R2GQA: Retriever-Reader-Generator Question Answering System to Support Students Understanding Legal Regulations in Higher Education

Introduction

R2GQA is an automated question answering system developed to help students better understand legal regulations in higher education. The system combines advanced methods in information retrieval and answer generation, including:

• Searching for relevant context from legal document databases
• Extracting precise answers from question and context
• Generating natural, user-friendly responses

This project is part of research published in the paper R2GQA: Retriever-Reader-Generator Question Answering System to Support Students Understanding Legal Regulations in Higher Education.
