In this solution Chatterbot is a machine learning-based chat bot engine. The bottom layer is mainly Python language, which can learn from existing conversations or train any language independently. The ORAI software currently includes this chat bot. Users only need to run the py file through the graphical interface to learn from a given conversation and reply to the corresponding response in the corresponding situation. In addition, we also integrate ChatterBot with CGI. After learning the corpus in advance, we only need to input the statement through the browser to get a relative response.
