Scientific Data Integration... 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? ? Information Integration Geologic Map (Virginia) GeoChemical GeoPhysical (gravity contours) GeoChronologic (Concordia) Foliation Map (structure DB) “Complex Multiple-Worlds” Mediation domain knowledge Database mediation Data modeling Knowledge Representation: ontologies, concept spaces raw data GeoSciences Network

GEON-UTEP Towards Shared Conceptualizations: Data Contextualization via Concept Spaces

GEON-UTEP Rock Classification Ontology Composition Genesis Fabric Texture

GEON-UTEP Some enabling operations on “ontology data” Composition Concept expansion: what else to look for when asking for ‘Mafic’ what else to look for when asking for ‘Mafic’

GEON-UTEP Some enabling operations on “ontology data” Composition Generalization: finding data that is “like” X and Y finding data that is “like” X and Y

GEON-UTEP Ontology-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) Ontology-Enabled ApplicationOntology-Enabled Application

GEON-UTEP Amalgamating OWL Rocktype Ontologies OWL ontologies:OWL ontologies: –Geologic age –GSC’s hiearchies: –Composition –Texture –Fabric –Genesis –BGS: –All-in-one hierarchy Mappings:Mappings: –for now: synonyms only –next steps: more of OWL DL
