ABBYY Recognition Server will supplement scanning devices and backend software used in the organization with powerful document capture functionality. Integration with a scanner or another application can be done in various ways, from exchanging e-mails to scripted routing and tight bonding via API.

• Offers ready-made connectors to Microsoft and Google Search systems

ABBYY Recognition Server not only acts as a standalone document capture solution, but also connects as a background OCR server to the enterprise search systems such as Google Search Appliance™ and Microsoft Office SharePoint® Server, as well as Windows® Desktop Search enabling the aforementioned systems with the ability to index and search through the content of image documents.

ABBYY Recognition Server 3.5 System Administrator’s Guide

Architecture

Main Components

ABBYY Recognition Server consists of 8 main components: Server Manager, Scanning Station, Processing Station, Verification Station, Indexing Station, Remote Administration Console, COM-based API, and Web Service.

Server Manager

This is the main component. It works as a Windows service, manages licenses and all processing options, forms and manages the job queue, distributes the jobs among Processing Stations, Verification Stations, and Indexing Stations, and delivers the output documents after processing. It also coordinates the work of other components (Processing Stations, Verification Stations, and Indexing Stations) and interacts with the Remote Administration Console and the Open API. The Server Manager does not perform recognition, this task is performed by Processing Stations.

ABBYY Recognition Server will not function without the Server Manager. To run the Server Manager, you need an activated and non-expired license. See the Protection Technology and License Activation section for details.

Scanning Station

This component allows you to perform batch scanning and pass images to Recognition Server for further processing.

Processing Station

This component is a Windows service that directly performs recognition. It processes files received from the Server Manager.

The Recognition Server allows you to connect several Processing Stations to one Server Manager in order to increase the processing speed and maximize the throughput. The Server Manager will evenly distribute the workload among the CPUs of the Processing Stations.

ABBYY Recognition Server 3.5 System Administrator’s Guide

Verification Station

This is a client station which allows you to proofread the recognition results. The Verification Station automatically receives the recognized pages that must be verified from the Server Manager. You can connect several Verification Stations to one Server Manager to speed up the verification process.

Indexing Station

This is a client station which allows you to assign a document type and meaningful attributes to recognized documents, so that they can be easily classified and found later in archives and document management systems. The Indexing Station automatically receives the recognized documents that must be indexed from the Server Manager. You can connect several Indexing Stations to one Server Manager to speed up the indexing process.

Remote Administration Console

This is a Microsoft® Management Console (MMC) snap-in that provides a common administration interface for configuration and monitoring Recognition Server.

COM-based API

This API allows you to integrate Recognition Server with other applications in the local area network. The COM-based API component should be installed on the computer on which the client application will run. It can also be distributed together with the client application. See more information about the distribution of the COM-based API in the Open API Help file.

Web Service

This component provides a Web Service API for integrating the Recognition Server with remote applications over the HTTP protocol.

All the Recognition Server components can be installed on the same or on different computers in the local area network.

Additional components

ABBYY Recognition Server includes 2 additional components: the Google Search Appliance Connector and Microsoft Search IFilter, — these allow the Server Manager to interact with Google and Microsoft search systems. Image files the contents of which cannot be indexed directly are sent to ABBYY Recognition Server for OCR. The recognized text data is returned to the search server and included in the full-text index.

Google Search Appliance Connector

This component allows interacting with the Google Search Appliance system.

Microsoft Search IFilter

This component allows interacting with Microsoft Search Server, Microsoft Office SharePoint Server and Microsoft Windows Search.

Workflows, Jobs, and Documents

ABBYY Recognition Server operates with three basic entities: workflows, jobs, and documents.

A workflow is a set of processing parameters that are to be applied to image files. Recognition Server can handle several workflows with different parameters. Each workflow corresponds to a unique input source (a folder or a mailbox). All the images that appear in the source folder/mailbox are processed using the parameters of the corresponding workflow. See Creating a New Workflow.

