Outline of Final Research Achievements

One of the reasons for the recent progress in the field of machine translation is the rise of statistical machine translation (SMT), which automatically learns translation rules from translated data. However, SMT does not directly consider the reason why it chooses a particular translation, and thus has a tendency not made by rule-based machine translation systems. In this work, we developed methods to automatically learn rules about why a machine translation system should choose a particular translation, and introduce them into SMT systems. Specifically, we developed a translation system based on linguistic knowledge, introduced reasons for translation into this system, created a method to efficiently analyze its output, and developed methods to learn the rules for translation from multilingual data.
