[PDF] Top 20 Edinburgh’s Syntax Based Machine Translation Systems

... These parameters are language-dependent and should be set to values that best represent the char- acteristics of the target trees on which the rule ex- tractor is trained on. Therefore the style of the treebanks used for ... See full document

... the syntax-based generation system is weakly analogous to N -gram model insertion for syntax-based statistical machine translation sys- tems, both of which apply a score from the ... See full document

... a unified framework was adopted to decode with different models and ease the implementation of decoding algorithms. Moreover, some useful utilities were distributed with the toolkit, such as: a discriminative reordering ... See full document

... This postorder traversal has several advantages. A treelet is only processed once all of its immedi- ate supertreelets have been computed, which is op- timal to reduce the cost of the ⊗ operation. The way the procedure ... See full document

... We carry out experiment on Chinese-English NIST evaluation tasks. We use FBIS corpus (250K sentence pairs) as training data with the source side parsed by a modified Charniak parser (Charniak 2000) which can output a ... See full document

... Table 1 shows the BLEU scores of mixed-cased and detokenized translations of different systems. We see that all the binarization methods improve the baseline system that does not apply any binarization algorithm. ... See full document

... As is generally acknowledged, word order dif- ferences are not entirely arbitrary. By and large they follow syntactic structure. An analysis of word-aligned French-English data by Fox (2002) showed that word alignment ... See full document
