The POS tags and Depedency labels output by Parsey McParseface are given in the tag-set and label-set files here respectively.
The Syntaxnet readme outlines that the model was trained on the Penn Treebank, OntoNotes and the English Web Treebanks.
Is there a detailed description of the corresponding POS tags and Dependency labels used in these treebanks similar to that given by the Universal Dependency project?
