<p><P>PROBLEM TO BE SOLVED: To provide a method for aligning a sentence of a first corpus into a sentence of a second corpus. <P>SOLUTION: This method includes formation of an aligned pair of sentences by aligning a sentence boundary of sentences of a first corpus into a sentence boundary of sentences of a second corpus by adapting an alignment model based on length. Next, using the aligned pair of sentences, a translation model is trained. After finishing the training, using the translation model, a sentence of the first corpus is aligned into a sentence of the second corpus. According to a mode of this invention, using pruning, the number of sentence boundary alignments considered by the alignment model based on the length and the number of sentence boundaries considered by the translation model are reduced. In a further mode of the invention, the model based on the length uses Poisson distribution. <P>COPYRIGHT: (C)2004,JPO</p> |
