Geospatial metadata lifts cross-disciplinary dataset connection rate to 63.2%
Authors self-report that geospatial metadata enrichment raised cross-disciplinary dataset connection rate from 58.5% to 63.2%, with linking power about twice that of keyword paths.

After small language models were fine-tuned for geospatial metadata enrichment, the self-reported cross-disciplinary metadata connection rate rose from 58.5% to 63.2%; in a metadata knowledge graph, datasets are about twice as likely to be linked across scientific disciplines through shared geospatial metadata as through keyword paths.
Previously, in an analysis of Harvard Dataverse, the authors report that only 0.3% of research datasets contained geospatial bounding boxes, so cross-disciplinary connections relied mainly on keyword paths.
Ebanks and Jain measured this change: geospatial metadata enrichment raised the connection rate from 58.5% to 63.2%, with linking power about twice that of keyword paths.
