ASK SIT is an intelligent assistant (AI Chatbot) developed to provide fast and accurate answers and information related to the School of Information Technology (SIT), KMUTT. The system utilizes Retrieval-Augmented Generation (RAG) technology in combination with a Large Language Model (LLM) to retrieve in-depth information from curriculum documents (PDFs) and the faculty’s website in real time. In addition, it includes a Human Handover (Ticket System) that forwards questions the AI cannot answer to administrators, enhancing the overall experience of accessing information for students and the general public efficiently.
