How to extract any/all string name from the intents? In between character a-z A-Z of 1,2,3 words. Because a users name can be anything.

  • intent: inform examples: |

    • my name is [shashank]{“entity”:“name”}
    • [shashank]{“entity”:“name”} is my name
    • [shashank]{“entity”:“name”}
    • i am [shashank]{“entity”:“name”}
    • myself [shashank]{“entity”:“name”}
    • [shashank]{“entity”:“name”} this side
