GROKE: Vision-Free Navigation Instruction Evaluation via Graph Reasoning on OpenStreetMap (2026.acl-long)
Copied to clipboard
| Challenge: | Existing evaluation metrics for navigation instructions are limited by licensing constraints and computational costs. |
| Approach: | They propose a vision-free training-free hierarchical LLM-based framework for evaluating navigation instructions using OpenStreetMap data. |
| Outcome: | The proposed framework reduces navigation error by 68.5% compared to baselines on the Map2Seq dataset. |
