Researchers have developed SemStruct, a new framework for schema matching that combines the semantic understanding of pre-trained language models (PLMs) with the structural analysis capabilities of Graph Neural Networks (GNNs). This approach models tabular data as a graph, allowing it to capture crucial row-level context that is often lost when tables are treated as simple text sequences. SemStruct achieves state-of-the-art performance on benchmarks, even outperforming methods that fine-tune large language models, while keeping the PLM frozen and training only a lightweight structural encoder.
