AI-102 Practice Question: Implement natural language processing solutions
A developer is using Azure Cognitive Service for Language to perform sentiment analysis on customer reviews. The service returns sentiment labels (positive, negative, neutral) and confidence scores. For a particular review, the service returns 'positive' with a confidence score of 0.55. The developer wants to ensure that only high-confidence results are used. What should the developer do?
⚠ Common exam trap
Many exam-takers assume they can retrain the prebuilt sentiment model (Option B) or use a different API (Option A) to solve the confidence issue, when in fact the correct solution is a simple application-level threshold check.

Correct answer & explanation
✓
Configure a minimum confidence threshold of 0.75 in the application logic.
The developer must implement a confidence threshold in the application logic to filter out low-confidence results. The Azure Cognitive Service for Language returns confidence scores between 0 and 1 for each sentiment label, and the developer can set a minimum threshold (e.g., 0.75) to ensure only high-confidence predictions are used. This approach does not require retraining the model or modifying the input text, as the threshold is applied post-inference in the client code.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the Text Analytics for Health API instead.
Why it's wrong here
That API is for healthcare entities, not sentiment.
- ✗
Retrain the sentiment analysis model with additional labeled data.
Why it's wrong here
Sentiment analysis is prebuilt and cannot be retrained.
- ✓
Configure a minimum confidence threshold of 0.75 in the application logic.
Why this is correct
This filters out low-confidence results.
- ✗
Adjust the input text by removing ambiguous phrases.
Why it's wrong here
This may alter the meaning and is not a standard practice.
