Stanford NLP pos tag PRN

I am using Stanford's CoreNLP pipeline. I am getting following TreeAnnotation:

(ROOT (S (NP (PRP I)) (VP (VP (VBP love) (NP (NN hepling))) (PRN (CC and) (ADJP (JJ willing) (S (VP (TO to) (VP (VB help)))))))))

Note: the sentence is grammatically incorrect, but this is intensional.

What is "PRN" tag in TreeAnnotation?

I did not find such tag in Penn tags nor in Stanford dependency tags.

Solution

  • The labels can be over individual words (part of speech tags) or phrases (phrasal categories). PRN is a phrasal category for parenthetical phrases.

    See What do the abbreviations in POS tagging etc mean? which will point you to a full list of phrasal and part-of-speech tags.
