Propbank-Br: a Brazilian Treebank annotated with semantic role labels
Magali Sanches Duran, Sandra Maria Aluísio · 2012
This paper reports the annotation of a Brazilian Portuguese Treebank with semantic role labels following Propbank guidelines.A different language and a different parser output impact the task and require some decisions on how to annotate the corpus.Therefore, a new annotation guide -called Propbank-Br -has been generated to deal with specific language phenomena and parser problems.In this phase of the project, the corpus was annotated by a unique linguist.The annotation task reported here is inserted in a larger projet for the Brazilian Portuguese language.This project aims to build Brazilian verbs frames files and a broader and distributed annotation of semantic role labels in Brazilian Portuguese, allowing inter-annotator agreement measures.The corpus, available in web, is already being used to build a semantic tagger for Portuguese language.
