| Challenge: | Large language models (LLMs) are strong reasoners but still hallucinate and make unreliable decisions on knowledge-intensive questions. |
| Approach: | They propose a pipeline that turns LLM into executable tool supervision without manual trace labeling. |
| Outcome: | The proposed model improves over a reproduced prompting baseline by +22.5/+16.2 points . it is based on a Graph Explorer pipeline that turns SPARQL into executable tool supervision without manual trace labeling. |
