12. The system of claim 11 , wherein the translating module is further configured to: calculate BLEU (Bilingual Evaluation Understudy) scores for each candidate translation unit; and determine scoring functions for the candidate translation units.
11. A system for statistical machine translation (MT) parameter tuning, the system comprising: a memory for storing executable instructions for tuning statistical MT parameters; and a processor for executing the executable instructions stored in memory, the executable instructions comprising: a text analyzing module to sample a pair of candidate translation units from a set of candidate translation units corresponding to a source unit, each candidate translation unit corresponding to numeric values assigned to one or more features; a communication module to receive an initial weighting value for each feature; a mapping module comparing the pair of candidate translation units to produce a binary result; and a translating module to adjust the initial weighting values to produce modified weighting values based on the binary result.
