Researchers have developed a new framework called Explore-on-Graph (XoG) designed to improve question answering over incomplete knowledge graphs. XoG addresses the issue of missing facts in knowledge graphs by learning to recover reasoning paths from the graph structure itself, rather than relying on the LLM to generate potentially hallucinated information. The framework integrates entity-relation statistics with KG embeddings to identify plausible missing entities and uses the LLM as a semantic selector. Experiments on various benchmarks demonstrate XoG's effectiveness, showing it remains competitive on complete graphs and outperforms other methods when faced with missing data, while also reducing LLM token consumption.
