4.2 Weighting Syntactic Phrases
- Why did syntactic phrases hurt, according to Koehn et al.?Not because they are more reliable but too few: giving syntactic pairs extra weight (counting them twice or a decoder bonus) didn’t help, and penalizing them didn’t hurt much. Useful pairs like German “es gibt” ↔ “there is” aren’t constituents, and “with regard to” or “note that” often have simple one-word translations.
