For our experiments, we use the AnCora-UPF SSyntS and DSyntS treebanks of Spanish (Mille et al., 2013) in CoNLL format, adjusted for our needs.
we removed from the 79-tag SSyntS treebank the semantically and information structure influenced relation tags to obtain an annotation granularity closer to the ones used for previous parsing experiments (55 relation tags, see (Mille et al., 2012)).
