A powerful LLM-powered pipeline for summarizing legal documents, generating intelligent counterarguments, and enabling context-aware legal question answering. This system is designed to support individuals in understanding legal documents and crafting robust responses to legal accusations.
📌 Table of Contents
This project aims to empower users to generate intelligent legal counterarguments and ask detailed questions about legal documents using large language models (LLMs) like OpenAI’s gpt-3.5-turbo. It supports legal professionals, individuals without legal expertise, and researchers who need automated assistance with legal content.
- ✔️ Automatic summarization of lengthy legal documents
- ✔️ Counter-argument generation using LLMs
- ✔️ Multi-format document ingestion (PDF, HTML, TXT)
- ✔️ Semantic search & question-answering with Pinecone vector store
- ✔️ LangChain-powered modular pipelines for flexibility and scalability
-
Input Parsing: Load large legal documents from various formats.
-
Chunking: Split into overlapping chunks (~2000 tokens) for contextual coherence.
-
Prompt Design: Use custom prompt templates tailored for legal summarization.
-
LLM Summarization: Generate summary chunks using load_summarize_chain from LangChain.
-
Summary Fusion: Combine individual summaries into a final, cohesive summary.
-
Counter-Argument Generation: Use OpenAI’s GPT models to derive intelligent counterarguments from the final summary.
-
Multi-format Support: Ingest files in PDF, text, or HTML format.
-
Recursive Chunking: Segment using RecursiveCharacterTextSplitter (~1000 tokens with overlap).
-
Embedding: Create dense vector embeddings using OpenAI's text-embedding-ada-002.
-
Vector Store Setup: Store vectors in Pinecone for semantic search.
-
QA Chain: Use LangChain’s load_qa_chain to retrieve relevant content and generate answers from LLM.
