Challenge: Large language models (LLMs) are susceptible to generating hallucinated content and often encompass factually inaccurate information.
Approach: They propose a framework that leverages knowledge graphs to address the limitations of Large Language Models (LLMs) they identify and decompose required knowledge triples that are not present in the KG, enriching them and aligning updates with real-world demands.
Outcome: The proposed framework reduces hallucinations and increases factual accuracy in QA scenarios while retaining the same quality of knowledge.
