Microsoft Azure AI Fundamentals — Question 133

You have a solution that analyzes social media posts to extract the mentions of city names and the city names discussed most frequently.

Which type of natural language processing (NLP) workload does the solution use?

Answer options

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

Correct answer: D

Explanation

The correct answer is D, entity recognition, as it specifically focuses on identifying and classifying named entities, such as city names, in text. The other options, like speech recognition and sentiment analysis, do not pertain to the extraction of specific entities, while key phrase extraction is more about identifying phrases rather than specific named entities.
