Scientific Data IntegrationScientific Data Integration ... Questions to Queries ...... Questions to Queries ...
What is the distribution and U/ Pb zircon ages of A-type plutons in VA? How about their 3-D geometry ?
How does it relate to host rock structures?

Ontology-Based GEON WorkbenchOntology-Based GEON Workbench
• Uploadable:Uploadable:– OWL ontologies
– OWL inter-ontology mappings (“articulations”)
– Data sets (shape files)
• ““Semantic Registration”Semantic Registration”– Link data set D with ontology O1
(w/ instance-based heuristic)
– Query D using ontology O2
– (e.g. rock classification: O1= GSC, O2=BGS)

• OWL ontologies:OWL ontologies:– Geologic age
– GSC’s hiearchies:
– Composition
– Texture

– Genesis
– BGS:
– All-in-one hierarchy
• Mappings:Mappings:– for now: synonyms
