Legal Summarizer

Pandas Python Streamlit

Summarizing legal documents made easy using Retrieval-Augmented Generation (RAG) and Large Language Models (LLMs).


πŸ“Œ Overview

Legal documents are often dense, complex, and difficult for non-lawyers to understand. This project leverages Information Retrieval and Context Augmentation using Large Language Models (LLMs) to simplify and summarize contracts, agreements, and other legal texts.

🚨 The Problem: Understanding Legal Documents is Hard

  • Legal documents use complex terminologies that require domain expertise.
  • They contain long, dense sentences that make key information difficult to extract.
  • They rely on statutes, legal citations, and references, assuming prior knowledge.
  • The conservative and risk-averse language results in intricate phrasing.
  • Misinterpretation can lead to serious consequences, discouraging individuals from handling contracts themselves.

πŸ€– The Solution: AI-Powered Legal Summarization

With the advancements in Large Language Models (LLMs), we can now:
βœ… Extract key insights from legal documents
βœ… Summarize complex clauses into easy-to-read formats
βœ… Retrieve relevant information using RAG (Retrieval-Augmented Generation)
βœ… Improve accessibility of legal content for non-lawyers


πŸ“Œ How Does It Work?

πŸ” Retrieval-Augmented Generation (RAG)

RAG enhances the summarization process by first searching for relevant content and then reconstructing it using an LLM.

Step 1: Document Processing

  • Processing complex agreements, contracts and other legal documents, extracting information using OCR, transformers, etc and chunking, and tagging them with relevant topics for efficient keyword search.

Step 2: Document Retrieval

  • Uses BM25 ranking (keyword-based) or Semantic Search (context-based) to fetch relevant parts of legal documents.

Step 3: Context Augmentation

  • The retrieved text is then passed to an LLM to generate a structured and readable summary.
