Graph-Enhanced Prompt Tuning for Evidence-Grounded HFACS Classification in Power-System Safety

Power-system safety is fundamental to protecting lives and ensuring reliable grid operation. Yet, hierarchical text classification (HTC) methods struggle with domain-dense accident narratives that require cross-sentence reasoning, often yielding limited fine-grained recognition, inconsistent label p...
