... those trees and use them in syntactic parsing. Although prosodic structures are not syntactic structures, they do correspond to each other in some systematic ways. Just as there are ways to ... ways. Just as there are ways to transform syntactic structures to prosodic structures (e.g. Abney 1992), prosodic structures can also provide clues to syntactic structur...

The second approach is to use training data of aligned document pairs to...

Word alignment models have not stood still in re- cent ... compu- tation to the HMM model (Ney and Vogel, 1996), but which incorporates a novel, syntax-aware distor- tion component which conditions on target language parse trees. These...

... approaches to morphology and provenance in machine translation are possible. We have chosen to implement our approach as exten- sions to lexical weighting (Koehn et al., 2003), which is nearly ubiquitous, ... mapping from s-features to sentence weights was chosen to optimize ex- pected TER on held-out data. A drawback of this method is that we must now learn the mapping from s-featu...

It is an oriented multidocument sum- marization task in which a category is attributed to a cluster of 10 source documents to be summa- rized ... appropriate to address it. The idea to use an IE system for summarization can be traced back to the FRUMP system (DeJong, 1982), which generates brief summaries about vari...