ABBYY Recognition Server allows setting a schedule and a priority for the workflow. For example, a workflow for old documents can be given the low priority and scheduled to run only at night and on weekends, while a workflow for urgently-required documents will be given the high priority and set to run constantly. A schedule is set in the Input tab of the Workflow Properties dialog of the Remote Administration Console. See also Creating a Schedule in the Main Help.

ABBYY Recognition Server 3.5 System Administrator’s Guide

A job is a processing unit. A job contains an image (or a set of images) and its processing parameters. A job is created when Recognition Server imports images for processing. Usually a job contains one image file and inherits the processing parameters of the workflow in which it was created. However, with the help of the Open API or XML Tickets it is possible to create a job that will contain several image files and will have parameters different from the workflow settings.

A document is obtained as a result of document separation and usually corresponds to one business document. Below are examples of how the documents are formed in case of document separation:

By default, all files of the job are merged into one document. One document can be published in several different file formats according to the export settings.

Document Workflow

The following processing steps are performed since the images are submitted to ABBYY Recognition Server 3.5 till they are exported:

1. Import

2. Processing

3. Document separation

4. Quality control (optional)

5. Indexing (optional)

6. Export

ABBYY Recognition Server 3.5 System Administrator’s Guide

Import

On this stage images are placed to the Input folder of the workflow. There are several ways to pass document images for processing. The images can be manually placed to the Input folder, automatically passed from the Scanning Station, or sent by e-mail.

When image documents get in the Input folder or mailbox, they are imported by the Server Manager and transferred to the Images subfolder of the ABBYY Recognition Server 3.5 temporary folder. The path to the Server Manager temporary folder can be viewed and changed in the Recognition Server Properties Dialog Box of the Remote Administration Console.

The image files are kept in the Images subfolder of the Server Manager temporary folder throughout the entire conversion process. The Processing Stations, Verification Stations, and Indexing Stations receive copies of those images for processing. This ensures that no files are lost in case an error occurs during the recognition, verification, or indexing.

When image files are submitted to ABBYY Recognition Server 3.5, the Server Manger creates jobs for them and queues them for processing. If several workflows are set up, ABBYY Recognition Server will process jobs from all the workflows simultaneously, within the single queue. The jobs will be arranged in the queue according to their creation time and priorities.

Processing

The first job in the queue is sent to the first available Processing Station for recognition. If there are several Processing Stations in the system, the Server Manager evenly distributes the jobs from the queue among these Processing Stations. See Registering a New Processing Station.

A Processing Station can run several OCR processes (their number can be adjusted in the Remote Administration Console). For optimal performance, the recommended number of processes for a station is N+1, where N is the number of CPU cores on the station. Usually each OCR process gets one file at a time. For example, if a Processing Station runs two OCR processes, it will recognize two files in parallel (they can belong to the same job or to different jobs). However, if the file has many pages (e.g. several dozen) and there are no more than 5 jobs waiting in the queue, the big file will be split into several chunks, and the chunks will be sent to different OCR processes, in order to get the work done faster.

When the Processing Station has finished processing the file, it returns the recognized file to the Server Manager and is assigned the next job from the queue.

Document separation

After recognition, the pages in the job queue will be rearranged into documents according to the separation rule. Document separation is performed within a task. Depending on the source specified in the Import stage, different document separation methods are available. In addition to built-in document separation methods (by barcodes, blank pages, etc.) separation using a script can be performed. See Configuring Document Separation.

Verification

If verification is turned on in the workflow settings, documents that require verification will be queued for verification after recognition. If there are Verification Stations connected, the Server Manager will route the queued documents to those stations. If no Verification Stations are currently connected, or the users logged on the stations are not permitted to verify documents from this workflow, the documents will wait in the queue in the "Queued for verification" state. They will not be passed for further processing until they are verified. See Configuring Verification.

