A Multi-Level Sentiment Analysis Framework for Financial Texts
Yiwei Liu, Junbo Wang, Lei Long, Xin Li, Ruiting Ma, Yuankai Wu, Xuebin Chen International Joint Conference on Artificial Intelligence (IJCAI) 2025 Workshop FinLLM (Oral) International Conference on Machine Learning (ICML) 2025 Workshop NewInML (Poster), arXiv / code / bibtex We propose a novel framework based on PLMs and LLMs, which systematically integrates firm-specific micro-level sentiment, industry-specific meso-level sentiment, and duration-aware smoothing to model the latency and persistence of textual impact. "This work is worth more discussion, and I am open to collaboration." |
