A comprehensive framework for predicting public opinion by tracking multi-informational dynamics

In the digital landscape, trivial rumors can spark significant online reactions. Accurate prediction of public opinion is important for crisis management, misinformation mitigation, and fostering public trust. However, existing methods often fail to thoroughly investigate multiple informational factors and their timely interactions, thereby limiting their efficacy in analyzing public opinion.
To address this gap, a research team led by Mintao Sun published their new research on 15 August 2024 in Frontiers of Computer Science co-published by Higher Education Press and Springer Nature.
The team proposed a novel framework, MIPOTracker, designed to predict public opinion crises by tracking multiple information factors.
This study proposes a novel multi-informational public opinion crisis prediction frame MIPOTracker, which is shown in the figure. It uses Latent Dirichlet Allocation (LDA) and a Transformer-based language model to analyze topic aggregation degree (TAD) and negative emotions proportion (NEP) in public opinion. The public opinion crisis model MIPOTracker is formed by integrating TAD and NEP with discussion heat (H) into a time-series model. An external gating mechanism is introduced to enhance it by controlling the influence of extraneous factors.
This study introduced the MIPOTracker model for predicting public opinion crises. It innovatively includes multiple pieces of information like themes, emotions, and popularity, improving the model's representation of public opinion events. The experiment results confirm that multi-informational factors significantly influence public opinion development. Predicting public opinion trends is complex and involves factors like event types, which we aim to explore in future research.
