A Random Forests Text Transliteration System for Greek Digraphia

Abstract : Greeklish to Greek transcription does undeniably seem to be a challenging task since it cannot be accomplished by directly mapping each Greek character to a corresponding symbol of the Latin alphabet. The ambiguity in the human way of Greeklish writing, since Greeklish users do not follow a standardized way of transliteration makes the process of transcribing Greeklish back to Greek alphabet challenging. Even though a plethora of deterministic approaches for the task at hand exists, this paper presents a non-deterministic, vocabulary-free approach, which produces comparable and even better results, supports argot and other linguistic peculiarities, based on an ensemble classification methodology of Data Mining, namely Random Forests. Using data from real users from a conglomeration of resources such as Blogs, forums, email lists, etc., as well as artificial data from a robust stochastic Greek to Greeklish transcriber, the proposed approach depicts satisfactory outcomes in the range of 91.5%-98.5%, which is comparable to an alternative commercial approach.
