| Outline of Final Research Achievements |
We developed a method of semantic analysis, especially for predicate argument structure on spoken language. The proposed method considers backward reference, a characteristic of spoken language to robustly process spoken languages. We developed a predicate argument structure analyzer that does not use dependency information of words to verify the influence of lack of dependency information, which is difficult to extract from spoken sentences. We used pointwise method to build the system to analyze sentences, even if it is unfinished sentence, by introducing backward reference label. This architecture make it possible to predict not only structure of spoken contents by the user but also existences of unseen future content words. We also developed a dialogue corpus to confirm the phenomena of backward reference.
