Summary of the paper

Title A Portuguese-Spanish Corpus Annotated for Subject Realization and Referentiality
Authors Luz Rello and Iria Gayo
Abstract This paper presents a comparable corpus of Portuguese and Spanish consisting of legal and health texts. We describe the annotation of zero subject, impersonal constructions and explicit subjects in the corpus. We annotated 12,492 examples using a scheme that distinguishes between different linguistic levels (phonology, syntax, semantics, etc.) and present a taxonomy of instances on which annotators disagree. The high level of inter-annotator agreement (83%-95%) and the performance of learning algorithms trained on the corpus show that our corpus is a reliable and useful resource.
Topics Corpus (creation, annotation, etc.), Anaphora, Coreference, Validation of LRs
