In this paper we look at the problem of cleansing noisy text using a statistical ma- chine translation model. Noisy text is pro- duced in informal communications such as Short Message Service (SMS), Twit- ter and chat. A typical Statistical Ma- chine Translation system is trained on par- allel text comprising noisy and clean sen- tences. In this paper we propose an un- supervised method for the translation of noisy text to clean text. Our method has two steps. For a given noisy sentence, a weighted list of possible clean tokens for each noisy token are obtained. The clean sentence is then obtained by maximizing the product of the weighted lists and the language model scores.
