Báo cáo khoa học: "Two Easy Improvements to Lexical Weighting" doc

... 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, ... introduce two simple improvements to the lexical weighting features of Koehn, Och, and Marcu (2003) for machine translation: one which smooths the probability of translatin...

... we use to mark constituent structures. At that time, those cantillation marks were intended to record the correct way of reading or chanting the Hebrew text: how to group words into phrases ... correspond to each other in some systematic ways. Just as there are ways to transform syntactic structures to prosodic structures (e.g. Abney 1992), prosodic structures can also pro...

... task at TAC is to motivate a move towards abstractive approaches. 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...

... corresponds to a unique node. • The nodes are arranged into a hierarchy of levels, with the bottom level containing n 2 nodes and the top containing a single root node. Each level, except the top, will ... between the context vectors representing each term. Manual creation of lexical semantic resources is open to the problems of bias, inconsistency and limited coverage. It is difficult...
