Dialectal Arabic Tools

Dialectal Arabic Tools comprises the different modules developed in Qatar Computing Research Institute (QCRI) developed by the ALT team to handle Dialectal Arabic Segmentation, POS tagging, Diacritization and more

The segmentation module of Dialectal Arabic Tools

Dialectal Arabic Tools is compatible with: Python 2.7-3.5 or later.

Prerequisites

Before you can use the dialectal Arabic tools you need to install a special version of keras that comprises a CRF layer. Use the following pash command to install it.

It is better to do installations within a virtual environment. The following web page shows how to create a virtual environment in a straightforward steps.

pip install git+git://github.com/phipleg/keras@crf

Installation

You can install Dialectal Arabic Tools by either,

  • using pip (recommended)
  • cloning "this" repo and and use setup.py

Installing Dialectal Arabic Tools via pip

Use the following pash command to install the package from the python index,

pip install dialectal_arabic_tools

Installing Dialectal Arabic Tools from github

Clone the repo from the github website using the following command:

git clone https://github.com/qcri/dialectal_arabic_tools.git

Or download the compressed file of the project, extract it, change to the directory and run the following to install the Dialectal Arabic Tools using the following command:

 python setup.py install

Getting started

Dialectal Arabic Tools package is pretty easy to use. The following code snippets uses the dialectal segmention module to module a string of Arabic script encoded in UTF-8,

>>> from dialectal_arabic_tools.segmentation import segmenter
>>> segmenter.segment_text(u"عنا تنتين بندورة جبلية وخمسة عروقة نعنع بيعملو سلطة .. شلوني معك؟")
'عنا تنتين بندور+ة جبلي+ة و+خمس+ة عروق+ة نعنع ب+يعمل+و سلط+ة شلون+ي مع+ك ؟'

Furthermore, you could use the segmentation module to segment a text file of Arabic script encoded in UTF-8. Just use segment_file insted of segment_text. The segment_file function requires two two positional parameters, namely the file to be segmented and a file name to generate the output in.

>>> from dialectal_arabic_tools.segmentation import segmenter
>>> segmenter.segment_file(r'/path/to/text/file/you/need/to/segment.txt', r'output/file/path.txt')
