Data Verification Status Taxonomy
To maintain rigorous scientific standards, Sci-database differentiates between automated signals and human audit:
Extracted
Value located and extracted from the full-text PDF by the Kateeb engine.
Model-Agreed
An independent second model produced a compatible value during automated second-pass review.
Human-Reviewed
A named researcher audited the value against the visual page coordinates.
Benchmark-Validated
Performance evaluated against a standardized, published evaluation protocol.
Replicated
An independent external research group reproduced the extraction and experimental result.
