MonoTrans 2 : An Asynchronous Human Computation System to Support Monolingual Translation

In this paper, we present MonoTrans2, a new user interface to support monolingual translation; that is, translation by people who speak only the source language or only the target language, but not both. Previous systems built to support monolingual translation have assumed a synchronous translation process, which it turns out not necessary. In an experiment translating children's books, we show that MonoTrans2 is able to substantially close the gap between machine translation and human bilingual translations. These results show that speakers of both languages do not have to interact in real time to translate collaboratively. Author
