# Arabic Dialect Corpus

A comprehensive collection of Arabic dialectal text, standardized for Natural Language Processing (NLP) model training, evaluation, and linguistic analysis. This corpus has been meticulously processed to ensure high-quality tokenization and consistent metadata.

## Dataset Statistics

| Metric | Value |
| :--- | :--- |
| **Total Records** | 127,180 |
| **Total Tokens** | 5,802,324 |
| **Average Tokens per Record** | 45.62 |
| **Dialect Categories** | 5 |

## Changelog

### Version 1.0 (January 2026)

This release establishes the baseline for the corpus with strict quality controls:

- **Token Count**: Validated 5.8M+ tokens using `cl100k_base` (GPT-4 standard).
- **Data Density**: Optimized average record length to ~45 tokens for efficient training.
- **Dialect Coverage**: Confirmed distribution across 5 distinct dialect categories.
- **Quality Assurance**: Zero empty records and standardized metadata schema.

## Dataset Structure

Each record in the dataset contains the following fields:

- `text` (string): The raw Arabic text content.
- `topic` (string): The semantic category or topic of the text.
- `utterance_type` (string): Classification of the utterance (e.g., statement, question).
- `dialect` (string): The regional dialect name: `Masri` (Egyptian), `Khaleeji` (Gulf), `Levantine`, `Maghrebi` (North African), or `Iraqi`.
- `tokens` (int): The precise token count calculated using `cl100k_base` encoding.

## Usage

### Loading the Dataset

The dataset is hosted on the Hugging Face Hub and can be loaded directly using the `datasets` library.

```python
from datasets import load_dataset

# Load the complete dataset
dataset = load_dataset("dataflare/arabic-dialect-corpus")
```

## Detailed Methodology

### Collection and Processing
The data was aggregated from diverse sources including transcribed media and public archives. The processing pipeline involved:
1.  **Normalization**: Text normalization to remove noise while preserving dialectal features.
2.  **Segmentation**: Splitting long passages into training-ready chunks.
3.  **Token Counting**: Rigorous token counting using `tiktoken` to assist in curriculum training and length bucketing.
