This paper introduces the journalistic portion of the Porttinari treebank, which aims to be a multigenre NLP resource for Brazilian Portuguese. We report the construction of the treebank, in particular, the human-revised portion with 8,418 sentences, whose annotation process lasted almost three years and involved more than a dozen trained annotators. The full treebank offers to the Portuguese-speaking NLP community nearly 4 million sentences annotated according to the Universal Dependencies framework.
