Industry Knowledge Graph™ Case Study
by Semantic Arts | Information Services & Media, Knowledge Graphs & Ontologies
Written by Michael Atkin In 1978 the owner of the New England Patriots made a famous commercial after his wife gave him a Remmington electric razor—“I liked the razor so much, I bought the company.” In the case of the […]
The year of the Knowledge Graph (2025)
by Dave McComb | Knowledge Graphs & Ontologies
2001, 2010, and 2012 were each billed as the year of the knowledge graph. Why 2025 looks different, from moves by ServiceNow, SAP, Samsung, and AWS to GraphRAG.
Team Building—The Importance of an Ontology
by Peter Winstanley | Knowledge Graphs & Ontologies
A shared vocabulary is what lets people across a company understand each other. Why building an enterprise ontology is as much a team-building exercise as a technical one.
From Labels to Verbs—Child’s Play!
by Peter Winstanley | Knowledge Graphs & Ontologies
Children learn labels first and verbs later, and enterprises tend to learn semantics the same way, starting with taxonomies. How gist’s relationships let you go straight to statements.
How a “User” Knowledge Graph Can Help Change Data Culture
by Dave McComb | Knowledge Graphs & Ontologies
How a knowledge graph of what an organization knows about its people allows access rules down to a single fact, and how it could cut the duplicated personal data that identity systems spread around.
How US Homeland Security Plans to Use Knowledge Graph
by Dave McComb | Knowledge Graphs & Ontologies
At the Data-Centric Architecture Forum, Ryan Riccucci of U.S. Border Patrol described the ontology Homeland Security is building to share data across the agency, starting with drone smuggling at the border.
Documents, Events, and Actions
by Dave McComb | Knowledge Graphs & Ontologies
Enterprise systems have long treated an invoice or a purchase order as if it were the event it records. Why data-centric accounting needs to tell the document, the event, and the action apart.
The Data-Centric Revolution: ABox Versioning
by Dave McComb | Knowledge Graphs & Ontologies
A query can break with no change to the ontology at all, when the way the data is used shifts. ABox versioning flags those changes, above all an average cardinality crossing 1.00, as major, minor, and patch versions.
The Data-Centric Revolution: Putting Knowledge Into Our Knowledge Graphs
by Dave McComb | Knowledge Graphs & Ontologies
Knowledge graphs hold plenty of data and little knowledge, while knowledge management has knowledge and nowhere to put it. How a knowledge graph can carry knowledge, track where it came from, and bring it forward when it's needed.
A Knowledge Graph for Mathematics
by Phil Blackwood | Knowledge Graphs & Ontologies
This blog post is for anyone interested in mathematics and knowledge representation as associated with career progression in today’s changing information eco-system. Mathematics and knowledge representation have a strong common thread; they both require finding good abstractions and simple, elegant […]
