It is said that the result of the general election 2005 was greatly affected by mass media's news coverage. In this paper I compare the editorials of the three major newspapers in Japan: Yomiuri Shimbun, Asahi Shimbun and Mainichi Shimbun. Co-occurrence networks and centering resonance analysis are used to examine the features of the texts. Relevance, consistency and uniqueness are the most important elements that the media texts should have in order to be convincing with the readers. The elements are shown clearly and visually with some network analysis methods.
