Stanford researchers have introduced RAPTOR, a tree-based retrieval system that enhances large language models with contextual information. RAPTOR utilizes a hierarchical tree structure to synthesize information from diverse sections of retrieval corpora, and it outperforms traditional methods in various question-answering tasks, demonstrating its potential for advancing language model capabilities.

Stanford Researchers Introduce RAPTOR: A Novel Tree-based Retrieval System
Retrieval-augmented language models often struggle with retrieving only short chunks of information, limiting their ability to understand overall document context and adapt to changes in the world. Existing methods also face challenges in integrating long-tail knowledge and representing large-scale discourse structure.
Addressing Limitations with RAPTOR
The innovative indexing and retrieval system, RAPTOR, developed by Stanford University researchers, aims to overcome these limitations. RAPTOR utilizes a tree structure to capture high-level and low-level details of text, enabling efficient and effective answering of questions at various levels. The key contribution is the use of text summarization for retrieval augmentation, enhancing context representation across different scales.
RAPTOR addresses reading semantic depth and connection issues by constructing a recursive tree structure that captures both broad thematic comprehension and granular details. It outperforms baseline methods across various question-answering datasets and showcases its effectiveness in handling thematic and multi-hop queries.
