CETIS 2007 Conference Semantics
A Semantic Infrastructure for Learning, Education and Training
by Tore HoelOslo University College/eStandardVicechair CEN/ISSS WS-LT
Slow uptake - great potentials
Why so slow?
• For organisational & semantical interoperability we need trust– Why are not vocabularies reused more often?
• RDF is easy to explain to machines
• Topic Maps is easy to explain to humans– But, it does not help much when we lack...
• Tools and demonstrators

What identity scheme is serving the Minitrue?
Kuling.netA community portal for local museums documenting their cultural heritage
Flexplearn - Dino Karabeg, UiOPolyscopic Topic Maps play the role of geographical maps
Motivation: 'information jungle'

Polyscopic information
The scope determines the view.
Three kinds of abstraction:
• Horizontal
• Vertical
• Structural
Conclusions
• Need for some simple recommendations how to facilitate exchange of ontologies, vocabularies etc.
• Identifiers, identifiers, identifiers – how do we create the semantic hub?
• Demonstrate the tools – and make them known!
Thanks!
