PDF Buddy-RAG-Haystack

Description

PDF Buddy-RAG-Haystack is a Retrieval-Augmented Generation (RAG) application that allows users to upload PDF documents, process their content, and interact with them using a chatbot interface. Built using Haystack, Gradio, and Hugging Face API, this project enables users to retrieve relevant document content and generate AI-powered responses to queries.

Installation

To run this project locally, ensure you have Python installed and then install the required dependencies:

pip install gradio haystack-ai pypdf

Usage

Run the script to launch the Gradio web interface:

python app.py

Then, open the interface in your browser, upload a PDF, and start interacting with the chatbot.

Components

• Document Processing Pipeline: Converts, cleans, and embeds PDF text for retrieval.
• Query Pipeline: Retrieves relevant document snippets and generates AI-powered answers.
• Gradio Chatbot: Provides an easy-to-use web-based interface for user interaction.

How It Works

1. Upload a PDF: The document is processed and stored.
2. Ask a Question: The system retrieves relevant document content.
3. Generate an Answer: The AI model formulates a response based on the retrieved content.

Technologies Used

• Haystack for document processing and retrieval.
• Hugging Face API for response generation.
• Gradio for the user interface.
• SentenceTransformers for text embeddings.
