The Coreference Annotation of the CSTNews Corpus

Francielle Vargas, Thiago A. S. Pardo

Abstract:

We report in this paper the coreference annotation process of the CSTNews corpus as part of a collective task of the IberEval 2017
conference. The annotated corpus is composed of 140 news texts written in the Brazilian Portuguese language and counts with several annotation layers, including annotations in the morphosyntax/syntax, semantics, and discourse levels. The annotation, focused on nominal references, was conducted in a semi-automatic way by five teams, achieving satisfactory annotation agreement results.
