In today’s world of information overload, documents come in all forms — PDFs, Word files, PowerPoint presentations — containing a complex mix of text, tables, images, and infographics. Accurately transcribing and extracting relevant information from these files, especially for tasks like retrieval-augmented generation (RAG) models, can be a daunting task. One key challenge lies in how we chunk the data. Many chunking strategies like recursive chunking, semantic chunking, agentic chunking, and page-wise chunking fail to capture the document’s hierarchical structure, leading to incomplete context and hallucinated answers from models like GPT.

A promising solution to these challenges is the advanced hierarchy-based chunking strategy, which works seamlessly across all types of files, including PDFs, PowerPoint presentations, Word documents, and more. This latest chunking method is designed to retain the structural nuances of various document formats, ensuring that the context remains intact during the extraction process. By addressing the limitations of traditional chunking techniques, this innovative approach enhances the accuracy and relevance of the information retrieved, ultimately improving the performance of RAG models and providing a more reliable foundation for data-driven insights

When breaking a document into smaller parts, most… Read the full blog for free on Medium.
