The importance of term transliteration can be realized from our analysis of the terms used in 200 qualifying sentences that were randomly selected from English-Chinese ... organized, much invaluable information can be obtained from this large text corpus.

... integrating lin- guistic information in translation systems. Syntax- based MT often suffers from inadequate constraints in the translation rules extracted, or from striving to combine these rules ... advancing from structures which mimic lin- guistic syntax, to learning linguistically aware latent recursive structures targeting translation, we achieve significant improvements in tr...

In our experiments, we used the translations from Span- Table 2: Improved translation results for the con- sensus translation computed from 5 translation outputs on the Chinese-English ... trans- lations. These translations can be improved if we compute a consensus translation from the output of at least two different speech translation systems. From each system, we...

For this purpose, we assume a generative model for multilingual corpora, where each sentence is generated from a language ... borrowing from nearby languages, and 3) the innate abilities of humans (Chomsky, 1965). We assume hidden commonalities in syntax across languages, and try to extract a common grammar fr...
