Implementing an AI Chatbot for Enhanced Information Access with LLM and RAG

🤖 AI-Based Chatbot System with Retrieval-Augmented Generation (RAG)

🌐 Overview

In today’s digital era, quick and accurate information access is crucial, especially in education. To address this need, I developed an AI-based chatbot system for Catur Insan Cendekia University using the Retrieval-Augmented Generation (RAG) method. This system provides fast, relevant, and contextual information access for students and the public.

❓ What is Retrieval-Augmented Generation (RAG)?

RAG is an innovative approach that combines two main components:

  1. 🗂️ Indexing and Retrieval
  2. 📝 Generation

This method enables the system to:

  • 🔍 Search and retrieve relevant information from a database.
  • 💬 Process and generate contextual, informative responses.

⚙️ How It Works

1. Indexing

  • 📄 Documents are structured hierarchically into “parent chunks” and “child chunks”.
  • 🧠 Each chunk is transformed into vectors using embedding models like Sentence-BERT to improve semantic accuracy.

2. Retrieval

  • 🔎 Utilizes a Parent Document Retriever to locate the most relevant data based on user queries.
  • 🎯 Pinpoints the exact child chunk while providing the parent chunk as context for a comprehensive response.

3. Augmented Information

  • ✨ The retrieved data is enhanced with:
    • 🗣️ Language model instructions.
    • 🗃️ Vector database context.
    • 💡 User query inputs.

4. Generation

  • 🚀 The enhanced information is processed using a large language model (LLM) such as Gemini AI to generate coherent and informative responses.

🛠️ Tools Used

To build this RAG-based chatbot, the following tools and technologies were utilized:

  • 🧰 LangChain: Framework for building applications powered by LLMs.
  • 🤗 HuggingFace: Pre-trained NLP models for embedding and text processing.
  • 🗄️ ChromaDB: Vector database for storing embeddings.
  • 🌌 Gemini AI: Large language model for generating responses.
  • 📦 Unstructured IO: Document processing and structuring.
  • 🌐 Django: Backend framework for building the API.
  • ⚡ Redis: Fast data storage for caching.
  • 🐝 Celery: Task queue for asynchronous processing.
  • 🔧 Other Python libraries to support the implementation.

✨ Features

  • ⚡ Fast and Relevant Responses: Provides accurate and contextual answers to user queries.
  • 📚 Information Hierarchy: Structures documents to ensure efficient retrieval.
  • 🎓 Educational Focus: Tailored to meet the needs of students and the academic community.
