opus-fast-mosestokenizer 0.0.8.2

c++ mosestokenizer

opus-fast-mosestokenizer is a fork of fast-mosestokenizer created to ensure compability of the package with current Python environments.

fast-mosestokenizer is a C++ implementation of the moses tokenizer which is a favourite among the folks in NLP research.

The reason for using this package over the original perl implementation is for the purpose of portability. With the C++ source code, you can use this library basically in every language.

The C++ script was adapted from the mosesdecoder repository contrib/c++tokenizer.

Python users using linux and osx>=10.15 can install directly from PyPI.

pip install fast-mosestokenizer

See ./INSTALL.md for more information.

Usage (Command-line tool)

# Piping is the standard way to configure input and output stream.
# mosestokenizer would apply tokenization to each line of the input stream.
mosestokenizer en < infile > outfile

# For a full list of options, refer to the help message.
mosestokenizer -h

Usage (Python)

# Usage patterns are mostly the same as sacremoses.
>>> from mosestokenizer import MosesTokenizer

>>> tokenizer = MosesTokenizer('en')
>>> tokenizer.tokenize("""
The English name of Singapore is an anglicisation of the native Malay name for
the country, Singapura, which was in turn derived from the Sanskrit word for
lion city (romanised: Siṃhapura; Brahmi: 𑀲𑀺𑀁𑀳𑀧𑀼𑀭; literally "lion city"; siṃha
means "lion", pura means "city" or "fortress").[8]
