Definition of POS tags and Dependency sticker sets used in Parsey McParseface?

Question

The POS icons and Depedency labels displayed by Parsey McParseface are listed in the tag-set and label-set files here, respectively.

The Syntaxnet file indicates that the model was trained on Penn Treebank, OntoNotes, and Treebanks English websites.

Is there a detailed description of the corresponding POS tags and Dependency tags used in these tree structures, similar to those defined by the Universal Dependency project?

Answer 1

After a bit more searching, it looks like Stanford's dependency grammar is described in detail here and POS tags in detail here .
