Microsoft Azure AI Fundamentals — Question 162

You are developing a solution that uses the Language service.

You need to identify the main talking points in a collection of documents.

Which type of natural language processing should you use?

Answer options

• A. language detection
• B. sentiment analysis
• C. entity recognition
• D. key phrase extraction

Correct answer: D

Explanation

The correct answer is D, key phrase extraction, because it specifically focuses on identifying the main themes or topics in a text. Options A (language detection), B (sentiment analysis), and C (entity recognition) serve different purposes, such as identifying the language used, understanding the emotional tone, or recognizing named entities, respectively, which do not directly address the need to find main talking points.
