afaanoromo-tokenizer 1.1.3

Tokenizer library for Afaan Oromo supporting Unigram, BPE, and WordPiece algorithms.

Afaan Oromo Tokenizer

Afaan_oromo_tokenizer is a linguistically informed and computationally efficient tokenizer for Afaan Oromo, one of the most widely spoken low-resource languages in Africa.

---

• While tokenizers exist for major languages (English, Chinese, etc.), Afan Oromo lacks robust open-source tokenization tools.
• Afaan_oromo_tokenizer bridges that gap, facilitating NLP research for afaan Oromo.

---

Features

• Included: BPE, Unigram, WordPiece
• Trained on 14 million tokens
• Total unique tokens in dataset: 420,000
• Vocabulary size for each tokenizer type: 55,000

---

Installation

pip install afaanoromo-tokenizer

Usage

from afaanoromo_tokenizer import ao_tokenizer

# Example text
text = "Afaanni Oromoo afaan saba guddaati!"

# --- BPE tokenizer ---
bpe_tokenizer = ao_tokenizer("bpe")
bpe_encoded = bpe_tokenizer.encode(text)

print("BPE tokens:", bpe_encoded.tokens)
print("BPE ids:", bpe_encoded.ids)

bpe_decoded = bpe_tokenizer.decode(bpe_encoded.ids)
print("BPE decoded:", bpe_decoded)

# --- Unigram tokenizer ---
unigram_tokenizer = ao_tokenizer("unigram")
unigram_encoded = unigram_tokenizer.encode(text)

print("Unigram tokens:", unigram_encoded.tokens)
print("Unigram ids:", unigram_encoded.ids)

unigram_decoded = unigram_tokenizer.decode(unigram_encoded.ids)
print("Unigram decoded:", unigram_decoded)

# --- WordPiece tokenizer ---
wordpiece_tokenizer = ao_tokenizer("wordpiece")
wordpiece_encoded = wordpiece_tokenizer.encode(text)

print("WordPiece tokens:", wordpiece_encoded.tokens)
print("WordPiece ids:", wordpiece_encoded.ids)

wordpiece_decoded = wordpiece_tokenizer.decode(wordpiece_encoded.ids)
print("WordPiece decoded:", wordpiece_decoded)
