arXiv:2606. 05724v1 Announce Type: cross Abstract: Long-form narrative QA requires reasoning over evolving story worlds rather than isolated passages: answers may depend on earlier goals, changing character states, social relations, causal triggers, temporal position, and later consequences.

GraphLit introduces Dynamic Heterogeneous Character Networks (DHCNs) that structure long novels into temporally localized graphs aligning characters with their textual contexts. Using a masked graph autoencoder, GraphLit learns rich literary representations and outperforms text-only, graph-only, and prior hybrid baselines on 12 character-related tasks. Ablation studies show that grounding characters in context is the primary performance driver, while narrative order and character relationships offer task-dependent gains, and the framework is applied to analyze the link between narrative non-linearity and dynamic social features.
