Linguistic Signatures for Enhanced Emotion Detection
arXiv:2603.20222v1 Announce Type: new Abstract: Emotion detection is a central problem in NLP, with recent progress driven by transformer-based models trained on established datasets. However, little is known about the linguistic regularities that characterize how emotions are expressed across different corpora and labels. This study examines whether linguistic features can serve as reliable interpretable signals for emotion recognition in text. We extract emotion-specific linguistic signatures from 13 English datasets and evaluate how incorporating these features into transformer models impacts performance. Our RoBERTa-based models enriched with high level linguistic features achieve consistent performance gains of up to +2.4 macro F1 on the GoEmotions benchmark, showing that explicit lexical cues can complement neural representations and improve robustness in predicting emotion categories.

Executive Summary
This study investigates the potential of linguistic features as interpretable signals for emotion recognition in text. By extracting emotion-specific linguistic signatures from 13 English datasets, the researchers demonstrate that incorporating these features into transformer models can achieve consistent performance gains of up to +2.4 macro F1 on the GoEmotions benchmark. The findings suggest that explicit lexical cues can complement neural representations and improve robustness in predicting emotion categories. The study's results have significant implications for the development of more accurate and interpretable emotion detection systems, which can be applied in various fields, including psychology, marketing, and customer service. However, the study's reliance on existing datasets and the lack of exploration of linguistic features in other languages are notable limitations.
Key Points
- ▸ Linguistic features can serve as reliable interpretable signals for emotion recognition in text.
- ▸ Incorporating linguistic features into transformer models can achieve consistent performance gains.
