  • Method and apparatus for multilingual spelling corrections
    Patent number: 7558725
    Abstract: A system and method for multilingual spelling corrections employs a lexicon builder, which uses a metadata build process that extracts all words from the data source, along with their frequencies, to build a lexicon file using the data source with which a user will be working; and a spell checker algorithm, which determines the correct spelling of words used as input for a search of the data source by calculating a score value for words in the lexicon file according to a formula that distinguishes similarity between the input word from the user's search request and words contained in the lexicon file; and then rates the frequency of the input word against the words contained in the lexicon file. When a user inputs a word, words in the lexicon file are scored against the input word to determine a correct spelling or other spelling variant for the user to select.
