In the aspect of big data research, LG Economic Research Institute & Media Daum (2010) presents Korean society's concerns in 2010 (August 2009 - July 2010) based on the ranking of news articles and search terms and market statistics. This is based on data which would reflect Korean social popularity. The purpose of this paper is to examine how changes in word frequencies over time in newspaper corpora reflect social concerns analyzed by LG Economic Research Institute & Media Daum (2010). We investigate frequency trend charts of words related to social concerns from the Trend 21 corpus composed of Chosun Ilbo, Dong-A Ilbo, Joongang Ilbo, and Hankyoreh newspaper articles for 14 years from 2000 to 2013. This paper shows advantages of using newspaper corpora in linguistics, humanities and social sciences, and big data research, and suggests the importance of observing changes in word frequencies over time for exploring social concerns and trends.
