Tunable Distortion Limits and Corpus Cleaning for SMT
Sara Stymne, Christian Hardmeier, Jörg Tiedemann, Joakim Nivre · 2013
We describe the Uppsala University system for WMT13, for English-to-German translation. We use the Docent decoder, a local search decoder that translates at the document level. We add tunable distortion limits, that is, soft constraints on the maximum distortion allowed, to Docent. We also investigate cleaning of the noisy Common Crawl corpus. We show that we can use alignment-based filtering for cleaning with good results. Finally we investigate effects of corpus selection for recasing. 1
