... form valid MW-HW collocations with their head words. We assume that all the surround- ing words within a certain window size centered on the given position to generate a measure word are potential ... presented in Section 2.5. The measure word with the highest probability will be chosen. There are two reasons why we perform measure word generation for SMT systems as a post- pro...
