User Lexicons (Readiris Corporate only)
During recognition, Readiris is assisted by linguistic databases to
recognize text correctly. These linguistic databases are standard
lexicons and are available for every supported language.
As powerful as these standard lexicons may be, the recognition
accuracy can still be boosted using customized user lexicons. By
means of user lexicons, Readiris can recognize technical, scientific,
legal and company-specific terminology it would otherwise have
difficulty with.
See the section Using User Lexicons for more information.

By means of Interactive learning you can train the recognition
system on fonts and character shapes, and correct the recognition
results if necessary. During interactive learning, any characters the
recognition system isn't sure of are displayed in a preview window,
in combination with their parent word and the proposed solution.
Interactive learning can substantially enhance the accuracy of the
recognition system and is particularly useful when recognizing
distorted, defaced forms. Interactive learning can also be used to
train Readiris on special symbols it is unable to recognize initially,
such as mathematical and scientific symbols and dingbats.
To enable interactive learning:
 On the Learn menu, click Interactive Learning.
 Click Save to process the document. Readiris enters the
interactive learning phase.
