Trouble getting name found in Topic.

I have a "Who is" topic in my bot for looking up information about a contact named "Who Is":

The trigger phrases are 

  • Who is
  • Who is the employee Frank Zappa?
  • Show me details about Bill Smith.
  • Contact details for James Smith.
  • Show me Frank Zappa.
  • Give me details about Bill Smith.
  • Who is John Galt?
  • Who is Dieter Contoso?


This should use person entity slot filling but when I use a name that isn't in one of the specific trigger phrases,

"Who is Boris Smith?"

I get an error "Sorry, I am not able to find a related topic.  Can you rephrase and try again?"

I have turned off all other topics.

Please advise.

I have just started to look at this myself. I dont think the trigger phrases will populate an entity.

I think it only happens in response to a question just like you did where you select persons name as identity.


If you remove the names from the trigger phrases it should trigger





That is exactly how slot filling should work.  If I use one of the specific trigger phrases I list like "Who is John Galt?" , "John Galt" is filled into the person name slot and I'm not asked for it again.


"One fundamental aspect of natural language understanding is to identify entities in a user dialog. An entity can be viewed as an information unit that represents a certain type of a real-world subject, like a phone number, zip code, city, or even a person's name."



I have found that this is the same with the email entity slot filling.

If I use the exact email used in the trigger phrases, slot filling works, otherwise it does not.

 Thanks for working through this, it seems like it's the 'answer' for now, even though it's crazy that you have to add everything into both the trigger phrase and the custom entity.  I was trying an idea similar to yours and hit my head against the wall before finding this.  Thanks again!

Hi guys,


Yes, we have some limitations that we need to fill data inside the trigger phrase when we have a little phrase.

I recommend you to use System Fallback to improve your experience and wait for this planned feature here maybe will solve that you need.
