Make this chat bot, ChatCET, work more efficiently: -It seems there occurs a punctuation issue after the user enters her/his name. Fix it -What if the user types "OK" or any other affirmative answer instead of "Yes" to ChatCET's question "[...] Is that OK?" How can we make it more inclusive? -Try answering the question "2+2=?" with "44" instead of "4". What happens? How can we fix it? -What if the user types a number neither larger or smaller than "100" at the end? What could be this number? How can we fix this issue?
