Tessera系统通过保留结构化证据来增强网络RAG

研究人员推出Tessera,一个旨在通过将检索过程与读取器上下文分离来改进网络检索增强生成(RAG)的新颖系统。与将页面分割成固定大小块的传统RAG方法不同,Tessera将HTML重构为细粒度的证据单元,保留了表格和信息框等结构化内容。这种方法在各种问答基准和RAG管道配置中,将答案准确性提高了5到6个百分点,而没有增加令牌预算。 AI

影响 Tessera的方法通过更好地保留结构化数据,可以显著提高RAG系统的准确性和可靠性,从而可能带来更强大的AI应用。

    Tessera:用于网络检索增强生成的结构化证据单元

    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…
