# UD_Irish-IDT

Treebank card from UD release 2.18: metadata and texts come from `UD_Irish-IDT/README.txt`; 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_Irish-IDT](https://md.mova.elamur.ai/free/en/docs/treebanks/ga/idt/papers/); seeds: `seeds/`; converter: `convert.md`.

## Annotation layers

| Layer | Origin |
| --- | --- |
| Lemmas | manual native |
| UPOS | manual native |
| XPOS | manual native |
| Features | automatic with corrections |
| Relations | manual native |

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 | 4 005 | 95 881 | 95 881 | 0 | 0 |
| dev | 451 | 10 000 | 10 000 | 0 | 0 |
| test | 454 | 10 109 | 10 109 | 0 | 0 |
| **total** | 4 910 | 115 990 | 115 990 | 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

> A Universal Dependencies 4910-sentence treebank for modern Irish.

## Introduction

> The Irish UD Treebank (IUDT) is a conversion of the Irish Dependency Treebank (IDT), which was part of a PhD research project by Teresa Lynn at Dublin City University, Ireland (Lynn, 2016).
> 
> ---- The (smaller) IDT dataset has also been released on [GitHub] ([github.com/tlynn747/IrishDependencyTreebank](https://github.com/tlynn747/IrishDependencyTreebank)). ----
> 
> The Treebank contains 4910 sentences.
> 
> The first 2924 of which were taken from the New Corpus of Ireland-Irish (NCII), with text from books, newswire, websites and other media. These sentences are a subset of a gold-standard POS-tagged corpus for Irish made available by Elaine Uí Dhonnchadha of Trinity College Dublin. ----
> 
> The subsequent 1986 sentences were taken from a corpus of Irish public administration translations and are available under the Open Data (PSI) directive for sharing of pubic data: Citizens information website: (20%) Dublin City Council (DCC): (25%) DEpartment of Culture, Heritage and the Gaeltacht (DCHG):(9%) Udaras na Gaeltachta: (25%) EUbookshop: (21%)
> 
> The conversion from the IDT annotation scheme to the UD annotation scheme for the first release (1020 IDT trees) was designed by Teresa Lynn and Jennifer Foster at Dublin City University, Ireland. The mapping to UD is reported in Lynn et al., (2016) Conversion of sentences 1-1020 was automatic, with manual review. Subsequent updates or changes have been a combination of automatic labelling and manual review. All trees with sentence ID greater than 1021 were created through an automatic pre-parsing approach followed by manual review.
> 
> The UD Treebank is split into two sets as follows:
> 
> - 454 trees (test)
> - 451 trees (dev)
> - 4005 trees (train)
> 
> Note: the 451 dev trees were taken from the set of newly annotated trees in the v2.5 release. Selection of test sentences haven't changed since v1.0 (but annotations and quality have!)
