White Paper: AI Résumé Parsing & Scoring

Universal intake

We ingest résumés from everywhere—job portals, email, ATS exports, and cloud drives—across PDF, DOCX, images, and text. Encodings are normalized, language and structure detected, and malformed files corrected. Each document is hashed for lineage, time-stamped, and processed with PII minimization. The output is a consistent, validated candidate profile ready for enrichment, scoring, and audit—so no viable applicant is lost to format friction or pipeline fragmentation.

De-duplication

We combine content hashing, semantic similarity, and entity-level graphs to find and collapse near-duplicates across formats and time. Name variants, normalized emails/phones, employment overlaps, and skills vectors are weighted to avoid false merges. Decisions are explainable, reversible, and fully logged—preserving provenance while delivering a clean golden record per candidate. Recruiters gain clarity and speed without sacrificing trust or historical context.

Context-aware scoring

Hybrid retrieval—keywords, ontologies, and embeddings—maps role requirements to candidate evidence. We evaluate depth, recency, and relevance of skills; project impact; domain signals; and constraints such as location or clearance. Inflated claims and buzzword stuffing are down-weighted. Every score ships with reasons, confidence, and suggested next steps—so teams act quickly with defensible shortlists and clear follow-ups tailored to each requisition’s realities.

Role Compatibility Score

Beyond skills matching, this composite measures adjacency, growth trajectory, and transferability. It weights capability clusters, tool ecosystems, industry patterns, and soft-signal indicators drawn from achievements and tenure dynamics. Calibrated on outcomes, the score reveals fit gaps and coachable areas. Recruiters can adjust business-specific weights and see why a candidate surfaced—what mattered, by how much, and which evidence supported the ranking.

Human-in-the-loop

Recruiters remain decision-makers. They can reweight criteria, approve or dismiss recommendations, annotate edge cases, and trigger deeper checks. Every intervention is captured in an audit trail and feeds learning loops that refine future rankings while preserving governance. Guardrails prevent policy bypasses, and structured review queues accelerate throughput without compromising fairness, accountability, or the nuanced context only humans can bring to hiring.

30/90/180 learning

Post-hire outcomes close the loop. We ingest probation results, manager feedback, ramp velocity, and early retention to recalibrate features and weights. Reliable predictors are strengthened and misleading proxies suppressed. Drift monitors watch role demands and market shifts. Recommendations stay aligned with real performance, improving shortlist precision over time and anchoring AI behavior in measurable business results rather than static assumptions.

Data Fusion

Data Fusion transforms messy inputs into structured, trustworthy data. We parse sections, fix date ranges, align titles to standardized taxonomies, deduce seniority, and map skills to canonical entities with versions. Employer names are reconciled, industries inferred, and fragmented histories stitched. Ambiguities are flagged with confidence and suggested corrections. Result: clean, schema-conformant profiles that make scoring fairer, explainability clearer, and analytics consistently comparable across sources and time.

• APIs for lists, details, explainers, and exports
• Event hooks for feedback at 30/90/180 days

Feature engineering

We derive robust features from text, layout, timelines, employer graphs, certifications, and tool ecosystems. Temporal decay handles recency, streak features capture sustained practice, diversity vectors reflect breadth, and adjacency encodes learnability. Each feature is documented with purpose, ranges, and lineage. Engineers can simulate weight changes while auditors inspect exactly which inputs influenced any recommendation and whether protected attributes were strictly excluded from consideration by policy-as-code.

Model ensemble & calibration

A blended ensemble—BM25 retrievers, transformers, and gradient models—reduces single-model bias and improves stability. Platt scaling and isotonic regression calibrate scores to probabilities aligned with historical outcomes. Per-role calibration sets expected distributions so “top 5%” is consistent. Confidence intervals travel with each score. Versioned artifacts, training sets, and hyperparameters enable rollbacks, A/B tests, and regulated model lifecycle management across hiring domains.

Role Compatibility breakdown

The composite explains itself: capability fit, domain fit, toolchain overlap, trajectory, and constraints appear as separate bars with weights and evidence snippets. Clicking any bar reveals the sentences, entities, and timelines that moved the needle. Recruiters tweak weights for a requisition, preview impact, and save templates. This turns “why this candidate?” into an auditable narrative tied directly to business context and evidence.

Risk & fairness checks

Pre-deployment and continuous tests scan for disparate impact, selection-rate anomalies, proxy features, and geography-driven leakage. Monitors watch subgroup calibration and error asymmetry. When thresholds trigger, the system explains which features contributed and proposes mitigations—feature suppression, reweighting, or alternative retrieval. All fairness interventions are recorded with justifications, keeping recommendations equitable, defensible, and aligned to company policy and jurisdictional regulations.

Human oversight & controls

Explainability is actionable: reviewers request more evidence, add counter-evidence, or mark recommendations as misleading. Controls include approval gates, dual review for sensitive roles, and red-flag prompts when evidence is thin. Every click is captured in an audit trail. Oversight signals retrain prioritization—features that repeatedly mislead are down-weighted—preserving speed while ensuring accountability remains with experienced humans, not automated pipelines.

Outcome-linked learning

Scores earn trust when they predict reality. We feed 30/90/180-day metrics—first-round pass rates, ramp curves, manager ratings, and early attrition—into retraining schedules. We compare cohorts by decision path to detect harmful shortcuts or overlooked talent. The system proposes targeted recalibration and shows expected ROI from adjustments. Leaders see a living model that learns responsibly from outcomes, not static rules.

Auditability & lineage

Every recommendation is reproducible. We store source files, parsed structures, feature values, retrieval hits, model versions, and random seeds. A single audit link reconstructs the decision exactly. Policy-as-code snapshots prove that banned attributes never entered the graph. Exports support regulator or client reviews without exposing proprietary IP. Disciplined lineage makes governance practical and accelerates security and vendor assessments.

Data Fusion (scoring context)

Data Fusion underpins fair scoring. We standardize titles, unify skill spellings, resolve employer identities, align dates, and fill inferred gaps with explicit confidence. Ambiguities surface to reviewers with suggested fixes. Clean, canonical features stabilize model behavior, reduce false mismatches, and improve comparability across roles. Data Fusion artifacts are versioned so investigators can trace how a corrected entity or timeframe changed a candidate’s score and rationale downstream.

Organizations typically track acceleration and quality improvements after deploying résumé parsing & scoring. Focus on cycle time, recruiter capacity, early performance, retention, and process consistency.

• Time-to-shortlist / time-to-hire
• First-round quality and pass-ups
• Recruiter hours shifted to high-value work
• Early tenure performance and retention
• Compliance & trust indicators

Exact percentages vary by role family, market, and baseline; establish pilot baselines and iterate.
