Semantic Role Labeling - Brazilian Portuguese

Last modified by Leonardo Zilio on 2015-08-27

This project aims at the creation of lexical resources annotated with semantic roles for Portuguese.

Up til now, we annotated more than six thousand sentences in two corpora. One of the corpora contains Cardiology papers from three Brazilian journals, while the other is composed by newspaper articles from the Diário Gaúcho newspaper. The annotated sentences are organized according to verb and subcategorization frames. There are also verbs and sentences without semantic role annotation, since the annotation was made through sampling.

More information about the developments of the projects can be found on the following publications:

The XML and SQL files are available for download in the links below. And both give access to all the sentences of the corpora, organized alphabetically by verb. Some of these sentences are already annotated with semantic roles, but the majority of them has only syntactic information, as explained above.

The XML files from both corpora can be downloaded using the following links:

The SQL files from both corpora are here.
