Need help with better entity recognistion

Hello,

Need help regarding entity extraction to fill slots in the response template. As I am new to Rasa and NLP. I am wondering is there any great way to extract entities better. like I have an intent.

intent:greet

  • Hey, I am [Rakesh ] (name)

and in domain file.

slots:

name:

type: text
initial_value: "Rakesh"

template:

 utter_greet:
  • text: “HI {name}”

SO I need to replace it with another value : {name}—> jackson. When I type: Hey, I am jackson.

How can maximize this kind of results. What need to be added in SPAcy and tensorflow or MITAE. to achieve this. Thank you.
