| Challenge: | Existing methods to parse natural language into structured logical expressions have limitations due to paucity of labeled data. |
| Approach: | They propose a scoring model to automatically learn a model-based reward . they also propose introducing a Chinese-PL/FOL dataset to compensate for paucity of labeled data . |
| Outcome: | The proposed model outperforms competitors on several datasets. |
Planning Beyond Text: Graph-based Reasoning for Complex Narrative Generation (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing methods for long-form complex narrative generation struggle to maintain global narrative coherence and logical consistency. |
| Approach: | They propose a framework that performs narrative planning on structural graph representations instead of direct sequential text representations. |
| Outcome: | The proposed model outperforms representative baselines across diverse scenarios. |
