Knowledge Domain Visualization
  • Why?
    • understand knowledge domains in terms of:
      • Past  how did this research area develop?
      • Present  who are the leading researchers and topics?
      • Future  what will have high priority for federal funding?
  • Who are the users?
    • non-specialists:
      • teaching tool
    • specialists:
      • find trends, emerging topics, potential collaborators
    • b/w specialists from different domains:
      • enable communication about knowledge domains
    • funding agencies
      • research impact analysis

Knowledge Domain Visualization
  • Geographic/Cartographic/GIScience Perspectives on:
    • Metaphors
      • map, landscape
    • Technology
      • GIS
    • Methods
      • objects vs. fields
      • visualizing change
    • Challenges
      • computation
      • cognition
aag abstracts 1993 2002 f rom unstructured to structured data
AAG abstracts 1993 – 2002from unstructured to structured data
  • Issues:
    • parse documents
      • begin/end
    • parse document components
      • metadata
        • author name, address, email
      • content
        • title, abstract text, keywords
    • variations in format between years
    • variations in format within years
    • author disambiguation
aag abstracts 1993 2002 interesting facts
AAG abstracts 1993 – 2002interesting facts
  • abstracts: 22,089
  • authors: 30,589
  • unique authors: ~ 13,521
    • disambiguation of author names difficult
      • same authors counted more than once
        • “Andre Skupin” versus “André Skupin”
      • multiple authors with same name
        • “Michael Smith” versus “Michael Smith”
  • max authors for one abstract: 17
      • Knight et al. (1999) A framework for integrated regional assessment of global climate change. (Penn State)
  • max abstracts for one author: 29
      • Kam-biu Liu, Louisiana State University

aag abstract database future work
AAG Abstract Database – Future Work
  • Tool development and deployment
    • AbstractMap System
      • AbstractMap Manager
      • AbstractMap Viewer
    • scalability to large data sets?
  • Tool application
    • time / geographic space / attribute space
      • cluster emergence/growth/abandonment
      • disciplinary evolution
      • institutional evolution
      • author trajectories
      • links between conference site and topics
    • integrate across disciplines
      • map of science
