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
