Guiding Users
Guiding Users
Implicit Confirmation
Implicit confirmation involves repeating details back to the user to reassure them that they were understood correctly. This also gives the user a chance to intervene if your assistant misunderstood.
Example:
User: Can I get a large hawaiian and bbq pizza
Assistant: Sure, that's one large hawaiian and one regular bbq pizza.
User: Anything else?
Assistant: No they should both be large!
Explicit Confirmation
Explicit confirmation means asking the user to clarify how you should help them. An important thing to remember about AI assistants is that the user is never wrong. When a user tells you something like I just moved, they are being perfectly clear, even if your assistant is not sure how to help them. If the user goal is ambiguous to your assistant, ask for clarification.
Example:
User: I just moved
Assistant: I'm not sure I understood you correctly. Do you mean ... ?
User: I want to cancel my contract
User: I want to update my personal details
Assistant: You can configure the TwoStageFallbackPolicy to ask your user to clarify, and present them with quick replies for the most likely intents.
Policy Configuration Example:
policies:
- name: TwoStageFallbackPolicy
nlu_threshold: 0.3
core_threshold: 0.3
fallback_core_action_name: "action_default_fallback"
fallback_nlu_action_name: "action_default_fallback"
deny_suggestion_intent_name: "out_of_scope"
...```
## [Explaining Possibilities](https://legacy-docs-v1.rasa.com/1.10.21/dialogue-elements/guiding-users/#explaining-possibilities)
AI assistants are limited to helping users with a specific set of tasks, and should be able to explain to a user what they can do. This includes coherently responding to requests that are out of scope.
**Example:**
*User:* What can you do?
*Assistant:* I can help you update your personal details, change your plan, and answer any questions you have about our products.
*User:* Can you get me a pizza?
*Assistant:* I'm afraid I can't help with that.
### When to Explain Limitations
```yaml
## user asks whats possible
* ask_whatspossible
- utter_explain_whatspossible
## user asks for something out of scope
* out_of_scope
- utter_cannot_help
- utter_explain_whatspossible
Collecting User Feedback
Asking for feedback is one of the best tools you have to understand your users and determine whether you solved their problem! Storing this feedback is a powerful way to figure out how you can improve your assistant.
Example:
User: Was that helpful?
Assistant: no.
Assistant: Thanks. Why wasn't I able to help?
User: you didn't understand me correctly
User: you understood me, but your answers weren't very helpful.
Form to Collect Feedback
To do this, define a custom form action:
from rasa_sdk.action import FormAction
class FeedbackForm(FormAction):
def name(self):
return "feedback_form"
@staticmethod
def required_slots(tracker):
return ["feedback", "negative_feedback_reason"]
And add the form to your domain:
forms:
- feedback_form
slots:
feedback:
type: bool
feedback_reason:
type: text
requested_slot:
type: text
Ensure the FormPolicy is present in your configuration file:
policies:
- FormPolicy
...
Handing off to a Human
Users will be frustrated if your assistant cannot help them and there is no way to reroute the conversation to a human agent. There should always be a way to break out of a conversation!
Reasons for Handoff:
- the user asks to speak to a human
- the assistant is struggling to understand the user
- the assistant understands what the user wants, but a human is required to resolve the issue.
Example:
User: let me speak to a human
Assistant: let me put you in touch with someone.
User: I want to cancel
Assistant: I'm afraid I can't help you with that.
Assistant: let me put you in touch with someone.
Policy to Handle Human Requests:
intents:
- request_human: {"triggers": "action_human_handoff"}
