Question #832
An online bookstore wants to recommend books to customers based on their purchase history and browsing behavior. Which AWS service should they use?
Amazon Polly
Amazon Personalize
Amazon Comprehend
Amazon Rekognition
Explanation
Amazon Personalize is tailored for building recommendation systems using machine learning. It analyzes user interaction data (e.g., purchases, browsing) to deliver personalized content.
- Why B is correct: Personalize trains models on user-specific data to generate recommendations, aligning with the bookstore's needs.
- Why others are incorrect:
- A (Polly): A text-to-speech service, unrelated to recommendations.
- C (Comprehend): An NLP service for text analysis, not user behavior modeling.
- D (Rekognition): An image/video analysis tool, irrelevant to recommendation engines.
Key Points:
- Use Personalize for ML-driven recommendations based on user activity.
- Other services address speech, text analysis, or image processing, not recommendation systems.
Answer
The correct answer is: B
