Outline of Final Research Achievements

As a result of this research, we collected approximately 1.6 million posts on social media related to youth issues. By analyzing the collected content, we were able to identify regional terms that can serve as reference points for the relevant prefectural police departments. Additionally, by analyzing the trends of these terms, we identified the main topics related to sexual exploitation. Furthermore, by tracking the targets of the awareness-raising activities conducted by the police and cybercrime prevention volunteer groups, we determined the time required for content removal. We also developed a prototype web system for sharing the collected information among the police and cybercrime prevention volunteer groups, and through actual operation, we verified its usefulness for information sharing.

Academic Significance and Societal Importance of the Research Achievements

本研究は，青少年が違法有害情報を閲覧するリスクを軽減するための取り組みに必要となる「有害情報の自動収集の仕組みの構築」，「収集した内容の分析による地域性や内容の分析」，「情報共有システムとしての動作検証」を行った．これにより，警察やサイバー防犯ボランティア団体が違法有害情報対策を容易に行うためのシステムによる補助の可能性を示すことができた．
