Chatbot is artificial intelligence software that can simulate the conversation between the human and the system. The chatbot is widely used in areas such as customer support, banking, health care, and educational institutions to simplify the interaction between humans and systems. It not only saves money and time for the users but also brings new opportunities to improve their business. Hence, this paper discussed two approaches such as the pattern matching approach and the machine learning approach to develop a chatbot. The pattern matching approach represents a question answering system which formulates responses to questions in human language. The machine learning approach uses training data and natural language processing to train systems to answer the user’s query. The machine learning approach is more efficient than pattern matching. This paper demonstrated the development of a chatbot for college website is essential for the providing the round the clock information to the students or the visitors of college website.
