Product Advantages

Automated Conversion in PDF & PDF/A Formats

In ABBYY Recognition Server, precision OCR and PDF conversion processes are server-based and fully automated. ABBYY Recognition Server crawls specified “hot folders”, file shares and SharePoint libraries, converts discovered image documents into searchable files and delivers the results back into the same SharePoint library or a custom-specified destination. Minimized user involvement in the high-volume document conversion tasks significantly reduces the cost of the business process.
ABBYY Recognition Servers comes with advanced PDF and PDF/A creation features that meet the standards of long-term digital document archiving. Enhanced MRC compression technology allows creating small-size PDFs with high visual quality, well-suited for publishing online. PDF encryption can be used to prevent unauthorized viewing, printing or modifying the created PDF files. ABBYY Recognition Server can detect PDFs that were generated by a scanner and add a text layer to those files making them full-text searchable. If the PDF file already contains a text layer, ABBYY Recognition Server will evaluate its quality and replace it with a higher quality text layer if needed. At the same time, all bookmarks, annotations, metadata and attachments of the original PDF file will be preserved intact.
Defining custom file names, destination folders or metadata fields is easy with the convenient indexing and metadata extraction tools offered by ABBYY Recognition Server. Barcodes on the cover sheets or data that is contained within the documents can be captured, used for document classification and routing, and stored along with the document in the digital archive.

Creation of Full-Text Searchable SharePoint Libraries

State-of-the-art ABBYY OCR technology delivers the best results even on low quality documents and ensures high recognition accuracy. All scanned or faxed documents can be converted in searchable PDF or PDF/A in order to be indexed by Microsoft SharePoint and become discoverable.
ABBYY Recognition Server provides integration with Microsoft SharePoint on multiple levels. It can be set up as a front-end to the SharePoint server to consistently convert all incoming image documents into searchable PDFs prior to their upload in Microsoft SharePoint. Image documents that are already stored in SharePoint libraries can be automatically converted within the libraries without any user interference. In addition to that, newly added documents that are uploaded by users as images will be found, processed by OCR engine and stored back in the library in a searchable format.
Document conversion is performed as a background process and is fully invisible for SharePoint end users. Their experience of working with SharePoint will not have to change, while ABBYYY Recognition Server will ensure that all incoming documents are consistently processed and made full-text searchable.

An Enterprise-Level Document Conversion Service

With ABBYY Recognition Server, OCR is not limited to a desktop PC or its operator’s work hours. The service that resides on a server is available to all users or select groups of users regardless of their location or access hours.
Centralized installation, configuration, and administration of ABBYY Recognition Server make it a cost-efficient enterprise-wide solution as opposed to desktop applications that need to be maintained by IT personnel on multiple workstations.
Users can start using the document conversion service right away, without having to learn what OCR is. They simply select a format they want to convert their document into (searchable PDF, PDF/A, Microsoft Word or Excel), and receive the requested file.
Because the document conversion process is completely automatic and hidden from the user, ABBYY Recognition Server is equally well suited for a single- or multi-tenant user environment. The installation can be easily scaled to process documents from added clients without a decline in productivity. A flexible system of priorities allows automatically moving important documents ahead of the queue.

Automatically digitize your documents.

How It Works?

1. Flexible Import Options

Import from Network/FTP Folders
ABBYY Recognition Server can automatically import images from the following network resources:

  • Network folder
  • FTP folder (e.g. if images are to be uploaded from remote locations)
  • E-mail folder (e.g. if users send images for conversion by e-mail)

File Input Formats

  • TIFF / Multipage TIFF
    Compression methods: Unpacked, CCITT Group 3, CCITT Group 3 FAX(2D), CCITT Group4, PackBits, JPEG, ZIP, LZW
  • JPEG, JPEG 2000
  • PDF
  • DjVu
  • BMP
  • PNG
  • PCX, DCX

2. Scanning Station

Scanning Station provides functionality for batch scanning and preparation of images for further processing:

  • Scanning via TWAIN, WIA and ISIS.
  • Quick image preview.
  • Image preprocessing (rotation, deskew, despeckle, etc.).
  • Document separation by barcodes / blank pages / fixed number of pages.

For images scanned in a batch, ABBYY Recognition Server offers several built-in document separation options: by blank sheets, barcode sheets, or barcodes stuck or printed on the first page of each document. Additional custom rules based on the recognized text can be created using scripting.

OCR is done on a Processing Station automatically. It is possible to connect several computers to the Server Manager as Processing Stations, and the Server Manager will balance the workload among these stations evenly. This will result in much faster processing of documents.

The OCR and barcode recognition technologies implemented in Recognition Server deliver unprecedented accuracy, support various types of text and support the most popular 1D and 2D barcodes. The OCR process has extensive language support. The supported languages include 198 languages including Latin, Cyrillic, Greek, Arabic, Chinese, Japanese, Korean, Vietnamese, Hebrew, Yiddish and Thai. European languages written in Gothic fonts are also supported.

