+# 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 columns are described in the columns 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` with the period renders the tagging as `NOUN+PUNCT`.
+
