TIME SERIES ANALYSIS OF THE TREND OF NEWSPAPER REPORTS ABOUT PUBLIC WORKS

Abstract

In this study, I have analyzed the trend of the time series of newspaper reports. In Japan, it is commonly said that media reports have to be critical of public works. Besides, such reports can affect critically to national policy as well as the impression people have. Due to those backgrounds, we intended to get the basic knowledge about the tendency of these reports. Therefore, we examined the secular change in the frequency of some of the “words” which related to public works with a keen consideration of the historical background about it. As a result, more negative press seems to have been made in accordance with the increase of expenditures on public works.
