Abstract
This paper proposes a method for predicting continuous emotion dimensions, namely Valence and Arousal, from text by combining affective intermediate training with multi-task learning. The proposed approach consists of two training phases: an intermediate pre-training phase using external emotion datasets, followed by a multi-task learning phase using task-specific data. RoBERTa-large is employed as the backbone model, and independent regression heads are introduced for each subtask. Experimental results show that the proposed method achieves Pearson correlation coefficients of 0.68 for Valence and 0.45 for Arousal on Subtask 1, demonstrating stable performance, particularly in capturing inter-user differences in emotional expression.- Anthology ID:
