GraphLit: Learning Text-Enriched Dynamic Character Network Representations for Literary Study

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.

Critic's Eye: Review-Grounded Graph Reasoning for Long-Form Motif Discovery

The paper introduces Critic's Eye, a method for computational motif discovery that models a play as a heterogeneous Narrative Topology Graph and performs discriminative inference over global structural evidence. It achieves 84.8% Hit@5 on a benchmark, nearly quadrupling the performance of large foundation models such as Gemini-3-pro-preview. The authors argue that explicit structural priors outperform mere parameter scaling for decoding the complex architecture of long‑form literature.

FRAGMENT: Factorized Graph Representations for Document Generation and Editing via Entity-Aware Transformations

FRAGMENT is a two‑stage generative framework that models documents as typed relational graphs, factorizing the joint distribution into structure and content components. The first stage, the Architect, uses a causally masked Transformer to autoregressively generate graph topology and spatial relations, while the second stage, the Builder, employs a GATv2-based graph attention network to add bounding boxes, text, and visual style attributes. The framework provides explicit likelihood models for anomaly scoring and supports prompt‑conditioned, entity‑aware editing via cross‑attention.

HeTGB: A Comprehensive Benchmark for Heterophilic Text-Attributed Graphs

HeTGB is a new benchmark for heterophilic text‑attributed graphs, consisting of five real‑world datasets where nodes have rich textual descriptions. It allows systematic evaluation of graph neural networks, pre‑trained language models, and co‑training methods on node classification. The benchmark highlights the utility of text attributes, the challenges of heterophilic TAGs, and the limitations of current models.

Bridging Semantics and Structure: A Theoretically Grounded Framework for Link Prediction on TAGs

Bridge-LP is a new framework for link prediction on text‑attributed graphs that combines Graph Neural Networks and Language Models. It introduces three design components: jumping connections for robust language model training, compressed embeddings to encode neighborhood information, and a cache embedding strategy to reduce computational cost. Experiments on nine datasets show that Bridge‑LP outperforms 40 existing models, achieving up to a 43.06% improvement in Mean Reciprocal Rank.

NS-ST-GraphRAG: Neuro-Symbolic Spatio-Temporal GraphRAG for Literary Knowledge Processing

NS-ST-GraphRAG is a neuro‑symbolic spatio‑temporal GraphRAG framework designed to process long‑form literary narratives by integrating ontology‑guided extraction, deterministic constraint checking, dual temporal coordinates, spatial scene attributes, and dynamic sub‑graph retrieval. It selects the appropriate graph state based on the temporal and spatial scope of a query, grounding generated answers in traceable evidence. The authors also introduce Red‑Chamber‑QA, an open multi‑hop question‑answering benchmark for classical Chinese literature, and report that NS‑ST‑GraphRAG outperforms a frozen‑window baseline and a closed‑book model on a held‑out 120‑question split.
