Q1 multiple-choice · confidence-meaning What does an OCR confidence score of 0.87 actually mean?
Source: SPOCR02 §1.
Explanation: Confidence is engine-calibrated; not a literal probability. Same score from different engines has different meanings.
Q2 multiple-choice · per-field-thresholds Best practice for OCR thresholds across multiple fields?
Source: SPOCR02 §2.
Explanation: Per-field tuning matches threshold to stakes. Drug name + dosage = higher threshold than regulatory boilerplate.
Q3 multiple-choice · three-tier What’s the three-tier routing pattern for OCR output?
Source: SPOCR02 §3.
Explanation: Three-tier balances accuracy + throughput + cost. Low-confidence sends back to operator for better capture rather than wasting reviewer time.
Q4 scenario · throughput-calc 100,000 items/month, 15 % go to manual review at 2.5 min/item average.
Source: SPOCR02 §3.
Explanation: Standard production calculation — items × time/item ÷ hours/FTE.
Q5 multiple-choice · reviewer-ui What kills reviewer productivity?
Source: SPOCR02 §4.
Explanation: UI design directly impacts reviewer productivity at scale. Slow loading + missing context + no bulk ops = tax on every review.
Q6 true-false · drift OCR thresholds, once tuned, don’t need revalidation as long as the OCR engine remains the same.
Source: SPOCR02 §7.
Explanation: Drift happens via dictionary staleness, new product variants, lighting changes, capture conditions — not only engine updates. Quarterly revalidation recommended.
Q7 multiple-choice · metrics Which is NOT one of the 5 production metric categories?
Source: SPOCR02 §6.
Explanation: The 5 categories: accuracy, completeness, throughput, cost, quality. CSAT is a business metric, not a pipeline production metric.
Q8 scenario · drift-response Auto-accept rate has dropped from 80 % to 65 % over the last month. Where do you investigate first?
Source: SPOCR02 §7.
Explanation: Drift response = diagnose first. New products + engine update + capture drift are the 3 most common causes.
Q9 multiple-choice · reviewer-training Typical ramp time for new OCR reviewer to baseline productivity?
Source: SPOCR02 §5.
Explanation: Domain training + calibration + tool training takes time. Underestimating ramp leads to expecting too much of new reviewers.
Q10 multiple-choice · tuning-workflow What’s the FIRST step in threshold tuning workflow?
Source: SPOCR02 §8.
Explanation: Without ground truth, threshold tuning is guessing. The empirical foundation comes first.
