# 🇪🇬🇸🇦 Arabic Dialect Corpus (Egyptian & Saudi)

## Dataset Description

This dataset contains **150K+ natural, informal Arabic text samples** scraped from high-engagement YouTube discussions. It specifically targets **Egyptian (EG)** and **Saudi (SA)** dialects, filling a critical gap in resources for training LLMs on colloquial Arabic (*Ammiya*) rather than just Modern Standard Arabic (MSA).

### Languages

* **Primary Dialects**:
- Egyptian Arabic (EG) - Cairene and regional Egyptian variants
- Saudi Arabic (SA) - Najdi and Hijazi Gulf variants
- General Arabic (AR) - Mixed or pan-dialectal colloquial Arabic
* **Script**: Arabic script with colloquial spelling conventions
* **Type**: Informal, conversational text

## Dataset Summary

Modern Arabic exists on a spectrum from formal Modern Standard Arabic (MSA) to highly localized dialects. While MSA dominates written content, colloquial dialects (*Ammiya*) dominate everyday communication, social media, and informal contexts. This dataset provides:

* **Authentic dialect data**: Real conversations from native speakers
* **Regional coverage**: Two major Arabic dialect groups (Egyptian and Gulf)
* **Simple labeling**: Clean 3-field schema (text, label, score)
* **Quality filtering**: Community-validated content via engagement metrics
* **Training-ready format**: JSONL optimized for streaming workflows

## Dataset Structure

### Data Format

Each entry contains:

```json
{
"text": "يا جدعان الفيديو ده تحفة بجد بس محتاج شوية تظبيط في الصوت",
"label": "EG",
"score": 45
}
```

### Data Fields

| Field | Type | Description |
|-------|------|-------------|
| `text` | string | Cleaned Arabic comment text (colloquial dialect) |
| `label` | string | Dialect label: "EG" (Egyptian), "SA" (Saudi), or "AR" (General Arabic) |
| `score` | int64 | Community engagement score (like count) |

## Dataset Statistics

### Overview

* **Total Entries**: ~150,000+
* **Source Platform**: YouTube
* **Content Type**: User comments and discussions
* **Dialect Coverage**: Egyptian and Saudi Arabian variants
* **Average Text Length**: 15-80 words per entry
* **Quality Range**: Filtered for minimum engagement and coherence

### Label Distribution

| Label | Description | Percentage |
|-------|-------------|------------|
| `EG` | Egyptian Arabic (Cairene and regional variants) | ~60% |
| `SA` | Saudi Arabic (Najdi, Hijazi variants) | ~35% |
| `AR` | General colloquial Arabic (mixed or unidentified) | ~5% |

### Content Distribution

The dataset draws from multiple video categories to ensure diverse vocabulary and contexts:

* **Talk Shows & Podcasts**: 35%
* **Technology Reviews**: 25%
* **Entertainment & Comedy**: 20%
* **Social Commentary**: 15%
* **Other**: 5%

## Dialect Information

### Label Classification

The `label` field indicates the dialect type:

* **EG**: Egyptian Arabic markers detected (e.g., إزيك, يعني, عايز, كده, بتاع)
* **SA**: Saudi/Gulf Arabic markers detected (e.g., وش, كيف, عندك, ياخي, حق)
* **AR**: Mixed or unclear dialectal markers, general colloquial Arabic

**Note**: Classification is automatic and based on dialectal keywords, video metadata, and linguistic patterns. Some entries may contain mixed dialects due to code-switching or regional overlap.

### Egyptian Arabic (EG)

Egyptian Arabic is the most widely understood Arabic dialect due to Egypt's large population (~100M speakers) and cultural influence through media.

**Characteristics**:
* Simplified verb conjugations (no dual forms in verbs)
* Distinct pronunciation (ج as "g", ق as glottal stop)
* Unique vocabulary (e.g., إزيك for "how are you")
* Heavy use of particles like يعني, بقى, كده

### Saudi Arabic (SA)

Includes Najdi (Central) and Hijazi (Western) variants spoken by ~30M people.

