Research on Knowledge Modeling & Semantic Systems

By G. Sawatzky

Exploring enterprise architecture, formal modeling methods (DEMODEMO (Design & Engineering Methodology for Organisations) is a research-based approach that models the essential structure of business operations—what actually happens, separate from how it's implemented., ORMORM (Object-Role Modeling) is a conceptual modeling method, focusing on facts and business rules rather than implementation details.), and semantic foundations for intelligent systems

About

I work at the intersection of formal modeling, semantic systems, and practical application. My background includes over a decade in Banking as a Service and Ad Tech, where I've applied enterprise architecture and integration methodologies to complex business problems.

This site documents my research and explorations in conceptual modeling (DEMODEMO (Design & Engineering Methodology for Organisations) is a research-based approach that models the essential structure of business operations—what actually happens, separate from how it's implemented., ORMORM (Object-Role Modeling) is a conceptual modeling method, focusing on facts and business rules rather than implementation details.), knowledge representation, and the integration of symbolic and learning-based approaches to AI. I build tools and demonstrations to explore how formal methods can create more explainable, maintainable intelligent systems.

Tools & Demonstrations

Credit Card Approval System Demo

This demonstration application was built using the ORM Toolkit with AI code assistance. It shows how formal conceptual models drive intelligent decision systems with explainable logic and semantic validation—the same approach I apply to API integration projects.

What It Demonstrates:

  • Semantic business rules (not hardcoded logic)
  • Explainable decision-making
  • AI-assisted development with formal foundations
  • Practical application of ORM methodology
