A Portuguese-Spanish Corpus Annotated for Subject Realization and Referentiality
Luz Rello, Iria Gayo · 2012
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.
