The way it works:

• You supply FAQs in the form of csv (comma separated file) having Question-Answer-Class in each row (e.g. "What is GST rate for Toothpaste?,12,rate")
• Questions are vectorized and kept ready for matching, along with the classifier model [X=vector(question), y=class]
• Once user query comes, its 'class' is predicted using the classifier model and within the class, vectorized query is matched against existing vectorized questions.
• Whichever is most similar, it's answer is presented to the user.
