Setting Up Extraction
The following section describes the general steps for setting up extraction. For details
about fields and locators, see Extraction.
Adding Fields and Locators
You can define fields at the project level, for which extraction is performed at the
beginning of classification. The extraction results for these fields may be used to
classify a document. For example, you can classify a document based on a barcode,
or you can perform a language dependent classification using a classification locator,
where the locator's result is saved to a field at the project level.
In addition, you can define fields for each class which are then inherited by any
derived classes. For a derived class, you can either use the definitions inherited from
the base class or change the extraction methods for the fields.
X To set up extraction
1
Select a class from the Project panel.
2 Change to the Extraction Design mode by selecting View | Show Extraction
Design from the main menu. The Extraction Design panel shows fields and
locators defined for the class. Note that derived classes inherit fields from all
their parent classes.

a
Click Add Field from the Fields toolbar (in the Extraction Design panel)
and enter a name for the field.

Select the type for the field (simple or table) by right-clicking the field
and selecting Field Type from the context menu. The default type is
“Simple Field.”

Select the desired properties for the field by right-clicking the field and
selecting Field Properties.
For more details about fields, see Extraction.
