Hi

How to define a slot to identify a number like credit card number? in one example mentioned below, give an example to identify color, but it only recognize colors mentioned in the story only. when we give a different color, rasa could’t recognize it and it doesn’t respond. for a scenario like credit card balance, we cant add all the possible numbers even though we can for colors, how can we remember numbers? how to remember chat context?

Thanks Prashath

Hello prashath,

give an example to identify color, but it only recognize colors mentioned in the story only.

This might be because you don’t provide enough data/example (different colors) in your nlu.md. I have faced similar situation before and after providing a sufficient amount of example, the bot can pick up entities which are not in stories.

for a scenario like credit card balance, we cant add all the possible numbers even though we can for colors, how can we remember numbers?

You can do the same as i said above plus using regex features in addition. You can read about Regex features here: NLU Training Data

Those are my experience after working with identifying date entities.
