  1. A situated representation of Cyberinfrastructure resources Mark Gahegan and Bill Pike GeoVISTA Center, Department of Geography The Pennsylvania State University, USA The Geosciences Network (GEON): www.geongrid.org Learning Activities in Digital Libraries: www.dialogplus.org • This research is funded by: • NSF BCS-9978052, (HERO) • NSF ITR (EAR)-0225673 (GEON) • NSF/JISC Digital Libraries for Education • NSF ITR (BCS)-0219025 Human Environment Regional Observatories (HERO): www.hero.psu.edu

  2. Inspiration • “Knowledge keeps no better than fish” -- Alfred North Whitehead • “You cannot put your foot in the same stream twice” -- Heraclitus • “You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird... So let's look at the bird and see what it's doing -- that's what counts.” -- Richard Feynman

  3. We need systems that better describe the concepts we employ • Science is dynamic • Concepts used change and evolve • Concepts are situated … in place, in time, in tasks, in knowledge schemata, among individuals and communities • Thus, static, unsituated concepts (and ontologies and knowledge maps) will produce static science • We need methods to support dynamic and situated concept development, sharing, and application

  4. What’s in the soup? A nexus of knowledge structures (Whitehead, 1923)

  5. Situations in CyberInfrastructure

  6. 1. Situating e-resources in the knowledge nexus

  7. Seismic Analysis Concept Map(GEON: Randy Keller)

  8. …situated among data and methods

  9. …and people (individuals and communities)

  10. Perspectives example: (Articles and their authors, CiteSeer Communities in ConceptVista)

  11. End Questions?
