Enabling Discriminative Reasoning in LLMs for Legal Judgment Prediction[Paper]

Released Resources

• 🤗The Huggingface model: Based on Qwen2-7B, we trained a model using the CAIL2018 dataset. Qwen2-7B-CAIL2018-step-8765
• The training trajectories: We release the 80,141 training trajectories of the CAIL2018 dataset in this link

Supported Prompts

❗️Note: Our released model needs the Qwen chat_template to conduct correct generation.

We support the following four prompts to enable reasoning. You should use the same input format and prompt to achieve the best performance.

Prompt 1: ADAPT Reasoning

case_input = f"案件描述：{description}\n被告人姓名：{defendant_name}"
prompt = "请你采用ADAPT框架分析以上案件中该被告人可能被判处的罪名、适用法条和刑期"
model_input_str = '\n'.join(case_input, prompt)

Prompt 2: Ask

case_input = f"案件描述：{description}\n被告人姓名：{defendant_name}"
prompt = "请你用法律理论分析以上案件中该被告人在行为主体，起因、行为和结果，行为对象，犯罪主观四个方面的信息"
model_input_str = '\n'.join(case_input, prompt)

Prompt 3: Article

case_input = f"案件描述：{description}\n被告人姓名：{defendant_name}"
prompt = "请你依次列出以上案件中被告人适用的法条具体内容，以及适用该法条的原因"
model_input_str = '\n'.join(case_input, prompt)

Prompt 4: Sentencing factors

case_input = f"案件描述：{description}\n被告人姓名：{defendant_name}\n罪名：{crimes}" # e.g., 污染环境罪
prompt = "请你分析以上案件中的量刑区间和量刑因素，并给出最后的量刑预测结果"
model_input_str = '\n'.join(case_input, prompt)
