Which service uses natural language processing to extract insights from text?

Amazon Comprehend is the service designed specifically to leverage natural language processing (NLP) to extract insights from unstructured text. It helps in identifying key phrases, entities, sentiment, and language from the text, enabling businesses to derive meaningful information and patterns from the vast amount of text data they handle.

The focus of Amazon Comprehend lies in understanding and interpreting human language, which includes functionalities such as sentiment analysis, entity recognition, and topic modeling. This makes it a powerful tool for tasks that involve understanding large volumes of textual information and utilizing it for decision-making processes and analytics.

In contrast, other services like Amazon Rekognition are focused on image and video analysis, identifying objects, people, or activities within images rather than text. Amazon Polly is designed for text-to-speech conversion, transforming written text into spoken words, and does not delve into extracting insights from text. Meanwhile, Amazon S3 is a storage service for saving and retrieving data across the web, not involved in any kind of language processing.
