Explanation:
Amazon Comprehend is the correct AWS service for sentiment analysis. It is a natural language processing (NLP) service that uses machine learning to find insights and relationships in text, including sentiment detection (positive, negative, neutral, or mixed).
Why other options are incorrect:
-
Amazon Rekognition: This service is for image and video analysis, not text sentiment analysis.
-
Amazon Transcribe: This service converts speech to text, but doesn't analyze sentiment in the transcribed text.
-
Amazon Translate: This service translates text between languages, but doesn't perform sentiment analysis.
Key Features of Amazon Comprehend:
-
