# UD_Icelandic-GC

Treebank card from UD release 2.18: metadata and texts come from `UD_Icelandic-GC/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_Icelandic-GC](https://md.mova.elamur.ai/free/en/docs/treebanks/is/gc/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 | 3 960 | 78 568 | 78 568 | 0 | 0 |
| dev | 500 | 10 694 | 10 694 | 0 | 0 |
| test | 540 | 10 349 | 10 349 | 0 | 0 |
| **total** | 5 000 | 99 611 | 99 611 | 0 | 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

> UD_Icelandic-GC is a conversion of the gold part of [GreynirCorpus](https://github.com/mideind/GreynirCorpus), which has been manually corrected and verified. The corpus is parsed into full constituency trees, and converted using [UDConverter-GreynirCorpus](https://github.com/thorunna/UDConverter-GreynirCorpus).

## Introduction

> The treebank consists of text which was extracted from news and governments sites on the web in the years 2015-2021.
> 
> The GreynirCorpus data was split into a development set and a test set, and that split is preserved. The test set consists of 10% of the total number of sentences, chosen at random. The test set in UD_Icelandic-GC is the same. The original development set is now the training set, excluding every tenth file, which is now in the development set.
> 
> The treebank consists of 99,611 tokens in total. The training set consists of 78,568 tokens, the development set of 10,694 tokens and the test set of 10,349 tokens.
