bishop_train.jsonl/bishop_test.jsonl— the loadable split (referenced by the dataset viewer).bishop_train_clean.jsonl— the full cleaned corpus before splitting (train ∪ test).clean_stats.json— per-source record/token counts (raw vs cleaned).quality_eval.json— per-source quality heuristics (token size, explanation/chess density, %English).bishop_counts.json— the "bishop" filter counts per source that defined the selection.split_manifest.json— split parameters, per-source counts, and benchmark-game coverage.
Selection & cleaning
- Records mentioning "bishop" ≥ 2×, drawn from the 3 highest-quality sources (lichess studies +
gameknot games in
annotated_pgn, and chessstackexchangeQ&A), deduped (the gameknot folder is a subset ofannotated_pgn). - Cleaning stripped admin PGN headers / URLs / tooling / promo, folded real master-game headers into a compact caption, kept setup FENs / study titles / diagram labels / analysis prose, and converted NAG codes to symbols.
- Verified by 3 adversarial-review passes and 2 over-removal audits (final residual-noise scan = 0; move content fully preserved).
