Tessera system enhances web RAG by preserving structured evidence

Researchers have introduced Tessera, a novel system designed to improve web retrieval-augmented generation (RAG) by decoupling the retrieval process from the reader's context. Unlike traditional RAG methods that split pages into fixed-size chunks, Tessera reconstructs HTML into fine-grained evidence units, preserving structured content like tables and infoboxes. This approach enhances answer accuracy by 5 to 6 points across various question-answering benchmarks and RAG pipeline configurations, without increasing token budgets. AI

IMPACT Tessera's approach could significantly improve the accuracy and reliability of RAG systems by better preserving structured data, potentially leading to more robust AI applications.

    Tessera: Structure-Completed Evidence Units for Web Retrieval-Augmented Generation

    Web retrieval-augmented generation (RAG) splits a page into fixed-size text chunks or, in recent visual pipelines, screenshot tiles, and the retrieved item serves at once as the unit of indexing, ranking, and reading. We trace answer evidence from source HTML to reader input over…
