SPOCR01
Q1 multiple-choice · generic-vs-specialized What’s the primary accuracy lever for production OCR beyond generic engine accuracy?
Source: SPOCR01 §1.
Explanation: Tuning beats vendor change for closing the 70-90% → 95+% accuracy gap. Domain specialization is the highest-leverage intervention.
Q2 multiple-choice · 5-patterns Which is NOT one of the 5 domain patterns covered in SPOCR01?
Source: SPOCR01 §2-§6.
Explanation: The 5 patterns are retail planogram, pharmaceutical labeling, GS1-coded, industrial labeling, multi-language. Social media reviews aren’t a pattern here.
Q3 scenario · pharma A pharma customer wants OCR on drug labels with batch numbers + expiration dates. Right discipline?
Source: SPOCR01 §3.
Explanation: Pharma stakes mean false-positive costs > false-negative costs. Discipline: high threshold + manual review + dictionary matching.
Q4 scenario · gs1 A GS1-coded products customer wants OCR + barcode integration. What’s the key triangulation discipline?
Source: SPOCR01 §4.
Explanation: Triangulation: barcode value + on-label text must agree. Mismatches indicate label misprint, OCR error, or master data drift — all worth catching.
Q5 multiple-choice · multi-language What’s the key first step in multi-language OCR?
Source: SPOCR01 §6.
Explanation: Language detection first, then OCR with language-appropriate model = better per-language accuracy + smaller processing footprint.
Q6 true-false · cheat-sheet A domain cheat sheet is a one-time setup document; once built it doesn’t need updating.
Source: SPOCR01 §8.
Explanation: Cheat sheet is a living document. Updated as customer engagement evolves; passed to anyone joining the project.
Q7 multiple-choice · decision-tree First question in the OCR project decision tree (§7)?
Source: SPOCR01 §7.
Explanation: Regulatory stakes drive the threshold + review discipline. Low-stakes engagements + high-stakes engagements diverge sharply in pipeline design.
Q8 scenario · dictionary A customer claims “we don’t have master data for our products” but wants 95 %+ OCR accuracy.
Source: SPOCR01 §1 + §8.
Explanation: “We don’t have master data” is rarely literally true. Most organizations have some form of product catalog somewhere; surfacing it unlocks the dictionary approach.
Q9 multiple-choice · industrial-labeling A consumer electronics OEM ships to EU + US + JP. Each variant has region-specific regulatory labels. What’s the OCR Specialist’s discipline?
Source: SPOCR01 §5.
Explanation: Industrial labeling has region-specific labels + regulatory symbols + lifecycle degradation. Pipeline accommodates all three.
Q10 multiple-choice · escalation Which situation warrants escalation to PhotoRobot Engineering beyond standard OCR Specialist scope?
Source: SPOCR01 §9.
Explanation: Standard scope handles tuning, language expansion, volume scaling. Out-of-scope: fundamental engine limitations or custom model training.
