SemFD data snapshots: Certifying Functional Dependencies over Latent Entity Identity

Snapshots of the public input files used by the experiments of the paper Certifying Functional Dependencies over Latent Entity Identity (Wookey Lee, Suan Lee). Code, results and the technical report: https://github.com/suanlab/SemFD. Upstream sources change over time, so this record keeps the exact files whose sha256 hashes are listed in the code repository (results/icde27/DATA_SNAPSHOTS.txt). Each file is gzip-compressed on its own; verify.sh unpacks them into ./data/ and checks the hashes. The files keep their original licences (mixed, all open): GeoNames (cities15000, cities500, admin1CodesASCII, countryInfo, alternateNamesV2; retrieved 2026-10-15/20): CC BY 4.0.
