When would you use Amazon Comprehend?

Amazon Comprehend is a natural language processing (NLP) service that allows users to analyze and gain insights from text. It is designed to identify sentiments, key phrases, entities, language, and more within the text data. By selecting this option, it highlights the service's primary purpose, which is to provide advanced text analytics. This understanding enables users to extract meaningful information from large volumes of unstructured text, contributing to better decision-making and understanding of customer feedback, social media content, and other textual data sources.

In contrast, the other options represent functions or services that are outside the capabilities of Amazon Comprehend. Video analysis typically involves different methodologies and tools that focus on visual data rather than textual. Storing and managing large datasets is more aligned with services like Amazon S3 or Amazon RDS, which focus on data storage rather than analysis. Developing deep learning frameworks usually pertains to services like Amazon SageMaker, which are specifically designed for building and training machine learning models rather than analyzing text data.
