Narrative Knowledge Weaver: Narrative-Centric Retrieval-Augmented Reasoning for Long-Form Text Understanding
Summary
Narrative Knowledge Weaver (NKW) is a novel source-grounded framework designed for long-form narrative Question Answering (QA), addressing the limitations of existing retrieval and graph-augmented generation methods that struggle with story-world reasoning. Unlike prior approaches that use isolated chunks or entities, NKW aligns diverse textual evidence, including atomic facts, canonical graph structures, entity profiles, interactions, episodes, and storylines. During query processing, NKW employs text, graph, and narrative tools, combined with post-retrieval reading skills, to assemble evidence and audit actor, scope, polarity, state, and temporal constraints. The framework demonstrates strong performance on screenplay-level story-world QA benchmarks such as STAGE, FairytaleQA, and QuALITY, while maintaining competitiveness on more passage-centered tasks. Analyses confirm its complementary benefits for character, scene, temporal, causal, and narrative-progression reasoning.
Key takeaway
For NLP Engineers developing advanced QA systems for long-form narratives, Narrative Knowledge Weaver (NKW) offers a robust framework to overcome limitations of traditional RAG. You should consider integrating NKW's narrative-centric evidence alignment and multi-tool reasoning to improve performance on complex story-world understanding tasks, especially those requiring deep character, temporal, or causal reasoning. This approach can significantly enhance the accuracy of your systems on screenplay-level content.
Key insights
Narrative Knowledge Weaver (NKW) integrates diverse narrative elements to enable sophisticated story-world reasoning for long-form Question Answering.
Principles
- Narrative QA requires reasoning over evolving story worlds.
- Evidence must encode its function within a story.
- Story understanding needs multi-faceted evidence alignment.
Method
NKW aligns textual evidence, graph structure, entity profiles, interactions, episodes, and storylines. At query time, it uses text, graph, and narrative tools with post-retrieval reading skills to assemble evidence and audit actor, scope, polarity, state, and temporal constraints.
In practice
- Apply NKW for screenplay-level story QA.
- Improve character and temporal reasoning in narratives.
- Enhance causal and narrative progression understanding.
