1. A computer-implemented method of identifying a language of a message, the method comprising: performing a plurality of language detection tests on text, each language detection test determining a respective set of scores, each score in the set of scores representing a likelihood that the message is in a respective language of a plurality of different languages; providing one or more combinations of the score sets as input to one or more distinct classifiers including a first classifier and a second classifier, wherein the first classifier was trained using outputs from a first combination of the language detection tests and the second classifier was trained using outputs from a different second combination of the language detection tests; obtaining as output from each of the one or more classifiers a respective indication that the message is in one of the plurality of different languages, the indication comprising a confidence score; and identifying the language of the message based on one of the confidence scores.
