[Solved] RASA FormPolicy

Rasa Open Source
1

Hi guys, so currently i use rasa core version 14.5, and i tried to use form policy where the bot will ask person name from it, and from slot_mappings function:

def slot_mappings(self):
        return {
            "person_name": [
                self.from_text()
            ]
        }

but it doesn’t extract the text, the bot still using the fallback policy, is it the expected behavior? Cause i can’t use from_entity(), NLU cannot extracted 1 word or 2 words name in my model right now, already trained 1 word or 2 words name in the NLU. Thanks!

Hi @yaput,

I think that you are mentioning several issues. The most important one first:

Could you provide more information about your setup:

  • the rest of the actions.py
  • domain content
  • nlu content

Such that I could really help you?

Regards

Hi @JulianGerhard thanks for responding, here the setup that i use:

  • custom action form:
class DoctorNameForm(FormAction):
    def name(self):
        # type: () -> Text
        """Unique identifier of the form"""
        return "doctor_name_form"
    
    @staticmethod
    def required_slots(tracker):
        return ['doctor_name']
    
    def slot_mappings(self):
        return {
            "doctor_name": [
                self.from_text()
            ]
        }
    
    def validate_doctor_name(self,value, dispatcher, tracker, domain):
        print(value)
        doctor = doctors.fetchDoctorByName(value)
        if not doctor['status']:
            dispatcher.utter_template('utter_inccorect_doctor', tracker)
            return None
        return {'doctor_name': value}

    def submit(self, dispatcher, tracker, domain):
        lang = tracker.get_slot('language')
        doctor = doctors.fetchDoctorByName(tracker.get_slot("doctor_name"))
        if not doctor['status']:

    sentences with person name as the entity, and using lookup for synonyms(this for intent with the doctor_name or person name itself).

Hi,

okay, let’s try something else. Start the bot by running:

rasa run -vv -m <path_to_model> --endpoints endpoints.yml --credentials credentials.yml --enable-api

After that, do a POST request with the body:

{
	"text": "I want to visit Lubab"
}

to

http://localhost:5005/model/parse

and post the result here! We could then at least figure out from where the problem comes.

Besides: Could you show me your stories aswell? The action form seems to be valid.

Okay, at least the parsing result is as expected. Can you post your config.yml please? Sorry for forgetting that in my last response.

And also the NLU is doing great, but the problem is whenever the form is activated, then the bot will trigger utter_ask_slot_name for ex: “Can you tell me the doctor’s name?” then the slot_mapping() will use self.from_entity(entity="doctor_name"), then when user type the doctor name: “Lubab”, it will not extract the entity of doctor name, and not intent book_appointment, i assume because it’s a word input.

Okay, could you please do an experiment:

  1. Backup your stories.md and empty it afterwards. Fill in:

  • book_appointment

    • doctor_name_form
    • slot{“requested_slot”: “doctor_name”}
    • form{“name”: “doctor_name_form”}
    • form{“name”: null}
    • action_restart

  • book_appointment{“doctor_name”: “Lubab”}

    • doctor_name_form
    • form{“name”: “doctor_name_form”}
    • form{“name”: null}
    • action_restart
  1. Modify domain.yml:

Change:

doctor_name:
    type: text

to

doctor_name:
    type: "unfeaturized"
    auto_fill: 0
  1. Change slot mapping

Change

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

to

return {
    "doctor_name": [
        self.from_entity(entity="doctor_name")
    ]
}
  1. Retrain
  2. Start Action Server and Rasa an say: a. I want to visit a doctor -> Luba b. I want to visit Lubab

and tell me about the results.

It doesn’t recognize the 1 word input such as person name, maybe i need to configure it somewhere?

Hey,

it worked as expected - I think you typed in “Luba” instead of “Lubab” in the first sample. In the second example you see, that it triggers the form, extracts the entity and finished the form without a proper utterance - but only because there is none defined - you could do that if you want to, some do it with “utter_slot_values”.

I think the main problem lies in your story design you previously posted. Your training and extraction works fine. If you define an entity the way you did it, the problem won’t ever be 1 or 2 words…

Regards

Oh yes, i also tried it again with ‘Lubab’ and same result and no entities extracted 2019-06-13 11:40:54 DEBUG rasa_core.processor - Received user message 'lubab' with intent '{'name': 'user.needs_advice', 'confidence': 0.5504515171051025}' and entities '[]'

I tried with self.from_text() but FallbackPolicy takes over when the NLU threshold is not meet and action_default_fallback triggered.

13

@yaput Did you try to add some more one / two words examples to your NLU? Are the one/two word examples that are explicitly defined in your NLU (anna Jacob e.g.) working?

14

Hi @rbossie , yup, bot only for some name only, not all of them, cause i’m hopping rasa nlu will query it from lookup file, but after i add more to the training data like: anna, jacob, ali only, and it’s working now.

So the answer for my issue is: add the entity to the training data(peter, jacob, anna, etc). Once it’s added, then NLU will recognize it.

15

I guess there needs to be some sort of balance there, according to the following notion in the Rasa docs: http://rasa.com/docs/rasa/nlu/training-data-format/ (bottom of the page)

For lookup tables to be effective, there must be a few examples of matches in your training data. Otherwise the model will not learn to use the lookup table match features.

So I would suggest to play with the number of examples defined in the NLU to get the right amount of examples and still profit from the lookup table

Yup, noticed about that, like you said, i have to play with the number of examples. Thanks for your help. Cheers :smiley:
