Context-Aware Sentiment Forecasting via LLM-based Multi-Perspective Role-Playing Agents

AbstractUser sentiment on social media reveals underlying social trends, crises, and needs. Researchers have analyzed users’ past messages to track the evolution of sentiments and reconstruct sentiment dynamics. However, predicting the imminent sentiment response of users to ongoing events remains understudied. In this paper, we address the problem of sentiment forecasting on social media to predict users’ future sentiment based on event developments. We extract sentiment-related features to enhance modeling and propose a multi-perspective role-playing framework to simulate human response processes. Our preliminary results show significant improvements in sentiment forecasting at both microscopic and macroscopic levels.
