Project Level Fields
You can define fields at the project level, for which extraction is performed at the
beginning of classification. The extraction results of these fields may be used for the
classification of a document. For example, this makes it easy to classify a document
according to a barcode or to perform a language dependent classification using a
classification locator. When doing this, the locator result is saved to a project level
field.
Classification
A project consists of a class hierarchy in which each class is assigned a set of
classifiers and the data to be extracted during processing is defined. The classes
represent different types of documents. Each class of documents is treated differently
during the extraction of information, but all documents of a certain class are handled
identically.
Note
By definition, an invoice project has only a single class (the invoice class) and
one sub class, so there is no class tree displayed in the application interface.
The classifiers decide to which class a document belongs. There are two types of
classifiers:
• Image classifiers identify documents based on a graphical representation of
the image.
• Content classifiers identify documents based on their textual content, and
require the results from an Optical Character Recognition (OCR) engine.
