Constituency Parse Tree output

Constituency Parse Tree output

mercurial-moon opened this issue a year ago · 3 comments

I see that the output for constituency parse output in the text, xml or json files is given as a long string like so

Constituency parse: 
(ROOT
  (S
    (NP (NNP Stanford) (NNP University))
    (VP (VBZ is)
      (VP (VBN located)
        (PP (IN in)
          (NP (NNP California)))))
    (. .)))

This would be needed to be parsed to get it into a structured tree.
Is there a parser available for this by default in CoreNLP, or is there a more direct output (in tree format) available by querying the api ?

Please explain what you mean by "structured tree". Do you want a list of Tree objects in Java? You can get that using the DiskTreebank class https://nlp.stanford.edu/nlp/javadoc/javanlp-4.5.1/index.html?edu/stanford/nlp/trees/DiskTreebank.html

Hi,
Yes I was looking to getting the constituency parse data as a tree of java objects.
I found some api samples here

Tree constituencyParse = sentence.constituencyParse();

Is this ok instead of the DiskTreebank

Yes, I had thought your trees were already in a file and you needed them back, but there are several ways to access them as part of the API
