Microsoft Azure AI Fundamentals — Question 79

You have a webchat bot that provides responses from a QnA Maker knowledge base.
You need to ensure that the bot uses user feedback to improve the relevance of the responses over time.
What should you use?

Answer options

• A. key phrase extraction
• B. sentiment analysis
• C. business logic
• D. active learning

Correct answer: D

Explanation

Active learning is a machine learning approach that involves using user feedback to refine and improve the model's performance, making it the best choice for enhancing response relevance. Key phrase extraction, sentiment analysis, and business logic do not directly utilize user feedback to iteratively improve the response quality.
