What is Amazon Comprehend and what kinds of insights can it extract from text?

Answer

Amazon Comprehend is a natural language processing service that uses machine learning to extract insights from text, including identifying the overall sentiment of a piece of text, recognizing key phrases and named entities such as people or organizations, detecting the dominant language, and even identifying custom entities or classifications specific to your own business when trained with your own labeled examples.
