anltk 0.4.0

Arabic language processing toolkit

Arabic Natural Language Toolkit (ANLTK)

ANLTK is a set of Arabic natural language processing tools. developed with focus on performance.

ANLTK is a C++ library, with python bindings.

Installation

for python :

pip install pybind11
pip install anltk

Building

Note: Currently only tested on Linux
The Library depends on https://github.com/nemtrif/utfcpp.git, which is cloned automatically.
you also need a modern C++ Compiler, which supports C++17 also meson and ninja needs to be installed.
simply with pip

pip install meson
pip install ninja

git clone --recurse-submodules https://github.com/Abdullah-AlAttar/anltk.git \
    && cd anltk/anltk \
    && meson build --buildtype=release -Dbuild_tests=false \
    && cd build \
    && ninja \
    && cd ../../ \
    && python3 setup.py install

Usage Examples:

C++ API :

#include "anltk/anltk.hpp"
#include <iostream>
#include <string>

int main()
{

    std::string ar_text = "أبجد هوز حطي كلمن سعفص قرشت ثخذ ضظغ";

    std::cout << anltk::transliterate(ar_text, anltk::CharMapping::AR2BW) << '\n';
    // >bjd hwz HTy klmn sEfS qr$t vx* DZg

    std::string text = "فَ، حُلْوَةٌ مُهَنْدَمَةٌ تُدْهِشُ الإِنْسَانَ.";

    std::cout << anltk::remove_tashkeel(text) << '\n';
    // فراشة ملونة تطير في البستان، حلوة مهندمة تدهش الإنسان.

    // Third paramters is a stop_list, charactres in this list won't be removed
    std::cout << anltk::remove_non_alpha(text, " ") << '\n';
    // فراشة ملونة تطير في البستان حلوة مهندمة تدهش الإنسان
}

Python API

import anltk


ar = "أبجد هوز حطي كلمن سعفص قرشت ثخذ ضظغ"
bw = anltk.transliterate(ar, anltk.AR2BW)
print(bw)
# >bjd hwz HTy klmn sEfS qr$t vx* DZg

print(anltk.remove_tashkeel("فَرَاشَةٌ مُلَوَّنَةٌ تَطِيْرُ في البُسْتَانِ، حُلْوَةٌ مُهَنْدَمَةٌ تُدْهِشُ الإِنْسَانَ."))

# فراشة ملونة تطير في البستان، حلوة مهندمة تدهش الإنسان.
