How Do You Make High Volume PDFs Accessible?

Digital Reports concept.

Insurance, finance, and many other organizations produce hundreds, thousands or even millions of PDF files in the form of customer statements, reports, minutes, directories and other scheduled informational documents. All of these documents are subject to digital accessibility compliance.  Insurance and other companies who receive federal funding of any kind must comply with Section 508. Other organizations must comply with the ADA, which the Department of Justice (DOJ) has asserted applies to “all the goods, services, privileges, or activities offered by public accommodations, including those offered on the web.” All digital accessibility laws include PDFs.

If your organization produces high-volume, system-generated PDFs by the thousands (or more), individually making each and every document accessible to people with disabilities would be impossible. Many companies choose to outsource this process, sending sensitive company information overseas and leaving the quality of the remediation work up to an outside company. Automation allows companies to keep the process in-house.

Keep accessibility in-house

By automating the high-volume PDF accessibility process, organizations can keep accessibility in-house, allowing them to easily control the timelines, costs, and quality.

Equidox AI is a completely automated process that is tailor-made to apply the correct accessibility tags to every document in the batch, no matter how many there are. Once deployed, it allows organizations to remediate entire batches of documents, which may include thousands of pages, at the click of a button with no other human intervention.

Which documents might need High Volume Solutions?

A wide variety of regularly generated documents would benefit from time-saving automated batch processing for remediation. 

  • For healthcare and insurance: explanations of benefits, claim summaries, statements, billing, reports, or provider directories.  
  • For government:  utility reports and billing, tax documents, budget reports, regulations, legislation, and guidelines.   
  • For banks and financial institutions: statements, reports, customer data, billing, and account summaries. 
  • For other businesses: financial reports, utility statements and billing, HR data, meeting minutes, product catalogs, inventory, safety reviews and more. 

Artificial intelligence and machine learning

Using artificial intelligence, specifically machine learning, computers can be trained to recognize similarities in document elements.  Every document can be broken down into its various components. By defining placement, formatting, and text, it is possible to automatically convert inaccessible content into accessible content.  Once these elements are defined, the Equidox machine-learning engine assigns the correct element tag for each piece of a report, statement, or other document. Equidox AI remediates all documents to meet 508 and WCAG compliance standards with 99.9% accuracy.  


How it works

Artificial intelligence developers program a machine learning engine to recognize specific elements within a document that are repetitive and/or identical. Each element is defined so that they are all tagged correctly through batch processing. 

The engine is programmed to know that a specific heading (like the title) is in the same place on every report generated by an organization.

Specific fonts or text formatting are defined as heading level 2.

Images are identified anywhere in the document and tagged as images and provided with correct alt-text descriptions.

Tables that appear in every report (such as those found in bank statements) are defined with table row and column headings.  All these definitions are set so that the content is tagged correctly as an accessible format.

Equidox AI does batch processing

Equidox data scientists train Equidox AI for your organization’s specific documents. The solution is built for large quantities of system-generated or regularly produced documents.  Remediation that would take many hundreds of hours using other methods can be automated using Equidox AI.
