Installation

• To install this python wrapper for VnCoreNLP, users have to run the following command:

  $ pip install py_vncorenlp

Example usage

import py_vncorenlp

# Automatically download the VnCoreNLP model from the original resitory
py_vncorenlp.download_model()

# Load the pretrained VnCoreNLP model
model = py_vncorenlp.VnCoreNLP(annotators=["wseg", "pos", "ner", "parse"])

# Annotate a corpus where each line represents a raw sentence
model.annotate_file(input_file="input.txt", output_file="output.txt")

# Annotate a raw sentence
model.print_out(model.annotate_sentence("Ông Nguyễn Khắc Chúc  đang làm việc tại Đại học Quốc gia Hà Nội.")

By default, the output for each input sentence is formatted with 6 columns representing word index, word form, POS tag, NER label, head index of the current word and its dependency relation type:
