Each record is an auto-verifiable supervised pair: the `input` is unpunctuated hanzi, the `output` is the same text with gold punctuation. ```json {"task":"punctuate_classical_chinese", "instruction":"为下面的文言文断句并加上标点。", "input":"韩信之后也当淮阴钟室难作之时有客匿其孤求抚于萧相国…", "output":"韩信之后也。当淮阴钟室难作之时,有客匿其孤,求抚于萧相国…", "title":"坚瓠集","dynasty":"清","author":"褚人获","canon":"子藏"} ``` ## What you get (full set) - **5,314,004 supervised pairs** across 10 canons of classical Chinese (history, philosophy, poetry, religion, medicine, arts), spanning the 汉–清 dynasties. - Train / validation / test splits, plus an **81,929-pair held-out evaluation set** (contamination-controlled; licensed separately). - Per-work attribution: `title`, `dynasty`, `author`, `canon`. - Parquet (zstd) shards, one per canon. See `CONTENTS.md` for the full breakdown. ## Why it is high quality - **Auto-verifiable labels.** Each `input` is produced by *stripping* an authoritative edition's punctuation from the `output`, so `input == output` minus punctuation by construction (QC: 0 mismatches). No second LLM touches the labels — clean provenance, no synthetic distillation. - **Leakage-controlled.** Split **by work**, not by passage. Mojibake-rejected, punctuation-density filtered, globally de-duplicated; cross-canon duplicate works collapsed to one canonical copy. ## This repo (listing) Public **200-record sample** only (`sample.jsonl`). The full corpus, per-canon shards, and held-out eval are delivered on purchase. Payment and delivery are handled off-platform — **email `wangeksy@gmail.com`**. ## Provenance & rights Base texts are public-domain classical works (汉–清). An editorial-rights-clean, **independently re-punctuated** tier (labels produced from the public-domain text without any third-party 整理本) is available on request for redistribution use cases. ## Related Companion commercial datasets from the same corpus: **校勘 Variant Collation** (aligned recensions) and an expert-graded **文言→白话 Translation + QA evaluation** set.
