Rasa slot_mappings FormAction doesn't as intended with SpaCy pretrained NER

,

Hi, I’m writing a simple chatbot where it requests the user’s data and fills some slots, similar to the restaurant formbot. The problem is that when I declare a custom slot “firstname” and try to map the extracted PERSON entity from spacy, it only works when firstname is expected (SEE EXAMPLE BELLOW) !

My setup

intents:

  • greet: use_entities: []
  • goodbye: use_entities: []
  • request_data: use_entities: []

entities:

  • PERSON
  • ORG
  • GPE

slots:

firstname:

type: unfeaturized

auto_fill: false

utter_ask_firstname:

  • text: “What’s the person’s first name? firstname: {firstname}” utter_slots_values:
  • text: “Registered employed with the following parameters firstname: {firstname}”

and story

data input

  • request_data
    • employee_form
    • form{“name”: “employee_form”}
    • form{“name”: null}
    • utter_slots_values

intent:request_data

  • I wanna register a person
  • Register
  • John
  • first name John
  • Firstname is John
  • register John

actions.py

def slot_mappings(self) -> 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"""
    slot_map = {
        "firstname": self.from_entity(entity="PERSON"))
    }
    return slot_map

If I type:

Me: Register

Bot: What’s the person’s first name?

Me: John

Bot: “Registered employed with the following parameters firstname: John”

but if I type

Me: Register John

Bot: “Registered employed with the following parameters firstname: none”

BUT

When I declare the slotname as PERSON, the bot works as expected! It seems that the line slot_map = { “firstname”: self.from_entity(entity=“PERSON”)) }

in order to work as expected, the key in slot_map dict should be an entity already (in our case PERSON)! But this is not practical at all since I want to have one PERSON entity and fill many slots with this value.

This seems like a bug to me! Has anyone run into this?

Hi there, can you post the logs from --debug mode of your rasa server and your action server?
