Usage

Loading the Dataset

Available on Hugging Face Hub

Python (Recommended)

import json

# Load the main dataset
articles = []
with open('arabic_wikipedia_cleaned.jsonl', 'r', encoding='utf-8') as f:
    for line in f:
        article = json.loads(line)
        articles.append(article)

print(f"Loaded {len(articles)} articles")

Hugging Face Datasets

from datasets import load_dataset

# Load from Hugging Face Hub
dataset = load_dataset('Jr23xd23/rightnow-arabic-llm-corpus')

# Or load from local files
dataset = load_dataset('json', data_files='arabic_wikipedia_cleaned.jsonl')

Data Format

Each line in the JSONL file contains:

{
  "id": "unique_article_id",
  "title": "Article Title",
  "text": "Clean Arabic text content...",
  "url": "source_url",
  "hash": "content_hash",
  "metadata": {
