Active Learning suggestions will not appear immediately after turning the feature on in the portal. They'll appear after the qna model has received enough feedback to offer up a suggestion.
See comment I wrote back in Feb of last year regarding how suggestions are trigged and when they'll show up in the portal, in MS Docs discussion for full context of the conversation. But the main thing is this:
When there is a low confidence score difference between the top answers, we collect weighted implicit and explicit feedback to cluster suggestions for any QnA ID.
=> When enough feedback is collected for any given suggestion, it will show in the KB.
More specifically, we cluster similar user queries to generate suggestions. When minimum required feedback is collected, only then will the suggestions show in the KB.
The QnA team wants to avoid publicly divulging the exact logic of what
exactly is the "minimum required feedback" and how often suggestions
are generated (besides, the team is working on improving and
optimizing the logic behind active learning as well)
--however to see suggestions appear in the qnamaker.ai portal:
- not only ensure that you've given the bot enough feedback
- but also
give the back end "some time" to allow for the suggestions to appear
in the portal. Again, feedback is collected when your user types in a
query that returns answers from QnA that have confidence scores that
are close together.
It is also good to note that feedback is not collected in the Test
panel in the qnamaker.ai portal as of now. You will need to chat with
your bot via emulator or a channel to provide feedback to your bot
that it can use for active learning.
