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

Version 1.4.0: 5-chunk-depth audit of the top-20 largest-by-file-count named author directories surfaced 4 further misfiled files (aristotle/metaphysics.txt actually Bacon's Advancement of Learning; schopenhauer/vol_2/vol_3 actually Burton's Arabian Nights + French magazine; william_james/principles_of_psychology_vol_2 actually a Pasteur biography) that the v1.2.0 and v1.3.0 2-chunk depths missed. Corpus reduced from 952 → 948 texts; named authors unchanged at 123 (all 3 affected dirs retained coverage). See ERRATUM_v1.4.0.md for the full quarantine list and cumulative audit totals. PhiloKG is a knowledge graph of classical philosophical discourse comprising over 2.36 million triples and 200,000 entities extracted from 948 texts by 123 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).
