| Abstract | In the ``Sandglass'' MT architecture, we identify the class ofmonosemous Japanese functional expressions and utilize it in the task oftranslating Japanese functional expressions into English. We employ thesemantic equivalence classes of a recently compiled large scalehierarchical lexicon of Japanese functional expressions. We then studywhether functional expressions within a class can be translated into asingle canonical English expression. Based on the results ofidentifying monosemous semantic equivalence classes, this paper studieshow to extract rules for translating functional expressions in Japanesepatent documents into English. In this study, we use about 1.8MJapanese-English parallel sentences automatically extracted fromJapanese-English patent families, which are distributed through thePatent Translation Task at the NTCIR-7 Workshop. Then, as a toolkit ofa phrase-based SMT (Statistical Machine Translation) model, Moses isapplied and Japanese-English translation pairs are obtained in the formof a phrase translation table. Finally, we extract translation pairs ofJapanese functional expressions from the phrase translation table.Through this study, we found that most of the semantic equivalenceclasses judged as monosemous based on manual translation into Englishhave only one translation rules even in the patent domain. |
