For resource-limited language pairs, coverage of the test set by the parallel corpus is an important factor that affects translation qual- ity in two respects: 1) out of vocabulary words; 2) the same information in an input sentence can be expressed in different ways, while current phrase-based SMT systems can- not automatically select an alternative way to transfer the same information. Therefore, given limited data, in order to facilitate trans- lation from the input side, this paper pro- poses a novel method to reduce the transla- tion difficulty using source-side lattice-based paraphrases. We utilise the original phrases from the input sentence and the correspond- ing paraphrases to build a lattice with esti- mated weights for each edge to improve trans- lation quality. Compared to the...
