NLU not detecting phrases in the model

[Yasmin]

NLU is not detecting phrases that previously exist in the model. As an example, one of the phrases is "return my assets". When typing the exact same phrase it doesn't return any topics in VA UI.  Any advice how to improve this? Perhaps this is a glitch that came with Patch5?

Sometimes when just testing phrases, we get the following black error:

Appreciate any advice to help identify what could be causing these errors.

Thanks!

Hi Yasmin,

Can you please trying doing cache.do . Secondly, try publishing the model and try testing on the Service Portal.

If it doesn't workout, try to create a fresh model and import the intents from here.

Last resort is to raise a HI ticket as it doesn't seem a configuration issue.

Thanks Hardit. I checked with our developer and did the cache.do on one of the environments. Could not do it in all because it could affect performance and others in IT working on the platform.

Still didn't see improvement on the model. I'm having to check utterance by utterance on some of the critical intents to detect which ones are not being detected even though the exact phrase is being typed.

Before Patch 5 I noticed in itdev and uat environments that when testing a phrase we would get the pink ribbon with no error message. this would show once or twice in a day. And when trying to train the model an error would show maybe once  saying "Unable to train the model at this time. Please try again later" but when training a 2nd time (without making any changes in the model) the message would disappear. So this is intermittent.

Any ideas what those error messages appear?

Hey Yasmin! 

I've also started to notice odd behavior since Patch 5. For example, Utterances that match the confidence threshold are not being pulled by the Virtual Agent, some VA Topics always having the "Draft" tag after saving and publishing multiple times, and things of that nature. 

May I ask if you uncovered anything relating to your issue above or not so much?

Hi Oelrafik, 

I see the same happening on my end after recently. Phrases are recognized when testing the model, yet the VA UI won't recognize the phrase. Even phrases that are typed exactly the same as per the phrase in the model. I've noticed that not all utterances in an intent are recognized any more, but they were in the past.  I added some comments on the reply form Hardit above. Let you know if any progress from my end today.

About the topics showing in "Draft" after being saved and published, I've seen that before Patch 5. It's like something is hanging not allowing the topic to be updated.

Regards.
