Instruction on Utilizing RAG for Semi-Structured Data Organization
In the ever-evolving world of artificial intelligence (AI), NVIDIA has made a significant stride with the development of an intelligent RAG pipeline designed to process semi-structured documents such as research papers, financial reports, or product manuals. This innovative system, specifically geared towards enhancing generative AI chatbots and cybersecurity workflows, has been making waves in the AI community.
At the heart of this system is an innovative method that combines intelligent unstructured data parsing with a multi-vector retriever. This combination results in a more robust and accurate system for handling documents containing both text and tables. The multi-vector retriever generates concise summaries of long text blocks and tables, ensuring that the language model receives the complete context in an easy-to-understand manner, leading to better, more reliable answers.
The retriever processes the summaries concurrently using a batch method. It consists of two storage components: ChromaDB for storing embedded summaries and a simple in-memory store for raw table and text content. The retriever creates a link between a summary in the vector store and its corresponding raw document in the docstore using unique IDs.
The brainchild behind this development is Harsh Mishra, an AI/ML Engineer who is passionate about GenAI, Natural Language Processing (NLP), and making machines smarter. The full code for the system can be accessed on the Colab notebook or the GitHub repository, allowing other developers to build upon this groundbreaking work.
The complete LangChain RAG pipeline is constructed to take a question, retrieve the relevant summaries, pull the corresponding raw documents, and pass everything to the language model to generate an answer. The summaries are created using a LangChain chain, ensuring a high degree of accuracy and reliability.
In a demonstration, the system was shown to correctly answer a question using the data from Table 1, proving its potential in real-world applications. With this development, NVIDIA continues to push the boundaries of what AI can achieve, paving the way for more intelligent and efficient document processing systems.
