This alternative is based on the observation that phrase-based decoding can be very naturally cast as a Traveling Salesman Prob- lem (TSP), one of the best studi...

... the bifunctional enzymes chorismate mutase–prephenate dehydratase and chorismate mutase–prephenate dehydratase were deleted. Monofunctional versions of the dehydratase and the dehydrogenase are provided ... interactions may be an easy way to increase enzyme stability. This hexameric variant, however, suffered a 200-fold decrease in catalytic efficiency. In contrast, the unstable monomeric va...

Suppose that the sentence (1) is misparsed as an active rather than a passive sentence due to the omission of the verb was, and that the prepo- sitional phrase ... destroyed at 220 nautical miles) Syntactic ambiguity and the resultant misparse induced by such an omission often leads to a mistranslation in a machine translation system, such as...

We also created two other simple SLMs: a class-based one (with the classes Song, Artist and Radiostation) and a model based on a variant ... This simple SLM (named MP3GFLM) has the same vo- cabulary as the Nuance Grammar and models the same language as the GF grammar. This model was chosen to see if we could increase flexibil...
