ParCor - A Parallel Pronoun-Coreference Corpus

ParCor 1.0 is a parallel corpus of texts in which pronoun coreference -- reduced coreference in which pronouns are used as referring expressions -- has been annotated. It consists of a collection of parallel English-German documents from two different text genres: TED Talks (transcribed planned speech), and EU Bookshop publications (written text). All documents in the corpus have been manually annotated with respect to the type and location of each pronoun and, where relevant, its antecedent.

The corpus is intended to be used both as a resource from which to learn systematic differences in pronoun use between languages and ultimately for developing and testing informed Statistical Machine Translation systems aimed at addressing the problem of pronoun coreference in translation.

If you make use of the ParCor corpus in your work, please cite the following article:

We would like to thank our annotators, Susanne Tauber, Petra Strom, Samuel Gibbon, David Lawrence and Aaron Smith for their many hours of painstaking work and Yannick Versley for making his German pre-processing pipeline available to us. The work was suppored by the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement 287658 (EU BRIDGE) and by the Swedish Research Council (Vetenskapsrådet) through the project on Discourse-Oriented Machine Translation (2012- 916).
