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.

Introducing the PDF batch processing use case

To determine what the architecture will look like, you talk to your accounting department to understand the process for registering companies with the SEC. As per the process, the accounting department will generate PDF documents using the SEC's template for registration, also known as Form S20 (https://www.sec.gov/files/forms-20.pdf). The process also involves creating all the supporting documentation, along with the registration, which will be sent together to the SEC using an API call. LiveRight's Partner Integration team has the handshake with SEC in place, and they need the form data to be available in an Amazon DynamoDB (https://aws.amazon.com/dynamodb/) table that they will consume to create the message call to the SEC API.

However, before making the data available to the Partner Integration team, the accounting team mentioned that they need to review a collection of text lines that have been detected in the PDF document...
