Semantic Study on the Dynamic Organization of Perspectives and Contextual Parameters

对话通常有一个角度，可以从这个角度来评估话语的内容。然而，观点并不总是一致的。即使在对单一事件的讨论中，观点也会发生变化。在本研究中，我根据日本的数据表明，观点的转变是通过改变语境参数以及态度持有者的论点转移来决定的，即特别是话语主体的转移。

Conversations usually have a perspective with respect to which the content of the discourse can be evaluated. However, the perspective is not always uniform. Perspectives can shift even during a discourse about a single event. In this study, I show that the perspective shifts are determined by shifting the contextual parameter along with the attitude holder argument shift, i.e. specially subject of utterance shift, with reference to Japanese data.
