Dataset Details

PortuLex is composed by: LeNER-Br, Rhetorical Role Identification (RRI), FGV-STF, UlyssesNER-Br.

  • LeNER-Br: the first Named Entity Recognition (NER) corpus for the legal domain in Brazilian Portuguese from higher and state-level courts.
  • RRI: rhetorical annotations from judicial sentences from the Court of Justice of Mato Grosso do Sul (Brazil).
  • FGV-STF: decisions from the Supreme Federal Court for entity extraction.
  • UlyssesNER-Br: NER corpus of bills and legislative queries from the Chamber of Deputies of Brazil.
