| Outline of Research at the Start |
This research project aims to reveal ideological bias of conservative news media that would contribute to regional instability through a large-scale content analysis of newspaper articles and survey experiments in Japan and Israel. We will analyze Japanese and Hebrew newspaper articles on North Korea and Iran over years, and conduct survey experiments in both countries based on findings of the content analysis. We will also develop a new quantitative approach to Asian-language texts, and strengthen academic ties between Japan and Israel through this collaboration.
|
| Outline of Final Research Achievements |
In this research project, we organized an international conference to initiate the rapid development of quantitative text analysis in Japan. We enabled young scholars to conduct innovative research in many social science fields through our methodological research on quantitative text analysis of Asian languages. Through content analysis and survey experiment in Japan and Israel, we revealed that the conservative media tend to overemphasize security threat and that media reports about security threats alone can trigger the rally around the flag effect even without actual military actions.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の貢献は、これまで困難だと考えられてきたアジア言語の文書の統計的な分析をノートパソコンだけで容易に行えるようにしたことである。また、本研究から生み出された手法は、社会科学のみならずデータ科学や産業界におけるデータ分析でも利用できるものである。研究成果と関連するソフトウェアはすべてオープンソースで公開し、広く利用を促している。
