Semantic Intermediary for Organizational Integration

1. Why Can’t We All Just Agree? Dave McComb August 11, 2010 Federal Data Architecture Subcommittee Semantic Arts

2. Your Current Situation (Greatly Simplified) • Each of your agencies has evolved, over long periods of time, complex systems • In aggregate each agency has at least tens of thousands, and mostly hundreds of thousands and some of you may have millions, of distinctions coded into those systems • Each agency already relies on more distinctions than anyone could possibly understand • And, you’ve been asked to “interoperate”

5. Desirable Attributes of a Semantic Intermediary • Simplicity • Coverage • Unambiguous • Specificity • Modular • Fractal

6. A candidate that meets these criteria • And is free • As in free speech • Available under Creative Commons License • And free beer • At no charge • gist.owl

10. Coverage

11. Coverage • An Enterprise Ontology we built recently contained 600 classes • All but 2 were derived from or defined in terms of gist

12. Unambiguous • Almost all these high level concepts are disjoint • Which means classes derived from them also cannot have overlapping/ ambiguous membership • This helps ontologists make some difficult but necessary decisions as they map their domain into the common

13. Unambiguous ? BankAccount GLAccount Account

14. Specific • gist itself and the classes derived from it have rigorous definitions

15. Modular (Each ontology is “human scale” ) gist Gist2/3 SM R&D FEI Div1 Div2

23. Summary • Semantic Integration is going to be greatly aided by having an intermediary that is: • Simple, to promote adoption • Broad enough to cover most of the concepts • Unambiguous to prevent promoting vagueness • Rigorous in its specification • Modular to allow mix and match • Fractal to allow people to understand it by degree www.semanticarts.com/gist Documentation ontologies.semanticarts.com/gist/gist.owl Ontology
