As a further example, consider the translation of the NP the total at risk a year.
when fragments from systems A and B are combined, the "best" translation is comprised of the chunk combination AAB, that is, the three-chunk combination in (44), with the first two chunks obtained from system A, and the last from system B: the translation of this NP improves when the performance of system AB is Translation quality improves when system databases are seeded with more translation pairs and when more knowledge sources are used: Measuring % translation quality using fragments derived from combinations of on-line MT systems.
