Stanford Parser and NLTK

Question

Is it possible to use Stanford Parser in NLTK? (I am not talking about Stanford POS.)

Answer 1

I am using nltk version 3.2.4. And following code worked for me.

from nltk.internals import find_jars_within_path
from nltk.tag import StanfordPOSTagger
from nltk import word_tokenize

# Alternatively to setting the CLASSPATH add the jar and model via their 
path:
jar = '/home/ubuntu/stanford-postagger-full-2017-06-09/stanford-postagger.jar'
model = '/home/ubuntu/stanford-postagger-full-2017-06-09/models/english-left3words-distsim.tagger'

pos_tagger = StanfordPOSTagger(model, jar)

# Add other jars from Stanford directory
stanford_dir = pos_tagger._stanford_jar.rpartition('/')[0]
stanford_jars = find_jars_within_path(stanford_dir)
pos_tagger._stanford_jar = ':'.join(stanford_jars)

text = pos_tagger.tag(word_tokenize("Open app and play movie"))
print(text)

Output:

[('Open', 'VB'), ('app', 'NN'), ('and', 'CC'), ('play', 'VB'), ('movie', 'NN')]
