AI-102 Practice Question: Implement natural language processing solutions
A company is building a chatbot using Azure Bot Service and Language Understanding (LUIS). The chatbot needs to handle user intents for booking flights and checking flight status. After testing, the chatbot frequently fails to distinguish between the two intents when users mention flight numbers. Which action should the engineer take to improve intent recognition?
⚠ Common exam trap
Watch out — candidates often think reducing the confidence threshold or adding more intents will fix misclassification, but the real issue is insufficient representative training data for the specific ambiguous patterns (flight numbers) that cause confusion.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add more utterances that include flight numbers to the training data for both intents.
Adding more utterances that include flight numbers to both intents provides LUIS with more varied examples of how flight numbers appear in natural language, enabling the model to learn distinguishing patterns. Without sufficient training data containing flight numbers, LUIS cannot reliably differentiate between 'BookFlight' and 'CheckFlightStatus' when users mention flight numbers, as the entity alone does not determine intent.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the number of intents to split the flight-related queries further.
Why it's wrong here
More intents can dilute training data and increase confusion.
- ✓
Add more utterances that include flight numbers to the training data for both intents.
Why this is correct
This provides more examples for the model to learn the subtle differences.
- ✗
Reduce the confidence score threshold for intent detection.
Why it's wrong here
Lowering threshold increases false positives, not accuracy.
- ✗
Use the prebuilt domain for flight booking to improve accuracy.
Why it's wrong here
Prebuilt domains may not cover all custom scenarios.
