The Document Classification Supervision task is the first step in Supervision. It is used to categorize and combine pages that were not classified by the machine.

To enable Document Classification, select the Manual Classification Supervision setting in your flow. To learn more about flow settings, see Flow Settings.

Document Classification task

Document Classification allows you to provide additional structure to submissions as part of the Page Sorting phase of processing.

Specifically, Document Classification allows a user to do the following:

Add uncategorized pages to grouped documents.
Reorder pages in grouped documents.
Remove pages from grouped documents.
Classify (apply layouts to) manually grouped documents.
Reclassify (apply different layouts to) machine-misclassified documents.

This task supports the customer workflows that require the association of documents within a submission for downstream processing. For example, if a particular Semi-structured form must be accompanied by additional materials (e.g., a paystub or check) in order to be considered valid, Document Classification allows you to associate the form with its additional materials in the submission and reflect this association in the submission output.

Document Classification task’s interface

The Document Classification task’s interface includes a page that contains three vertical panels - left, middle, and right panel.

Left (uncategorized) panel

The left panel contains all uncategorized pages. To provide additional context for the keyer, the pages are displayed in the order in which they were submitted. A thumbnail of each uncategorized page is shown in the left panel, and a larger view of the page in focus is shown in the preview panel on the right.

Selecting pages from the left panel, using either the mouse or keyboard shortcuts, allows you to add these pages to a new or existing document in the middle panel.

To submit the Document Classification task, all pages from the left panel must be categorized. If some pages do not have a matching layout available, you can select the “Other” category for them from the layout drop-down list. Selecting “Other” as a layout variation for these pages results in sending them to the No Layout Variation Found section ( Submissions > No Layout Variation Found).

Middle (grouped documents) panel

The middle panel contains all grouped documents in a submission. In this panel, you can add, remove, and reorder pages in grouped documents.

All pages in the left and middle panels have submission page numbers assigned to them. These numbers represent the order in which these pages were submitted into the system.

Grouped documents in the middle panel are ordered by the submission page number of the first page in each document. When you manually create a new document in the middle panel, its pages are automatically reordered by submission page number, and no layout is selected. You need to manually select a layout.

Right (preview) panel

The right panel shows a zoomable full-page view of your selected page.

Completing Document Classification task

The following options are available to you during Document Classification tasks.

Grouping pages into documents

During Document Classification, you can group multiple pages into documents. For example, several pages that are part of a single invoice can be categorized as invoice pages and combined into a single multi-page invoice document.

For all pages in the left panel, you need to:

click the Create New button at the bottom of the panel to create new documents for these pages, or
use drag-and-drop or keyboard shortcuts to move these pages to existing documents in the middle panel.

For each grouped document in the middle panel, you need to select a layout variation. The options include all live layouts for the given release, as well as "Blank Page," "Additional Form Page," and "Other."

Adding and removing pages from documents

In the sections below, you can learn about reclassification of Structured and Semi-structured documents.

Adding and removing pages from Structured documents

Reclassification of Structured documents relates to:

reclassifying (applying different layouts to) machine-misclassified Structured documents,
adding pages to machine-classified Structured documents with missing pages, and
removing pages from machine-classified Structured documents.

Adding and removing pages from Semi-structured documents

Reclassification of Semi-structured documents relates to adding and removing pages from machine-classified Semi-structured documents.

Manual Rotation

Sometimes the sampled documents may go to Manual Classification with an incorrect orientation. Learn more in Manual Rotation.

Reprocessing of misclassified documents

When initiated from other Supervision tasks, the Document Classification task allows users to manually classify machine-misclassified documents. As a result, the users can reclassify all pages of the submission and submit them for reprocessing.
