Mark level

- General

If you select the General option, the adjacent drop-down list gives you a choice of three levels of confidence. The default level is Medium. The other choices are Low and High.
A setting of
Low
means that you accept a lower level of recognition confidence. There may be fewer mark flags in the results.A setting of
Medium
means that you accept a moderate amount of recognition confidence. There may be more mark flags than with theLow
setting.A setting of
High
means that you require a greater degree of recognition confidence. There may be more mark flags than with the other settings. - Specific
-
If you select the Specific option, you can specify a precise level of confidence ranging from 0 to 100.
The level value for
Low
is 75.The level value for
Medium
is 85.The level value for
High
is 95.
Spell check and Spell check flag
Select the
Spell check
option to have unrecognized words compared to entries in a dictionary of known
values. If they do not match, a spell check flag is inserted in front of the non-matching word. A default dictionary is used, based
on the currently selected language. You can also specify a custom dictionary by selecting a text file in the
Document Class Properties window
OCR tab.
Use the
Spell check flag
to specify a character to indicate words that are not found in a dictionary.
You can specify only a single character. Note that the following occurs when you have enabled and specified a spell check flag:
-
For a single language: All words are flagged when the selected language does not have a dictionary.
-
For multiple languages: Only words not found in the dictionary are flagged. If the selected language does not have a dictionary, then the word is not flagged.
If a word is flagged twice, once with the spell check flag and once with the confidence mark flag, the spell check flag is first, followed immediately by the confidence mark flag. However, if the two flags are set to the same character (for example ^), both flags are represented by a single character. This is the default behavior.
Non-natural language
Use this check box to specify unusual character strings that should be detected as valid entries for the selected language. For example, if the engine recognizes a character string such as 11Mar2014 but produces an unexpected result such as llMar2014, you can do the following to ensure correct results:
-
Select the
Non-natural language
check box. -
Use the text entry field below the check box to specify the characters that are valid to include. For example, if you specify 1 as a valid character string the engine can successfully interpret "11Mar2010" as a valid character string and produce the expected result.
