How to get all noun phrases in Spacy

Question

I am new to Spacy and I would like to extract \"all\" the noun phrases from a sentence. I\'m wondering how I can do it. I have the following code:

i         


        

Answer 1

For every noun chunk you can also get the subtree beneath it. Spacy provides two ways to access that:left_edge and right edge attributes and the subtree attribute, which returns a Token iterator rather than a span. Combining noun_chunks and their subtree lead to some duplication which can be removed later.

Here is an example using the left_edge and right edge attributes

{np.text
  for nc in doc.noun_chunks
  for np in [
    nc, 
    doc[
      nc.root.left_edge.i
      :nc.root.right_edge.i+1]]}                                                                                                                                                                                                                                                                                                                                                                                                                                                 

==>

{'We',
 'the edges',
 'the edges of the images',
 'the geometry',
 'the geometry of the edges of the images',
 'the images'}
