The article explains semantic text chunking, a technique for automatically grouping similar pieces of text to be used in pre-processing stages for Retrieval Augmented Generation (RAG) or similar applications. It uses visualizations to understand the chunking process and explores extensions involving clustering and LLM-powered labeling.
This article discusses the importance of chunking, embedding, and indexing in RAGs (Recursive Auto-Segmented Graphs). The author compares recursive character splitting and semantic splitting techniques for text chunking and suggests the use of agentic chunking for superior RAG retrieval.
