# UD_Polish-PDB

Treebank card from UD release 2.18: metadata and texts come from `UD_Polish-PDB/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_Polish-PDB](https://md.mova.elamur.ai/free/en/docs/treebanks/pl/pdb/papers/); seeds: `seeds/`; converter: `convert.md`.

## Annotation layers

| Layer | Origin |
| --- | --- |
| Lemmas | converted from manual |
| UPOS | converted from manual |
| XPOS | manual native |
| Features | converted from manual |
| 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 | 2 215 | 34 423 | 34 677 | 235 | 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 Polish PDB-UD treebank is automatically converted from the Polish Dependency Bank 2.0 (PDB 2.0). Both treebanks were created at the [Institute of Computer Science, Polish Academy of Sciences](https://ipipan.waw.pl/en/) in Warsaw (Poland).

## Introduction

> The PDB-UD treebank consists of 22,152 sentences (350K tokens) from [Polish National Corpus](http://nkjp.pl), [Europarl](http://www.statmt.org/europarl), [DGT-Translation Memory](https://ec.europa.eu/jrc/en/language-technologies/dgt-translation-memory), [OPUS](http://opus.nlpl.eu), [Pelcra Parallel Corpus](http://metashare.dfki.de/repository/browse/pelcra-polish-english-parallel-corpus-of-literary-works-cc-by/e99fa4c063f111e2bff4525400d761472dc239ffeb6f47bda0553af53ddd5ef0/), [CDSCorpus](http://zil.ipipan.waw.pl/Scwad/CDSCorpus) and literature. PDB-UD is an extended and corrected version of the Polish SZ-UD treebank (release 1.2 to 2.3).
> 
> The morphological, syntactic and semantic annotation of the PDB-UD treebank is rule-based, converted from PDB 2.0 data.
> 
> The PDB-UD treebank contains enhanced graphs, i.e. trees with enhanced edges encoding the shared dependents and the shared governors of coordinated conjuncts (9141 PDB-UD trees contain enhanced edges).
