@sakshi14

domain.yml

responses: utter_show_detail:

  • text: Thanks {name}! for the Email id {email}. How can I help you!

actions: action_show_detail

action.py

class ActionDetailt(Action):

 def name(self) -> Text:
     return "action_show_detail"

 def run(self, dispatcher: CollectingDispatcher,
         tracker: Tracker,
         domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
        
     name=tracker.get_slot("name")
     email=tracker.get_slot("email")

     dispatcher.utter_message(template="utter_show_detail")
     
     return []

You need to create the intent in nlu.yml, mention the Intent, Entities, Slots in domain.yml and create the story for the bot/user conversation.

I guess you want this only?

@sakshi14 Hi! Your query is solved?

No …My query still not solved

sounds more like an entity extraction problem over a slot set problem. Do you mean that the NLU model isn’t able to extract names based on the training you have done. Did you use DIET?

Names are incredibly hard and i wouldn’t rely on an extractor for names to work perfectly because they don’t have any definite pattern. Probably best if you can use lookup tables… if your namelist is finite in nature.
