Multi-Domain Question Answering Dataset

Overview

The Multi-Domain Question Answering Dataset is a large-scale educational and knowledge corpus designed for training Large Language Models (LLMs), Retrieval-Augmented Generation (RAG) systems, educational AI assistants, enterprise knowledge systems, and intelligent question-answering applications.

The dataset contains millions of multiple-choice question-answer pairs spanning numerous academic, professional, technical, and general knowledge domains. Each sample includes answer options, the correct answer, and a detailed explanation, making it suitable for reasoning, instruction tuning, and supervised fine-tuning.

The dataset is available in both structured JSON and PDF formats.
