Floresta Sintá(c)tica: A treebank for Portuguese

Abstract

This paper reviews the first year of the creation of a publicly available treebank for Portuguese, Floresta Sintá(c)tica, a collaboration project between the VISL and the Computational Processing of Portuguese projects. After briefly describing the main goals and the organization of the project, the creation of the annotated objects is presented in detail: preparing the text to be annotated, applying the Constraint Grammar based PALAVRAS parser, revising its output manually in a two-stage process, and carefully documenting the linguistic options. Some examples of the kind of interesting problems dealt with are presented, and the paper ends with a brief description of the tools developed, the project results so fa1.r, and a mention to a preliminary inter-annotator test and what was learned from it.