To preserve the original document layout, ABBYY Recognition Server uses Adaptive Document Recognition Technology (ADRT). ADRT significantly improves document layout retention when saving documents to DOC and RTF formats. The logical structure of an entire document is reproduced, including headers, footers, footnotes, page numbers, table of contents linked to document sections and notes to pictures and diagrams.

Sometimes there is a need to process important documents which have to be recognized with exceptional accuracy. At the same time, the quality of the scans may not be perfect, suffering from low resolution and unwanted noise. In this case it is very important to have a reliable quality assurance mechanism.

Automatic quality control allows the administrator to set a threshold for recognition accuracy: documents with poor-quality text will not be converted, but rather stored in a separate folder for special treatment.

Verification Station

A client station for proofreading recognition results. Verification can be enabled for all pages or it can be based on the accuracy threshold. Verification permissions management is supported.

Indexing Station

A client station for document indexing and classification.

ABBYY Recognition Server is a server-based software for automating document processing, OCR and PDF conversion in enterprise and service-based environments. Its architecture makes it easy to deploy document processing solutions that scale to any size, with significant time and cost savings.

ABBYY Recognition Server automatically converts large volumes of paper documents or document images into fully searchable electronic text suitable for business processes including archiving, e-discovery, and enterprise search. It enables automated, unattended document processing that can be managed and accessed from within an organization or remotely. Recognition Server can also connect with a variety of back-end systems and third-party applications, integrating via Scripts, XML tickets, a Web-service API or a COM-based API. ABBYY intelligent OCR and PDF conversion technology delivers highly accurate document conversion with recognition of up to 190 languages.


ABBYY Recognition Server consists of several components, which can be installed on one or many computers in a LAN. The main components are:

  • Server Manager — a central service component, which controls the document processing queue and distributes the tasks among the stations.
  • Processing Station — a service that performs recognition and document conversion.
  • Scanning Station — a client station for batch scanning and image pre-processing.
  • Indexing Station — a client station for document indexing and classification.
  • Connector to Google Search Appliance™ (GSA) — a component that allows Google Search Appliance to use ABBYY Recognition Server for extracting content from document images .
  • Connector to Microsoft® Search Systems (IFilter) — a component that allows Microsoft Office SharePoint Server and Windows Search to use ABBYY Recognition Server for extracting content from document images.
  • Remote Administration Console — a client console used for configuring and monitoring Recognition Server.


Document Processing


ABBYY Recognition Server processes each image file according to a workflow — a set of processing parameters predefined by the administrator. ABBYY Recognition Server can run several workflows with different parameters simultaneously. Each workflow corresponds to a unique input source (a folder, a SharePoint library or a mailbox).

Processing Steps

A workflow in ABBYY Recognition Server typically includes up to six configurable stages. Each workflow runs independently of others according to its own schedule and priority.


Six Stages of Document Processing

1. Scanning/Import of images. Images can be either scanned by an operator on the Scanning Station and then sent to ABBYY Recognition Server, or automatically imported by ABBYY Recognition Server from an input folder (network folder, FTP folder, SharePoint® library, or mailbox). ABBYY Recognition Server arranges image files in a queue to process them automatically according to priorities.

2. Recognition. The OCR process runs automatically on the Processing Station. If several Processing Stations are installed in the system, the files will be distributed among these Processing Stations evenly for optimal performance. Deploying additional Processing Stations brings a linear increase in OCR speed.

3. Verification (optional). In some cases, for example when digitizing books, verification of the recognition results might be necessary. Verification Stations allow operators to check all documents or only documents below a certain accuracy threshold.

4. Document separation (optional). When the batch scanning or import is performed, a document separation may be required. The documents can be separated using blank separator sheets, barcodes or by fixed number of pages per document. Separation can also be done according to a scripted rule.

5. Classification and indexing (optional). Indexing of documents can be done either automatically by a script, or by an operator on the Indexing Station, which allows the operator to manually select the document type and assign document attributes. The operator can also verify the data that has been populated by the script.

6. Export. In the final stage, ABBYY Recognition Server delivers the output documents to their destination (which can be a network folder, a SharePoint document library, or an e-mail address). Additionally, scripts can be applied for intelligent routing and delivery of documents to ECM systems based on document types and attributes.

Recognition Server is administered via a convenient interface based on the Microsoft Management Console. It allows the administrator to configure the system and monitor its activity: to set processing parameters, to manage licenses, stations, user permissions, processing queues and to view logs.

With the priority management and scheduling features, the administrator can control the order in which the documents are processed and use the stations’ hardware resources efficiently by scheduling OCR for night hours or weekends.
