Noun chunk info from token

Hello spaCy team!

It appears that there isn’t an option to determine whether any single token is part of a noun chunk (as determined from doc.noun_chunks), in the same way as token.ent_iob.

The main problem that I am trying to solve is merging noun_chunks in specific sentences.

Is this a feature that could be added? Or is there another solution?

Maybe we should have a span2doc function? I think this might take some pressure off the span objects.

Trying to tie noun_chunks to specific sentences is a feature I’m trying to build as well. I altered your code @owlas for those trying to run it live on a document.

noun_words = set(w.i for nc in doc.noun_chunks for w in nc)
for s in doc.sents:
    noun_from_chunks_in_sentence = [w for w in s if w.i in noun_words]
    print s.text
    print noun_from_chunks_in_sentence

I’m assuming this just needs to be changed to check the left and right most child of the noun chunk is inside the sentence left/right most child.

for s in doc.sents:
    print s.text
    for nc in doc.noun_chunks:
        if nc.start >= s.start and nc.end <= s.end:
            print "INSIDE: " + nc.text
        else:
            print "OUT: " + nc.text
        print s.start, s.end
        print nc.start, nc.end
        print ""
