After performing OCR, a manual entry station running BSCAN-DE can correct all characters that were read with low confidence. Standard OCR engines cannot know precisely which characters they have misread, but they do indicate which characters were read with low confidence. For example, text with a 1% actual OCR error rate might send 4% of the characters to be corrected by RCC stations. Keyers can work quickly and catch any errors they make in the next stage.
Rapid Character Review
All characters keyed in the RCC stage are presented in the RCR stage for review. Using RCR's sorted character screens, text can be rapidly and accurately reviewed. RCR shows one or more screens for each character code -- a screen of 'A' characters, then 'B' characters, and so on. With RCR, it is quite easy to spot errors. After clicking with the mouse on each error, a final RCC screen is presented for correction.
