Introduction
This chapter introduces the components included with Kofax Transformation Modules, as
well as their key features.
Kofax Transformation Modules
Kofax Transformation Modules provides additional automatic classification, separation,
and extraction, as well as advanced user interactive functionality such as, indexing and
validation to Kofax Capture.
Kofax Capture scans paper-based documents, creating a series of scanned image files. Alternatively, Kofax Capture Import Connector - Email can retrieve emails (including attachments) from a server. Kofax Capture then routes the files through Kofax Transformation Modules, which separates pages into documents, classifies documents and extracts
information. Within Kofax Transformation Modules these classification, separation and
extraction results are presented for review by users. After all documents have been validated in the attended modules, the batch is analyzed to increase the recognition of documents with the same layout by an “online learning” algorithm. Finally, the accurate, validated data and images are exported to a back-end system using Kofax Capture.
Chapter 1
Overview
Kofax Transformation Modules consists of a set of components, either Kofax Capture
custom modules or additional tools. In this documentation, the components are also referred to by their module or tool name, omitting the product name as a prefix.
Module Order
The following diagram shows Kofax Capture as the platform for the Kofax Transformation Modules components, linking them together into the complete solution. The configuration tools are used to tailor the modules for the particular documents being processed.

the Recognition Server module in the Kofax Capture workflow. Documents are classified
and processed for data extraction and then routed to the attended modules, Knowledge
Base Learning Server and/or the Release module.
A Typical Kofax Transformation Solution
A typical Kofax Transformation solution will have multiple dedicated stations for each
module. For example, there may be a scanner station, stations automatically running
Server and Knowledge Base Learning Server, computers dedicated to running the Document Review module, several more computers running Correction, Validation, and Verification, and a Release station, as shown in the following illustration. Depending on the
documents being processed and the requirements of the system, some modules in the Kofax Transformation Modules may not be used.

How Do I Use Document Review?
Introduction
The purpose of Document Review is to ensure that every document in a batch contains
the correct pages and has the correct classification. Operators are presented with a list of
problems that need to be fixed before a set of documents can be processed further.
Kofax Capture Workflow
A batch is processed through Kofax Capture and is classified, separated, and optionally extracted by the time it reaches Document Review. If there are any problems with the
classification and separation, they can be solved in Document Review.
After a batch has passed through Document Review, it will be sent for further extraction
for any document with an altered structure. The data extracted at this stage of the workflow is critical, so it is important that any problems are fixed in Document Review beforehand.
After extraction is complete, the batch is passed on to additional modules to further process the extracted information. Finally, each document along with its extracted information is released to a back-end system for storage or further processing.
Problems in Document Review
The solution integrator decides which Document Review rules will be applied when a
Kofax Transformation solution is configured. If any of these rules are not met when a
batch is run, they appear as problems to be fixed in Document Review.
A problem consists of one or more failed Document Review rules that appear on a document or at the global level in the batch. This means that a batch may have several problems, each with one or more rule failures.
Kofax Transformation Modules User's Guide
19
Chapter 2
For example, a project has been configured requiring that a batch contain at least 50 documents, ten of which are application forms. These requirements are configured using
two separate rules: one rule to specify the minimum number of documents needed in the
batch, and a second rule to specify that there need to be at least ten applications in the
batch.
After the batch is processed, there are only nine application forms and 49 documents due
to poor separation. When Document Review starts, there is a single problem at the batch
level that lists both of the Document Review rule failures as specified above.
Processing Batches with Document Review
You can start Document Review manually like a standard Windows application or from
the Kofax Capture Batch Manager module. If you use the Batch Manager module, Document Review opens the batch and automatically shuts down when the batch is closed or
suspended.
Document Review can be configured to open the next batch automatically. In this case,
after starting the module or closing the current batch, any waiting batch opens automatically.
20
Note If no batches are waiting a message “No waiting batches” is displayed instead.
To configure the option to open batches automatically
➤
From the Options menu, select Settings.
1
Select Open next batch automatically.
2
If required, select Poll for next batch (seconds) and type a value in the box.
3
If required, select Include suspended batches.
4
If the Open next batch automatically option is cleared, different behavior occurs when
starting the module or closing the current batch. The Open Batch window is displayed, allowing you to choose a waiting batch.
To open a batch
➤
In the Open Batch window, select a batch from the list.

Important If a batch contains folders, several batch editing options are not available in
Document Review.
Reviewing Documents
Document Review is a comprehensive interface that allows you to fix problems using the
following features:
■
Batch Content Panel provides a clear structure of the batch, including thumbnail
images of pages.
■
A panel provides details of the current problem, particularly the Document Review
Rules which has not been met.
■
The first page of the selected document is displayed in the Document Viewer. You
can display others by using simple navigation.
Fixing Problems
A problem is displayed in Document Review if any of the following batch rules are not
met:
■
This batch must have N documents.
■
This batch must have N documents of class X.
Document Review identifies problems if any of the following document level rules are
not met:
■
Every document of this class must have N pages.
■
Every document must have a class.
■
Every document with a suggested class must be reviewed.
This Batch Must Have N Documents
This batch has an incorrect number of documents. You can resolve this problem by performing one of the following actions:

Drag and Drop
If a document contains a page that belongs to a previous or subsequent document, you
can drag this page to the correct document. Similarly, if the pages within a document are
in the incorrect order, you can drag and drop the pages to reorder the document.
To move a page, select the page you want to move and use your mouse to drag-and-drop
the page to the desired location.
Merging Documents
If a document has been incorrectly separated, you can merge it with the previous document to make a complete document.
In order to merge a document, you need to select the document that was incorrectly separated from its previous document. From the Document menu, select Merge to Previous
to combine the selected document with the previous document listed in the Batch Content
panel.
