Definition of POS tag and Dependency label sets are used within Parsey McParseface?

Question

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?

Answer 1

After a bit more searching, it looks like the Stanford dependency grammar detailed here and POS tags detailed here.
