Natural Language Processing with AWS AI Services

By: Mona M, Premkumar Rangarajan

Overview of this book

Natural language processing (NLP) uses machine learning to extract information from unstructured data. This book will help you to move quickly from business questions to high-performance models in production. To start with, you'll understand the importance of NLP in today’s business applications and learn the features of Amazon Comprehend and Amazon Textract to build NLP models using Python and Jupyter Notebooks. The book then shows you how to integrate AI in applications for accelerating business outcomes with just a few lines of code. Throughout the book, you'll cover use cases such as smart text search, setting up compliance and controls when processing confidential documents, real-time text analytics, and much more to understand various NLP scenarios. You'll deploy and monitor scalable NLP models in production for real-time and batch requirements. As you advance, you'll explore strategies for including humans in the loop for different purposes in a document processing workflow. Moreover, you'll learn best practices for auto-scaling your NLP inference for enterprise traffic. Whether you're new to ML or an experienced practitioner, by the end of this NLP book, you'll have the confidence to use AWS AI services to build powerful NLP applications.

Seeing the benefits of using Amazon A2I for HITL workflows

Amazon A2I is a managed service that makes it easy to build and manage human reviews with any ML application. It integrates directly with Amazon Textract and Amazon Rekognition to set up human workflows for use cases such as content moderation or document processing. You can also create custom workflows with any Sagemaker model. Some of the benefits of using Amazon A2I are as follows:

  • It comes with 70+ UI templates to get started quickly with setting up UIs for human reviews. Check them out here: https://github.com/aws-samples/amazon-a2i-sample-task-uis.
  • It reduces the time to market for your AI systems, as you know that there is a human backstop to catch low confidence scores.
  • It provides you with options to choose a workforce. By workforce, we mean who is going to review the human loop tasks created. There are three choices with A2I – a private workforce, Amazon Mechanical Turk, and third-party vendors...
