1.Quantifying Extraction Defects Across Multilingual Data
Data Research Dashboard · 2026
This dashboard illustrates an adjacent workflow for tracking error rates, a method highly transferable to identifying defects in manufacturing. A data researcher quantified severe OCR and PDF extraction degradation across six languages. A stacked bar chart shows Russian with the highest defect rate at 105.9 failures per 10,000 characters, followed by Arabic (54.4) and Chinese (41.1), all exceeding the English baseline of 18.4. A heatmap visualizes failure-rate multiples, revealing Chinese OCR artifacts occur at 24.3x the English rate. By categorizing errors like noise events and mid-word breaks, the researcher provided concrete metrics to justify targeted remediation for these specific data failures.
What it shows:
Categorizing and visualizing failure rates against a baseline clearly identifies which specific processes or categories require immediate remediation.
