S-Capade: Spelling Correction Aimed at Particularly Deviant Errors

摘要

S-capade (spelling correction aimed at particularly deviant errors) is a phonemic distance based spellchecking tool (Source code repository may be found in the references section [35].) intended for the correction of misspellings made by children. Whilst typographic misspellings typically deviate from the target by only one or two characters, children's misspellings tend to be more phonetic. They are influenced both by how the child perceives the pronunciation of a word and by the letters they choose to represent that pronunciation. As such, these misspellings are particularly deviant from the target and can negatively impact the performance of conventional spellcheckers. In this paper we demonstrate that S-capade is capable of correcting a significant portion of misspellings made by children where conventional correction tools fail.
