Intelligent Document Processing

Introduction

Up to this point, companies that needed to extract data from documents and forms had two options: slow, labor-intensive manual entry or outdated, hard-to-customize optical character recognition software.

But if you have Appian, you have another option: intelligent document processing (IDP) capabilities. With IDP, you can automate some of your most common tasks when it comes to documents your business receives. IDP is no longer a single application for document classification and extraction. Instead, IDP is a suite of capabilities within Appian that allow you to automate the most labor-intensive parts of document management.

What's possible? We're glad you asked. With Appian, you can:

Implementation patterns

Extract data from tables across multiple pages

To extract data from tables that span multiple pages in a document:

  1. Use the PDF Tools plug-in to split the document into individual pages.
  2. Use the document extraction AI skill to extract table data from each page.
  3. Combine the results using post-processing logic.

Merge documents

When documents are received in packets containing multiple document types:

  1. Split the file into individual pages.
  2. Classify each page into its appropriate document type using the document classification AI skill.
  3. Combine like pages into new files.
  4. Send the newly composed files to the document extraction AI skill created for the corresponding document type.

Split documents

When documents are received in packets containing multiple document types:

  1. Split the file into individual pages.
  2. Classify each page into its appropriate document type using the document classification AI skill.
  3. Send the split files to the document extraction AI skill created for the corresponding document type.

Implement capture rules

  1. Add the Extract from Document smart service to a process.
  2. Configure the Confidence Threshold input and Confidence Score output according to your requirements.
  3. Configure additional verification using expression rules or user input tasks to confirm documents near the confidence threshold meet your requirements.

Validate documents

  1. Extract data from the documents using the document extraction AI skill and Extract from Document smart service.
  2. To verify the completeness or accuracy of required fields, use expression rules or user input tasks.
