| ### 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. | |

| ### Personal and Sensitive Information | |
| No personal or sensitive information included. | |
| ## Considerations for Using the Data | |
| ### Social Impact of Dataset | |
