Explanation:
Amazon Comprehend is AWS's natural language processing (NLP) service that uses machine learning to find insights and relationships in text. It can analyze text to extract key phrases, entities, sentiment, and language. While other services like Amazon Lex (for chatbots), Amazon Rekognition (for computer vision), and Amazon Translate (for language translation) are related to AI/ML, Amazon Comprehend is specifically designed for natural language understanding and processing tasks.
