Hi rishabh,

you can refer to this article [https://blog.rasa.com/improving-entity-extraction/](https://blog.rasa.com/improving-entity-extraction/).

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.
