The Ocr Tab - Xerox DocuMate 4790 User Manual

The OCR Tab

The options shown on the OCR tab window are for spellchecking scanned text, replacing missing or
unrecognized characters, and setting the speed and quality levels of the OCR processing.
1. Choose the options you want from the OCR window.
Languages in Document—Click on the language(s) in list that correspond to the languages in the
documents to be scanned. You can click on multiple languages. These are the languages that will
be recognized during the OCR process. For faster and more reliable language recognition, select
only the languages in the documents.
The languages are in alphabetical order. Type the first letter of a language's name to jump to its
section in the list.
Use languages and dictionaries to improve accuracy—Select this option to automatically check
the validity of the recognized words. An OCR engine looks at each letter or symbol on the page
individually, then "guesses" what the letter or symbol is based on the shape. Therefore, the OCR
engine may have more than one guess for a particular letter or symbol, a "best guess", a "second-
best guess", and so on. This option tells the OCR engine to look through the dictionary to validate
its best guess for the letters in that word; if its best guess is not in the dictionary, it checks for the
second-best guess, and so on.
For example, if the word "house" appears in the original document but the OCR engine is 75%
sure that the "o" is actually an "a", the finished document would have the word "hause". Turning
this option on tells the OCR engine to look at the other letters in the word, check to see which
version of the word is in the dictionary, and output the correct word "house" in the final document.
The OCR engine does not automatically correct misspelled words that were present in the original
document.
When dictionaries are selected, the terms in those dictionaries are used to check the spelling. If
this is option is not selected, User Dictionaries and Professional Dictionaries cannot be selected.
