... for train- ing word alignment model. The experimental re- sults show that our proposed method was effec- tive in improving the performance of the word alignment model by using synonym pairs includ- ing ... improve word alignment quality is to add linguistic knowledge derived from a monolingual corpus. This monolingual knowl- edge makes it easier to determine corresponding words cor...

... models. In order to obtain fine-grained interpolation models, we in- terpolate the three kinds of parameters using dif- ferent weights, which are obtained in the same way as described in Wu et ... Chinese-Japanese word alignment, we build an interpolated model by interpolating the induced model and the original model. Generally, we can interpolate the induced model and the o...

The window is set to 4, since the dynamic programming approach is very fast in recovering from local errors. When such a sequence is found, all the segments included in it are marked as...