**Characteristics**:
* Preservation of classical pronunciation (ج as "j", ق as "q")
* Gulf-specific vocabulary and expressions
* Different question words (وش for "what")
* Distinct verb patterns and negation structures

## Use Cases

### ✅ Recommended Use Cases

* **Dialect Adaptation**: Fine-tune base LLMs (Llama, Mistral, Qwen) for Egyptian/Saudi understanding
* **Continued Pre-training**: Augment model knowledge with colloquial Arabic
* **Sentiment Analysis**: Build classifiers for social monitoring in Egypt and KSA
* **Dialect Identification**: Train discriminators to distinguish regional variants (EG vs SA vs AR)
* **Code-Switching Research**: Study Arabic-English language mixing patterns
* **Cultural NLP**: Analyze slang, humor, and regional expressions
* **Multi-Dialect Models**: Train models that understand multiple Arabic varieties

### ⚠️ Limitations

* **Platform Bias**: YouTube demographics skew younger and more tech-savvy
* **Topic Bias**: Over-representation of entertainment and tech content
* **Register**: Primarily informal; limited formal or professional language
* **Dialect Mixing**: Contains code-switching (Arabic-English) and occasional MSA
* **Size**: Moderate scale (150K) - suitable for fine-tuning but not pre-training from scratch
* **Temporal**: Reflects 2023-2024 language usage and cultural references

dataset = load_dataset("fr3on/arabic-dialect-corpus")

high_quality = dataset['train'].filter(
lambda x: x['score'] >= 50
)

print(f"High-quality subset: {len(high_quality)} examples")
```

## Training Examples

### Continued Language Model Pre-training

```python
from datasets import load_dataset
from transformers import (
AutoTokenizer,
AutoModelForCausalLM,
TrainingArguments,
Trainer,
DataCollatorForLanguageModeling
)

# Load dataset
dataset = load_dataset("fr3on/arabic-dialect-corpus")

# Load base model (e.g., Llama 3)
model_name = "meta-llama/Llama-3-8B"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Tokenize the data
def tokenize_function(examples):
return tokenizer(
examples['text'],
truncation=True,
max_length=512,
padding=False
)

tokenized_dataset = dataset.map(
tokenize_function,
batched=True,
remove_columns=['text', 'label', 'score']
)

# Data collator for CLM
data_collator = DataCollatorForLanguageModeling(
tokenizer=tokenizer,
mlm=False # CLM, not MLM
)

# Training arguments
training_args = TrainingArguments(
output_dir="./arabic-dialect-clm",
overwrite_output_dir=True,
num_train_epochs=3,
per_device_train_batch_size=4,
save_steps=10_000,
save_total_limit=2,
learning_rate=2e-5,
warmup_steps=500,
logging_steps=100,
fp16=True,
)

# Trainer
trainer = Trainer(
model=model,
args=training_args,
data_collator=data_collator,
train_dataset=tokenized_dataset['train'],
)

# Train
trainer.train()
```

### Using with Axolotl

Create a config file `dialect-finetune.yml`:

```yaml
base_model: meta-llama/Llama-3-8B
model_type: LlamaForCausalLM

# Dataset configuration
datasets:
- path: fr3on/arabic-dialect-corpus
type: completion
field: text

# Training parameters
sequence_len: 512
num_epochs: 3
micro_batch_size: 4
gradient_accumulation_steps: 4
learning_rate: 0.00002

# Output
output_dir: ./outputs/arabic-dialect

# Optimization
fp16: true
flash_attention: true
```

Then run:
```bash
axolotl train dialect-finetune.yml
```

### Dialect-Aware Sentiment Analysis

```python
from datasets import load_dataset
from transformers import AutoTokenizer, AutoModelForSequenceClassification

