Abstract

This paper proposes an effective parsing method for example-based machine translation. In this method, an input string is parsed by the top-down application of linguistic patterns consisting of variables and constituent boundaries. A constituent boundary is expressed by either a functional word or a part-of-speech bigram. When structural ambiguity occurs, the most plausible structure is selected using the total values of distance calculations in the example-based framework. Transfer-Driven Machine Translation (TDMT) achieves efficient and robust translation within the example-based framework by adopting this parsing method. Using bidirectional translation between Japanese and English, the effectiveness of this method in TDMT is also shown.
