Unlike traditional language models, however, grounded language models ... necessary to account for the words not included in the grounded language model itself (i.e. stop words, proper names, low frequency words).

In this paper we introduce a confidence mea- sure for word alignment, which is robust to extra or missing words in the bilingual sentence pairs, as well as word alignment ... probability of the aligned word pair with the translation probabilities of all the target words given the source word. If a word t occurs N times in the target sentence, for...

To perform translation between languages ... those using pivot language and those using a small bilingual corpus or scarce resources. For the first kind, pivot languages are employed to translate queries in cross -language inf...
