Building a Multi-Year Database of AAG Conference Abstracts

André Skupin /Shujing Shu

Dept. of Geography / Dept. of Computer Science

University of New Orleans


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

Example: domain experts


Knowledge Domain Visualization (KDV)


Knowledge Domain Visualization

  • Geographic/Cartographic/GIScience Perspectives on:

    • Metaphors

      • map, landscape

    • Technology

      • GIS

    • Methods

      • objects vs. fields

      • visualizing change

    • Challenges

      • computation

      • cognition


Typical KDV versus KDV based on AAG


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 – 2002from unstructured to structured data


AAG abstracts 1993 – 2002n abstracts by year


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 Meeting 1992 – 2003: Term Dominance Landscape


    AAG Meeting 1992 – 2003: Term Dom. Landscape + Neuron Label Clusters


    AAG Meeting 1992 – 2003: Term Dom. Landscape + Neuron Label Clusters


    NAS Workshop on Uncertainty Visualization: 3 sessions w/ 3-4 speakers + 1 discussant


    2005 AAG Meeting: Sessions on “Mapping Humanity’s Knowledge in the Digital Domain”


    Author Change Surface – Michael Goodchild

    1970 - 1979

    1975 - 1984

    [’75-’84] minus [’70-’79]


    Author Change Surface – Michael Goodchild

    1980 - 1989

    1985 - 1994

    [’85-’94] minus [’80-’89]


    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
