converter: `convert.md`.

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 | 2 272 | 71 928 | 79 507 | 7 529 | 0 |
| dev | 860 | 27 009 | 29 825 | 2 802 | 0 |
| test | 861 | 27 074 | 29 790 | 2 704 | 0 |
| **total** | 3 993 | 126 011 | 139 122 | 13 035 | 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

> The Galician UD treebank is based on the automatic parsing of the Galician Technical Corpus ([sli.uvigo.gal/CTG](http://sli.uvigo.gal/CTG)) created at the University of Vigo by the the TALG NLP research group.

## Introduction

> Original corpus sentences were selected and shuffled at random, and divided in 60-20-20 splits for the train, dev and test files, respectively.
> 
> The bootstrap version of the CTG UD annotated corpus was obtained by using FreeLing 4.0 parser with the Treeler library, and by adapting the POS and dependency relations tags to CoNLL-U Format. Next versions of the corpus imply a review of the results of this initial version.
> 
> The Galician UD treebank covers mainly technical texts of the fields of medicine, sociology, ecology, economy and law.
