PhiloKG: A Multi-Model Knowledge Graph of Classical Philosophical Discourse

Version 1.6.0 (2026-06-10): reproducibility-completion release — graph files unchanged from v1.5.1 (the version evaluated in the paper). Adds the Plato/Seneca 60-chunk benchmark, the 4-model extension raw extractions, the section-6 200-triple verbatim-audit sample with per-judge labels and kappa scripts, the Gemma3 self-consistency 4-pass runs, exact-reproduction scripts for every supplementary statistic (all verified against the published values), the frozen 2026-04-12 tier2 filter snapshot, complete chunk-text companions (no database needed), and the canonical extraction schema. Every quantitative claim in the paper that depends on supplementary data now reproduces from deposit files alone. PhiloKG is a knowledge graph of classical philosophical discourse comprising 2.34 million triples and 200,000 entities extracted from 937 texts by 122 named authors spanning from ancient Greece to the early twentieth century. The resource includes the full knowledge graph in RDF N-Triples format, an annotated Turtle export using RDF 1.2 triple-term reification for per-triple consensus metadata, the RDFS/OWL ontology with a companion SHACL shapes file, per-model benchmark data for the 30-chunk Aeschylus benchmark (6 models) and the 250-chunk cross-vendor benchmark (4 models across Anthropic and Google), the two-tier extraction pipeline source code, and the raw per-judge verdicts from the 500-triple multi-judge precision audit (5 LLM judges across 4 families).
