Definition
An advanced text-segmentation strategy that utilizes embedding similarity or LLM-driven analysis to divide documents at natural thematic boundaries rather than arbitrary token limits. This ensures that individual chunks maintain logical cohesion and contextual integrity, which significantly improves retrieval precision and reduces noise in RAG systems.
Splitting by meaning and topic shifts rather than fixed character counts or structural markers like double newlines.
"A surgical scalpel cutting along anatomical muscle groups rather than a uniform cookie cutter stamping out identical circles."
- Embedding(Prerequisite)
- Cosine Similarity(Underlying Mechanism)
- Recursive Character Text Splitting(Alternative Approach)
- Retrieval Augmented Generation (RAG)(Core Application)
