Creating a sophisticated risk assessment system for legal case analysis using machine learning and AWS serverless architecture
The Challenge
Our client, a forward-thinking legal consultancy, approached us to develop an innovative document analysis platform that would transform traditional legal research into a data-driven intelligence process. They needed a solution that would:
- Extract valuable insights from historical case data
- Process and analyze lengthy legal documents (up to 500 pages)
- Leverage advanced AI to extract meaningful insights from complex legal text
- Deliver consistent evaluations across multiple jurisdictions
- Scale effectively to handle an increasing volume of case analysis
- Provide clear, actionable insights for legal professionals and their clients
- Allow for continuous refinement based on new data and outcomes
Our Solution
We designed and implemented a cutting-edge legal document analysis platform using serverless architecture and AI technologies. Our approach included:
Architecture
- AWS CDK infrastructure-as-code for consistent and reproducible deployments
- Serverless processing pipeline using AWS Step Functions and Lambda functions
- Document storage and versioning with S3, featuring proper encryption and lifecycle policies
- DynamoDB for storing jurisdiction-specific data
- Integration with advanced AI models via Amazon Bedrock
- API Gateway for secure access to the analytics platform
- Comprehensive notification system using SNS and SQS for error handling
Development Process
- Proof of Concept (POC) phase focused on a single jurisdiction to validate the approach
- Iterative delivery methodology for continuous improvement
- Data-driven model refinement allowing the system to learn from new cases
- Comprehensive security measures throughout the application
- Automated CI/CD pipeline for reliable deployments
- Thorough documentation
