NPChunks is a training corpus containing approximately 1,000 sentences, with a total of 24,243 tokens, selected randomly from the written part of the CINTIL corpus. For more information on the CINTIL corpus, see ELRA-W0050, ISLRN: 176-775-844-396-0. The corpus is PoS-annotated at token level, including punctuation. Noun Phrases were recognized and annotated with specific tags. It was automatically PoS-tagged with MBT tagger (http://ilk.uvt.nl/mbt/), and lemmatized with MBLEM (http://ilk.uvt.nl/mbma/), following the annotation scheme of the Corpus of Reference of Contemporary Portuguese. YamCha software (http://chasen.org/~taku/software/yamcha/) was used to recognize chunks that consist of Noun Phrases and to identify the elements appearing at the beginning, in the middle and at the end of a noun phrase.
