Abstract
A very fast method for correcting the spelling of a word or phrase in a document proceeds in two steps: first applying a very fast approximate method for eliminating most candidate words from consideration (without computing the exact edit distance between the given word whose spelling is to be corrected and any candidate word), followed by a 'slow method' which computes the exact edit distance between the word whose spelling is to be corrected and each of the few remaining candidate words. The combination results in a method that is almost as fast as the fast approximate method and as exact as the slow method.
