Verification
To improve recognition accuracy, ABBYY FormReader 6.0 may
submit data for manual verification by the operator. FormReader
offers three verification methods
1.
Group verification. This is the ideal method for checking data
belonging to a particular limited set, e.g. digits. Group verifica
tion groups together uncertainly recognized characters of the
same kind (e.g. all 3's) and displays them to the operator. The
operator will easily spot the "odd one out" and correct it. This is
more efficient than going through the whole text. Group verifi
cation greatly speeds up data checking, as the operator can con
firm hundreds of characters by simply pressing "Enter".
2. Context verification. Context verification
displays two lines  recognized text and the
corresponding section of the original image.
The operator may compare the two texts and
either confirm or correct the characters.
All the verification methods described above serve one purpose  t o minimize the number of buttons that the operator has
to press . It is the number of buttons the operator presses that has the most impact on the speed and quality of verification, and
ultimately, on the quality of entered data. In most cases even characters highlighted by the program as "uncertainly recognized"
have been recognized correctly and just need to be confirmed by the operator. Even if the program has encountered a rare word
that is not present in any of its dictionaries and highlighted it on all forms, the operator needs to press Enter just once to con
firm all these highlights.
Group verification of digits.
Inform verification.
3. Inform verification. If data checks detect serious errors on a
form, such form will be marked with a special colour flag. Then
the form will be submitted to the operator so that the opera
tor may review all the suspect fields and make the necessary
corrections.
Context verification of uncertain characters.
