Introducing AWS Textract: Amazon’s Data Extraction And Text Recognition Service

1. Introduction

AWS Textract is a Machine Learning service that translates various document types into customizable formats. For example, consider that we have physical copies of invoices from several firms and that we save all the pertinent information on excel/spreadsheets. Unfortunately, we usually rely on data entry operators to input them manually, which is inconvenient, time-consuming, and error-prone. However, using Textract, all we must do is upload our invoices, and it will return all of the text, forms, key-value pairs, and tables in a more structured format.

AWS Textract not only detects typed text but also handwritten text in documents. It makes information extraction more valuable, as handwritten material might be more difficult to extract than typed text in some circumstances.

2. Top Features

1. Robust and Normalized Data Capture: Text and tabular data may be extracted from various documents, including financial records, research reports, and medical notes, using Amazon Textract. These aren’t bespoke APIs, but they do learn from a huge quantity of data every day, making extracting unstructured and structured data from your document a lot easier.
2. Extraction of Key-Value Pairs: The extraction of key-value pairs has become a typical challenge in document processing, but it can be readily handled using Amazon Textract. We can use Textract to create key-value pair extraction pipelines that automate document processing from scanning to transferring data to excel sheets.
3. Bounding boxes: Bounding box coordinates are returned with all extracted data. Each item of identifiable data, such as a single word, line, or table, is included by the coordinates, which form a polygon frame. This aids in the auditing process, where a word or number appears in the source material. It also aids in guiding the user through document search systems that provide scans of original documents as a consequence of the search.
4. Table extraction: During extraction, Amazon Textract retains the composition of data contained in tables. It is helpful for documents that include many structured data, like medical records, which have column names in the top row of the table followed by rows of individual entries.
5. Creating an intelligent search index: Amazon Textract allows you to build text libraries from images and PDF files. Amazon Textract allows you to extract text into words and lines using intelligent text extraction for Natural Language Processing (NLP). If Amazon Textract document table analysis is enabled, it also arranges text by table cells. You may choose how text is categorized as input for NLP using Amazon Textract.
6. Confidence scores: When Amazon Textract extracts information from documents, it offers confidence scores for every word, phrase, or table it finds, allowing you to make an educated decision about the following actions you, the user, wish to take.

AWS Textract has introduced a new function that allows you to interpret handwritten scanned documents. Reading handwritten texts is far more complex than reading digitally produced ones. Textract’s NLP algorithms look at the many types of typefaces in digitally printed papers and match them to extract information from the page. It is no longer the case when evaluating handwritten materials. Each person writes in a distinct style that is influenced by external variables (e.g. stress, urgency or device used). Textract will attempt to match the fonts, but instead of generating a font type once for a digitally printed document, each letter or word must now be compared to a font type.

3. Benefits of using AWS Textract

• AWS Services are simple to set up. Integrating Textract with another AWS service is simple compared to other providers. Configuring an add-on, for example, may be used to store extracted document information in Amazon DynamoDB or S3.
• Amazon Textract follows the AWS shared responsibility model, including data protection policies and procedures. AWS is in charge of safeguarding the worldwide infrastructure that underpins all AWS services, so we don’t have to be concerned about our information being leaked or misused.

4. Challenges while using AWS Textract

• A single invoice may have numerous data fields, such as ID, Pay date, Transaction Data, etc. These are fields that are seen on almost all invoices. However, Textract fails miserably, when extracting a custom field from an invoice, such as a GST number or bank account information.
• AWS Textract does not make it easy to interact with multiple providers; for example, if we need to establish a pipeline with Moodle etc., it will be tough to locate suitable Textract plugins.
• Textract does not enable you to set table headers for table extraction jobs. As a result, searching for or finding a particular column or table in a document would be difficult.
• Textract sends any document it processes to the cloud, with a few areas supported. However, some businesses may be hesitant to move their papers to the cloud due to concerns about confidentiality or regulatory constraints. Unfortunately, AWS Textract does not support any on-premise document processing deployments.
