Norwegian Census Archival Transformation

80+ million Norwegian historical records processed at 99.5% accuracy across five centuries of ancestry data. A leading genealogy platform required a scalable archival transcription model to unlock centuries of Norwegian birth, marriage, census and military records for global family-history research. The project involved highly complex non-English handwritten archives dating back to the 15th century — records that conventional OCR systems and manual workflows could not process accurately at scale.

"Large-scale Norwegian archive transcription preserved centuries of ancestry records, enabled global genealogy research and delivered highly accurate searchable historical datasets. "

Challenge

The archive contained archaic Norwegian handwriting styles, faded manuscript imagery and centuries-old linguistic variations that standard transcription systems could not interpret reliably. Manual processing lacked scalability and introduced risks around data consistency, auditability and transcription integrity across millions of historical records. Many source images also contained damaged or partially illegible text requiring specialist interpretation workflows.

Approach

SBL Infotech deployed DAMS — its Digital Archives Management System — to govern the complete genealogical transcription workflow from image intake through linguistic interpretation, validation and structured data delivery. Norwegian genealogists and linguistic experts worked alongside specially trained transcription teams skilled in archaic Scandinavian handwriting styles. Multi-stage transcription workflows processed census, death, marriage and military records into searchable digital datasets while proprietary discrepancy-detection systems identified hidden inconsistencies and transcription anomalies missed by conventional methods. Structured quality validation frameworks ensured accuracy reached 99.5% across all delivered records.

Outcome

The client transformed inaccessible historical archives into a globally searchable ancestry intelligence platform capable of supporting millions of genealogical searches and family-history discoveries worldwide. Records once locked inside unreadable handwritten manuscripts became structured, searchable datasets accessible to researchers and descendants across borders. The engagement established a repeatable multi-language archival transcription model capable of scaling across centuries-old historical collections — preserving cultural heritage while accelerating global genealogy research with enterprise-grade accuracy and transparency.

Reliving History with Geospatial Intelligence
US university research initiative

Reliving History with Geospatial Intelligence

260 years of fragmented historical maps transformed into a georeferenced spatial database for anthropological and land-use analysis. A prominent US university needed to study the historical evolution of Uxeau, France, across multiple centuries of land ownership, taxation, and agricultural activity. The research depended on digitising and harmonising vintage maps dating back to 1759 — each with different scales, formats, and levels of degradation — into a single spatially accurate GIS environment suitable for comparative analysis. 260+ years of historical mapping digitised and layered. Lambert II precision georeferencing using Esri GIS tools. Multi-era land parcel and feature extraction delivered at scale.

AI-Powered CT Scan Annotation

30,000+ CT scans annotated at 98.9% segmentation accuracy for AI-driven radiology models. A US-based MedTech AI company developing radiology models for tumour detection and analysis required clinically precise annotation support to accelerate model training and validation. Existing workflows faced rising costs, limited access to qualified medical annotators and growing compliance pressure around handling sensitive patient imaging data.

HIPAA-compliant medical annotation workflows improved radiology AI accuracy, accelerated tumour detection model training and reduced operational costs significantly.

Mortgage Foreclosure Data Management

40%+ faster foreclosure data processing with 50% higher accuracy across multi-county property records. A US-based mortgage data company managing property intelligence across more than 155 million properties and 3,000+ counties required a scalable operational model for foreclosure data collection and processing. Their existing workflows relied heavily on manual back-office operations, creating delays, inconsistencies and rising operational overhead across fragmented government data sources.

Standardised foreclosure processing improved nationwide property data accuracy, reduced turnaround times and created a scalable mortgage intelligence operations framework.
