Title
Corref-Pt:A Semi-Automatic Annotated Portuguese Coreference Corpus
Abstract
This paper describes the Portuguese coreference corpus Corref-PT, annotated semi-automatically using the coreference annotation tool CORP, and manually revised with the editing tool CorrefVisual. It includes a total of 182 texts, mostly news (corpus CSTNews, corpus LE-PAROLE, FAPESP magazine) but also articles from Wikipedia. The result is a corpus that includes a total of 3898 reference chains. We present the coreference annotation tool CORP, which was built on the basis of deterministic rules, and the editor CorrefVisual used for manual revision. We report on the annotation agreement and on the feedback provided by the annotators regarding the editor and the complexity of the task. Examples of technical and linguistic issues encountered during the annotation are given and the pros and cons of such approach for corpus construction are discussed. Our motivation was to use of a semi-automatic approach to increase the set of available resources for coreference resolution applications for Portuguese.
