Identification and Multiple Document Classes

If you have the Document Classification add-on installed, you will be able to configure multiple document classes within a single Quick Fields session. With multiple document classes, the order of the classes and the identification criteria within each can interact to produce very different results. Identification works by comparing each scanned page to the identification conditions for each document class. With multiple document classes, Quick Fields will proceed as follows:

• Compare each scanned page to identification criteria for the first document class.
• If the page matches the criteria for the first class, it will be assigned to that class and will not be compared to the criteria for any other classes.
• If the page is not assigned to the first class, it will be compared to the identification criteria for the next class. It will either be assigned to that class or proceed to the next class.
• If the page does not meet the identification criteria for any of the document classes, with the default Quick Fields settings it will be appended to the document that was created the last time a page did meet an identification condition. If you have changed the Document Length settings, it may be appended if it is within the specified number of pages, or may be sent to Unidentified Documents.

Therefore, a document that fits the identification criteria for more than one document class will only be assigned to the first class whose identification criteria it meets. For this reason, the order of document classes in the Session Configuration Pane is very important.

To change the order of document classes

1. Select the Classification node in the Session Configuration Pane.
2. In the Tasks Pane, under Reorder Document Classes, select a document class.
3. Use the arrows to move the document class up and down in the order.

Note: You can also use Pre-Classification Processing and Token Identification to improve the efficiency of Identification. This is particularly helpful with multiple document classes.
