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

[’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
