rosetta-ko-law-synth-sft

Korean legal-domain data grounded in national statutes — a cleaned CPT corpus plus source-grounded QA/preference/RLVR sets.

Synthetic data generated with the Qwen3.6-27B teacher model — part of the Rosetta-KO suite for the Rosetta Korean LLM (PoSTMEDIA).

Sibling datasets from the same pipeline (each a separate repo):

repo format
rosetta-ko-law-synth-cpt continued-pretraining corpus (plain text)
rosetta-ko-law-synth-sft (this repo) supervised fine-tuning (user/assistant messages)
rosetta-ko-law-synth-sft-think reasoning SFT (<think> chain-of-thought)
rosetta-ko-law-synth-dpo preference pairs (chosen/rejected)
rosetta-ko-law-synth-rlvr reinforcement-learning-with-verifiable-reward rows

Data Fields

{"id": "...", "source_dataset": "...", "domain": "law",
 "messages": [{"role": "user", "content": "..."},
              {"role": "assistant", "content": "..."}]}
  • id — row-level identifier
  • messages[0] (user) — self-contained Korean prompt
  • messages[1] (assistant) — the answer directly (no reasoning trace)
