Cite or Decline: A Strict Course-Grounded Chatbot for STEM Lecture Videos

A retrieval-augmented chatbot, developed as part of the VideoPoints platform, has been successfully deployed for a semester to support STEM lecture videos. This chatbot exclusively uses course-specific lecture materials to answer student queries, providing timestamped citations and demonstrating a high rate of declining to answer when no relevant evidence is found, thus maintaining content integrity and relevance.

This development is significant as it demonstrates a practical application of AI in educational resource delivery, addressing the challenge of content veracity and relevance. For organizations relying on large volumes of domain-specific information, it highlights a model for building highly accurate and auditable AI-powered knowledge retrieval systems, mitigating risks associated with untrustworthy or out-of-domain information.
