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?

A

Amazon Polly

B

Amazon Personalize

C

Amazon Comprehend

D

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
