Hello, dear colleagues!

 

I was searching for the source of the statistics displayed on the NLU Model Performance for Virtual Agent

bars (screenshot attached to this post), but I couldn't find it. I need to replicate that data on a dashboard. 

 

Does anybody know the table/Indicator name that produces those statistics?

Hi @gustavocami,

These NLU performance stats are not coming from a single direct table, which is why it’s hard to find them straight away.

They are mainly derived from Virtual Agent conversation data, specifically:

  • sys_cs_conversation
  • sys_cs_conversation_turn
  • sys_cs_intent / sys_cs_intent_match (depending on version)
  • NLU prediction + user confirmation data stored during VA interactions

The key part is the user confirmation step (correct / incorrect / no response), which gets captured as part of the conversation turns and is then aggregated for this report.

For dashboard replication, what you can do is:

  1. Start with sys_cs_conversation_turn
  2. Filter on:
    • NLU prediction events
    • Confirmation responses (Yes/No/No input)
  3. Build indicators like:
    • Confirmed correct
    • Confirmed incorrect
    • No confirmation

Note: The UI you’re seeing is powered by internal aggregation (not a ready-made PA indicator), so you’ll need to recreate the logic using conditions on these tables.

If you're using Performance Analytics, you can create scripted indicators based on these conditions.
