Translation Divergences in Chinese–English Machine Translation: An Empirical Investigation
What it is about
The authors take about 10,000 Chinese–English sentence pairs that have manually built parse trees on both sides. They align the two trees hierarchically, word alignments and constituents together, so that a word alignment cannot contradict a parse and create spurious divergences. On this parallel treebank they find translation divergences semi-automatically and sort them into seven types, among them lexical encoding (one-to-many alignments), transitivity, unaligned function words, category mismatch, reordering and dropped elements. The results show that divergences are far more varied than the textbook cases. Head-switching, a frequently cited example, is rare, while unaligned function words and reordering are common. Syntax-based hierarchical phrase rules capture most of the divergences, but the flat structures of existing treebanks give long rules that rarely repeat. The authors conclude that some divergences can be bridged by a shared semantic representation, while others are open-ended.
Ideas
- I1. Align words and tree nodes together, so that a concept is never attached to a head that its alignment contradicts. This addresses open problem 1 (attachment noise between two translations of one verse).
- I2. Run the seven-type classification on the verse pairs, one count per author pair, and use the counts to decide which author deltas to learn first. The divergence types can serve as classes of the residual in exact mode.
- I3. Count head-switching in the meta-world before building any rule for it. If the count is small, as the paper finds for Chinese–English, leave it out.
- I4. Unaligned function words are the largest class in the paper. Carry them as features of the meta token (open problem 4) instead of as tokens, and measure the residual with and without them.
For Mova
The code is tools/translate/meta.rs for the alignment and measure.rs for the classes. I1 is open problem 1, I2 and I4 are open problems 4 and 8. The paper's numbers are for a different language pair, so any counts must come from Mova's own Bible pairs.
