Expert Feedback Loop suddenly has No Data anymore

[davidwild]

I used to have over 300 records to work on here. In January of this year it updated and then again in March. I was able to see those records for a few months. Now as of two weeks ago I get the screen that says "No Data Yet." I have not changed the model and I am scratching my head as to why all these previously uncategorized utterances, suddenly disappeared. Could it be that everything resets after 30 days and I lose all the uncategorized utterances?!

According to the documentation for NLU's Expert Feedback Loop, there is a scheduled job running every 30 days that collects records to display in this module.
Another possibility could be a recent clone over the instance.

🔍 What’s Likely Happening:

• NLU Analytics logs (like uncategorized utterances) are stored temporarily.

• By default, these logs are retained for only 30 days unless your instance has customized the retention settings.

• So if you haven't exported or categorized them, they get purged automatically after that window.

  ✅ What You Can Do:

  1. Check Retention Settings:

     • Go to: System Properties > NLU Analytics

     • Look for properties like nlu.analytics.retention_days

     • Update this value to retain utterances longer (e.g., 90 or 180 days).

  2. Use Scheduled Exports:

     • Set up a scheduled job or integration to export uncategorized utterances regularly before they expire.

  3. Check Access Role or View Filters:

     • Just in case, confirm your current user role still has access to view uncategorized utterances in the NLU Workbench.

  💡 Best Practice:

  If you’re actively training your model, review and tag utterances weekly and export frequently if you need audit or backup.
