System and Method for Spelling Correction of Misspelled Keyword

摘要

A spelling correction system and method are provided. The system includes at least an input unit, a correct keyword candidate determining unit, and a misspelling correction unit. In the method, the input unit detects an input keyword entered by a user. If the input keyword is a misspelled keyword, the correct keyword candidate determining unit selects one or more correct keyword candidates for the input keyword and then returns the selected correct keyword candidates. The misspelling correction unit obtains a misspelling appearance probability of a pair of the input keyword and each correct keyword candidate, and also obtains a word appearance probability of each correct keyword candidate. Then the misspelling correction unit selects a specific correct keyword from among the correct keyword candidates by using the misspelling appearance probability and the word appearance probability.
