Why it matters
Existing document parsing benchmarks focus on page-level tasks, leaving document-level structure recovery unevaluated. LongDocBench provides a standardized evaluation for tasks that are critical for understanding long documents, enabling comparison of parsers on hierarchy and relationship recovery.
Motivation
Parsing visual documents into machine-readable representations is fundamental to document intelligence.
