Translation Disambiguation of Patent Sentences using Case Frames
Shoichi Yokoyama, Masumi Okuyama · 2009
Patent sentences have long, complicated struc-tures, and correctly analyzing and translating such sentences is difficult. We have classified the modified relationships in Japanese patent sentences and constructed an error correcting system for analysis of such sentences. In the present paper, we investigate manually whether the Japanese case frames, which are automatically derived from a web corpus, cor-respond to disambiguated English words. The present study reveals that case frames of verbs originating from active nouns may be useful for disambiguating English verbs, whereas the case frames of traditional Japanese verbs are problematic.
