A Python wrapper for VnCoreNLP using a bidirectional communication channel.
You can install this package from PyPI using pip:
$ [sudo] pip install vncorenlp
For Windows users, please ensure that you run the Command Prompt with admin privileges.
A simple example of how to use vncorenlp:
#!/usr/bin/python
# -*- coding: utf-8 -*-
import logging
from vncorenlp import VnCoreNLP
def simple_usage():
# Uncomment this line for debugging
# logging.basicConfig(level=logging.DEBUG)
vncorenlp_file = r'.../VnCoreNLP-1.0.1/VnCoreNLP-1.0.1.jar'
sentences = 'VTV đồng ý chia sẻ bản quyền World Cup 2018 cho HTV để khai thác. ' \
'Nhưng cả hai nhà đài đều phải chờ sự đồng ý của FIFA mới thực hiện được điều này.'
# Use "with ... as" to close the server automatically
with VnCoreNLP(vncorenlp_file) as vncorenlp:
print('Tokenizing:', vncorenlp.tokenize(sentences))
print('POS Tagging:', vncorenlp.pos_tag(sentences))
print('Named-Entity Recognizing:', vncorenlp.ner(sentences))
print('Dependency Parsing:', vncorenlp.dep_parse(sentences))
print('Annotating:', vncorenlp.annotate(sentences))
print('Language:', vncorenlp.detect_language(sentences))
# In this way, you have to close the server manually by calling close function

I highly recommend you to use this approach to save your time when you are debugging your code.
First, you need to start the VnCoreNLPServer using this command:
$ vncorenlp -Xmx2g <VnCoreNLP File> -p 9000 -a "wseg,pos,ner,parse"
The parameter -Xmx2g means that the VM can allocate a maximum of 2 GB for the Heap Space.
And then connect to the server using this code:
# Use the existing server
with VnCoreNLP(address='http://127.0.0.1', port=9000) as vncorenlp:
...There are 3 ways to enable debugging:
#!/usr/bin/python
# -*- coding: utf-8 -*-
import logging
import sys
from vncorenlp import VnCoreNLP
# 1. Use the global logger
# logging.basicConfig(level=logging.DEBUG)
def simple_usage():
vncorenlp_file = r'.../VnCoreNLP-1.0.1/VnCoreNLP-1.0.1.jar'
sentences = 'VTV đồng ý chia sẻ bản quyền World Cup 2018 cho HTV để khai thác. ' \
'Nhưng cả hai nhà đài đều phải chờ sự đồng ý của FIFA mới thực hiện được điều này.'
# Use "with ... as" to close the server automatically
vncorenlp = VnCoreNLP(vncorenlp_file)
# 2. Set up the local logger here
logger = vncorenlp.logger
logger.setLevel(logging.DEBUG)
# Add stdout
ch = logging.StreamHandler(sys.stdout)
ch.setLevel(logging.DEBUG)
# Add formatter
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
ch.setFormatter(formatter)
logger.addHandler(ch)

print('Tokenizing:', vncorenlp.tokenize(sentences))
print('POS Tagging:', vncorenlp.pos_tag(sentences))
print('Named-Entity Recognizing:', vncorenlp.ner(sentences))
print('Dependency Parsing:', vncorenlp.dep_parse(sentences))
print('Annotating:', vncorenlp.annotate(sentences))
