명사 빈도의 변화, 사회적 관심의 트렌드: 물결 21 코퍼스[2000-2009]

초록

Words reflect man’s current interest because man talks about things which is important to him and others around him. Words in the newspapers are more so because newspaper articles report and discuss the current (often yesterday’s) things of social interests, which constitute social trends. In this paper, we investigate nouns in the Trends 21 Corpus[2000-2009], a large collection of all the texts in the four major Korean daily newspapers published from 2000 through 2009 (size: c. 400 million words). First, we discuss the importance of nouns in newspaper texts and the meaning of usage frequencies as showing social interests and trends. Then, we analyze words of most rapid increase and words of most rapid decrease in frequencies. As research methods, we use Mann-Kendall trends tests and regression analysis. Finally, we briefly compare our approach with other recent frequency-based trend analyses including Daum Communications’ and Google’s.
