An Analysis of Register Information of Japanese Language Described in Dictionaries and Appearing in the Balanced Corpus of Contemporary Written Japanese

对日语的语域信息进行了详细的描述。首先，我们回顾了现有的日语和英语词典中对语域信息的描述。在此基础上，我们选取了一些老字号词语，利用日语常用词典进行了对比研究，并利用《现代日语书面日语平衡语料库》进行了分析，提出了一套较为详细的词汇描写方法。我们还研究了日语学习者和年轻的以日语为母语的人容易滥用的语域信息，并发现了一些在书面文件中使用口语风格的典型例子。我们表明，我们提出的描述方法可以用来避免、检测和纠正这种误用情况。

We discuss detailed description for register information of Japanese language. First, we review descriptions of register information in existing Japanese and English dictionaries. We then focus on some old-fashion words, and perform a comparative study using widely-used Japanese dictionaries and an analysis using the Balanced Corpus of Contemporary Written Japanese, to propose a method of its detailed lexical description. We also study register information that tends to be misused by Japanese learners and young native Japanese speakers, and find some typical examples where spoken styles are used in written documents. We show that our proposed description method can be utilized to avoid, detect, and correct such misuse cases.
