A research paper details the UKP_Psycontrol system's success in SemEval-2026 Task 2, which focuses on modeling affective dynamics in user-generated text. The system employed a combination of large language model (LLM) prompting, a Maximum Entropy model, and a neural regression model. Notably, the LLMs proved effective at identifying current affective states, while recent numerical state trajectories were better predictors of short-term affective changes than textual content alone. The UKP_Psycontrol system achieved first place in both Subtask 1 and Subtask 2A of the competition. AI