Indexing

If there are any document types specified in the workflow settings for indexing, documents from this workflow will be indexed before export. Indexing can be performed automatically with the help of a script or/and manually on an Indexing Station. Firstly indexing using a script is performed if a script is entered, then documents that require manual indexing are queued for indexing. If there are Indexing Stations connected, the Server Manager will route the queued files to those stations. If no Indexing Stations are currently connected, or the users logged on the stations are not permitted to index documents from this workflow, the document files will wait in the queue in the "Queued for indexing" state. The document will not be exported until it is indexed. See Configuring Document Indexing.

Export

When the recognition, verification, and indexing are completed, the output files are handed back to the Server Manager and queued for publishing. The Server Manager delivers the output document to the destination specified in the job settings. After the output file is published to the Output folder, the image copy is removed from the Server Manager temporary folder. Then published files can be sent to appropriate destination depending on input and output files

ABBYY Recognition Server 3.5 System Administrator’s Guide

properties, recognition statistics, etc., if a script for successfully published jobs is specified. If a script for failed jobs is entered, images that failed to be processed are delivered to the destination specified in the script.

Centralized Administration

ABBYY Recognition Server 3.5 is administrated via a separate component, the Remote Administration Console, which is based on the Microsoft Management Console (MMC). The Remote Administration Console allows administrators to change Recognition Server's properties, connect Processing Stations and manage their properties and activity, create and manage workflows, add users to the system and assign Administrator, Verifier, and Indexer permissions to the users, monitor connected Verification and Indexing Stations and the job queue, view and export the job log and the server log, and manage licenses.

If several ABBYY Recognition Servers are installed in the local area network, they can all be registered in the same Remote Administration Console and thus all managed from a single point. See Registering a New Recognition Server.

Scalability

One Server Manager can manage dozens of Processing Stations connected to it and effectively distribute the workload among them. This makes the whole system highly scalable to meet high-volume processing demands. By connecting multiple Processing Stations, you can increase the processing speed up to several hundred pages per minute.

Note: The picture shows the speed increase as measured in ABBYY's internal tests. System performance may vary depending on the complexity and quality of the images, the hardware of the server and the stations, and the network configuration.

Fault Tolerance

As ABBYY Recognition Server 3.5 runs completely unattended, it has a number of fault tolerance features that ensure robustness of the system:

• The system starts automatically at Windows startup. For example, in the case of a temporary power outage, ABBYY Recognition Server will be up and running automatically after the PC is rebooted.

• Documents are processed so that no data are lost in the case of a system failure. All the images that were being processed when the failure occurred will stay in the queue and will be processed again after the system is restarted.

• The Server Manager periodically checks to make sure that the Processing Stations are running and are available. If a Processing Station is temporarily down for some reason, the Server Manager will re-establish connection with it after it becomes operational. No administrator's involvement is required to re-connect a Processing Station.

• If a Processing, Verification, or Indexing Station experiences a failure while processing a document, the document will be automatically re-routed to another available station. If no station is available at the moment, the image will remain in the queue and wait for the first available station.

ABBYY Recognition Server 3.5 System Administrator’s Guide

Integration Tools

Scripts

ABBYY Recognition Server 3.5 provides an easy way of customizing the workflow and integrating with external systems with the help of scripts. The program allows you to use scripts for document separation, automatic document type detection and indexing, and postprocessing of published documents and their attributes. Document processing scripts are defined in the workflow settings and can use various parameters of documents, such as recognized text and its coordinates, image file properties and recognition statistics.

XML Tickets

ABBYY Recognition Server 3.5 provides a convenient way to customize job settings via so-called XML Tickets. An XML Ticket is an XML file that contains a set of processing parameters for the job. The parameters set in the XML Ticket override the workflow settings. If an XML Ticket accompanies one or several input files, these files will be processed using the parameters set in the ticket. XML Tickets can be used to define almost all job parameters, such as priority, recognition languages, output formats, output file name and path, etc.

XML Tickets can be created either manually (in a text editor) or programmatically, via the Open API.

XML Tickets can be used for integration of ABBYY Recognition Server with front-end systems and devices (for example, the processing options that the user sets on the scanner panel can be transferred to ABBYY Recognition Server in an XML Ticket).

Open API

ABBYY Recognition Server provides two types of Open API for integration with external systems: a COM-based API and a Web Services API. Both APIs provide the following functionality:

• submitting images for processing

• creating and submitting XML Tickets for processing

• getting notifications about the job completion and information about the job results

The COM-based API uses RPC technology and can be used for integration with other systems in the local area network.

The Web services API enables communication with remote systems via HTTP, and therefore allows for remote integration over the Internet.

Note: You can use the Open API and XML Tickets only if you have the Open API add-on module enabled in your ABBYY Recognition Server 3.5 license. See the ABBYY Recognition Server 3.5 Licensing page for details.

Google Search Appliance Connector

Finding necessary information scattered across different online resources and electronic document storages in a large organization can be a real challenge unless you use an enterprise search system like the Google Search Appliance. The Google Search Appliance indexes documents in various storage locations across the network, so that people can quickly find any document by keywords. However, a lot of valuable information is typically stored in the form of images (such as scanned TIFF or PDF files) and therefore is inaccessible for indexing by the Google search engine. Examples of such files are faxes, scanned contracts, newspaper and magazine archives. ABBYY Recognition Server and Google Search Appliance perfectly complement each other and allow indexing the both text files/web pages and scanned documents in TIFF, JPEG, PDF, DjVu and other formats. ABBYY Recognition Server unlocks image documents by applying OCR technology, and gives the Google Search Appliance access to their contents.

ABBYY Recognition Server and Google Search Appliance interact via the Google Search Appliance Connector that is installed as part of the Server Manager component. The Connector crawls network folders and sends documents in graphical formats to ABBYY Recognition Server. ABBYY Recognition Server recognizes the incoming documents and

pushes an XML feed with the recognized text to the Google Search Appliance for indexing. When this process is complete, the documents become available for searching.

IFilter for Microsoft Office SharePoint Server and Windows Desktop Search

Search for information is a vital part of any office workflow. As the organization grows, documents scatter across departments, file folders and ECM system, and search takes more and more valuable time. Microsoft® offers effective instruments to organize enterprise search on different levels, from centralized content storages to individual desktops. Microsoft Office SharePoint Server has powerful capabilities to search in SharePoint libraries and folders; Windows Desktop Search is helpful in finding files on desktop computers.

However, SharePoint Server and Windows Desktop Search index contents of files in certain document formats only, like HTML, RTF, DOC, XLS. Information contained in image files, such as JPEGs, or highly popular PDFs and TIFFs, remains uncovered. This means that content of scanned documents, faxes, letters, contracts, is invisible to the server, and those documents may not be displayed in search results.

ABBYY Recognition Server with its IFilter component extends Microsoft search capabilities over image documents. It “unlocks” the content of image files by means of OCR and makes it available for indexing by SharePoint Server and Windows Desktop Search. With ABBYY Recognition Server IFilter, the document search in the organization becomes truly encompassing.

ABBYY Recognition Server is integrated with Microsoft Office SharePoint Server and Windows Desktop Search as described below:

1. ABBYY Recognition Server is installed on a server computer (which may be separate from the SharePoint hosting machine). A special component, ABBYY Recognition Server IFilter, is installed on top of the SharePoint Server and/or user desktops to provide communication between the search system and the Recognition Server. The IFilter is a light component which consumes almost no computer resources to make sure it host’s performance remains on high level.

2. Each ABBYY IFilter receives image documents from the corresponding SharePoint or Windows Desktop search crawler and passes them to the Recognition Server.

3. ABBYY Recognition Server in the background performs high-quality OCR on the images and sends the recognized text back to the IFilter.

4. Microsoft search engine accepts the document contents from ABBYY IFilter and builds an index. The image then becomes discoverable via full-text search.
