The Value of Monolingual Crowdsourcing in a Real-World Translation Scenario: Simulation using Haitian Creole Emergency SMS Messages

We report on its use in the WMT 2011 Haitian Creole to English translation task, showing that MonoTrans2 translated 38% of the sentences well compared to Google Translate's 25%.
