BCCWJのブログレジスタ-における話し言葉と書き言葉の諸相

Abstract

In recent years, Japanese studies using the web and corpus have been increasing. Balanced Corpus of Contemporary Written Japanese (BCCWJ), constructed by National Institute for Japanese Language and Linguistics in 2011, is one of the most frequently used corpora when studying written Japanese. BCCWJ has 13 sub‐corpora. However, among the 13 sub‐corpora, there are many objections to the positioning of “blogs” and “record of Diet proceedings” as written Japanese. The purpose of this paper is to clarify the position of blogs as corpus for spoken and written Japanese by analyzing the frequency of spoken and written Japanese in “blogs”. In the analysis, the contents of the blog will be classified into 14 genres. According to the analysis results, blogs use not only written Japanese but also spoken Japanese, and the usage rate of spoken Japanese is higher than that of written Japanese. However, the usage rates of spoken and written Japanese vary greatly depending on the words used and on the genre of blogs. This paper argues that blogs require careful attention when used as a corpus of written Japanese and when interpreting the results of analysis.
