Research of Knowledge-Enhanced Large Language Model Based on Knowledge Graph

The rapid development and wide application of Knowledge Graph(KG) and Large Language Model(LLM) have demonstrated strong basic capabilities of artificial intelligence. In the last two years, related research has explored the combination of KG and LLM to improve the model's ability in text understanding and inference. In view of this kind of research, the basic knowledge of KG enhancing LLM is systematically introduced, and how KG enhances LLM from the perspective of functional realization is analyzed, and the existing research results of KG enhancing LLM is also summarized, which provides reference for further research on LLM enhanced by KG.
