Dialogflow @sys.email entity is not identifying emails

问题

In my intent I am expecting the user to provide his/her email address.

I tried using @sys.email entity to identify the email from training phrases, but it is not identifying the email address.

What could be the issue ? When I searched the web I saw similar question being asked in some Google Groups, but could not find the answer.

EDIT:

Here is a screenshot the intent page showing Training Phrases and Actions and Parameter:

Other than the email's in screen shot I've tried with several other email id's, work and personal, It did not identify any of them.

Thanks for the screenshot, I now understand your problem and was able to recreate it.

At first, I tried similar approach and added some user phrases but did not tag them with @sys.email. DialogFlow was also not able to tag them itself, and hence it is not able to extract emails as well.

After that, I manually tagged the email address from the user phrases with @sys.email and then it worked fine.

So, tag the email addresses in the training phrases with the entity @sys.email and try again. It should work.

Hope it helps.
