... translation chosen by forest-based consensus decoding. The consensus translation reconstructs content lost in the Viterbi translation. We attribute gains from fast consensus decoding to this increased predictive ... about the correct translation from the en- tire forest. In particular, consensus decoding with BLEU chooses translations using n-gram count expectations E[c(e...

Introduction Computers can contribute to translation either ... some tedious aspects (such as dictionary look-up) of the translation work, either interactively via a terminal or by batch processing overnight.

One is to run both models and ... During decoding, a set of SW’s in each sentence, say S, is collected. If the cosine similarity between T and S is greater than a certain threshold, the domain-specific model is selected for...
