Abstract

fetched live from OpenAlex

Increasingly, modern system design is concerned with the integration of legacy systems and data. Consequently, data integration is an important step in many system design projects and also a prerequisite to data warehousing, data mining, and analytics. The central step in data integration is the identification of similar elements in multiple data sources. In this paper, we describe an application of principles of similarity based in cognitive psychology, specifically the theory of Similarity as Interactive Activation and Mapping (SIAM) to the problem of database schema matching. In a field that has been dominated by a multitude of ad-hoc algorithms, cognitive principles can establish an appropriate theoretical basis. The results of this paper show initial success in matching applications and point towards future research.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
