Adaptive Text2GQL: Integrating Structural Twig Linking and Evolutionary In-Context Learning (2026.acl-long)
Copied to clipboard
| Challenge: | Existing approaches struggle with structural hallucinations and lack adaptability in cold-start scenarios. |
| Approach: | They propose a unified, training-free framework for translating natural language into Graph Query Languages. |
| Outcome: | The proposed framework improves accuracy and executability over baselines in Graph2GQLs. |
Hierarchical Visual Agent: Managing Contexts in Joint Image-Text Space for Advanced Chart Reasoning (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing MLLMs are strong at understanding single plots, but struggle with multi-step reasoning . Existing approaches to manage context in chart reasoning include text-based chain-of-thought prompting . |
| Approach: | They propose a hierarchical visual agent framework that iteratively constructs a working context in an image–text space. |
| Outcome: | The proposed framework improves on strong multimodal baselines. |
