33. The method of claim 32, further comprising the step of implementing a confidence measure to exclude unreliable fertility-context and sense-context events from being accumulated.
32. The method of claim 19, wherein the method is trained on a sentence-aligned training text including a plurality of sentences in the source language and a plurality of sentences in the target language, wherein each sentence in the plurality of source language sentences is a translation of a corresponding sentence in the plurality of target language sentences, and a training portion of the method comprises: determining an alignment between the words of each of the plurality of source language sentences and the corresponding target language sentence; accumulating fertility-context events from the alignments for at least some occurrence of the source word in a source language sentence, each fertility-context event including a number of target language words that the source language word is aligned to, the source language word, and the context of the source-language word; accumulating sense-context events from the alignments for at least some occurrence of the source word in a source language sentence, each sense-context event including the target word, the source-language word to which the target language word is aligned, and the context of the source-language word; and wherein the probability of the fertility of the source word and the probability of the target are determined using the accumulated fertility-context and sense-context events, respectively.
