From Affect Prediction to Affect Forecasting: Evidence for Distinct Information Sources in Longitudinal Text
A new research paper proposes the Trait-State Affective Prediction (TSAP) framework and its temporal extension E-TSAP to distinguish between predicting current emotional states and forecasting future affective changes from longitudinal text. The study found that while textual semantics are effective for predicting current affect, prior numeric trajectory dynamics are better indicators for forecasting future emotional shifts. The proposed Affective Change Forecaster Hybrid (ACF-Hybrid) model, utilizing these numeric trajectories, achieved significantly higher forecasting accuracy than text-based models. AI
IMPACT This research highlights the distinct information sources required for predicting current emotions versus forecasting future affective changes in text, suggesting improvements for AI models in understanding and predicting human emotional dynamics.
