## Byte Level (BPE) Tokenizer for Arabic
|
15 |
+
|
16 |
+
Byte Level Tokenizer for Arabic, a robust tokenizer designed to handle Arabic text with precision and efficiency.
|
17 |
+
This tokenizer utilizes a `Byte-Pair Encoding (BPE)` approach to create a vocabulary of `32,000` tokens, catering specifically to the intricacies of the Arabic language.
|
18 |
+
|
19 |
+
### Goal
|
20 |
+
|
21 |
+
This tokenizer was created as part of the development of an Arabic BART transformer model for summarization from scratch using `PyTorch`.
|
22 |
+
In adherence to the configurations outlined in the official [BART](https://arxiv.org/abs/1910.13461) paper, which specifies the use of BPE tokenization, I sought a BPE tokenizer specifically tailored for Arabic.
|
23 |
+
While there are Arabic-only tokenizers and multilingual BPE tokenizers, a dedicated Arabic BPE tokenizer was not available. This gap inspired the creation of a `BPE` tokenizer focused solely on Arabic, ensuring alignment with BART's recommended configurations and enhancing the effectiveness of Arabic NLP tasks.
|
24 |
+
|
25 |
+
### Checkpoint Information
|
26 |
+
|
27 |
+
- **Name**: `IsmaelMousa/arabic-bpe-tokenizer`
|
28 |
+
- **Vocabulary Size**: `32,000`
|
29 |
+
|
30 |
+
### Overview
|
31 |
+
|
32 |
+
The Byte Level Tokenizer is optimized to manage Arabic text, which often includes a range of diacritics, different forms of the same word, and various prefixes and suffixes. This tokenizer addresses these challenges by breaking down text into byte-level tokens, ensuring that it can effectively process and understand the nuances of the Arabic language.
|
33 |
+
|
34 |
+
### Features
|
35 |
+
|
36 |
+
- **Byte-Pair Encoding (BPE)**: Efficiently manages a large vocabulary size while maintaining accuracy.
|
37 |
+
- **Comprehensive Coverage**: Handles Arabic script, including diacritics and various word forms.
|
38 |
+
- **Flexible Integration**: Easily integrates with the `tokenizers` library for seamless tokenization.
|
39 |
+
|
40 |
+
### Installation
|
41 |
+
|
42 |
+
To use this tokenizer, you need to install the `tokenizers` library. If you haven’t installed it yet, you can do so using pip:
|
43 |
+
|
44 |
+
```bash
|
45 |
+
pip install tokenizers
|
46 |
+
```
|
47 |
+
|
48 |
+
### Example Usage
|
49 |
+
Here is an example of how to use the Byte Level Tokenizer with the `tokenizers` library.
|
50 |
+
|
51 |
+
|
52 |
+
This example demonstrates tokenization of the Arabic sentence "لاشيء يعجبني, أريد أن أبكي":
|
53 |
+
|
54 |
+
```python
|
55 |
+
from tokenizers import Tokenizer
|
56 |
+
|
57 |
+
tokenizer = Tokenizer.from_pretrained("IsmaelMousa/arabic-bpe-tokenizer")
|
58 |
+
|
59 |
+
text = "لاشيء يعجبني, أريد أن أبكي"
|
60 |
+
|
61 |
+
encoded = tokenizer.encode(text)
|
62 |
+
decoded = tokenizer.decode(encoded.ids)
|
63 |
+
|
64 |
+
print("Encoded Tokens:", encoded.tokens)
|
65 |
+
print("Token IDs:", encoded.ids)
|
66 |
+
print("Decoded Text:", decoded)
|
67 |
+
|
68 |
+
```
|
69 |
+
|
70 |
+
output:
|
71 |
+
|
72 |
+
```bash
|
73 |
+
Encoded Tokens: ['<s>', 'ÙĦا', 'ĠØ´ÙĬØ¡', 'ĠÙĬع', 'جب', 'ÙĨÙĬ', ',', 'ĠأرÙĬد', 'ĠØ£ÙĨ', 'Ġأب', 'ÙĥÙĬ', '</s>']
|
74 |
+
|
75 |
+
Token IDs: [0, 419, 1773, 667, 2281, 489, 16, 7578, 331, 985, 1344, 2]
|
76 |
+
|
77 |
+
Decoded Text: لا شيء يعجبني, أريد أن أبكي
|
78 |
+
```
|
79 |
+
|
80 |
+
### Tokenizer Details
|
81 |
+
- **Byte-Level Tokenization**: This method ensures that every byte of input text is considered, making it suitable for languages with complex scripts.
|
82 |
+
- **Adaptability**: Can be fine-tuned or used as-is, depending on your specific needs and application scenarios.
