New DOSA framework enhances long document structure analysis

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework called DOSA (DOcument Structure Analyzer) to improve the analysis of long and visually rich documents. This framework uses a tree-guided, self-regressive approach to infer hierarchical and ordering relationships between page objects like tables and headers. By fusing visual, textual, and layout features, DOSA incrementally builds a semantic tree that provides structural context for subsequent analysis, leading to significant improvements on benchmarks like DocHieNet.

IMPACT This framework could improve information retrieval and understanding in complex, multi-page documents.

    DOSA: A Tree-Guided, Self-Regressive Framework for Long Document Structure Analysis

    arXiv:2607.22679v1 Announce Type: new Abstract: In visually-rich documents, information is encoded not only in individual page objects such as tables, headers, and text blocks, but also in the structural relations among them, making document structure analysis fundamental to info…
