Understanding Quantitative Reasoning in LJP
Legal Judgment Prediction (LJP) aims to forecast judicial outcomes based on case facts. While existing models perform well in law article and charge prediction, they often struggle with prison term prediction due to a lack of sophisticated quantitative reasoning. This paper introduces a novel approach that leverages monetary features and legal quantitative reasoning to better quantify crime severity.
Our Proposed QR-LJP Framework
The QR-LJP model integrates legal reasoning into the prediction process. It employs a curated Large Language Model (LLM) to extract monetary values and calculate the total crime amount, serving as a quantitative measure of crime severity. This measure is then used for judgment predictions, aligning with legal statutes.
Key components include a TCA calculation module (FineChatGLM), a pre-trained number encoder (DICE), and a judgment prediction module that incorporates cross-task dependencies and label semantics.
Significant Performance Gains
Experimental results on the CAIL-2018 dataset demonstrate that QR-LJP significantly outperforms current SOTA methods, especially in prison term prediction, achieving a 4.17% improvement in Macro-F1 scores. This highlights the effectiveness of incorporating legal quantitative reasoning. Moreover, applying our quantitative reasoning strategy to existing SOTA methods also yields significant improvements, proving its universal applicability.
