Abstract
Artificial intelligence (AI) has revolutionized numerous sectors, including
higher education like universities, by offering innovative solutions to improve
service efficiency and quality. This research addresses the challenge faced by Ma
Chung University in efficiently handling student inquiries, particularly those
concerning the "Student Guide," given the limitations of human resources. The
study aims to implement an OpenAI-powered chatbot on WhatsApp, a widely-used
messaging platform among students. The Retrieval Augmented Generation (RAG)
method was employed to overcome the constraints of generative chatbots, enabling
efficient information retrieval from PDF documents. The implementation involved
the OpenAI model, the LangChain framework, and integration with the WhatsApp
API. Survey results indicated that 89.28% of the responses were positive, with the
chatbot achieving a 94.59% accuracy rate in providing factual answers and a
97.30% accuracy in document retrieval. Nevertheless, some hallucinations (4.05%)
and instances where the chatbot failed to find relevant information (2.7%) were
observed.
