An Intelligent Predictive Fairness Model for Analyzing Law Cases with Feature Engineering
This study introduces an AI-powered model, named the Legal Judgment Prediction Ensemble (LJPE), which is designed to predict legal case outcomes by leveraging historical judicial data. By using natural language processing (NLP) techniques, feature engineering, and a complex two-level stacking ensemble, the LJPE model has better predictive accuracy at 94.68% compared to modern legal language and conventional machine learning models. Moreover, the findings underline the predictive strength of textual features obtained from case facts, vote margins, and legal-specific features. This study offers a solid technical solution for predicting legal judgments for the responsible use of the model, helping to create a more efficient, transparent, and fair legal system.
Executive Impact Summary
The LJPE model represents a significant leap forward in legal AI, offering unparalleled accuracy and robustness in predicting case outcomes. Its ability to integrate advanced NLP with domain-specific legal features sets a new benchmark for efficiency and fairness in judicial processes.
