Natural Language Toolkit for Indic Languages (iNLTK)

Alt Text

Installation

pip install http://download.pytorch.org/whl/cpu/torch-1.0.0-cp36-cp36m-linux_x86_64.whl
pip install inltk

iNLTK runs on CPU and NOT on GPU, as is the desired behaviour for most of the Deep Learning models in production.

The first command above will install pytorch-cpu, which, as the name suggests, does not have cuda support.

Note: inltk is currently supported only on Linux with Python >= 3.6

Supported languages

Language Code
Hindi hi
Punjabi pa
Sanskrit sa
Gujarati gu
Kannada kn
Malyalam ml
Nepali ne
Odia or
Marathi mr
Bengali bn

Usage

Setup the language

from inltk.inltk import setup

setup('<code-of-language>') // if you wanted to use hindi, then setup('hi')

Note: You need to run setup('<code-of-language>') when you use a language for the FIRST TIME ONLY. This will download all the necessary models required to do inference for that language.

Tokenize

from inltk.inltk import tokenize

tokenize(text ,'<code-of-language>') // where text is string in <code-of-language>

Predict Next 'n' words

from inltk.inltk import predict_next_words

predict_next_words(text , n, '<code-of-language>') 

// text --> string in <code-of-language>
// n --> number of words you want to predict (integer)

Note: You can also pass a fourth parameter, randomness, to predict_next_words. It has a default value of 0.8

Identify language

from inltk.inltk import identify_language

identify_language(text)

// text --> string in one of the supported languages

Example:

>> identify_language('न्यायदर्शनम् भारतीयदर्शनेषु अन्यतमम्। वैदिकदर्शनेषु ')
'sanskrit'
