More precisely, our approach makes use of a hybrid implementation of multiple alignment combination within phrase-based SAPE (PB-SAPE) and hierarchical PB-SAPE (HPB-SAPE) and a system combination framework (a multi-engine pipeline) -that combines the best translations from the enhanced PB-SAPE, HPB-SAPE and the raw MT output.
figure 2 depicts the process of generating additional alignments where the solid links represent edit distance based alignments and the dashed links represent the newly established alignments.
