Piraye: NLP Utilities

Piraye is a Python library designed to facilitate text normalization for Persian, Arabic, and English languages.

Requirements

• Python 3.11+
• nltk 3.4.5+

Installation

You can install the latest version of Piraye via pip:

pip install piraye

Usage

To use Piraye, create an instance of the Normalizer class with NormalizerBuilder and then call the normalize function. You can configure the normalization process using various settings available. Below are two examples demonstrating different approaches:

• Using builder pattern:

from piraye import NormalizerBuilder

text = "این یک متن تسة اسﺘ       , 24/12/1400 "
normalizer = NormalizerBuilder().alphabet_fa().digit_fa().punctuation_fa().tokenizing().remove_extra_spaces().build()
normalizer.normalize(text)  # "این یک متن تست است ، ۲۴/۱۲/۱۴۰۰"

• Using constructor:

from piraye import NormalizerBuilder
from piraye.tasks.normalizer.normalizer_builder import Config

text = "این یک متن تسة اسﺘ       , 24/12/1400 "
normalizer = NormalizerBuilder([Config.PUNCTUATION_FA, Config.ALPHABET_FA, Config.DIGIT_FA], remove_extra_spaces=True,
                               tokenization=True).build()
normalizer.normalize(text)  # "این یک متن تست است ، ۲۴/۱۲/۱۴۰۰"
