... of the SMT system using automatically extracted paraphrase rules which can capture structures on sentence level in addition to paraphrases on the word or phrase level. Without extra paraphrase ... propose a novel approach to improve SMT via paraphrase rules which are automatically extracted from the bilingual training data. Without using extra paraphrase resources, we...

... Consequently, the quality and expressive power of the resulting gram- mar is tied to the quality and expressive power of the regular languages used to describe them. And the quality and expressive ... regular languages impact the parsing performance with those grammars. A second issue that we want to explore is how the grammars per- form when the quality of the training material is...

We used an in vitro-selected pistol-like (PL) DNAzyme as a DNA scaffold for designing a DNAzyme with dual catalytic ... As compared with PL DNAzyme, DRc DNA- zyme function seemed to have decreased sensitivity to the reaction temperature. DRc DNAzyme exhibited a broad functional range for temperatu...
