From Insights to Influence: Artificial Intelligence (AI) as Tool and Social Actor in Health Communication Research

3. 초록
This talk showcases the evolving role of artificial intelligence (AI) in health communication research through two studies. The first study highlights the application of Large Language Models (LLMs) for classification tasks, specifically examining COVID-19 vaccine-related social media posts. By comparing state-of-the-art LLMs, this research demonstrates their effectiveness in classifying vaccination behaviors, intentions, and information-sharing, with results showing an alignment between online discourse and real-world vaccination trends. The second study shifts focus to relational AI, investigating how AI chatbots act as social actors to promote health behaviors. By assessing the chatbot’s warmth and competence, this study illustrates how relational behaviors foster meaningful human-chatbot relationships and influence physical activity behavior intentions. Together, these studies demonstrate AI’s multifaceted potential to advance health communication research, from capturing behavioral insights to influencing human behaviors.
