Alignment-based reordering for SMT

We present a method for improving word alignment quality for phrase-based statistical machine translation by reordering the source text according to the target word order suggested by an initial word alignment. The reordered text is used to create a second word alignment which can be an improvement of the first alignment, since the word order is more similar. The method requires no other pre-processing such as part-of-speech tagging or parsing. We report improved Bleu scores for English-to-German and English-to-Swedish translation. We also examined the effect on word alignment quality and found that the reordering method increased recall while lowering precision, which partly can explain the improved Bleu scores. A manual evaluation of the translation output was also performed to understand what effect our reordering method has on the translation system. We found that where the system employing reordering differed from the baseline in terms of having more words, or a different word order, this generally led to an improvement in translation quality.

A Pattern Extraction Workbench Combining Multiple Linguistic Levels
Magnus Merkel | Andreas Lange
Proceedings of the Fourth International Conference on Language Resources and Evaluation (LREC’04)

In this paper an interactive pattern extraction workbench, I*Pex, is presented. The workbench comes in a graphical environment and is designed to be used in an incremental and interactive fashion with the user. Patterns can be constructed to work in combination involving specifications on several linguistic levels simultaneously, from the character level using regular expressions, parts of speech and dependency relations to semantic roles. The input text format is based on XCES XML format.
