Reflexive pronouns in Spanish Universal Dependencies

Jasper Degraeuwe, Patrick Goethals


In this paper, we argue that in current Universal Dependencies treebanks, the annotation of Spanish reflexives is an unsolved problem, which clearly affects the accuracy and consistency of current parsers. We evaluate different proposals for fine-tuning the various categories, and discuss remaining open issues. We believe that the solution for these issues could lie in a multi-layered way of annotating the characteristics, combining annotation of the dependency relation and of the so-called token features, rather than in expanding the number of categories on one layer. We apply this proposal to the v2.5 Spanish UD AnCora treebank and provide a categorized conversion table that can be run with a Python script.
