Studies on Grammar and Usage in Japanese Daily Conversation based on Corpora

本研究的目的是在日语语料库的基础上，准确描述日语日常会话中的语法和用法的各个方面。在三年的研究中，我们描述了结尾助词ne、yo、yo的功能、格助词o和ga的移位条件以及ni和o的移位条件；我们报告了情态项mitaida/yooda在日常会话中的使用情况，以及被动句和使役句在日常会话中的实际使用情况；我们还研究了体态表达~te shimau在日常对话和报纸中的使用差异。本研究还对日语学习者使用连接表达noakara的情况进行了调查。对基本由标准日语进行的会话中使用的地区方言进行了一些有趣的观察。对日语日常会话和报纸日语中的搭配进行了研究，得出了一些有趣的结果。语料库在语言研究中的应用才刚刚起步，尤其是在会话语言研究中。这意味着有必要建立更多的日语会话语料库。我们研究中使用的美的语料库将在不久的将来通过国家语言研究所的服务器提供给研究人员，这是我们研究的贡献之一。
