ABBYY FineReader 12 User’s Guide

1. Rather than differentiating between some similar yet different characters, ABBYY
FineReader recognizes them as one and the same character. For example, the straight ('),
left (‘), and right (’) quotes will be stored in a pattern as a single character (straight quote).
This means that left and right quotes will never be used in the recognized text, even if you
try to train them.
2. For some character images, ABBYY FineReader will select the corresponding keyboard
character based on the surrounding context. For example, an image of a small circle will be
recognized as the letter O if there are letters immediately next to it and as the number 0 if
there are digits next to it.
3. A pattern can only be used for documents that have the same font, font size, and
resolution as the document used to create the pattern.
4. To be able to use a pattern later, save it to a file. See "What Is a FineReader Document?"
for details.
5. To recognize texts set in a different font, be sure to disable the user pattern by selecting
the Use only built–in patterns option in Tools > Options… > Read.
Editing a user pattern
You may wish to edit your newly created pattern before launching the OCR process. An incorrectly
trained pattern may adversely affect OCR quality. A pattern should contain only whole characters or
ligatures. Characters with cut edges and characters with incorrect letter correspondences should be
removed from the pattern.
1. On the Tools menu, click Pattern Editor….
2. The Pattern Editor dialog box will open. Select the desired pattern and click the Edit…
button.
3. In the User Pattern dialog box that opens, select a character and click the Properties…
button.
In the dialog box that opens:
o Enter the letter that corresponds to the character in the Character field
o Specify the desired font effect (bold, italic, superscript and subscript) in the Effect
field.
Click the Delete button in the User Pattern dialog box to delete a character that has been trained
incorrectly.
If Your Text Contains Too Many Specialized or Rare Terms
ABBYY FineReader 12 checks recognized words against its internal dictionary. If the text you want
to recognize contains many specialized terms, abbreviations and names, you c an improve
recognition accuracy by adding them to the dictionary.
1. On the Tools menu, click View Dictionaries….
2. In the User Dictionaries dialog box, select the desired language and click View….
3. The Dictionary dialog box will open. In this dialog box, type a word and click Add or
select a word and click Delete.
If the dictionary already contains the word you are trying to add, a message stating that the word
you're trying to add is already in the dictionary wil l be displayed.
You can import user dictionaries created in previous versions of ABBYY FineReader (i.e. 9.0, 10 and
11).
