Research Abstract

We have proposed a new framework of term translation. non-productive machine translation. and an efficient algorithm of the execution. We have also developed seven extension techniques for this framework to improve translation performance in the application to Japanese-English term translation. We have implemented a Japanese-English headword search system for the English Wikipedia, which can retrieve English articles from Japanese terms. In the experiments, we have confirmed the effectiveness and high performance of the system.
