| Outline of Final Research Achievements |
To develop a semi-automatic content analysis of human values appearing in newspaper editorials related to the nuclear power plant disaster, we divided the content analysis into three stages and proposed to use a classifier for each stage. Manual coding results were used to train the classifiers for the content analysis. We developed a method for efficiently improving the quality of the manual coding results. We also developed a method for selecting training data for classifiers efficiently. Finally, we studied methods to find new human value categories.

| Academic Significance and Societal Importance of the Research Achievements |
質的な研究手法である内容分析に対して、内容分析の質を極力落とさずに、できるだけ自動的な手法を取り入れ、人の労力を減らすためのアプローチ、手法の開発・提案に取り組んだ。主に、内容分析を3ステージに分け、それぞれに分類器を用いる半自動化の方法の提案、分類器に必要な質の高いデータを効率的に構築する手法、分類器が効率的に学習するための学習用データの選択手法等を開発することで、内容分析の効率化に貢献したといえる。
