rosetta-ko-law-synth-cpt

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).

Law Suite

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

repo	format
`rosetta-ko-law-synth-cpt` (this repo)	continued-pretraining corpus (plain `text`)
`rosetta-ko-law-synth-sft`	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

{"text": "...", "source": "...", "license": "...", "url": "...",

text — cleaned Korean source-unit body (continued-pretraining input)
source / url / accessed — provenance of the public-data unit
license — upstream license of the source unit
meta — domain metadata (free-form object)
