User requirements
• Control over the paper collection
– Choose custom subset via query, then iteratively drill
down, filter, & refine
• Overview either as visualization or text statistics
– Orient within subset
• Easy to understand metrics for identifying
interesting papers
– Ranking & filtering
• Create groups & annotate with findings
– Organize discovery process
– Share results

Action Science Explorer
• Bibliometric lexical link mining to create a
citation network and citation context
• Network clustering and multi-document
summarization to extract key points
• Potent network analysis and visualization tools

2. Case study: Tree visualization
• Problem: Traditional 2D node-link diagrams of
trees become too large
• Solutions:
– Treemaps: Nested Rectangles
– Cone Trees: 3D Interactive Animations
– Hyperbolic Trees: Focus + Context
• Measures:
– Papers, articles, patents, citations,…
– Press releases, blog posts, tweets,…
– Users, downloads, sales,…

• Compelling demonstrations with familiar
applications help
• Many components to commercial success
• 2D visualizations w/spatial stability successful
• Term disambiguation & data cleaning are hard

– Groups (clusters, attributes, manual)
– Relationships between them
• User comments
– “We've never been able to see anything like this“
– “This is going to be huge"

5. STICK approach
• NSF SciSIP Program
– Science of Science & Innovation Policy
– Goal: Scientific approach to science policy
• The STICK Project
– Science & Technology Innovation Concept
Knowledge-base
– Goal: Monitoring, Understanding, and Advancing
the (R)Evolution of Science & Technology
Innovations
STICK approach cont…
• Scientific, data-driven way to track innovations
– Vs. current expert-based, time consuming
approaches (e.g., Gartner’s Hype Cycle, tire track
diagrams)
• Includes both concept and product forms
– Study relationships between
• Study the innovation ecosystem
– Organizations & people
– Both those producing & using innovations
