Research Abstract

In this project, we developed an extraction method for accurate and long-distance phrase reordering rules that are lexicalized by function words such as prepositions. Since patterns of function words determine the structure of a sentence, the rules can correctly reorder phrases on the basis of the structure. In Japanese-English translation experiments, we improved the performance of our translation system using the proposed rule set.
