## Annotation layers

| Layer | Origin |
| --- | --- |
| Lemmas | manual native |
| UPOS | manual native |
| XPOS | manual native |
| Features | manual native |
| 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 |

| dev | 979 | 12 023 | 12 289 | 266 | 0 |

| **total** | 9 761 | 121 835 | 125 212 | 3 374 | 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 Turkish dependency treebank annotated in UD style. Created by the members of [TABILAB](https://tabilab.cmpe.boun.edu.tr/) from Boğaziçi University.

## Introduction

> This is a Turkish dependency treebank in the Universal Dependencies (UD) annotation style. The BOUN Treebank is created by [TABILAB](https://tabilab.cmpe.boun.edu.tr/) and supported by the Scientific and Technological Research Council of Turkey (TÜBİTAK) under grant number 117E971.
> 
> The BOUN Treebank includes a total of 9,761 manually annotated sentences from various topics including biographical texts, national newspapers, instructional texts, popular culture articles, and essays. The texts are taken from the [Turkish National Corpus (TNC)](https://www.tnc.org.tr/).
> 
> The dependency relations in the BOUN Treebank are manually annotated in the UD framework. The morphological features and UPOS information are first retrieved from the morphological parser of [Sak et al. (2011)](https://link.springer.com/article/10.1007/s10579-010-9128-6) and converted to UD morphology automatically using [our script](https://github.com/boun-tabi/UD_docs/blob/main/convert_sak_morp_to_ud_morp.py). The morphological features, UPOS tags, XPOS tags, and lemma forms are then manually corrected in a systematic way.
