AI ChatBotPT, which is experimental at the University Earning Center, utilizes a traditional rule-based two-way interactive AI chatbot(Machine Learning)-based platform. In addition, API agent-based AIChatBot is in progress with conversational service open platforming and language understanding technology, and AI technology comparable to human capabilities is being developed in areas such as voice/video/multilingual recognition. Voice AI ChatBot needs to build big data learning for the verification of unsupervised learning in the answer stage. In the future, it is necessary to provide AI ChatBot service for university learning knowledge data lake by building big data by academic field/department.
