Smart Criminal Judgment Analysis System

An advanced AI-driven research methodology developed for the Sri Lankan Penal Code, leveraging semantic legal extraction and predictive modeling architectures.

System Architecture

🎙️

Resource Finder

Identify relevant laws from plain language case facts.

Uses BERT-based semantic extraction to query the Penal Code and Criminal Procedure Code, clustering legal sections into Prosecution and Defence categories.

Module 01
📄

Argument Builder

Generate structured case profiles from judgment documents.

Performs deep document parsing to extract semantically similar past cases, building balanced 'Prosecution vs Defence' argument reports with strength scores.

Module 02
⚖️

Outcome Predictor

Predict appeal results based on historical patterns.

Employs Bayesian statistical modelling on thousands of historical judgments to calculate probability distributions for outcomes like Acquittal or Sentence Reduction.

Module 03
💬

Semantic Chatbot

Multilingual research aid for real-time legal queries.

An advanced NLP assistant that interprets and answers complex legal questions based on the insights generated by the system's core modules.

Module 04

The Research Problem

The Sri Lankan criminal justice system is currently slowed by a manual review bottleneck. Our methodology introduces advanced automation to process complex case facts and derive semantic legal insights.

High Latency
Outcome Ambiguity

Literature & Innovation

Bridging the gap between global LLMs and local SL litigation. We utilize Semantic Argument Clustering (SAC) as a primary methodology for the region.
