11. The system of claim 1, wherein the at least one fertility hypotheses generated by said fertility hypothesis generator is an integer.
1. A system for translating a series of source words in a first language to a series of target words in a second language, comprising: input means for inputting the series of source words; a fertility hypothesis generator operatively coupled to said input means for generating at least one fertility hypotheses for a fertility of a source word, based on the source word and a context of the source word; a sense hypothesis generator operatively coupled to said input means for generating sense hypotheses for a translation of the source word, based on the source word and the context of the source word; a fertility model operatively coupled to said fertility hypothesis generator for determining a probability of the fertility of the source word, based on the source word and the context of the source word; a sense model operatively coupled to said sense hypothesis generator for determining a probability of a target word being a correct translation of the source word, based on the source word and the context of the source word; and a decoder operatively coupled to said fertility and sense models for generating a list of target words for the translation of the source word, based on the probability calculated by said fertility model and the probability calculated by said sense model.
