	## Dataset Description
	- Website: https://github.com/UniversalDependencies/UD_Catalan-AnCora
	- Point of Contact: [Daniel Zeman](zeman@ufal.mff.cuni.cz)


	### Dataset Summary

	This dataset is composed of the annotations from the [AnCora corpus](http://clic.ub.edu/corpus/), projected on the [Universal Dependencies treebank](https://universaldependencies.org/). We use the POS annotations of this corpus as part of the [Catalan Language Understanding Benchmark (CLUB)](https://club.aina.bsc.es/).

	### Supported Tasks and Leaderboards

	POS tagging

	### Languages

	The dataset is in Catalan (`ca-ES`)

	## Dataset Structure

	### Data Instances

	Three conllu files.

	Annotations are encoded in plain text files (UTF-8, normalized to NFC, using only the LF character as line break, including an LF character at the end of file) with three types of lines:

	1) Word lines containing the annotation of a word/token in 10 fields separated by single tab characters (see below).
	2) Blank lines marking sentence boundaries.
	3) Comment lines starting with hash (#).

	### Data Fields
	Word lines contain the following fields:

	1) ID: Word index, integer starting at 1 for each new sentence; may be a range for multiword tokens; may be a decimal number for empty nodes (decimal numbers can be lower than 1 but must be greater than 0).
	2) FORM: Word form or punctuation symbol.
	3) LEMMA: Lemma or stem of word form.
	4) UPOS: Universal part-of-speech tag.
	5) XPOS: Language-specific part-of-speech tag; underscore if not available.
	6) FEATS: List of morphological features from the universal feature inventory or from a defined language-specific extension; underscore if not available.
	7) HEAD: Head of the current word, which is either a value of ID or zero (0).
	8) DEPREL: Universal dependency relation to the HEAD (root iff HEAD = 0) or a defined language-specific subtype of one.
	9) DEPS: Enhanced dependency graph in the form of a list of head-deprel pairs.
	10) MISC: Any other annotation.

	## Dataset Creation

	### Curation Rationale
	[N/A]

	### Source Data

	- [UD_Catalan-AnCora](https://github.com/UniversalDependencies/UD_Catalan-AnCora)

	#### Initial Data Collection and Normalization

	The original annotation was done in a constituency framework as a part of the [AnCora project](http://clic.ub.edu/corpus/) at the University of Barcelona. It was converted to dependencies by the [Universal Dependencies team](https://universaldependencies.org/) and used in the CoNLL 2009 shared task. The CoNLL 2009 version was later converted to HamleDT and to Universal Dependencies.
