# UD CoNLL-U 2017 aligned

This dataset is a processed version of the dataset made available for the [UD CoNLL Shared Task 2017](http://universaldependencies.org/conll17/), entitled "Multilingual Parsing from Raw Text to Universal Dependencies." This task is based on the [Universal Dependencies 2.0 dataset](https://lindat.mff.cuni.cz/repository/items/1333f6f2-1627-4fa2-9b6d-e4c24456fe3d).

The processing aligns words and tokens along with their morphological annotations using the [universal part-of-speech set](https://universaldependencies.org/u/pos/) for sequence-to-sequence task training. 

The dataset fields are described in the table below:

|  Field |  Description                          |
| ------ | ------------------------------------- |
| `id`   |  Universal Dependencies submission ID |
| `lang` |  IETF language code (cf. [langcodes](https://github.com/georgkrause/langcodes)) |
| `text` |  Text sentence                        |
| `tags` |  Sequence of universal POS tags       |


## Sequence of Part-of-Speech tags

The sequence of POS tags is separated by spaces, but contiguity of words with punctuation
and contractions from combinations of words are marked by a `+` character. Example:

```
Text: You   won't     see   this section.
Tags: PRON  AUX+PART  VERB  DET  NOUN+PUNCT
```

Note that `won't`, as equivalent to `will+not`, is tagged as `AUX+PART` accordingly.
Also, the contiguity between `section` and the period renders the tagging as `NOUN+PUNCT`.
