Description
UD Cuicatec-MesoTree consists of sentences in Tepeuxila Cuicatec annotated as part of the NSF-funded project “Syntactically-annotated corpora for endangered languages in areal contact” (MesoTree).
Cuicatec (dibaku, dbaku, dubaku) is an Oto-Manguean language of the Mixtecan branch, spoken in the southern Cañada region of Oaxaca, Mexico. The treebank is of Tepeuxila Cuicatec (dbaku), spoken in the communities around San Juan Tepeuxila.
The pre-existing dictionary example sentences initially contemplated for annotation are in a variety of Tepeuxila Cuicatec different from that of the collaborators, so the treebank was instead created by:
- translating the elicitation sentences from the Archivo de lenguas indígenas de México (ALIMG) (sentence IDs beginning with
alimg); - asking our collaborators to produce word lists and coming up with a sentence for each (sentence IDs beginning with
ejemplos).
The sentences are written following the collaborators’ own orthographic norms for their language variety.
The original text is given in text[orig], a normalised version in text (affecting apostrophes and capitalisation), and a Spanish
translation in text[spa]. Non-standard spellings are marked Typo=Yes, usually with the standard
form in the MISC attribute Normal. The MISC column also contains morpheme glosses (Gloss) and Spanish word
translations (Trad) for some of the words.
The sentences were annotated in a web interface combining UD Annotatrix and Arborator-Grew, with final annotations decided by group consensus. Lemmas and morphological features are not yet annotated for the whole corpus.
