Welcome to Total Technology Zone - Tutorial 35
*Hi everyone! This is Ronnie, and welcome back to our channel, *Total Technology Zone*.* In today’s tutorial (*Tutorial 35*), we’ll explore **how to develop a RAG (Retrieval-Augmented Generation) system using IBM Docling and Llama Index**.
This tutorial is part of the Llama Index playlist, where I cover topics ranging from beginner to intermediate projects, tools, and integrations. Today, we’ll delve into how IBM Docling, an emerging open-source library for document parsing, can be used with Llama Index to create a robust RAG system.

Why IBM Docling?
IBM Docling is a recently developed library that offers advanced document parsing capabilities, especially for PDFs and similar formats. Its standout features include:
1. **Table and Figure Extraction**: Handles complex elements like tables, figures, and mathematical expressions.
2. **Versatility**: Works seamlessly with different document formats.
3. **Industry Relevance**: Addresses real-world challenges like structured document parsing and content extraction.
By integrating IBM Docling with Llama Index, we can build a powerful system to retrieve and generate insights from complex documents.

Tutorial Overview
In this tutorial, you’ll learn:
1. **Setting up the Environment**: Configuring the required libraries and components.
2. **Document Parsing**: Using IBM Docling to extract structured content from a PDF document.
3. **RAG Development**: Creating a query engine with Llama Index to interact with the parsed document.
4. **Query Execution**: Asking specific questions and retrieving well-structured answers.
---
Real-World Use Case
For this tutorial, we’ll use a publicly available PDF document from a repository (e.g., arXiv). The system will:
Parse the document using IBM Docling.
Transform the content into a structured format for indexing.
Enable users to query the document interactively, retrieving relevant and accurate responses.
---
Key Workflow
1. **Loading the Document**:
Use IBM Docling to load and parse a PDF document.
Convert the content into a structured format for further processing.
2. **Creating a Vector Index**:
Index the structured content using Llama Index to enable efficient querying.
3. **Building a Query Engine**:
Develop a query engine that integrates the parsed document with an LLM.
4. **Executing Queries**:
Test the system by asking questions related to the document’s content.
---
Benefits of This Approach
1. **Advanced Parsing Capabilities**:
Extracts complex elements like tables and figures, making it ideal for technical and academic documents.
2. **Enhanced Retrieval**:
Combines IBM Docling’s parsing power with Llama Index’s querying capabilities for superior results.
3. **Scalability**:
Applicable across industries, from research to enterprise knowledge management.
---
Example Scenarios
1. **Cybersecurity Whitepaper**:
Query: "What is the role of LLMs in cybersecurity as discussed in the document?"
Response: Retrieves relevant sections explaining how LLMs are used in security chatbots and query generation.
2. **Technical Documentation**:
Query: "What are the key features of LangChain mentioned in this document?"
Response: Highlights specific points related to LangChain and its integration.
3. **Dynamic Parsing**:
With tables or figures, Docling can extract structured data for further analysis.
---
Future Enhancements
1. **Complex Document Parsing**:
Include PDFs with images, charts, and multi-format content for advanced use cases.
2. **Integration with Other Libraries**:
Combine IBM Docling with tools like LangChain for broader workflows.
3. **Scalability**:
Expand the system to handle large-scale document repositories.
---
Recommendations for Practice
1. **Experiment with Different PDFs**:
Try parsing technical, academic, and business documents to understand the capabilities of IBM Docling.
2. **Explore Custom Queries**:
Frame specific questions to test the depth and accuracy of the RAG system.
3. **Combine with Other Tools**:
Integrate Docling with existing frameworks for comprehensive solutions.
