AI-102 Practice Question: Implement natural language processing solutions
Your company uses Azure AI Language to analyze customer feedback. You need to extract key phrases from reviews in multiple languages. Which feature should you use?
⚠ Common exam trap
Test-takers frequently confuse key phrase extraction with named entity recognition, assuming that extracting important names or places is the same as extracting key topics, but NER focuses on specific entity types while key phrase extraction captures broader, contextually important phrases.

Correct answer & explanation
✓
Key phrase extraction
Key phrase extraction is the correct feature because it is specifically designed to identify and extract the most important points or topics from text, regardless of the language. Azure AI Language's key phrase extraction supports multiple languages and returns a list of key phrases that represent the main subjects discussed in the customer feedback, which directly meets the requirement.
