| Research Abstract |
This research project developed a method for automatically acquiring knowledge for case alternation between the passive and active voices in Japanese. By leveraging several linguistic constraints on alternation patterns and lexical case frames obtained from a large Web corpus, our method aligns an inputted case frame in the passive voice to a corresponding case frame in the active voice and finds an alignment between their cases. In addition, we released an anaphora and ellipsis resolution system as an extension of Japanese dependency and case structure analyzer KNP.
