GDC-SM is a schema matching evaluation benchmark based on a real data harmonization scenario that is common in biomedical research: pooling datasets from multiple studies to increase the number of pat...

Data harmonization is an essential task that entails integrating datasets from diverse sources. Despite years of research in this area, it remains a time-consuming and challenging task due to schema m...

Abstract We prove a tight upper bound on the variance of the priority sampling method (aka sequential Poisson sampling). Our proof is significantly shorter and simpler than the original proof given by...

Recent advances in language models opened new opportunities to address complex schema matching tasks. Schema matching approaches have been proposed that demonstrate the usefulness of language models, ...

Deep-learning typically does not outperform tree-based models on tabular data. Often this may be explained by the small size of such datasets. For image…
