# Arabic Reverse Dictionary Dataset

## Overview

We present a novel Arabic Reverse Dictionary (RD) dataset comprising over 58,000 definitions collected from trusted, open-source books and websites. To the best of our knowledge, this is the first open-source Arabic reverse dictionary dataset available to the research community.

## Dataset Construction

The dataset was developed through multiple extraction methods:
- Direct extraction from PDF text for some sources
- Optical Character Recognition (OCR) using advanced models (Gemini and Mistral) for other sources
- All definitions were subsequently reconstructed using GPT-4o to ensure consistency and clarity in the final dataset

## Dataset Statistics

- **Total definitions**: ~58,000
- **Average definition length**: 13.64 words
- **Average word length**: 1.52 words
- **Topics covered**: Islamic studies, linguistics, mathematics, science, psychology, engineering, and more
