Abstract
A method for enhancing source-language coverage during statistical machine translation. The method including receiving an input string in a source language for translation into a target language. Extracting a paraphrase representation of the input string from a data repository comprising a corpus. Generating a word lattice structure using a directed acyclic graph representation having a plurality of nodes with edges extending there between. The words of the input string and the extracted paraphrase representation each having a respective edge in the directed acyclic graph. Labelling each of the edges with a word and a probability, the probability weighing assigned to the edges associated with the words of the input string being higher than the probability assigned to paraphrases derived from the input string.
