We describe a syntax-based algorithm that au- tomatically builds Finite State Automata (word lattices) from semantically equivalent transla- tion sets. These FSAs are good representa- tions of paraphrases. They can be used to ex- tract lexical and syntactic paraphrase pairs and to generate new, unseen sentences that express the same meaning as the sentences in the input sets. Our FSAs can also predict the correctness of alternative semantic renderings, which may be used to evaluate the quality of translations.
