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 Projects AbstractMap 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 Projects AbstractMap AbstractMap Viewer

Current Projects AAG Conference Abstracts

data set –AAG Meetings –# 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

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

Current Projects / Future Plans Change Trajectory vs. Change Surface Michael Goodchild (UC Santa Barbara) [’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
