Overview
Ascent Xtrata Pro User's Guide 15
Ascent Xtrata Pro is designed to read semi-structured invoices. Therefore every
project has a set of predefined fields for the most common items found on all types of
invoices. These fields are almost always logically arranged on the invoice, and each
field has one of the group locators assigned to it.
Each group locator takes advantage of existing knowledge about the geometry of
these groups, and uses that knowledge to improve data extraction.
This means that you should train all fields you care about by setting up a training set
with sample documents, or use an existing knowledge base. To improve the quality
of recognition it is recommended to train all fields for a group locator that are
available on the document even if you do not need, like for example postage and
packaging.

Group Locator, and Extraction – Order Group Locator.
