Robust Tigrinya Byte Pair Encoding tokenizer

Tigriyna_BPE_Tokenizer

A Byte Pair Encoding (BPE) tokenizer for the Tigrinya language, designed for low-resource NLP research and machine learning pipelines.

Tigrinya is a low-resource Semitic language, and most existing tokenizers are optimized for high-resource languages. This project aims to reduce token fragmentation, lower out-of-vocabulary (OOV) rates, and better capture Tigrinya morphology.

Features

• BPE-based subword tokenization for Tigrinya
• Optimized for low-resource settings
• Reduced OOV rate and token fragmentation
• Easy integration into NLP pipelines
• Reproducible tokenizer training and evaluation

---

Motivation

Tokenization plays a critical role in NLP system performance. Generic tokenizers often perform poorly on Tigrinya due to:

• Rich morphology
• Limited training data
• Underrepresentation in multilingual models

This project addresses these challenges by providing a tokenizer tailored specifically to the Tigrinya language.
