I am new to Rasa framework,I am trying to create a chat bot.How can I train NLU model on business specific terms and acronyms?

Example:Banking uses following acronyms that are not part of English language




Hi rishabh,

you can refer to this article

You will have to train nlu on your custom words, for that you can use the lookup table if you have unusual business words for same slot. I have used it and It works perfectly.
