POC1: Core Workflow with Quality Gates

 Phase Goal: Prove AKEL can produce credible, quality outputs without manual intervention Success Metric: <10% hallucination rate, quality gates prevent low-confidence publications == 1. Overview == POC1 validates that the core AKEL workflow (Article → Claims → Verdicts) can produce trustworthy fact-checking analyses automatically. This phase implements 2 critical quality gates to prevent low-quality outputs from being published. Key Innovation: Quality validation BEFORE publication, not after What We're Proving:

  • AKEL can reliably extract factual claims from articles
  • AKEL can generate credible verdicts with proper evidence
  • Quality gates prevent hallucinations and low-confidence outputs
  • Fully automated approach is viable == 2. Scope == === In Scope === * Core AKEL workflow (claim extraction, verdict generation)
  • Gate 1: Claim Validation (factual vs. opinion/prediction)
  • Gate 4: Verdict Confidence Assessment (minimum 2 sources, quality thresholds)
  • Basic UI to display results
  • Manual quality tracking === Out of Scope (Deferred to POC2+) === * User accounts / authentication
  • Corrections system
  • Search engine optimization (ClaimReview schema)
  • Image verification
  • API endpoints
  • Archive.org integration
  • Security hardening
  • A/B testing
  • Gates 2 & 3 (Evidence relevance, Scenario coherence) == 3. Requirements == === 3.1 NFR11: Quality Assurance Framework (POC1 Lite Version) === Priority: CRITICAL - Core POC1 Requirement Fulfills: AI safety, credibility, prevents embarrassing failures Specification: AKEL must validate outputs before displaying to users. POC1 implements a 2-gate subset of the full NFR11 framework. ==== Gate 1: Claim Validation ==== Purpose: Ensure extracted claims are factual assertions, not opinions or predictions Validation Checks:
  1. Factual Statement Test: Can this be verified with evidence?
    2. Opinion Detection: Contains hedging language? ("I think", "probably", "best", "worst")
    3. Specificity Score: Contains concrete details? (names, numbers, dates, locations)
    4. Future Prediction Test: Makes claims about future events? Pass Criteria:
    - isFactual: true
    - opinionScore: 0.3
    - specificityScore: 0.3
    - claimType: FACTUAL
    Action if Failed:
  • Flag as "Non-verifiable: Opinion/Prediction/Ambiguous"
  • Do NOT generate scenarios or verdicts
  • Display explanation to user Target: 0% opinion statements processed as facts ==== Gate 4: Verdict Confidence Assessment ==== Purpose: Only publish verdicts with sufficient evidence and confidence Validation Checks:
  1. Evidence Count: Minimum 2 independent sources
    2. Source Quality: Average reliability ≥ 0.6 (on 0-1 scale)
    3. Evidence Agreement: % supporting vs. contradicting ≥ 0.6
    4. Uncertainty Factors: Count of hedging statements in reasoning Confidence Tiers:
    HIGH (80-100%): -3 sources -0.7 average quality -80% agreement MEDIUM (50-79%): -2 sources -0.6 average quality -60% agreement LOW (0-49%): -2 sources BUT low quality/agreement INSUFFICIENT: - <2 sourcesDO NOT PUBLISH POC1 Publication Rule:
  • Minimum MEDIUM confidence required
  • Blocked verdicts show "Insufficient Evidence" message Target: 0% verdicts published with <2 sources === 3.2 Modified FR7: Automated Verdicts (Enhanced) === Enhancement for POC1: After AKEL generates a verdict, it must pass through the quality validation pipeline: AKEL Workflow (POC1): 1. Extract claims from article
    2. [GATE 1] Validate each claim is fact-checkable(pass claims only)
    3. Generate verdicts for each claim
    4. [GATE 4] Validate verdict has sufficient evidence(pass verdicts only)
    5. Display to user Failed claims/verdicts:
    - Store in database with failure reason
    - Display explanatory message to user
    - Log for quality metrics tracking
    Updated Verdict States:
  • PUBLISHED - Passed all gates
  • INSUFFICIENT_EVIDENCE - Failed Gate 4
  • NON_FACTUAL_CLAIM - Failed Gate 1
  • PROCESSING - In progress
  • ERROR - System failure === 3.3 Modified FR4: Analysis Summary (Enhanced) === Enhancement for POC1: Analysis Summary must now display quality metadata: Analysis Summary: Total Claims Found: 5 Verifiable Claims: 3 Non-verifiable (Opinion): 1 Non-verifiable (Prediction): 1 Verdicts Generated: 3 High Confidence: 1 Medium Confidence: 2 Insufficient Evidence: 0 Evidence Sources: 12 total Average Source Quality: 0.73 Quality Score: 8.5/10 == 4. Success Criteria == POC1 is considered SUCCESSFUL if: ✅ Functional:
  • Processes diverse test articles without crashes
  • Generates verdicts for all factual claims
  • Blocks all non-factual claims (0% pass through)
  • Blocks all insufficient-evidence verdicts (0% with <2 sources) ✅ Quality:
  • Hallucination rate <10% (manual verification)
  • 0 verdicts with <2 sources published
  • 0 opinion statements published as facts
  • Average quality score ≥7.0/10 ✅ Performance:
  • Processing time reasonable for POC demonstration
  • Quality gates execute efficiently
  • UI displays results clearly ✅ Learnings:
  • Identified prompt engineering improvements
  • Documented AKEL strengths/weaknesses
  • Validated threshold values
  • Clear path to POC2 defined == 5. Decision Gates == POC1 → POC2 Decision: * IF hallucination rate >10% → Pause, improve prompts before POC2
  • IF majority of claims non-processable → Rethink claim extraction approach
  • IF quality gates too strict (excessive blocking) → Adjust thresholds
  • IF quality gates too loose (hallucinations pass) → Tighten criteria Only proceed to POC2 if all success criteria met == 6. Architecture Notes == POC1 Simplified Architecture: User Input AKEL Processing Quality Gates Display (claim extraction (Gates 1 & 4) + verdicts) vs. Full System (Future): Input Claim Extractor Scenario Generator Evidence Linker Verdict Generator All 4 Gates Review Queue Publication POC1 Acceptable Simplifications:
  • Single AKEL call (not multi-component pipeline)
  • No scenarios (implicit in verdicts)
  • Basic evidence linking
  • 2 gates instead of 4
  • No review queue See: Architecture for details == Related Pages == * Roadmap Overview - All phases
  • POC2 Requirements - Next phase
  • Requirements - Full system requirements
  • Architecture - System architecture
  • NFR11 Full Specification - Complete quality framework Document Status: ✅ POC1 Specification Complete - Ready for Implementation Version: V0.9.70
