## AI System for HPV Vaccination in Japan A team of researchers has developed an AI agent system to improve communication and information regarding human papillomavirus (HPV) vaccination in Japan. The system is designed to provide accurate information and combat misinformation, a particularly relevant issue due to the suspension of proactive vaccination recommendations between 2013 and 2021. ## System Architecture The system integrates several key components: * A vector database that collects academic papers, government sources, news media, and social media data. * A chatbot that uses the ReAct architecture to provide relevant and verified answers, drawing on five different knowledge sources. * An automated report generation system with modules for news analysis, research synthesis, social media sentiment analysis, and user interaction pattern identification. ## Performance Evaluation The system's performance was evaluated using a 0-5 scoring scale. The chatbot achieved high average scores in terms of relevance (4.83), correctness (4.90), and reference quality (4.50). The report generation system demonstrated high completeness and correctness, with a reference validity of 5.00 across all evaluated periods. ## Implications and Transferability The study demonstrates the feasibility of an integrated AI agent system for bidirectional HPV vaccination communication. The system architecture is transferable and adaptable to other medical contexts, making it a potentially valuable tool for addressing communication challenges in the healthcare sector.
