Contract Q&A RAG System

Overview

This project aims to develop a high-precision legal expert system for contract Q&A using Retrieval-Augmented Generation (RAG). The system leverages advanced natural language processing (NLP) techniques to provide accurate and context-aware answers to questions about legal contracts and integrates a powerful language model with a custom retrieval mechanism to provide accurate and contextually relevant answers to contract-related queries.

Installation

1. Clone the repository

git clone https://github.com/dev-abuke/Legal_Expert_Contract_Advisor_Using_Precision_RAG.git

2. Navigate to project directory

cd Legal_Expert_Contract_Advisor_Using_Precision_RAG

3. Create a virtual environment

python -m venv venv

4. Activate the environment

source venv/bin/activate  # On Windows, use venv\Scripts\activate

3. Install the required dependencies:

pip install -r requirements.txt

Usage

1. Prepare your contract data and place it in the data/raw/ directory.

2. Preprocess the data

python src/data/preprocess.py

3. Run the RAG system

python main.py

4. Evaluate the system performance:

python src/evaluation/evaluate.py

Development

• Use the Jupyter notebooks in the notebooks/ directory for exploration and prototyping.
• Implement core functionality in the src/ directory.
• Add unit tests in the tests/ directory.
• Use config.yaml to manage project settings.

Evaluation

The system's performance is evaluated using the following metrics

• Retrieval precision and recall
• Answer relevance
• Factual accuracy
• Response coherence

Refer to the evaluation notebook for detailed results and analysis.

Optimization Techniques

This project explores various optimization techniques, including

1. Advanced embedding models for retrieval
2. Hybrid search methods
3. Query expansion
4. Chunking strategies
5. Prompt engineering

Contributing
