Scanno
A scanno (or a 'scanning typo') is an incorrect character in an OCR text.
- EXAMPLE: table in the page image appears as tahte in the OCR text.
- Distributed Proofreaders's (DP's) coining of the word scanno was inspired by the word typo, a typographical error.
One of Distributed Proofreaders's (DP's) primary goals during the proofing process is to correct all of the scannos in the OCR text.
- See the Proofing Advice page, which contains links to lists of common scannos in various languages.
DP tracks specific types of scannos to make the process of identifying them easier. Below is a list of specific types of scannos:
stealth scanno
A stealth scanno (also stealtho) is a specific type of scanno that occurs when a character forms a valid word in the OCR text, but is not the word that appears in the page image.
- EXAMPLE: and in the page image appears as arid in the OCR text.
Distributed Proofreaders's coining if this term was inspired by stealth bombers, which are undetectable by radar, because stealth scannos are undetectable by normal spellcheck utilities.
