# UD_Spanish-GSD

Treebank card from UD release 2.18: metadata and texts come from `UD_Spanish-GSD/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_Spanish-GSD](https://md.mova.elamur.ai/free/en/docs/treebanks/es/gsd/papers/); seeds: `seeds/`; converter: `convert.md`.

## Annotation layers

| Layer | Origin |
| --- | --- |
| Lemmas | automatic |
| UPOS | converted from manual |
| XPOS | not available |
| Features | automatic |
| Relations | converted from manual |

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

| dev | 1 400 | 36 461 | 37 151 | 688 | 0 |

| **total** | 16 013 | 423 225 | 431 478 | 8 236 | 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 Spanish UD is converted from the content head version of the [universal dependency treebank v2.0 (legacy)](https://github.com/ryanmcd/uni-dep-tb).

## Introduction

> In addition to converting dependencies from the legacy UD treebank, token level morphology features have been added automatically using the parsers/taggers in Bohnet et al (2014) and Bohnet et al. (2015) trained on the Ancora treebank and converted automatically to UD standards.
> 
> Various heuristics have been added to improve the output of the tagger, fix obvious errors and add features that the tagger did not supply. The changes for v1.2 (November 2015) were done by Miguel Ballesteros, Dan Zeman, and Héctor Martínez Alonso.
> 
> The Spanish UD conforms to the UD guidelines, but there are some exceptions.
