We address the task of handling unknown terms in SMT, suggesting a more extensive use of source-language monolingual resources. We present a conceptual extension to prior work by allowing translations of entailed texts rather than exact paraphrases only. We further suggest a method for performing this process efficiently. Our experiments show that the proposed approach substantially increases translation coverage while maintaining translation quality.
