Mapping Science
• premise/promise of geogr., cartogr., GIScience
• past results
• current projects
• future plans
Premise/Promise of Geography, Cartography, GIScience
• Perspectives on:– Conceptualization
• discrete objects vs. continuous fields
– Metaphors • place, region, scale
– Methods• labeling• scale-dependence• visualizing change
– Technology• GIS
Past Results
AAG Meeting 1999: Self-Organizing Map + Hierarchical Clustering + Cluster Labeling
Past Results
AAG Meeting 1999: SOM + Term Dominance Landscape + K-means Cluster Labeling
Current ProjectsAbstractMap
• Problems addressed:– source data– loose coupling– interactivity
• AbstractMap System• AM Manager data input, preprocessing, DB mgmt.• AM Viewer interactive exploration, queries• AM Analyzer visual domain analysis, incl. temporal

Current ProjectsAAG Conference Abstracts
Current ProjectsAAG Conference Abstracts
• data set– AAG Meetings 1993-2002– # abstracts: 24,000+– source data: MS Word, PDF
• spatialization• 22,089 abstracts• 2,586 terms• 100x100 (10,000) neuron SOM• 100,000 training runs• approx. 1 week on Dual 2.2 GHz Xeon PC
AAG Meeting 1993 – 2002: Term Dominance Landscape
AAG Meeting 1993 – 2002: Term Dom. Landscape + Neuron Label Clusters
AAG Meeting 1993 – 2002: Term Dom. Landscape + Neuron Label Clusters
NAS Workshop on Uncertainty Visualization: 3 sessions w/ 3-4 speakers + 1 discussant
Current Projects / Future PlansChange Trajectory vs. Change Surface

[’85-’94] minus [’80-’89]
Another Interesting Question
What’s “interactivity” anyway?
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 / surfaces
– links between conference site and topics
• integrate across disciplines– map of science