# Load dataset
dataset = load_dataset("fr3on/arabic-dialect-corpus")

# Add sentiment labels (you would need to label these)
# For demonstration, we'll filter by score as proxy
def add_sentiment_label(example):
score = example['score']
if score >= 100:
example['label'] = 2 # Positive
elif score >= 20:
example['label'] = 1 # Neutral
else:
example['label'] = 0 # Negative
return example

labeled_dataset = dataset['train'].map(add_sentiment_label)

# Train sentiment classifier
model = AutoModelForSequenceClassification.from_pretrained(
"CAMeL-Lab/bert-base-arabic-camelbert-msa",
num_labels=3
)
```

### Country-Specific Model Training

```python
from datasets import load_dataset

dataset = load_dataset("fr3on/arabic-dialect-corpus")

# Train separate models for each dialect region
dialects = ['EG', 'SA']

for dialect in dialects:
# Filter by dialect label
dialect_data = dataset['train'].filter(
lambda x: x['label'] == dialect
)

dialect_name = {'EG': 'Egyptian', 'SA': 'Saudi'}.get(dialect)
print(f"Training {dialect_name} model with {len(dialect_data)} examples")

# Your training code here
# model = train_model(dialect_data)
# model.save_pretrained(f"./models/arabic-{dialect.lower()}")

# Or train a dialect classifier
def add_dialect_label(example):
label_map = {'EG': 0, 'SA': 1, 'AR': 2}
example['label_id'] = label_map[example['label']]
return example

classifier_data = dataset['train'].map(add_dialect_label)
# Train dialect identification model
```

### Comparative Dialect Analysis

```python
from datasets import load_dataset
from collections import Counter

dataset = load_dataset("fr3on/arabic-dialect-corpus")

# Analyze vocabulary differences
def get_top_words(label, n=100):
dialect_data = dataset['train'].filter(
lambda x: x['label'] == label
)

all_words = []
for example in dialect_data:
words = example['text'].split()
all_words.extend(words)

return Counter(all_words).most_common(n)

# Compare Egyptian vs Saudi vocabulary
egypt_words = get_top_words('EG')
saudi_words = get_top_words('SA')

print("Top Egyptian words:", egypt_words[:10])
print("Top Saudi words:", saudi_words[:10])
```

## Data Collection & Processing

### Source

* **Platform**: YouTube public comments
* **Selection Criteria**: Videos with high engagement (>10K views)
* **Categories**: Talk shows, tech reviews, podcasts, entertainment
* **Date Range**: 2023-2024

* ✅ **Manual Validation Accuracy**: 94% dialect correctness
* ✅ **Text Cleanliness**: <1% non-Arabic characters

## Considerations for Using the Data

### Dialectal Arabic Characteristics

Colloquial Arabic differs fundamentally from MSA:

* **Phonology**: Different pronunciation rules (e.g., ج, ق sounds vary)
* **Morphology**: Simplified verb conjugations and case systems
* **Lexicon**: Region-specific vocabulary and loanwords
* **Syntax**: More flexible word order and dropped pronouns
* **Orthography**: Inconsistent spelling conventions

### Recommended Training Approaches

1. **Fine-tune multilingual Arabic models** (e.g., AraGPT2, CAMeL-BERT) rather than training from scratch
2. **Combine with MSA data** to maintain formal language understanding
3. **Use quality filtering** to focus on high-engagement content
4. **Consider domain adaptation** if targeting specific use cases (e.g., tech, entertainment)
5. **Augment with other dialect datasets** for broader coverage

### Code-Switching Handling

This dataset contains natural Arabic-English code-switching (e.g., "يعني basically كده"). If training a monolingual Arabic model, consider:

* Filtering or replacing English words
* Using bilingual tokenizers
* Training on code-switched data intentionally

### Ethical Considerations

* **Public Data**: All content sourced from publicly accessible YouTube comments
* **Privacy**: No personal information (names, emails, addresses) included
* **Anonymization**: Author usernames removed during processing
* **Bias Awareness**: Dataset reflects online youth culture and may not represent all demographics
* **Cultural Sensitivity**: Content filtered for extreme hate speech but may contain strong opinions
* **Intended Use**: Research and model training only; not for surveillance or profiling
