The workshop was held Thursday, March 3 and Friday, March 4, 2005 at the San Diego Supercomputer Center on the campus of the University of California, San Diego. The two day workshop was to provide a forum for establishing the framework for a high level ontologic representation of planets, with an emphasis on the solid Earth. The anticipated research benefits of establishing ontologic frameworks range from registration of community databases for ease of access to complex integration queries anticipated for emerging science opportunities in planetary exploration, 4-D evolution of the earth, as well as environmental stewardship.

Geo-Ontology workshop

  • Current status of ontologic research in the earth sciences and its applications

  • Ontologies and Ontological Engineering ... D. L. McGuinness

    1. Discussion on building and managing complex and large ontologies

    2. Capabilities of the OWL language; Discussion on adopting a common AI technique for all earth science ontologies: W3C Ontology Web Language recommendation is quite useful. DLM suggests we should not go beyond the expressive power of OWL Dl for our representations if at all possible.

  • Analyzing the SWEET ontology as a planetary reference framework Current status of SWEET ... R. Raskin
    Discussion on SWEET objectives; integration with other ongoing earth science activities in building ontologies; interfaces with other major earth environments; addressing limitations of OWL for science ontologies, such as numeric processing; current status of modifications to SWEET.

  • Modifying SWEET to register lower level concepts and ontologies with an emphasis on the solid earth; issue of granularity

  • Registering and mapping datasets to ontology elements

  • Discussion of solid earth science Index terms as represented in ontologies: NASA GCMD; AGI; AGU; NADM

  • Creating a prototype high level solid earth ontology for additional research

  • Proof of Concept : highly visible application(s)

  • Plans for a research workshop on Geo-Ontology II: justification, objectives, location

  • Reading for the workshop: Deborah L. McGuinness. "Ontologies Come of Age". In Dieter Fensel, Jim Hendler, Henry Lieberman, and Wolfgang Wahlster, editors.
