The CINTIL-UDep treebank contains 37780 sentences and 473929 tokens.
The file cintil-udep.conllu in CONLL-U format, which is a TSV format (tab-separated values) with 10 columns:
- 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).
- FORM: Word form or punctuation symbol.
- LEMMA: Lemma of word form.
- UPOS: Universal part-of-speech tag.
- XPOS: Language-specific part-of-speech tag.
- FEATS: List of morphological features from the universal feature inventory or from a defined language-specific extension; underscore if not available.
- HEAD: Head of the current word, which is either a value of ID or zero (0).
- DEPREL: Universal dependency relation to the HEAD (root iff HEAD = 0) or a defined language-specific subtype of one.
- DEPS: Enhanced dependency graph in the form of a list of head-deprel pairs.
- MISC: Any other annotation.
Sentences are separated with empty lines. Note that both the POS and dependencies in this file are manually validated. The LX-UDParser was trained on a derivative of this file, where the POS annotations were made by the LX-UTagger, instead.
See https://universaldependencies.org/format.html#conll-u-format for more details on the CONLL-U format.
Lines starting with an hash (#) are comments.
The tokenization conforms to the CINTIL annotation guidelines.
