I am new to Rasa NLU and I wanted to know how do we extract entities in stories regardless of their value. For example, I want to ask the user his location and then extract the entity “location” from their reply and pass it to a custom action/template.

my stories.md file :

## emergency path

- greet
  - utter\_greet

- inform
  - utter\_ask\_location

- tell\_location
  - utter\_affirm\_location

- accept
  - utter\_goodbye

I want to extract the entity in the tell\_location intent. looking forward for insight. 🙂

you must use slot that looks like the memory of your bot here you can name it as location . I think that help you a lot [Domain](https://rasa.com/docs/rasa/core/slots/)

@hajoura thank you for your response. I tried slots but i don’t want to hardcode key-value pairs. I want the slot in tell\_location regardless of the value. The below example works fine but I do not want to define the value and fire utter\_affirm\_location.

- tell\_location {“location”: “pakistan”}
- utter\_affirm\_location

Hi @taimoor-ahmed,

If I understood you correctly you want to fill the tell\_location slot regardless of the value. The best way t do it is to have a well trained NER for locations (spacy got one for english). Another way to do it (but I think it’s not the best choice) is to custom fill the slot through forms. You can do a custom slot mapping, and fill a slot with the users input (check [here](https://rasa.com/docs/rasa/core/forms/#custom-slot-mappings)).

It would look something like this:

```
 def slot_mappings(self):
        # type: () -> Dict[Text: Union[Dict, List[Dict]]]
        """A dictionary to map required slots to
            - an extracted entity
            - intent: value pairs
            - a whole message
            or a list of them, where a first match will be picked"""

        return { "tell_location": [self.from_text()] }

```

This way your slot will be filled with any string given by the user.

Hope it helps.

@BrunoRoth95 thank you for your response. I’ll try to implement your solution and let you know if I got it right.

Just curious, if I get these values from user

tell\_location {“location”: “chicago”}

tell\_location {“location”: “new york”}

tell\_location {“location”: “seattle”}

tell\_location {“location”: “trenton”}

but some of these values are not even defined in my stories.md file

- tell\_location {“location”: “new york”}
  - utter\_ask\_confirm

- tell\_location {“location”: “seattle”}
  - utter\_ask\_confirm

How would this work for missing values? Do we end up adding all the possible locations is a good idea or AI would understand and interpret accordingly?
