{"default": {"description": "\nMac-Morpho is a corpus of Brazilian Portuguese texts annotated with part-of-speech tags.\nIts first version was released in 2003 [1], and since then, two revisions have been made in order\nto improve the quality of the resource [2, 3].\nThe corpus is available for download split into train, development and test sections.\nThese are 76%, 4% and 20% of the corpus total, respectively (the reason for the unusual numbers\nis that the corpus was first split into 80%/20% train/test, and then 5% of the train section was\nset aside for development). This split was used in [3], and new POS tagging research with Mac-Morpho\nis encouraged to follow it in order to make consistent comparisons possible.\n\n\n[1] Alu\u00edsio, S., Pelizzoni, J., Marchi, A.R., de Oliveira, L., Manenti, R., Marquiaf\u00e1vel, V. 2003.\nAn account of the challenge of tagging a reference corpus for brazilian portuguese.\nIn: Proceedings of the 6th International Conference on Computational Processing of the Portuguese Language.
