JevNexus improves schema matching speed and accuracy

By PulseAugur Editorial · [1 sources] ·

Researchers have developed JevNexus, a novel approach to schema matching that frames the task as a series of decisions rather than a simple reranking. This method combines typed pairwise decisions with schema and instance evidence, only invoking a more computationally intensive listwise refinement when evidence is conflicting. JevNexus demonstrated strong performance on benchmark datasets, achieving an MRR of 0.930 and Hits@1 of 0.909, while significantly reducing processing time from over 123 seconds to under 16 seconds compared to the Magneto system. The system's efficiency is maintained by selectively applying listwise refinement to only a small percentage of source columns. AI

IMPACT This research could lead to more efficient and accurate data integration tools by optimizing the use of generative language models in schema matching.

    Correspondences as Decisions: JevNexus for Decision-Centric Schema Matching

    arXiv:2610.09487v1 Announce Type: cross Abstract: Schema matching increasingly uses generative language models to rerank retrieved column candidates, although the underlying task is a bounded correspondence decision. We present JevNexus, which combines typed pairwise decisions wi…
