AI-102 Practice Question: Implement natural language processing solutions
A company wants to analyze customer reviews to determine whether sentiment is positive, negative, or neutral. The solution must also extract key phrases such as 'great battery life' and 'poor camera quality'. Which Azure AI feature should be used?
⚠ Common exam trap
Many exam-takers confuse Named Entity Recognition (NER) with key phrase extraction because both extract text, but NER targets predefined entity types (e.g., person, location) while key phrase extraction targets descriptive phrases that are not entities.

Azure AI Language - Sentiment Analysis and Key Phrase Extraction
Azure AI Language's Sentiment Analysis and Key Phrase Extraction are specifically designed to evaluate text for positive, negative, or neutral sentiment and to extract meaningful phrases like 'great battery life' or 'poor camera quality'. This combined capability directly matches the dual requirement of sentiment classification and key phrase extraction in a single API call, using pre-built models that require no custom training.
