Knowledge Graph-based Retrieval-Augmented Generation for Schema Matching

A proposed model for schema matching using knowledge graphs and retrieval-augmented generation.

The authors propose a Knowledge Graph-based Retrieval-Augmented Generation model (KG-RAG4SM) to address semantic ambiguities in schema matching. The model introduces novel vector-based, graph traversal-based, and query-based graph retrievals. Experimental results show that KG-RAG4SM outperforms state-of-the-art methods in terms of precision and F1 score on various datasets.
