Amazon Comprehend

 Amazon Comprehend is a natural language processing (NLP) service that uses machine learning to find insights and relationships in text. No machine learning experience required.

Amazon Comprehend now supports identification of text documents that contain personally identifiable information (PII). You can use Amazon Comprehend’s Contains PII API synchronously to discover documents that contain PII, to set up alarms and control access on documents with sensitive information. Amazon Comprehend’s machine learning models find documents that contain PII information such as social security numbers, credit card numbers, and email addresses and allow you to target the PII of your choice.

Amazon Comprehend provides pre-trained models for recognizing entities, key phrases, sentiments, and other common elements in a document. You can also build custom models with Amazon Comprehend to recognize custom entities and classify documents.
