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
• Geographic/Cartographic/GIScience Perspectives on:– Metaphors
• map, landscape
– Technology• GIS
– Methods• objects vs. fields• visualizing change
– Challenges• computation• cognition

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 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
