Verbalizing LightGCN: Direct Learning of Textual Representations from User-Item Interaction Graph via LLMs

VerbaLightGCN is a novel LLM-based recommendation framework that integrates the semantic understanding of LLMs with user-item interaction modeling and replaces numerical embedding computations with a Chain-of-Thought prompting mechanism, which enables LLMs to simulate the LightGCN aggregation process through natural la...
