Doctopus: Budget-aware Structural Table Extraction from Unstructured Documents
Summary: Doctopus extracts structural attributes from unstructured documents under user-specified LLM budgets. It combines index-based chunk pruning, per-attribute quality estimation, and dynamic strategy selection across LLM/non-LLM methods, improving quality 11% at equal cost.
