NarrativeNexus at SemEval-2025 Task 10: Entity Framing and Narrative Extraction using BART

AbstractThis paper presents NarrativeNexus’ participation in SemEval-2025 Task 10 on fine-grained entity framing and narrative extraction. Our approach utilizes BART, a transformer-based encoder-decoder model, fine-tuned for sequence classification and text generation.For Subtask 1, we employed a BART-based sequence classifier to identify and categorize named entities within news articles, mapping them to predefined roles such as protagonists, antagonists, and innocents. In Subtask 3, we leveraged a text-to-text generative approach to generate justifications for dominant narratives.Our methodology included hyperparameter tuning, data augmentation, and ablation studies to assess model components. NarrativeNexus achieved 18th place in Subtask 1 and 10th in Subtask 3 on the English dataset. Our findings highlight the strengths of pre-trained transformers in structured content analysis while identifying areas for future improvements in nuanced entity framing.
