Ghotit Spell Checker

The Ghotit Spell Checker application was designed to be a unique context spellchecker. Ordinary spellcheckers do not take into account the context of the sentence the word is being used.

Correcting really badly spelled words
In the world of spellchecking, the degree of how badly a word is misspelled is measured by the editing distance of the misspelled word to the intended word. The tradeoff is as follows: the longer the editing distance, the longer the list of candidate words that will be offered. Since ordinary spellcheckers can not properly grade the long list of alternatives, this long list is seen as adding "noise" to the spellchecking algorithm.

Ordinary spellcheckers are tuned for people with mild spelling and typing mistakes, and therefore prefer to offer a relatively short editing distance in order to minimize the list of candidate words.

Here context spellchecking algorithms come to play. Once an effective context spellchecking is introduced, a larger editing distance can be introduced, since the spellchecker can leverage the context of the sentence to optimize the suggested word list and remove the unwanted, out-of-context words.

Identify misused words
Ordinary spell checkers either do not or provide very limited identification of misused words. If a spellchecker does not have or has very simplistic context spellchecking algorithms, then it simply can not identify misused words. Without appropriate context knowledge, the spellchecker does not have any information to provide for a misused word, and will leave such words as unmarked. In such situations, the writer will not even know that he has errors in his writing.

Ghotit context spellchecking algorithms have been targeted to effectively identify misused words. A word that is spelled correctly, but has been identified as a misused word according to the words' sentence, will be marked as such, with a candidate list of words based on the exact context of the word.
