RAPTOR

RAPTOR is a retrieval method that clusters and recursively summarizes document chunks into a tree of summaries, letting a system retrieve at different levels of detail, from specific passages to high-level overviews.

RAPTOR sits in the Retrieval & memory part of the Agentik {OS} glossary, which defines the words used to build and run AI agent systems.

Also called recursive abstractive processing for tree-organized retrieval.
