Title: Format-Constraint Coupling in Knowledge Graph Construction from Statistical Tables

Abstract:
arXiv:2605.21974v1 Announce Type: new Abstract: An extraction schema should not reduce knowledge graph fidelity. On statistical CSV, however, it can. We study country-by-year time-series matrices, a common layout on open-data portals. In this setting, serialization format and schema constraints interact super-additively. Their joint effect exceeds the sum of independent effects by up to +1.180 (2x2 factorial, 6 datasets). Bootstrap 95% CIs are strictly positive on 4/6 datasets, with strongest ev
