nnsplit 0.2.1

Fast, robust sentence splitting with bindings for Python, Rust and Javascript.

NNSplit Python Bindings

Fast, robust sentence splitting with bindings for Python, Rust and Javascript and pretrained models for English and German.

Installation

NNSplit has PyTorch as the only dependency.

Install it with pip: pip install nnsplit

Usage

>>> from nnsplit import NNSplit
>>> splitter = NNSplit("en")
# NNSplit does not depend on proper punctuation and casing to split sentences
>>> splitter.split(["This is a test This is another test."])
[[[Token(text='This', whitespace=' '),
   Token(text='is', whitespace=' '),
   Token(text='a', whitespace=' '),
   Token(text='test', whitespace=' ')],
  [Token(text='This', whitespace=' '),
   Token(text='is', whitespace=' '),
   Token(text='another', whitespace=' '),
   Token(text='test', whitespace=''),
   Token(text='.', whitespace='')]]]

Models for German (NNSplit("de")) and English (NNSplit("en")) come prepackaged with NNSplit. Alternatively, you can also load your own model:

import torch
model = torch.jit.load("/path/to/your/model.pt") # a regular nn.Module works too

splitter = NNSplit(model)

See train.ipynb for the code used to train the pretrained models.

Development

NNSplit uses Poetry for dependency management. I made a small Makefile to automate some steps. Take a look at the Makefile and run make install, make build, make test to install, build and test the library, respectively.
