Online documentation explaining tags output by Stanford NLP parser?

Question

is there any online documentation explaining tags output by Stanford NLP parser?

I'm quite new to NLP and and to me it seems that the tags like NN, VBZ, .. and relationships like poss, nsubj ... seem to follow a kind of standard since I've seen this output on other parsers.

thanks a lot!

For grammatical dependencies (nsubj, poss...), you can read the official manual: http://nlp.stanford.edu/software/dependencies_manual.pdf

Tags like NN, VBZ... are part-of-speech tags. You can find info about them here: https://www.ling.upenn.edu/courses/Fall_2003/ling001/penn_treebank_pos.html, or by googling "part-of-speech tags penn treebank"
