+# Hindawi Arabic Books — Sections Dataset
+
+A cleaned, section-level dataset of Arabic books from [Hindawi.org](https://www.hindawi.org), prepared for NLP training and research.
+
+## Dataset Description
+
+- **Language:** Arabic
+- **Level:** Section-level (each row = one book section)
+- **Text format:** Single-line, cleaned Arabic text
+- **Total sections:** 52,830
+- **Total books:** 3,265
+- **Total characters:** 843,868,321
+- **Mean chars / section:** 15,973.3
+- **Median chars / section:** 7,915.0
+- **Min chars / section:** 250
+- **Max chars / section:** 723,964
+- **Sections < 500 chars:** 1,593 (3.02%)
+
+## Source
+
+Original books scraped from [Hindawi.org](https://www.hindawi.org), a non-profit foundation providing free Arabic books. The dataset covers categories including literature, philosophy, history, science, psychology, and more.
+
+## Cleaning Pipeline
+
+1. **Scraped** book content section-by-section from Hindawi.org
+2. **Removed English / Latin** text and characters
+3. **Removed tashkeel** (Arabic diacritics: َ ُ ِ ْ ّ etc.)
+4. **Removed tatweel** (kashida: ـ)
+5. **Normalized Arabic letters:**
+   - `أ` `إ` `آ` `ٱ` → `ا`
+   - `ى` → `ي`
+   - `ة` → `ه`
+6. **Deduplicated** exact duplicate lines and near-duplicate paragraphs (فرهس)
+7. **Replaced Eastern Arabic numerals** (`٠١٢٣٤٥٦٧٨٩` and `۰۱۲۳۴۵۶۷۸۹`) with Western `0-9`
+8. **Collapsed** each section to a single line (newlines → spaces)
+9. **Filtered** sections with fewer than 250 characters
+10. **Cross-book deduplication:** removed 342 sections that were >95% similar to sections in other books (3,253 duplicate pairs found, mean similarity 99.79%)
+
+## Splits
+
+| Split      | Rows    | Percentage |
+|------------|---------|------------|
+| train      | 47,546 | 90.0% |
+| validation | 2,642 | 5.0% |
+| test       | 2,642 | 5.0% |
+
+Split was done with `train_test_split` from scikit-learn with `random_state=42` and `shuffle=True`.
+
