Overview of this book

Are you fascinated with applications like Alexa and Siri and how they accurately process information within seconds before returning accurate results? Are you looking for a practical guide that will teach you how to build intelligent applications that can revolutionize the world of artificial intelligence? The Applied AI and NLP Workshop will take you on a practical journey where you will learn how to build artificial intelligence (AI) and natural language processing (NLP) applications with Amazon Web services (AWS). Starting with an introduction to AI and machine learning, this book will explain how Amazon S3, or Amazon Simple Storage Service, works. You’ll then integrate AI with AWS to build serverless services and use Amazon’s NLP service Comprehend to perform text analysis on a document. As you advance, the book will help you get to grips with topic modeling to extract and analyze common themes on a set of documents with unknown topics. You’ll also work with Amazon Lex to create and customize a chatbot for task automation and use Amazon Rekognition for detecting objects, scenes, and text in images. By the end of The Applied AI and NLP Workshop, you’ll be equipped with the knowledge and skills needed to build scalable intelligent applications with AWS.

Another interesting NLP Amazon service is Textract. Essentially, Textract can extract information from documents, usually business documents such as tax forms, legal documents, medical forms, bank forms, patent registrations, and so forth. It is an optical character recognition (OCR) solution for scanning structured documents, suitable for robotic process automation (RPA). Textract is a relatively new service—previewed in November 2018 and generally available in May 2019.

The advantage of Textract is that it understands documents and can extract tables and/or key-value pairs suitable for downstream processing. A lot of business processes, such as health insurance processing, tax preparation, loan application processing, monitoring and evaluation of existing loans, compliance evaluation, and engineering evaluations take in these documents, usually processing them manually to extract information and then start digital processes. Using Amazon Textract, the manual...
