Aranizer: A Custom Tokenizer for Enhanced Arabic Language Processing

AraNizer

Description

AraNizer is a sophisticated toolkit of custom tokenizers tailored for Arabic language processing. Integrating advanced methodologies such as SentencePiece and Byte Pair Encoding (BPE), these tokenizers are specifically designed for seamless integration with the transformers and sentence_transformers libraries. The AraNizer suite offers a range of tokenizers, each optimized for distinct NLP tasks and accommodating varying vocabulary sizes to cater to a multitude of linguistic applications.

Key Features

• Versatile Tokenization: Supports multiple tokenization strategies (BPE, SentencePiece) for varied NLP tasks.
• Broad Vocabulary Range: Customizable tokenizers with vocabulary sizes ranging from 32k to 86k.
• Seamless Integration: Compatible with popular libraries like transformers and sentence_transformers.
• Optimized for Arabic: Specifically engineered for the intricacies of the Arabic language.

Installation

Install AraNizer effortlessly with pip:

pip install aranizer

Usage

Importing Tokenizers

Import your desired tokenizer from AraNizer. Available tokenizers include:

• BEP variants: aranizer_bpe50k, aranizer_bpe64k,
• SentencePiece variants: aranizer_bpe86k, aranizer_sp32k, aranizer_sp50k, aranizer_sp64k, aranizer_sp86k.

from aranizer import aranizer_sp32k  # Replace with your chosen tokenizer

#Load your tokenizer:
tokenizer = aranizer_sp32k.get_tokenizer()

Tokenizing Text

Tokenize Arabic text using the selected tokenizer:

text = "مثال على النص العربي"  # Example Arabic text
tokens = tokenizer.tokenize(text)
print(tokens)

Encoding and Decoding

Encode text into token ids and decode back to text.

Encoding: To encode text, use the encode method.

text = "مثال على النص العربي"  # Example Arabic text
encoded_output = tokenizer.encode(text, add_special_tokens=True)
print(encoded_output)

Decoding: To convert token ids back to text, use the decode method:

decoded_text = tokenizer.decode(encoded_output)
print(decoded_text)
