Presenting Amazon Textract's product features

Alright, it's time to start exploring the cool features we have been talking about so far. We will start by seeing how you can quickly upload the sample documents provided in our GitHub repository (https://github.com/PacktPublishing/Natural-Language-Processing-with-AWS-AI-Services) to your Amazon Textract AWS console. Then, we will walk through the key features of Amazon Textract, along with multi-language support by using a French COVID-19 form. We will also cover Amazon Textract's integration with Amazon A2I, which will quickly help set up a human review workflow for the text, which needs to be highly accurate, such as an invoice amount (https://aws.amazon.com/augmented-ai/) at a high level. We will cover the following:

  1. Sign in to your AWS Management Console.
  2. Upload sample document(s).
  3. Raw text or text extraction.
  4. Key value extraction or form values.
  5. Table extraction.
  6. Multiple language support...
