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

Version 1.5.0: exhaustive 5-chunk-depth audit of the 32 non-top-20 ≥5-file named-author directories surfaced 6 further misfiled files (shakespeare/merchant_of_venice = Much Ado About Nothing; shakespeare/twelfth_night = A Midsummer Night's Dream; buddhist/questions_of_king_milinda_vol1 = Victorian blank-verse bible drama; buddhist/vinaya_texts_vol2 = Burton's Arabian Nights Vol. 2; bergson/matter_and_memory = Albert B. Paine's novel Peanut; twain/adventures_of_huckleberry_finn = byte-identical duplicate of Joyce's Ulysses) that the v1.2.0-v1.4.0 prior audits had missed. Corpus reduced from 948 → 942 texts; named authors unchanged at 123. See ERRATUM_v1.5.0.md for the full quarantine list and cumulative audit totals (60 files / 25,631 chunks / 97,683 triples removed across v1.1.1 → v1.5.0). PhiloKG is a knowledge graph of classical philosophical discourse comprising over 2.35 million triples and 200,000 entities extracted from 942 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).
