Abstract: Methods and apparatus are provided for automatically detecting spelling errors in one or more documents, such as documents being processed for the creation of a lexicon According to one aspect of the invention, a spelling error is detected in one or more documents by determining if at least one given word in the one or more documents satisfies a predefined misspelling criteria, wherein the predefined misspelling criteria comprises the at least one given word having a frequency below a predefined low threshold and the at least one given word being within a predefined edit distance of one or more other words in the one or more documents having a frequency above a predefined high threshold; and identifying a given word as a potentially misspelled word if the given word satisfies the predefined misspelling criteria.

Abstract: Faults and errors are diagnosed from a repository of directed graphs. Subsets of all the possible questions and answers in the fault diagnosis process are encoded as directed graphs. Downloading subsets from a repository to a remote user substantially reduces the number of transmissions between the user and the repository.
