Which task can Amazon Comprehend NOT perform?

Amazon Comprehend is a natural language processing (NLP) service that specializes in analyzing and understanding text. It provides capabilities such as sentiment analysis, entity recognition, and keyphrase extraction, all of which pertain to processing and deriving insights from written language.

Sentiment analysis allows it to assess the emotional tone behind a series of words, helping determine whether a piece of text is positive, negative, or neutral. Entity recognition involves identifying and classifying key elements in the text, such as names of people, organizations, locations, and other relevant information. Keyphrase extraction enables the service to pull out significant phrases that capture the essence of the text.

In contrast, image recognition is outside the scope of Amazon Comprehend's functionality. This task typically involves analyzing visual data—such as photographs or videos—to identify objects, scenes, or other features. Services like Amazon Rekognition are specifically designed for image and video analysis, making them suitable for tasks related to visual content, while Amazon Comprehend is dedicated solely to text analysis. Therefore, the ability to perform image recognition is not a feature of Amazon Comprehend.
