Leveraging Graph Retrieval-Augmented Generation to Support Learners' Understanding of Knowledge Concepts in MOOCs

Understand

Massive Open Online Courses (MOOCs) lack direct interaction between learners and instructors, making it challenging for learners to understand new knowledge concepts.

• Recently, learners have increasingly used Large Language Models (LLMs) to support them in acquiring new knowledge.
• However, LLMs are prone to hallucinations which limits their reliability.
• Retrieval-Augmented Generation (RAG) addresses this issue by retrieving relevant documents before generating a response.
