Abstract
An “impostor profile” for a language is used to determine whether documents are in that language or no language. The impostor profile for a given language provides statistical information about the expected results of applying a language model for one or more other (“impostor”) languages to a document that is in fact in the given language. After a most likely language for a test document is identified, the impostor profile is used together with the scores for the test document in the various impostor languages to determine whether to identify the test document as being in the most likely language or in no language.
