Jacobus Geluk



The arrival of AI agents creates urgency around the need to guide and govern them.



Drawing on his 15-year history in building reliable AI solutions for banks and other enterprises, Jacobus Geluk sees a standards-based data-product marketplace as the key to creating the thriving data economy that will enable AI agents to succeed at scale.



Jacobus launched the effort to create the DPROD data-product description specification, creating the supply side of the data market. He's now forming a working group to document the demand side, a "use-case tree" specification to articulate the business needs that data products address.



We talked about:



his work as CEO at Agnos.ai, an enterprise knowledge graph and AI consultancy

the working group he founded in 2023 which resulted in the DPROD specification to describe data products

an overview of the data-product marketplace and the data economy

the need to account for the demand side of the data marketplace

the intent of his current work on to address the disconnect between tech activities and business use cases

how the capabilities of LLMs and knowledge graphs complement each other

the origins of his "use-case tree" model in a huge banking enterprise knowledge graph he built ten years ago

how use case trees improve LLM-driven multi-agent architectures

some examples of the persona-driven, tech-agnostic solutions in agent architectures that use-case trees support

the importance of constraining LLM action with a control layer that governs agent activities, accounting for security, data sourcing, and issues like data lineage and provenance

the new Use Case Tree Work Group he is forming

the paradox in the semantic technology industry now of a lack of standards in a field with its roots in W3C standards



Jacobus' bio

Jacobus Geluk is a Dutch Semantic Technology Architect and CEO of agnos.ai, a UK-based consulting firm with a global team of experts specializing in GraphAI — the combination of Enterprise Knowledge Graphs (EKG) with Generative AI (GenAI). Jacobus has over 20 years of experience in data management and semantic technologies, previously serving as a Senior Data Architect at Bloomberg and Fellow Architect at BNY Mellon, where he led the first large-scale production EKG in the financial industry.



As a founding member and current co-chair of the Enterprise Knowledge Graph Forum (EKGF), Jacobus initiated the Data Product Workgroup, which developed the Data Product Ontology (DPROD) — a proposed OMG standard for consistent data product management across platforms. Jacobus can claim to have coined the term "Enterprise Knowledge Graph (EKG)" more than 10 years ago, and his work has been instrumental in advancing semantic technologies in financial services and other information-intensive industries.

Podcast intro transcript

This is the Knowledge Graph Insights podcast, episode number 26. In an AI landscape that will soon include huge groups of independent software agents acting on behalf of humans, we'll need solid mechanisms to guide the actions of those agents. Jacobus Geluk looks at this situation from the perspective of the data economy, specifically the data-products marketplace. He helped develop the DPROD specification that describes data products and is now focused on developing use-case trees t...
