Entity exttraction

Hello, I want to extract number from an intent like i have my intent as:

intent: data

So, how can i extract such kind of number which i don’t know what user gives? Thanks in advance:)

Well, you already named it in the topic

If its always as structured as in your examples, a simple regex will do it too

EDIT: And for RASA to identify it as an entity it has to be marked as an entity in the training data
