NLU Performance

Version badge

The NLU Performance Dashboard provides valuable insights into the performance of your AI Agent's natural language understanding (NLU) capabilities. It allows you to monitor and enhance message comprehension, Intent recognition, and execution efficiency. Moreover, it offers easy access to resources like the Intent Trainer for further performance improvement.

You can find more information about our NLU and Intents in the NLU Overview article.

The NLU Performance data of your AI Agent is visualized in the following charts:

These charts display all data based on the global filter and local filter settings.

Indicators

The Indicator charts presents real-time data that refreshes every 30 seconds.

Understood Messages

Displays the percentage of messages understood during conversations. You can find a calculation example with data visualization in the Understood/Misunderstood bar chart.

Average Execution Time

Displays the average execution time across a specific timespan.

Formula:

Average Execution Time = Sum of Execution Times / Total number of inputs

You can find a calculation example with data visualization in the Average Execution Time line chart.

Avg Intent Score

Displays the average Intent score for the selected time frame. Higher Intent scores indicate better AI Agent performance in matching user queries. For more information, see Machine Learning Intents.

To find the average intent score, Insights sums up all the intent scores and divides the sum by the total number of records.

Source table:

| Analytics Record | Intent Score |
| ---------------- | ------------ |
| Record-1         | 0.30         |
| Record-2         | 0.90         |
| Record-3         | 0.10         |
| Record-4         | 1            |
| Record-5         | 0.20         |
| Record-6         | 0.02         |
| Record-7         | 0.50         |
Calculation:

  1. Sum of Intent Scores = 0.30 + 0.90 + 0.10 + 1 + 0.20 + 0.02 + 0.50 = 3.02
  2. Number of Records = 7
  3. Average Intent Score = (Sum of Intent Scores) / (Number of Records)
  4. Average Intent Score = 3.02 / 7

Result: 0.43

Max Intent Score

Indicates the number of Intents that were matched with 100% efficacy.

Source table:

| Analytics Record | Intent Score |
| ---------------- | ------------ |
| Record-1         | 0.30         |
| Record-2         | 0.90         |
| Record-3         | 0.10         |
| Record-4         | 1            |
| Record-5         | 0.20         |
| Record-6         | 0.02         |
| Record-7         | 0.50         |

Result: In the provided source table, there is one record with an intent score of 1, so the max intent score is 1.

Bar charts

Understood / Misunderstood Messages

Displays the percentage of messages understood and misunderstood by the system over a selected time frame.

A message is counted as understood if it has triggered an Intent, a slot is matched, or it is marked as understood via the Code Node or Overwrite Analytics Node. A message is not counted as understood if it is marked as Don't count in the Overwrite Analytics Node or sent during an active handover without configuring LA AI Copilot Flow.

By clicking vertical-ellipsis, you can select the Go to Intent Trainer, which will take you to the application in Cognigy.AI for improving your Flow and Intents. For more information, see Intent Trainer.

| TOTAL      | 49           | 51              |                 |

Calculation for the selected timeframe:

  1. Misunderstood % = (51 / 100) * 100 = 51%
  2. Understood % = (49 / 100) * 100 = 49%

Calculation example for the date 2023-09-15:

  1. Misunderstood % = (18 / 47) * 100 = 38%
  2. Understood % = (29 / 47) * 100 = 62%

Result:
