Dataset Description

• Website: https://github.com/UniversalDependencies/UD_Spanish-AnCora
• Point of Contact: Daniel Zeman

Dataset Summary

This dataset is composed of the annotations from the AnCora corpus, projected on the Universal Dependencies treebank. We use the POS annotations of this corpus as part of the EvalEs Spanish language benchmark.

Supported Tasks and Leaderboards

POS tagging

Languages

The dataset is in Spanish (es-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.

Initial Data Collection and Normalization

The original annotation was done in a constituency framework as a part of the AnCora project at the University of Barcelona. It was converted to dependencies by the Universal Dependencies team and used in the CoNLL 2009 shared task. The CoNLL 2009 version was later converted to HamleDT and to Universal Dependencies.
