Installation and Configuration of Recognition Servers

Please note: this documentation concerns to the prerequisites and specifics wich aren't described comprehensively in the Abbyy Recognition Servers manual, regarding to the magazine "Daheim" and comparable digitized media.

These settings can be accepted as provided. It saves time-consuming troubleshooting.

Minimal prerequisites are:

• Server Manager
• Verification Station

Choosing the user account the server is running

The Recognition Server-manual is related to a Windows based domain and Windows network shares. If the OCR results are to be saved onto a network sare, you need to select a user with privileges on accessing the network. The local system account does have comprehensive privileges on the local machine, bot none on the network. It's advisable to choose the network service account. In our case we had Novell domain and Novell network shares. These seem to be incompatible in this case. The error message of Recognition Server was cannot access drive xxx (the network share). Thus we saved the OCR results on the local server and copied them onto a network share by using a synchronizing programm.

Workflow settings

Explanation of "Entzerren/dewarping":

This option arranges the picture on the basis of straight lines. If they are like in this example, a trapeze-shaped flag, the result looks like this:

Das Programm richtet die lange Kante der Fahne horizontal aus, da es diese als Referenz für die Ausrichtung ansieht. Daher sollte in solchen Fällen die Option Entzerren deaktiviert werden.

Qualitätskontrolle

Für Dokumente mit sehr einfachen Formatierungen (z.B. reiner Fließtext) und mit nur wenigen Abbildungen, kann Keine Überprüfung gewählt werden. Ein Beispiel für eine relativ unproblematische Seite:

Bei Dokumenten mit aufwändigeren Formatierungen sollte hingegen Alle Dokumente überprüfen gewählt werden, da sonst häufig die segmentierten Bildunterschriften entweder in den Fließtext mit einbezogen oder als separates Textsegment erfasst wird. Das bringt die Lesereihenfolge durcheinander. Ein Beispiel für ein komplexe Formatierung:
